Purpose. To identify the modes of failure after total knee arthroplasty (TKA) in patients ≤ 55 years of age and to compare with those ≥ 56 years of age in patients who underwent revision TKA. Materials and Methods. We retrospectively reviewed 256 revision TKAs among patients who underwent TKA for knee osteoarthritis between January 1992 and December 2012. The causes of TKA failure were analyzed and compared between those ≤ 55 years of age and those ≥ 56 years of age. The age at the time of primary surgery was ≤ 55 years in 30 patients (31 knees) and ≥ 56 years in 210 patients (225 knees). Results. A total of 453 TKAs were performed in ≤ 55-year-old patients between 1992 and 2012. Of these, 31 cases (7%) were revised. Their mean age was 50.6 years (range, 40 to 55 years) at primary surgery and the interval from primary TKA to revision was 8.6 years (range, 1 to 17 years). In the ≤ 55 years of age group, the most common modes of TKA failure was polyethylene wear in 14 cases (45%) followed by infection in 8 cases (26%) and component loosening in 5 cases (17%). The other conditions led to TKA failure were stiffness, periprosthetic fracture, malalignment, and osteolysis in one case each (3%). Of the 11,363 TKAs that were performed in ≥ 56-year-old patients, 225 cases (2%) required a revision. The mean interval between the operations was 5.3 years (range, 0.1 to 18 years). The major modes of failure of primary TKA include polyethylene wear in 99 cases (44%), infection in 91 cases (40%), and component loosening in 26 cases (12%). In both groups, the most common cause of failure was polyethylene wear, which was followed by infection and component loosening. There were relatively lower infection rate and higher loosening rate in patients ≤ 55 years of age, but the difference was not statistically significant (p > 0.05). The mean interval between the operations was shorter in the ≥ 56 years of age group (5.3 years; range, 0.1 to 18 years) than in the younger patient group (8.6 years; range, 1 to 17 years), but there was no notable intergroup difference (p > 0.05). Conclusion. The main modes of failure after TKA in patients ≤ 55 years of age were polyethylene wear, infection and loosening, and there was no significant difference in the modes of failure after TKA between the two groups

Surgical management of younger patients requiring primary total hip arthroplasty remains challenging due to their activity level, physical demands and the need for longevity of implanted components. There is a debate regarding the most suitable means of component fixation in this difficult group. We undertook a retrospective review of a sequential group of patients who underwent uncemented primary total hip arthroplasty, were 55 years or younger at the time of surgery, and who were currently a minimum of 5 years post operation. From January 2004 to December 2006 we performed 86 primary uncemented THRs in 71 young adults. The ages ranged from 18 to 55 years with a mean of 42.9 years at the time of operation. At last review, 8 patients (9 hips) had died from unrelated causes, and 16 patients (19 hips) were lost before completing 5 years of follow-up. Complications included 1 peri-operative mortality, 10 intra-operative femoral calcar fractures, 1 revision for sepsis, 1 dislocation and 1 DVT. At a minimum of 5 years post operation there were no revisions for aseptic loosening. Uncemented primary total hip arthroplasty in patients 55 years or younger yields good results at a minimum of 5 years. NO DISCLOSURES

Orthopaedics has been earmarked as one of the specialties that could make significant savings in the National Health Service. A large number of young adults are receiving total hip replacements and there has been a trend towards using uncemented implants. We describe the clinical and functional results at minimum 19 year follow up of cemented total hip replacements in patients under the age of fifty-five in our health region between 1990 and 1997. 104 cemented THRs performed in 100 patients under 55 years were included in this study. The follow-up data had been collected prospectively in the University database. 88.46% hips showed good to excellent results at final follow-up with a mean Harris hip score of 87.9±8.64. Revision was performed in 2 hips (1.92%), one for aseptic acetabular loosening and the other for late haematogenous infection. Probable radiological loosening was seen in 14 acetabular components (14.89%) and 4 femoral components (4.25%) at final follow-up. The mean rate of acetabular wear was 0.12mm/year and was not influenced by gender or diagnosis. The mean follow-up was 21.68±2.11 years (range 19 to 26 years) and the survivorship at 19 years was 98.07%. The GIRFT report looked at the economic aspect of implant selection and found that the cost of uncemented implants was almost double that of the cemented implants. Savings of atleast £10 million a year can be made if cemented implants were used. We recommend that in a publically funded health system like the NHS, cemented implants can be used in patients under 55 with good long term functional outcomes and large savings in the healthcare costs

Introduction

Bony tumours of the foot account for approximately 3% of all osseous tumours. However, literature regarding os calcis and talar tumours comprises individual case reports, short case series or literature reviews with no recent large series.

Aim

Alumina ceramic on ceramic bearings in total hip arthroplasty (THA) may reduce the prevalence of osteolysis due to its properties of low wear and chemical inertness. This is critical in the younger patient population as they place increased demands over a longer period. This study reports on the clinical and radiographic outcomes of a series of modern cementless ceramic on ceramic THA at a minimum of 10 years in this younger group.

Abstract. Cemented total hip arthroplasty (THA) in the younger patient has historically been associated with higher wear and revision rates. We carried out a retrospective study of a prospectively collected database of patients at Wrightington hospital undergoing cemented THA under 55 years of age to determine acetabular wear and revision rates. Between August 2005 and December 2021 a cohort of 110 patients, 56 males and 54 females, underwent Cemented Total Hip Replacement through a posterior approach. Mean age at operation was 50yrs (35–55). The mean follow up was 6 years 9 months (0–16 years). 3 patients were lost to follow-up. Of the remaining 107 patients, Conventional and cross lined polyethylene were used in 54 and 53 patients respectively. Ceramic heads were used in 102 patients. 22.225mm and 28mm heads were used in 60 and 47 patients respectively. Clinical outcomes were assessed by Merle d'Aubigne and Postel scores which showed significant functional improvement. Linear wear was measured on plain radiographs using TRAUMA CAD and cup loosening was assessed by classification of Hodgkinson et al. No cases were revised during the observed follow up period. The mean wear rate in conventional and crosslinked polyethylene cups were 2.31mm (0.1–4.6) and 1.02mm (0.1–2.6) respectively. Cemented THA with both conventional and crosslinked polyethylene provides excellent survival rates in adults under the age of 55 years and crosslinked polyethylene may further improve these results due to improved wear rates

Reverse Total shoulder arthroplasty (RTSA) was initially introduced to treat rotator cuff arthropathy. With proven successful long-term outcomes, it has gained a noteworthy surge in popularity with its indications consequently being extended to treating various traumatic glenohumeral diseases. Several countries holding national registries remain a guide to the use the prosthesis, however a notable lack of epidemiological data still exists. More so in South Africa where the spectrum of joint disease related to communicable diseases such as HIV and tuberculosis may influence indications and patient demographics. By analysing the epidemiology of patients who underwent RTSA at our institution, we aimed to outline the local disease spectrum, the patients afflicted and indications for surgery. A retrospective review of all patients operated within the sports unit between 1 January 2019 and 31 December 2022 was conducted. An analysis of the epidemiological data pertaining to patient demographics, diagnosis, indications for surgery and complications were recorded. Included in the review were 58 patients who underwent primary RTSA over the 4-year period. There were 41 females and 17 male patients, age <55 years (n= 14) >55 years (n=44). The indications included 23 rotator cuff arthropathy (40%), 12 primary glenohumeral osteoarthritis (OA) (20%), 10 avascular necrosis (AVN) humeral head (17%), 7 inflammatory OA (12%), 4 chronic shoulder dislocation (7%) and 2 sequalae of proximal humerus fractures (4%). The study revealed RTSA being performed in patients older than 55 years of age, the main pathologies included rotator cuff arthropathy and primary OA, however AVN and shoulder dislocations secondary to trauma contributed significantly to the total tally of surgeries undertaken. This highlights the disease burden of developing countries contributing to patients presenting for RTSA

The aim of this study was to determine the long term 20 year survival and outcomes of high tibial osteotomy (HTO). 100 consecutive subjects underwent HTO under the care of a single surgeon between 2000 and 2002, consented to participation in a prospective study and completed preoperative WOMAC scores. Subjects were reviewed at 10 years, and again at a minimum of 20 years after surgery. PROMS included further surgery, WOMAC scores, Oxford Knee Score (OHS), KOOS, and EQ-5D, and satisfaction with surgery. 20 year survival was assessed with Kaplan-Meir analysis, and failure defined as proceeding to subsequent knee arthroplasty. The mean age at HTO was 50 years (range 26-66), and 72% were males. The 5, 10, and 20 year survival of the HTO was 88%, 76%, 43% respectively. On multiple regression analysis HTO failure was associated with poor preoperative WOMAC score of 45 or less (HR 3.2, 95% CI 1.7-6.0, p=0.001), age at surgery of 55 or more (HR 2.3, 95% CI 1.3-4.0, p=0.004), and obesity (HR 1.9, 95% CI 1.1-3.4, p=0.023). In patients who met all criteria of preoperative WOMAC score of 45 or less, age <55 years and body mass index of <30 HTO survival was 100%, 94%, and 59% at 5, 10 and 20 years respectively. Of those who had not proceeded to TKA the mean Oxford Score was 40, KOOS Pain score was 91 and KOOS function score was 97. 97% reported they were satisfied with the surgery and 88% would have the same surgery again under the same circumstances. At 20 years after HTO 43% had not proceeded to knee arthroplasty, and were continuing to demonstrate high subjective scores and satisfaction with surgery. HTO survival was higher in those under 55 years, with BMI <30 and baseline WOMAC score of >45 at 59% HTO survival over 20 years. HTO may be considered a viable procedure to delay premature knee arthroplasty in carefully selected subjects

Introduction. Patients ≤ 55 years have a high primary TKA revision rate compared to patients >55 years. Guided motion knee devices are commonly used in younger patients yet outcomes remain unknown. Materials and Methods. In this sub-group analysis of a large multicenter study, 254 TKAs with a second-generation guided motion knee implant (Journey II Bi-Cruciate Stabilized Knee System, Smith & Nephew, Inc., Memphis) were performed between 2011–2017 in 202 patients ≤ 55 years at seven US and three European sites. Revision rates were compared with Australian Joint Registry (AOANJRR) 2017 data. Results. Average age 49.7 (range 18–54); 56.4% females; average BMI 34 kg/m. 2. ; 67.1% obese; patellae resurfaced in 98.4%. Average follow-up 4.2 years; longest follow-up six years; 27.5% followed-up for ≥ five years. Of eight revisions: total revision (one), tibial plate replacements (three), tibial insert exchanges (four). One tibial plate revision re-revised to total revision. Revision indications were mechanical loosening (n=2), infection (n=3), peri-prosthetic fracture (n=1), and instability (n=2). The Kaplan-Meier revision estimate was 3.4% (95% C.I. 1.7% to 6.7%) at five years compared to AOANJRR rate of 6.9%. There was no differential risk by sex. Discussion. Reasons for high TKA revision rates in younger patients remain unknown. Conclusion. The revision rate of the second-generation guided motion knee system is lower in younger patients compared to registry controls

Purpose. Femoroacetabular impingement (FAI) may contribute to the development of early onset hip osteoarthritis (OA). A cam lesion (or pistol grip deformity) of the proximal femur reduces head-neck offset resulting in cam type FAI. The alpha angle is a radiographic measurement recommended for diagnosis of cam type FAI. The purpose of this study was to determine if patients that develop end stage hip OA prior to 55 years of age have radiographic evidence of cam type FAI. Method. The anteroposterior (AP) pelvis and lateral hip radiographs of 244 patients (261 hips) who presented to our institution for hip arthroplasty or hip fracture fixation between 2006 and 2008 were retrospectively reviewed. Three cohorts were compared: 1) patients with end stage hip OA < 55 years old (N=76); 2) patients with end stage hip OA > 55 years old (N=84); 3) hip fracture patients > 65 years old without radiographic evidence of hip arthritis were used as controls (N=101). Patients with inflammatory arthritis, avascular necrosis and post-traumatic hip OA were excluded. Alpha angles were measured on the AP pelvis and lateral radiographs by three coauthors using ImageJ 1.43 software (National Institutes of Health, USA). For patients with end stage hip OA, AP alpha angles were measured on both the hip with OA and the contralateral hip. Lateral alpha angles were measured only on the hip with OA. For patients with hip fracture, AP alpha angles were measured on the non-fractured hip and lateral alpha angles were measured on the fractured hip. A one-way ANOVA with post hoc Tukeys HSD test was used to compare the AP and lateral alpha angles for the three cohorts. Results. The intraclass correlation coefficient (ICC) for the three coauthors measuring AP and lateral alpha angles was 0.85 and 0.86 respectively, indicating excellent inter-rater agreement. Patients < 55 years old with end stage hip OA had the largest AP and lateral alpha angles (82.711.6 degrees AP and 63.918.5 degrees lateral). These angles were significantly larger (p<0.01 for both comparisons) than patients > 55 years old with end stage hip OA (71.717.8 degrees AP and 55.518.0 degrees lateral) and hip fracture patients without hip OA (52.710.9 degrees AP and 44.411.4 degrees lateral). Comparing AP alpha angles of the contralateral hips, the mean AP alpha angle for patients < 55 years old with hip OA (70.813.2 degrees) was significantly larger (p=0.04) than patients > 55 years old with hip OA (64.516.2 degrees) which in turn was significantly larger (p<0.01) than the hip fracture patients (52.710.9 degrees). Conclusion. Patients < 55 years old with hip OA had the largest mean AP and lateral alpha angles, significantly larger than patients > 55 years old with hip OA and hip fracture patients without hip OA. Thus young patients with end stage hip OA do have radiographic evidence of cam type FAI. Furthermore, this case-controlled study suggests that cam type FAI may contribute to the development of early onset hip OA

Introduction. Hip resurfacing arthroplasty (HRA) is an alternative to traditional total hip arthroplasty (THA) in young active patients. While comparative implant survival rates are well documented, there is a paucity of studies reporting the patient mortality rates associated with these procedures. The purpose of this study was to evaluate the mortality rates in patients age 55 years and younger who underwent HRA versus THA and to assess whether the type of operation was independently associated with mortality. Patients and Methods. The database of a single high-volume surgeon was reviewed for all consecutive patients age 55 years and younger who underwent hip arthroplasty between 2002 and 2010. HRA became available in the United States in 2006. This yielded 504 patients who had undergone HRA from 2006 to 2010 and 124 patients who had undergone a THA. Patient characteristics were collected from the electronic medical record including age, gender, body mass index, Charleston comorbidity index, smoking status, and primary diagnosis. Mortality was determined through a combination of electronic chart reviews, patient phone calls, and online obituary searches. Univariate analysis was performed to identify a survival difference between the two cohorts. Multivariable Cox-Regression analyses were used to determine whether the type of operation was independently associated with mortality. Results. The mean follow up for consecutive patients was 7 years (up to 11 years) in the HRA group and 8 years (up to 16 years) in the THA group. A total of 467 HRA patients (92%) and 105 THA patients (85%) were followed for a minimum of 5-years. 92% of the THA procedures were performed prior to the availability of HRA. There were 8 mortalities (1.6%) in the HRA cohort and 11 (8.9%) in the THA cohort, a statistically significant difference (p<0.001) on univariate analysis. Low mortality rates produced underpowered multivariate models. Conclusion. We have demonstrated that patients under age 55 who undergo HRA have a significantly lower mortality rate than those undergoing THA at mid-term follow-up. This is consistent with previously published large database studies. Such studies typically analyze large heterogeneous populations of patients and surgeons. Our study uniquely examined only patients age 55 or younger from a single high-volume surgeon, and we primarily reviewed THA performed prior to the availability of HRA as a surgical option. Thus, surgeon selection bias was largely eliminated. To our knowledge, this is the first single surgeon study comparing HRA and THA in terms of mortality

Aims. The first death in the UK caused by COVID-19 occurred on 5 March 2020. We aim to describe the clinical characteristics and outcomes of major trauma and orthopaedic patients admitted in the early COVID-19 era. Methods. A prospective trauma registry was reviewed at a Level 1 Major Trauma Centre. We divided patients into Group A, 40 days prior to 5 March 2020, and into Group B, 40 days after. Results. A total of 657 consecutive trauma and orthopaedic patients were identified with a mean age of 55 years (8 to 98; standard deviation (SD) 22.52) and 393 (59.8%) were males. In all, 344 (approximately 50%) of admissions were major trauma. Group A had 421 patients, decreasing to 236 patients in Group B (36%). Mechanism of injury (MOI) was commonly a fall in 351 (52.4%) patients, but road traffic accidents (RTAs) increased from 56 (13.3%) in group A to 51 (21.6%) in group B (p = 0.030). ICU admissions decreased from 26 (6.2%) in group A to 5 (2.1%) in group B. Overall, 39 patients tested positive for COVID-19 with mean age of 73 years (28 to 98; SD 17.99) and 22 (56.4%) males. Common symptoms were dyspnoea, dry cough, and pyrexia. Of these patients, 27 (69.2%) were nosocomial infections and two (5.1%) of these patients required intensive care unit (ICU) admission with 8/39 mortality (20.5%). Of the patients who died, 50% were older and had underlying comorbidities (hypertension and cardiovascular disease, dementia, arthritis). Conclusion. Trauma admissions decreased in the lockdown phase with an increased incidence of RTAs. Nosocomial infection was common in 27 (69.2%) of those with COVID-19. Symptoms and comorbidities were consistent with previous reports with noted inclusion of dementia and arthritis. The mortality rate of trauma and COVID-19 was 20.5%, mainly in octogenarians, and COVID-19 surgical mortality was 15.4%. Cite this article: Bone Joint Open 2020;1-7:330–338

To determine the number of patients with low back pain who have low serum Vitamin-D levels in our local population and the clinical efficacy of Vitamin-D supplementation on VAS and MODQ scores. This Prospective cohort study was conducted from 20th March 2016 to 19th March 2017. 600 patients were included in the study who met the inclusion criteria, i.e. patients presenting to the Out Patient Department (OPD) with low back pain for a duration of less than six months aged between 15 to 55 years. Venous blood withdrawn and serum levels of Vitamin-D measured. According to serum Vitamin-D levels, categorized as deficient, sufficient or excess. Those having deficient Vitamin-D levels (< 2 0 ng/dL) were given Vitamin-D supplementation as Oral 50,000 IU Vitamin-D3 daily for 05 days, then once weekly for 08 weeks while those having insufficient levels (20–30 ng/dL) given Oral 50,000 IU Vitamin-D3 once weekly for 08 weeks. Vitamin-D levels, Visual Analog Pain Scale (VAS) and Modified Oswestry Disability Questionnaire (MODQ) scoring done at baseline, 02, 03 and 06 months. Data analyzed using SPSS version 23. Mean age of patients included in the study 44.21 ± 11.92 years. Out of the total, 337 (56.17%) were males and 263 (43.83%) females. Out of the total, 20.67%, 26.17% and 28.83% had mild, moderate and severe Vitamin-D deficiency, respectively. Predominantly patients with severe Vitamin-D deficiency presented in winters (October – February) (17.16%) as compared to other seasons. The most pre-dominant risk factor in patients with low Vitamin-D levels was smoking (21.33%). Mean baseline Vitamin-D levels were 13.32 ± 6.10 ng/dL and after supplementation these levels improved to 37.18 ± 11.72 ng/dL. VAS score improved from a mean baseline value to 81 to 36 at 6 months (p < 0 .01). Likewise, MODQ score decreased from a baseline mean of 46 to 25 at 6 months (p < 0 .01). Vitamin D plays a crucial role in the musculoskeletal framework of the body. The deficiency is more prevalent in the youth due to sedentary lifestyle and indoor preference. Improvement in pain & functional disability with Vitamin-D supplementation. For any reader queries, please contact . virgo_r24@hotmail.com

Revision is a key negative outcome of joint replacements. The purpose of this abstract is to present revision risk curves for hip and knee replacements based on the most recently available national data sources. Having a better understanding of determinants of revision risk can help inform clinical and health care system improvements. We explored revision risk of primary joint replacement stratified by key clinical, prosthesis, and surgeon-level factors using data from three databases managed by CIHI: the Canadian Joint Replacement Registry (CJRR), the Discharge Abstract Database, and the National Ambulatory Care Reporting System. To investigate early revisions, we used Kaplan-Meier analysis stratified by demographic factors to determine the risk of revision within up to five years of primary surgery. This analysis identified the primary cohort from the CJRR from April 1, 2012 to March 31, 2017 and was limited to mandatory reporting provinces (British Columbia, Manitoba and Ontario) to ensure maximal coverage of prosthesis information. Bearing surface was obtained from the International Prosthesis Library maintained by the International Consortium of Orthopaedic Registries (ICOR) and the International Society of Arthroplasty Registers (ISAR). The total revision risk cohort contained 283,620 primary surgeries, of which 5,765 (2%) had at least one revision. For total hip arthroplasties, revision risk at the end of the follow-up period did not differ by age, by sex or across bearing surface (metal on cross-linked polyethylene [XLPE], ceramic on XLPE, ceramic on ceramic, metal on non-cross-linked polyethylene). For hemiarthroplasties in hip fracture patients, cement fixation was significantly associated with decreased revision risk. Surgeon volume had a positive effect on survivorship with cementless fixation (2.7% at one year [95% CI 2.3%, 3.1%] for high-volume vs 3.2% [2.7%, 3.7%] for low-volume). However, surgeon volume did not have an effect on survivorship with cemented fixation (2% at one year [95% CI 1.3%, 2.6%] for high-volume vs. 2% [1.4%, 2.6%] for low-volume). For total knee replacements, revision risk increased with decreasing age and male sex. For patients aged 75 and older, four-year revision risks were 1.5% (95% CI 1.3%, 1.7%) for women and 2.0% (1.7%, 2.3%) for men, but for patients under 55 years old, they were 4.3% (3.7%, 5%) for women and 5.9% (4.9%, 6.9%) for men. Additional results from the upcoming 2019 CJRR annual report, including data up to March 31, 2018, will be presented. Revisions represent a key failure of the primary replacement, they are costly to the health care system and negatively affect patients' quality of life. CJRR's coverage is currently 72%, increased coverage and follow-up time will allow increasingly comprehensive reporting on hip and knee prostheses in Canada. Future work in this area involves exploring additional prosthesis attributes for stratification of revision risk curves and calculation of hazards ratios adjusted by age and sex

Aim. Septic arthritis is a painful infection of articular joints that is typically treated by irrigation & debridement along with antibiotic therapy. There is debate amongst the medical community whether antibiotic administration should be delayed until fluid cultures have been taken to improve culture yield. However, delaying antibiotics can also have negative consequences, including joint destruction and sepsis. Therefore, the purposes of this study were to determine: 1) whether delayed antibiotic treatment affects culture yield and prognosis and 2) if the culture yield of patients treated for septic arthritis differs for hip, knee, and shoulder based on timing of antibiotic administration. Method. A retrospective analysis was conducted on 111 patients with septic arthritis of the hip, knee, or shoulder admitted from 3/2016 to 11/2018. In patients with multiple septic joints, each joint was analyzed individually (n=122). Diagnosis was determined by the treatment of irrigation & debridement and/or a positive culture. Patients without all intervention times recorded or with periprosthetic joint infection were excluded. Demographics, laboratory tests, culture results, and intervention times were obtained through chart review. Patients were grouped based on antibiotic therapy timing: >24 hours prior to arthrocentesis (Group 1), between 24 hours and 1 hour prior (Group 2), and 1 hour prior to post-arthrocentesis (Group 3). Analysis was conducted using chi-squared tests. Results. The mean age of each group were similar: Group 1 (n=38) 55.7 years, Group 2 (n=20) 57.2 years, and Group 3 (n=64) 54.8 years. No difference was observed in culture sensitivity between groups (p=0.825) with 71.1% (27/38) positive cultures in Group 1, 75% (15/20) in Group 2, and 76.6% (49/64) in Group 3. Similarly, frequency of related readmissions within 90 days (p=0.863) did not significantly vary: 26.3% (10/38) in Group 1, 20% (4/20) in Group 2, and 25% (16/64) in Group 3. Additionally, there were no significant differences in culture sensitivity in the knee (p=0.618; Groups: 87.5%, 75%, 70.6%), shoulder (p=0.517; Groups: 77.8%, 66.7%, 90%), and hip (p=0.362; Groups: 61.9%, 80%, 80%). Conclusions. Culture sensitivities and rates of readmission were similar for all patients regardless of antibiotic administration timing. These results suggest that antibiotic administration should not be delayed in septic arthritis to improve culture yield. However, the data does not suggest that early antibiotic administration will result in better clinical outcomes by lowering readmission rates. Further research is needed to better determine the clinical benefits that early administration of antibiotics may have on patient outcomes

The objective of this study was to evaluate the short term clinical and radiological results of a new short stem hip implant. In 29 consecutive patients suffering from osteoarthritis with 33 affected hip joints, the clinical and radiological results of 33 cementless hip arthroplasties using a cementless implanted short stem prosthesis type Aida and a cementless cup type Ecofit were evaluated prospectively between October 2009 and June 2015 in two hospitals. The median age of patients at time of surgery was 55 years (range, 30–71 years), 23 male and 10 female patients were included in the study. The median clinical follow up was 24 months (range, 1.5–51 months), and the median radiological follow up was 12 months (range, 1–51 months). Two patients were lost to follow up and two patients had only one immediate postoperative x- ray. The Harris Hip Score improved from a median preoperative value of 53 to a median postoperative value of 93 at follow up. Radiological analysis showed that 19 stems (58%) showed stable bony ingrowth, five cases (15%) showed stable fibrous ingrowth. Four cases need further follow up for proper evaluation of stem fixation. The short term survival of this new short stem is very promising, and achieving the goals of standard hip arthroplasty

Introduction. Appropriate femoral stem anteversion is an important factor in maintaining stability and maximizing the performance of the bearing after total hip replacement (THR). The anteversion of the native femoral neck has been shown to have a significant effect on the final anteversion of the stem, particularly with a uncemented femoral component. The aim of this study was to quantify the variation in native femoral neck anteversion in a population of patients requiring total hip replacement. Methods. Pre-operatively, 1215 patients received CT scans as part of their routine planning for THR. Within the 3D planning, each patient's native femoral neck anteversion, measured in relation to the posterior condyles of the knee, was determined. Patients were separated into eight groups based upon gender and age. Males and females were divided by those under 55 years of age, those aged 55 to 64, 65 to 74 and those 75 or older. Results. The median anteversion in males was 12.7° (−27.1°–45.5°, IQR 6.0°–19.1°), compared to female anteversion of 16.0° (− 14.0°–54.5°, IQR 9.7°– 22.4°). These gender differences were statistically significant, p < 0.0001. Femoral anteversion in young males (<55) was significantly higher than in older males (>75), p=0.002. This age-related difference approached significance in females, p = 0.06. 14% of patients had extreme anteversion (<0° or >30°). Conclusions. The Native femoral neck anteversion in patients requiring THR is widely variable, with a range of over 80°. Females have more anteverted femurs than males. Femoral anteversion in young males was significantly higher than in older males. This age-related difference approached significance in females. Having an understanding of 3D patient morphology can greatly assist in pre-operative planning of THR, as post-op stem anteversion is likely influenced by the anteversion of the native femoral neck

Aim. Soft tissue defects of the lower leg can be closed - following the reconstructive ladder - with a pediculated fasciocutaneous suralis flap, but a free flap is gold standard in most of the cases. Aim of the study was to evaluate complications, risk factors for failure and the reasonableness of this procedure. Method. 91 patients (92 flaps, 70 males, 21 females) with a mean Age of 55 years (16 to 87) were included in the study. The patients had mean four surgical procedures before the flap, the follow-up was mean 407 days. 70 patients were classified ASA I or ASA II. Results. There were many complications, mostly wound healing Problems or hematoma. Only 40% of the patients received no Revision surgery, 71% of the flaps reached healing with Maximum two revisions (22% with one, 9% with two revisions, respectively). Necrectomy and new meshgraft were main reasons for Revision. Long term complications were swelling or disturbance of sensitivity. We lost seven flaps, eight free flaps were necessary. Three amputations were performed, but only one because of the lost flap. Conclusions. All patients with lost flaps showed relevant comorbidities. 71% of the flaps healed with Maximum two revisions and the overall flap loss rate was 6%. The Advantages of this flap are short surgery time without the need of a microvascular anastomosis and a relatively simple surgical technique. The flap loss rate of 6% seems to be acceptable and, however, the flap is a good Option and an important step of the reconstructive ladder for soft tissue defect closure of the lower leg

Objectives. This study examines variations in knee arthroplasty patient reported outcome measures according to patient age. Methods. We analysed prospectively collected outcome data (OKS, Eq5D, satisfaction, and revision) on 2456 primary knee arthroplasty patients. Patients were stratified into defined age groups (< 55, 55–64, 65–74, 75–84, and ≥85 years). Oxford Knee Score and Eq5D were analysed pre-operatively, and postoperatively at 6 months and 2 years. Absolute scores and post-operative change in scores were calculated and compared between age groups. Satisfaction scores (0–100) were analysed at 6 months post-operatively. Linear, logistic and ordinal regression modelling was used to describe the association between age and outcomes, for continuous, binary and ordinal outcomes, respectively. Kaplan-Meier analysis was performed to describe revision rates at 2 years. Results. Patients aged 65–85 years demonstrated better preoperative status than those aged under 65 (OKS, p=0.03; Eq5D, p=0.048), and over 85 years (OKS, p=0.03). Postoperatively, no significant difference in OKS or Eq5D was observed between age groups. Postoperative change in score showed a linear trend for a greater post-operative change in younger patients at 6-months and 2-years (p< 0.04). Overall satisfaction score was 84.9, but patient satisfaction was significantly lower in those aged < 55 years compared to all other age groups (78.1 Vs. 84.8, p=0.031). Cumulative overall 2-year revision rate was 1.3%. Conclusion. This study demonstrates that good early outcomes, as measured by the OKS and Eq5D, can be anticipated following knee replacement regardless of the patient's age, although younger patients gain greater improvement. However, the lower satisfaction in those aged < 55 years is a concern and suggests that outcome is not fully encapsulated by the OKS and Eq5D alone. This raises the question as to whether the OKS alone is an appropriate measure of pain and function in the younger, more active population

The universal availability of CT scanners has led to lower thresholds for imaging despite significant financial costs and radiation exposure. We hypothesized that this recent trend increased the use of CT for upper limb articular fractures and led to more frequent operative management. A 5-year retrospective study (01/07/2005–30/06/2010) was performed on all adult patients with upper extremity articular fractures (AO: 1.1, 1.3, 2.1 and 2.3) admitted to a Level-1 Trauma Centre. Patients were identified from the institutions prospectively maintained AO classification database. A total of 1651 patients with 1735 upper extremity articular fractures were identified. 1131 (65%) fractures were operated on. 556 (32%) fractures had CT imaging, 429 (77%) of these had operative management. 289 (17%) patients had multiple injuries and 168 (10%) received a scan of at least 1 other body region. There was a gradual increase in CT use and operative management 1.1, 1.3 and 2.1 fractures. Operation rates for 2.3 fractures unchanged but CT imaging frequency declined. In patients younger than 55 years operative management remained stable at 71% throughout the 5-year period considering all four regions. Overall CT use was stable at 38%, however scan rates for distal radius decreased but for proximal forearm increased. The operative management of patients older than 55 years has increased significantly from 56% in 2005, to 70% in 2010. The most marked increase was observed in proximal humerus fractures. Except for 2.3 fractures, CT rates showed similar but less pronounced increases. There is no increase in CT usage and operative management in younger upper limb articular fracture patients. CT utilization is even decreasing in distal radius fractures. Older patients are less likely to get CT scanned but there is a significant increase in operative management of their upper limb articular fractures
