Aims. Current levels of hip fracture morbidity contribute greatly to the overall burden on health and social care services. Given the anticipated ageing of the population over the coming decade, there is potential for this burden to increase further, although the exact scale of impact has not been identified in contemporary literature. We therefore set out to predict the future incidence of hip fracture and help inform appropriate service provision to maintain an adequate standard of care. Methods. Historical data from the Scottish Hip Fracture Audit (2017 to 2021) were used to identify monthly incidence rates. Established time series forecasting techniques (Exponential Smoothing and Autoregressive Integrated Moving Average) were then used to predict the annual number of hip fractures from 2022 to 2029, including adjustment for predicted changes in national population demographics. Predicted differences in service-level outcomes (length of stay and discharge destination) were analyzed, including the associated financial cost of any changes. Results. Between 2017 and 2021, the number of annual hip fractures increased from 6,675 to 7,797 (15%), with a rise in incidence from 313 to 350 per 100,000 (11%) for the at-risk population. By 2029, a combined average projection forecast the annual number of hip fractures at 10,311, with an incidence rate of 463 per 100,000, representing a 32% increase from 2021. Based upon these projections, assuming discharge rates remain constant, the total overall length of hospital stay following hip fracture in Scotland will increase by 60,699 days per annum, incurring an additional cost of at least £25 million per year. Approximately five more acute hip fracture beds may be required per hospital to accommodate this increased activity. Conclusion. Projection modelling demonstrates that hip fracture burden and incidence will increase substantially by 2029, driven by an ageing population, with substantial implications for health and social care services.

Objectives. Accurate characterisation of fractures is essential in fracture management trials. However, this is often hampered by poor inter-observer agreement. This article describes the practicalities of defining the fracture population, based on the Neer classification, within a pragmatic multicentre randomised controlled trial in which surgical treatment was compared with non-surgical treatment in adults with displaced fractures of the proximal humerus involving the surgical neck. Methods. The trial manual illustrated the Neer classification of proximal humeral fractures. However, in addition to surgical neck displacement, surgeons assessing patient eligibility reported on whether either or both of the tuberosities were involved. Anonymised electronic versions of baseline radiographs were sought for all 250 trial participants. A protocol, data collection tool and training presentation were developed and tested in a pilot study. These were then used in a formal assessment and classification of the trial fractures by two independent senior orthopaedic shoulder trauma surgeons. Results. Two or more baseline radiographic views were obtained for each participant. The independent raters confirmed that all fractures would have been considered for surgery in contemporaneous practice. A full description of the fracture population based on the Neer classification was obtained. The agreement between the categorisation at baseline (tuberosity involvement) and Neer classification as assessed by the two raters was only fair (kappa 0.29). However, this disparity did not appear to affect trial findings, specifically in terms of influencing the effect of treatment on the primary outcome of the trial. Conclusions. A key reporting requirement, namely the description of the fracture population, was achieved within the context of a pragmatic multicentre randomised clinical trial. This article provides important guidance for researchers designing similar trials on fracture management. Cite this article: H. H. G. Handoll, S. D. Brealey, L. Jefferson, A. Keding, A. J.

Background. With an ageing population, the incidence of traumatic injuries in those aged over 65 years is increasing. As a result, strategies for dealing with these patients must be developed. At present the standard management of open tibial fractures is described by the BOAST4 guidelines. We describe our experience of managing elderly patients presenting with open tibial fractures to our Major Trauma Centre. Methods. Patients were identified via prospectively collected national and departmental databases. Data collated included patient demographics, injury details, orthopaedic and plastic surgery operative details, and long term outcomes. Results. Between April 2013 and January 2016, 97 patients aged over 65 were admitted with open fractures, 38 of these were open tibial fractures. 10 patients required soft tissue reconstruction for Gustillo and Anderson IIIB tibial fractures (age range 67–95). In this group there were 4 midshaft (AO 42), 1 proximal (AO 41) and 5 distal (AO 43) fractures. Five patients were treated with internal fixation and 5 with circular frames. The median length of hospital stay was 33 days (range 16–113 days), 50% longer than comparable patients under 65. Four patients received pedicled local flaps and six underwent free tissue transfer. Of the 6 patients treated with free tissue transfer, one required pre-operative femoral angioplasty. There were no flap losses. Two patients had fasciocutaneous flaps, one an EDB flap and one gastrocnemius flap. All patients went on to unite and return to their pre-morbid weight-bearing status (2 using frames, 3 using sticks, 5 independent). Discussion. Although the literature suggests a significantly higher complication rate in elderly patients with open fractures, we have demonstrated comparable rates of flap survival and bony union to those observed in younger patients. Challenges are presented in terms of patient physiology and these must be carefully managed pre- and post-operatively. These challenges are reflected in the significantly longer length of stay in comparably injured patients under the age of 65

Introduction. Patient-reported outcome measures (PROMs) are increasingly being used to assess the quality of healthcare delivery in the United Kingdom. It is important when using PROMs to know the score of the background population against which any clinical intervention maybe benchmarked. The purpose of this study was to measure an elbow-specific PROM for the population of the South West Peninsula. Methods. We undertook a cross-sectional survey study of patients and healthcare professionals. Participants were asked to complete a simple demographic questionnaire and an Oxford Elbow Score for each elbow. Respondents with a history of elbow surgery, elbow injury, chronic elbow problems or an incomplete dataset were excluded from the study. Results. A total of 1782 respondents (3564 elbows) completed the survey. 574 questionnaires were excluded leaving 1208 individuals (2416 elbows) for analysis. The median scores for each decade group ranged between 46.74 and 48 out of 48. There was no significant difference in the score for age, gender or hand dominance. Conclusion. When using the Oxford Elbow Score to assess outcomes after surgery, a normal score should be used as the benchmark. This benchmark is independent of age, gender and hand dominance

INTRODUCTION. This study describes the prevalence of pain, functional loss and rotator cuff tears (RCTs) in a general population cohort. It is the first multidisciplinary assessment in such a cohort. METHODS. The Chingford cohort is a 19-year old longitudinal population study comprising 1003 women aged between 44 and 67 at baseline. To date 183 consecutive subjects (366) shoulders have been interviewed about their shoulders. Myometric strength assessment and high-definition ultrasound examination (US) have been performed on all shoulders. Additionally pain thresholds and perceptions of pain have been tested using quantitative sensory testing (QST) and a number of validated questionnaires, including the illness attitudes scale and the pain detect score. RESULTS. The population prevalence of at least one full-thickness RCT was 24%, with 19% being unilateral and 5% bilateral. Of the 366 shoulders: 56% had no tendon abnormality on ultrasound: Of which, 68% were asymptomatic, 23% had pain, and 24% had functional loss. 20% had abnormalities of the tendon-bone attachment: Of which, 56% were asymptomatic, 35.6% had pain and 36.1% had functional loss. 9% had a partial-thickness RCT: Of which, 53% were asymptomatic, 29% had pain and 38% had functional loss. 7% had a full-thickness RCT (less than 2cm): Of which, 58% were asymptomatic, 29% had pain and 29% had loss of function. 8% had a full-thickness RCT (greater than 2cm): Of which, 38% were asymptomatic, 55% had pain and 48% had functional loss. The pain and functional loss was significantly greater in the abnormal tendon-bone attachment group, and the full-thickness RCT (greater than 2cm) group, compared to those with no abnormality on high-definition ultrasound examination. Strength testing showed progressive weakness through all disease stages. Pain thresholds from the QST data will be presented. DISCUSSION. In a unique normal population-cohort study 44% of patients were found to have some form of degenerative tendon abnormality on high-definition ultrasound. Of these significant pain and/or loss of function was found in 48% of shoulders. High-definition US has allowed us to identify a group of tendons with an abnormality at the tendon bone interface. The pain and functional loss increases at this early stage and then only further increases once a tear is greater than 2cm. However over 50% remain asymptomatic

Nerve damage is a complication of THA and TKA procedures. The incidence of subclinical nerve injury following arthroplasty is unknown. The aim was to determine the prevalence of asymptomatic nerve deficits in an arthroplasty population group, and the incidence of post-operative changes in nerve function. A Secondary aim was to identify the nature of any deficits. And the association between nerve deficits and history of backache. A non-randomised prospective series of patients undergoing lower limb arthroplasty for osteoarthritis were studied at a single hospital. The peroneal nerve was investigated using nerve conduction in forty patients. Twenty patients had upper limb testing to differentiate between a polyneuropathy or isolated lower limb neuropathy. Nerve function deficits were detected in the peroneal nerve in fifteen patients pre-operatively and fifteen post-operatively, of those twelve had A waves detected suggestive of a generalised neuropathy. Ten patients who had upper limb testing had a conduction defect (five had asymptomatic Carpal tunnel). There was a positive correlation between presence of post-operative deficit and age(r=0.389, p=0.013). A negative correlation was found for presence of post-operative A waves and BMI(r=−0.370, p=0.019). The prevalence of pre-operative subclinical peroneal neuropathy is much higher than expected in this group (37.5%) of arthroplasty patients. There is a strong correlation between presence of post-operative conduction abnormalities and age. There is no relationship between peripheral neuropathy and history of backache or residual post-operative deficit

Dynamometric measurement of the grasp strength is commonly used in wrist assessment. On the other hand measurement of the pronation-supination (PS) strength has been few studied. The longitudinal forearm rotation needs integrity of the two radioulnar joints and of the antebrachial interosseous membrane. The strength developed during PS assesses also trophicity of pronator and supinator muscles. A PS dynamometer (Baseline ®, AREX) is now available for such measurements. The aims of this study were: 1) to study the best way to neutralize the shoulder movements of abduction-adduction, 2) to find the values of PS Strength in a healthy population, and 3) to study correlations between this PS force and several biometric items. A first series of measurements des PS strength was performed thanks to the Baseline dynamometer in 8 people, in association with two devices neutralizing the shoulder movements of abduction-adduction, in repeated campaigns allowed the authors to determine and keep the better one for optimal measurements following campaigns. To assess the normal values of PS Strength in a healthy population, 38 healthy volunteers from both genders and different ages, classified according their age class, from three different forearm position: neutral, from 90 ° of supination and 90 ° of pronation. Finally, statistical analysis looked for correlations between PS strength and some biometric data. Manipulations beginning from a neutral position of forearm were the most reliable. The mean strength within the whole studied sample (76 wrists, 17 male, 21 female) was 10.6 N.m (standard deviation SD 3.26) for the supination and 13.9 N.m (standard deviation 4.19) for the supination. The dominant side exhibited a PS strength superior by 7.5% to that of the non-dominant side. Male gender, the height and weight of the body, forearm circumference displayed positive relationships with PS strength. Mean values of PS strength, measured from a neutral forearm rotation and with the best device to neutralize the shoulder movements, in a healthy population of 38 volunteers, allowed the authors establishing reference values. They will allow precise comparisons between the values found in patients suffering from forearm and/or wrist pathology and the healthy population, taking into account the age, gender and hand dominance

INTRODUCTION. Patellar tendon (PT) autograft is an excellent choice repairing anterior cruciate ligament (ACL) ruptures. Published studies testing the biomechanical characteristics after plasty usually refer to grafts with 10mm wide. The thickness of PT and geometry of the patella have been overlooked. The purpose of this study was to understand the geometry of PT and patella in our population, regarding their use in Bone - Patellar Tendon - Bone (BTB) technique, in order to evaluate their biomechanical efficiency and study their relationship with anthropometric parameters. MATERIAL. 100 individuals (50/50) who underwent knee MRI (3-Tesla). Ages between 18–65years. METHODS. Retrospective study. Standardized protocol for measuring the PT and patella based in MRI images. Interview to obtain personal data. Statistical analysis using SPSS®. RESULTS. Sample (mean ±SD): age 41 ±14years, weight 73 ±12kg, height 167 ±10cm, BMI 26,04 ±4,13; length PT/patella −41,3 ±6,1mm/29,6 ±4,2 mm, width PT/patella −25,3 ±3,2mm/43,4 ±4,14mm; thickness PT −3,79 ±1,01mm/22,8 ±2,2mm; Men have thicker and wider patella and PT than women (p<0.001). The patella is also longer in males (p<0.001). There is statistical significant relationship between weight and height to width, thickness and length of PT and patella (p<0.01). Body Mass Index (BMI) doesn't have statistical correlation with geometry of the PT and patella. DISCUSSION. The PT remains as an excellent option in ACL repair. The anatomy and quality of the graft are essential to achieving good functional results. The choice of middle third tendon to the BTB plasty does not always correspond to the 10mm width, as used in most biomechanical tests. Also patellar integrity can be at risk (when collecting the bone block) if patella geometry is not considered. To our knowledge, there is only one similar study in literature, preformed in Asian individuals. CONCLUSION. Preoperatively accessing the geometry of Patella and PT can be crucial in obtaining efficient grafts and decreasing morbidity over the extensor mechanism

Introduction. In an ageing population the incidence of patients sustaining a neck of femur fracture is likely to rise. Whilst the neck of femur fracture is thought to be a pre-terminal event in many patients, there is little literature following this common fracture beyond 1 year. With improving healthcare and increasing survival rate, it is likely that a proportion of patients live to have subsequent fractures. However little is known about if these occur and what the epidemiology of these fractures are. Aim. To describe the epidemiology of fractures sustained over a ten year period in patients who had an “index” neck of femur fracture. Method. All patients from the Lothian region, who sustained a neck of femur fracture and were admitted to the Royal Infirmary of Edinburgh in Scotland between 01/01/2000 and 31/12/2000 were prospectively identified and had their orthopaedic notes and where appropriate death records retrospectively reviewed in Aug 2010, to identify further fractures and orthopaedic treatments. Patients admitted from without the Lothian region were excluded from the study. Other information regarding their pre-injury medical history, what surgery was performed, age, social status, co-morbidities and where relevant cause and date of death were recorded. Results. In the year 2000 there were 628 patients identified as having sustained a neck of femur fracture giving an incidence of 12/10,000/year. 534 (85%) of the 628 fractures were sustained by falls, with the remainder being direct trauma, pathological or an unknown cause. The mean age of patient at the time of sustaining the neck of femur fracture was 87.5 years old, with a range of 17 to 101 years old. 136 (21.7%) patients went on to sustain further fractures. The top five most frequent fractures involved the contralateral neck of femur (55; 31%), radius (34; 19%), humerus (24; 13.4%), ipsilateral femur (19; 10.6%) and tibia (10; 5.6%). 32 (23.5%) people sustained multiple fractures after the initial hip index fracture. 24% of patients had previously sustained some form of fracture prior to their index neck of femur fracture. Conclusion. Our results demonstrate that over a fifth of patients who sustain a neck of femur fracture will sustain a further fracture in the next ten years. Rather than regarding a neck of femur fracture as a terminal event, resources and support should be directed at preventing further fractures in this high risk population. As patients live longer and health care and the treatment of neck of femur fractures improves it is likely that the incidence of further fractures will rise. We believe our results will be useful for all departments treating neck of femur fractures

Introduction. Spinal aBMD only explains 50–80% of vertebral strength, and the application of aBMD measurements in isolation cannot accurately identify individuals who are likely to eventually experience bone fracture, due to the low sensitivity of the test. For appropriate treatment intervention, a more sensitive test of bone strength is needed. Such a test should include not only bone mineral density, but also bone quality. Quantitative computed tomography-based finite element methods (QCT/FEM) may allow structural analyses taking these factors into consideration to accurately predict bone strength (PBS). To date, however, basic data have not been reported regarding the prediction of bone strength by QCT/FEM with reference to age in a normal population. The purpose of this study was thus to create a database on PBS in a normal population as a preliminary trial. With these data, parameters that affect PBS were also analyzed. Methods. Participants in this study comprised individuals who participated in a health checkup program with CT at our hospital in 2009. Participants included 217 men and 120 women (age range, 40–89 years). Exclusion criteria were provided. Scan data of the second lumber vertebra (L2) were isolated and taken from overall CT data for each participant obtained with simultaneous scans of a calibration phantom containing hydroxyapatite rods. A FE model was constructed from the isolated data using Mechanical Finder software. For each of the FE models, A uniaxial compressive load with a uniform distribution and uniform load increment was applied. For each participant, height and weight were measured, BMI was calculated. Simple linear regression analysis was used to estimate correlations between age and PBS as analyzed by QCT/FEM. Changes in PBS with age were also evaluated by grouping participants into 5-year age brackets. One-way analysis of variance was used to compare average PBS for participants in each age range. Mean PBS in the 40–44 year age range was taken as the young adult mean (YAM). The ratio of mean PBS in each age group to YAM was calculated as a percentage. A multivariate statistical technique was used to determine how PBS was affected by age, height, weight, and BMI. Result/Discussion. Mean PBS was lower in women than in men for all age ranges. PBS in men and women significantly decreased with age. Simple linear regression between age and PBS showed the annual rate of decline in PBS was 55 N/year in men and 164 N/year in women. Mean PBS in the 75–79 year age range was 77% of YAM in men and in women, that in the 70–79 year age range was 47% of YAM. PBS was strongly dependent on age, while physical status had less effect

A retrospective analysis of all paediatric patients admitted to Camp Bastion Role 3 between June 2006 and March 2013 was conducted from the UK trauma database. Patient demographics, mechanism of injury, anatomical distribution of injury and treatment are described.

Two hundred and ninety eight children were admitted, 225 males with a median age of 9 years old. The highest number of cases (78) was recorded in 2011. Overall there were 55 fatalities (85.6% male). Most injuries were by IED (68% of cases) with 74% requiring operative intervention. Seventy-four percent of casualties had three or more anatomical regional injuries. Whilst the most commonly injured region was the lower limb (78%), head injuries were seen in 41%, abdominal injuries in 48% and thorax injuries in 44%. Debridement (including amputations) (59.4%) and laparotomy (30.6%) were the commonest operations performed. Sixty percent of cases were in theatre within one hour of arrival. Amongst survivors the mean ISS score was 17 and amongst fatalities 43; NISS 22 and 51; RTS 5.45 and 2.91.

Paediatric blast injuries represent a significant burden to medical facilities in contemporary conflict. Whilst limb injuries predominate, the proportion of head and torso injuries is higher than seen in adult blast injuries.

Hip fracture is a global public health problem. The National Hip Fracture Database provides a framework for service evaluation in this group of patients in the United Kingdom, but does not collect patient-reported outcome data and is unable to provide meaningful data about the recovery of quality of life.

We report one-year patient-reported outcomes of a prospective cohort of patients treated at a single major trauma centre in the United Kingdom who sustained a hip fracture between January 2012 and March 2014.

There was an initial marked decline in quality of life from baseline measured using the EuroQol 5 Dimensions score (EQ-5D). It was followed by a significant improvement to 120 days for all patients. Although their quality of life improved during the year after the fracture, it was still significantly lower than before injury irrespective of age group or cognitive impairment (mean reduction EQ-5D 0.22; 95% confidence interval (CI) 0.17 to 0.26). There was strong evidence that quality of life was lower for patients with cognitive impairment. There was a mean reduction in EQ-5D of 0.28 (95% CI 0.22 to 0.35) in patients <  80 years of age. This difference was consistent (and fixed) throughout follow-up. Quality of life does not improve significantly during recovery from hip fracture in patients over 80 years of age (p = 0.928). Secondary measures of function showed similar trends.

Hip fracture marks a step down in the quality of life of a patient: it accounts for approximately 0.22 disability adjusted life years in the first year after fracture. This is equivalent to serious neurological conditions for which extensive funding for research and treatment is made available.

Over the last few decades, the All-Poly Monoblock Tibia has been relegated to a minimum use in the major healthcare systems of the western world. The main reason for this has been the perception that this tibial component is inferior in its ability to withstand stresses. This perception originated and subsequently gained ground, due to certain historical reasons, leading to the widespread use of the modular metal-backed tibial component despite a higher cost. The recent economic downturn has enforced even the rich western healthcare systems to look for cost-effective solutions. The author works in India, where the society is still highly price-sensitive and takes value for money very seriously. Further, the routine ADL of the Indian population requires them to adopt high flexion postures such as cross-legged sitting and squatting. The author has used the All-Poly Tibia extensively, which is the most economical of tibial components. Further, he has developed a surgical technique which has resulted in his patients achieving high flexion (greater than 135 degrees) in more than 75% cases. This paper presents the 10 year results of a series of 500 cases of Primary TKR in which the All-Poly Monoblock Tibia had been used. All the patients had cross-legged sitting activity as part of their ADL, thus presumably generating significant pressures on the joint surfaces. Of the original 500 cases, we could follow up 434 cases. We report a 96% survival rate of the implant in this series. There was not a single aseptic plastic failure. The revisions required were due to infection, peri-prosthetic fracture, and instability. The message being conveyed in this paper is that the All-Poly Tibia is a very cost-effective solution in routine Primary TKRs, and is able to deliver excellent long-term results even in high stress situations like cross-legged sitting activity. It would offer a huge cost savings to the healthcare system if the Orthopaedic Surgeons start using this implant more frequently

Slipped capital femoral epiphysiolysis (SCFE) is a rare condition with a unknown aetiopathogenesis. An early diagnosis and treatment is essential to minimize premature degeneration of the joint. The authors reviewed the cases treated between 1980 and 2005 in our institution. This study was aimed at evaluating patients with hip epiphysiolysis surgically treated by canullated screws or pinning and previously controlled by short-term follow-up, in order to evaluate radiographic medium/ long term evolution, looking for evidence of degenerative arthritis or femoroacetabular impingement.

We performed a retrospective review of the clinical notes and radiographs of all patients with slipped upper femoral epiphysis who were surgically treated at our institution between January 1980 and December 2005. These patients performed radiographs to detect evidence of osteonecrosis, chondrolysis, degenerative arthritis or femoroacetabular impingment. To grade the radiological osteoarthritic changes the grading system of Kellgren and Lawrence was used. These changes were correlated with the existence of femoroacetabular impingement. The radiological results were correlated with the Loder'sclassification of stability and the morphological classification.

43 patients were reviewed, corresponding to 47 treated hips. AP and Lowenstein x-ray views were taken in all patients. The alfa angle and the head-shaft angle were measured in the Lowenstein view (frog-leg).

Of 16 patients with impingement only 1 patient didn't present pistol grip deformity. 4 contralateral hips also presented the deformity. The mean alfa angle was 99,4.

43% of the patients with unstable hips have impingment. In stable hips this percentage is of 35%.

The Patrick test was positive in 30% of the hips with SCFE and only 17% of the unafected hips. The Kellgren and Lawrence scale was very diferent between trhe SCFE and control groups, with 43% grade 2, 17% grade 3 and 6% grade 4, versus 30% grade 2, 6% grade 3 and 0% grade 4.

Some patients show bilateral pistol grip deformity and clinical signs of impingment, despite only having one hip with SCFE

The hip fracture burden on health and social care services in Scotland is anticipated to increase significantly, primarily driven by an ageing population. This study forecasts future hip fracture incidence and the annual number of hip fractures in Scotland until 2029. The monthly number of patients with hip fracture aged ≥ 50 admitted to a Scottish hospital between 01/01/2017 and 31/12/2021 was identified through data collected by the Scottish Hip Fracture Audit. This data was analysed using Exponential Smoothing and Auto Regressive Integrated Moving Average forecast modelling to project future hip fracture incidence and the annual number of hip fractures until 2029. Adjustments for population change were accounted for by integrating population projections published by National Records of Scotland. Between 2017 and 2021 the annual number of hip fractures in Scotland increased from 6675 to 7797, with a respective increase in hip fracture incidence from 313 to 350 per 100,000. By 2029, the averaged projected annual number of hip fractures is 10311, with an incidence rate of 463 per 100,000. The largest percentage increase in hip fracture occurs in the 70-79 age group (57%), with comparable increases in both sexes (30%). Based upon these projections, overall length of stay following hip fracture will increase from 142713 bed days per annum in 2021, to 203412 by 2029, incurring an additional cost of over £25 million. Forecast modelling demonstrates that the annual number of hip fractures in Scotland will rise substantially by 2029, with considerable implications for health and social care services

The aim was to predict the number and incidence of distal radius fractures in Scotland over the next two decades according to age group, categorised into under 65yrs(65) and 65yrs and older (65), and estimate the potential increased operative burden. The number of distal radius fractures in Scotland was isolated from the Global Burden of Disease database and this was used, in addition to historic population data and published population estimates, to create a multivariable model allowing incorporation of age group, sex and time. A Negative Binomial distribution was used to predict incidence in 2030 and 2040 and calculate projected number of fractures. A 20.4% operative intervention rate was assumed (local data). In terms of number of fractures, there was a projected 61% rise in the 65 group with an overall increase of 2099 fractures per year from 3417 in 2020 (95% confidence interval (CI) 2960 – 3463) to 5516 in 2040 (95% CI 4155 – 5675). This was associated with 428 additional operative interventions per year for those 65yrs. The projected increase between 2020 and 2040 was similar in both sexes (60% in females, 63% in males), however the absolute increase in fracture number was higher in females. There was a 4% projected fall in the number of fractures in those 65. Incidence of distal radius fractures is expected to considerably increase over the next two decades due to a projected increase in the number of fractures in the elderly. This has implications for associated morbidity and healthcare resource use

Patellofemoral instability (PFI) is a common cause of knee pain and disability in the paediatric population. Patella alta, lateralised tibial tubercle, medial patellofemoral ligament (MPFL) deficiency, genu valgum and trochlear dysplasia are well known risk factors. A prospective database was created including patients referred through our physiotherapy pathway following first-time patella dislocation. Patella alta and lateralisation of the tibial tuberosity was treated with a Fulkerson-type tibial tubercle osteotomy(TTO). Medial patellofemoral ligament was reconstructed using quads tendon autograft pull-down technique. A modified Sheffield protocol was used postoperatively allowing weightbearing in a hinged knee brace. Forty patients were identified with 8 patients having bilateral presentations. Male to female ratio was 12:28 with an age range of 4–17 years. Eight patients had congenital PFI, five patients acquired PFI through traumatic patella dislocation and twenty-seven patients developed PFI from recurrent dislocations. Structural abnormalities were found in 38(95%) of patients. Patella alta (Caton-Deschamps index >1.2) was identified in 19(47%) patients, genu valgum in 12(30%) patients, increased tibial tubercle-trochlear groove distance(TT-TG>20mm) was present in 9(22.5%) patients and persistent femoral anteversion(> 20 deg) in 7(17%) patients. Eight patients were treated with TTO and MPFL reconstruction, three patients with MPFL reconstruction alone and five patients had guided growth for genu valgum correction. Ten patients are awaiting surgery. No postoperative patients had recurrence of PFI at their latest follow up. PFI is a common problem in the adolescent paediatric population with identifiable structural abnormalities. Correcting structural pathology with surgery leads to predictable and safe outcomes

NICE Guidelines suggest patients should be offered a Total Hip Replacement (THR) rather than Hemiarthroplasty for a displaced intracapsular hip fracture. We investigated outcomes of patients aged 40–65 who received a THR or Hemiarthroplasty following a traumatic intracapsular hip fracture and had either high-risk (Group 1) or low-risk (Group 2) alcohol consumption (>14 or <14 units/week respectively). This was a retrospective study (April 2008 – December 2018) evaluating patients who underwent THR or Hemiarthroplasty in Greater Glasgow and Clyde. Atraumatic injuries, acetabular fractures, patients with previous procedures on the affected side and those lost to follow up were excluded. Analysis of length of admission, dislocation risk, periprosthetic fractures, infection risk, and mortality was conducted between both cohorts. Survival time post-operatively of Group 1 patients with a THR (61.9 months) and Hemiarthroplasty (42.3 months) were comparable to Group 2 patients with a THR (59 months) and Hemiarthroplasty(42.4 months). Group 1 patients with THR had increased risk of dislocation (12.9%; p=0.04) compared to those that received Hemiarthroplasty (2.5%). Group 1 Hemiarthroplasty patients had increased wound infection risk (11.6%) compared to Group 2 (3.7%). In conclusion, we found that amongst our population the life expectancy of a post-operative patient was short irrespective of whether they had high or low-risk alcohol consumption. A hip fracture may represent increased frailty in our study population. The Group 1 THR cohort presented a higher risk of hip dislocation and periprosthetic fracture. With this in mind, Hemiarthroplasty is a more cost-effective and shorter operation which produces similar results

Aims. The aim of this study was to describe the demographic details of patients who sustain a femoral periprosthetic fracture (PPF), the epidemiology of PPFs, PPF characteristics, and the predictors of PPF types in the UK population. Methods. This is a multicentre retrospective cohort study including adult patients presenting to hospital with a new PPF between 1 January 2018 and 31 December 2018. Data collected included: patient characteristics, comorbidities, anticoagulant use, social circumstances, level of mobility, fracture characteristics, Unified Classification System (UCS) type, and details of the original implant. Descriptive analysis by fracture location was performed, and predictors of PPF type were assessed using mixed-effects logistic regression models. Results. In total, 720 femoral PPFs from 27 NHS sites were included. PPF patients were typically elderly (mean 79.9 years (SD 10.6)), female (n = 455; 63.2%), had at least one comorbidity (n = 670; 93.1%), and were reliant on walking aids or bed-/chair-bound prior to admission (n = 419; 61.7%). The study population included 539 (74.9%) hip PPFs, 151 (21.0%) knee PPFs, and 30 (4.2%) dividing type PPFs. For hip (n = 407; 75.5%) and knee (n = 88; 58.3%) arthroplasty UCS B type fractures were most common. Overall, 556 (86.2%) were treated in the presenting hospital and 89 (13.8%) required transfer for treatment. Female sex was the only significant predictor of fracture type (A/B1/C type versus B2/B3) for femoral hip PPFs (odds ratio 0.61 (95% confidence interval 0.41 to 0.91); p = 0.014). Sex, residence type, primary versus revision implant PPF, implant fixation, and time between arthroplasty and PPF were not found to predict fracture type for hip PPFs. Conclusion. This multicentre analysis describes patient and injury factors for patients presenting with femoral PPFs to centres across the UK. These patients are generally elderly and frail, comparable to those sustaining a hip fracture. These data can be useful in planning future services and clinical trials.

Aims. This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality. Methods. Data on 37,394 hip fractures in the Norwegian Hip Fracture Register from January 2014 to December 2018 were linked to data from the Norwegian Patient Registry, Statistics Norway, and characteristics of acute care hospitals. Cox regression analysis was performed to estimate risk factors associated with mortality. The Wald statistic was used to estimate and illustrate relative importance of risk factors, which were categorized in modifiable (healthcare-related) and non-modifiable (patient-related and socioeconomic). We calculated standardized mortality ratios (SMRs) comparing deaths among hip fracture patients to expected deaths in a standardized reference population. Results. Mean age was 80.2 years (SD 11.4) and 67.5% (n = 25,251) were female. Patient factors (male sex, increasing comorbidity (American Society of Anesthesiologists grade and Charlson Comorbidity Index)), socioeconomic factors (low income, low education level, living in a healthcare facility), and healthcare factors (hip fracture volume, availability of orthogeriatric services) were associated with increased mortality. Non-modifiable risk factors were more strongly associated with mortality than modifiable risk factors. The SMR analysis suggested that cumulative excess mortality among hip fracture patients was 16% in the first year and 41% at six years. SMR was 2.48 for the six-year observation period, most pronounced in the first year, and fell from 10.92 in the first month to 3.53 after 12 months and 2.48 after six years. Substantial differences in median survival time were found, particularly for patient-related factors. Conclusion. Socioeconomic, patient-, and healthcare-related factors all contributed to excess mortality, and non-modifiable factors had stronger association than modifiable ones. Hip fractures contributed to substantial excess mortality. Apparently small survival differences translate into substantial disparity in median survival time in this elderly population.
