There is substantial concern about the state of musculoskeletal knowledge of junior doctors. There are also marked differences in the locomotor curricula of medical schools, raising the possibility that students may be selectively disadvantaged from gaining appropriate knowledge and/or attaining a musculoskeletal career path. The aims of this study were to assess the musculoskeletal knowledge of newly qualified doctors in the south of Scotland, and to compare this between the two medical schools (Glasgow and Edinburgh) that have different locomotor teaching programmes. All final year medical students, from Glasgow and Edinburgh Universities (n=158 and 221, respectively), attending the compulsory ‘Preparation for Practice’ lecture course immediately after (Glasgow) or before (Edinburgh) final exams, were assessed by the Freedman and Bernstein musculoskeletal examination, previously validated with two different pass-standards: (i) 73.1% (by orthopaedic surgeons), and (ii) 70% (by physicians). There was a significant difference (Wilcoxon two sample test; p<0.5×10. −9. ) in the marks obtained at the two institutions, the median being 59% (IQR 50–67%) and 68% (IQR 60–76%) at Glasgow and Edinburgh respectively. The pass-rates for the two institutions (Glasgow vs. Edinburgh) were markedly different, being 17.1% vs. 32.6% for the higher pass-mark, and 21.5% vs. 48% for the lower. The majority of newly qualified doctors in the south of Scotland have inadequate musculoskeletal knowledge. There is a substantial and statistically significant difference in the scores attained by students from two neighbouring medical schools (Glasgow and Edinburgh). The striking difference in the pass-rates can be best explained by differences in respective musculoskeletal courses. These explicit and comparative deficits raise substantial questions for musculoskeletal curriculum planning, teaching, assessment and quality assurance

Medical employment standards (MES) are used to identify and quantify the effects of pathology on a person's ability to carry out their duties. Any person requiring a change in their MES for longer than 28 days should have their permanent MES altered accordingly. In the Royal Air Force this is undertaken by Medical Boards. A retrospective review was performed of all personnel attending RAF Medical Boards for a change in their PMES between 15/1/12 and 31/10/13. The primary reason for downgrade was recorded using ICD-10 code. There were 1,583 PMES downgrades, approximately 800/year. This is approximately 2% of all regular RAF personnel. Musculoskeletal disease accounted for 58% of all cases (923 cases, 500/year). Other causes included medicine and general surgery (23%), mental health (10%), obstetrics and gynaecology (5%) and other causes (4%). The majority of the musculoskeletal cases were arthropathy (42%) or back pain (31%). Musculoskeletal disease is the most common cause for medical downgrade in the RAF. More data are required to ascertain the precise nature of these cases and the level of the imposed limitations. This will allow targeted use of increasingly limited resources to ensure that our personnel are as fit as possible to execute their duties

Musculoskeletal injuries are one of the leading causes for morbidity within military personnel on operations and are the leading cause for aeromedical evacuation of British military personnel from Afghanistan for Disease and Non-Battle Injury. The objective of this study was to improve our knowledge relating to these injuries.

This prospective cohort study included all British military personnel presenting with musculoskeletal injuries to primary healthcare in Camp Bastion and the rehabilitation team working in British bases forwards of Bastion, Afghanistan. Injury report forms were completed by medical officers and physiotherapists. Data was collected over two separate two week periods during the first and second half of the tour.

273 injury forms were completed in total. Most injured body parts were back (23%), knee (17%), shoulder (13%) and ankle (13%). 53% were attributed to training, 25% were due to overuse and 37% were old injuries.

Leading cause for musculoskeletal injuries sustained on operations was training, not sport. Further studies are required to clarify what training factors are attributing to injuries which will enable design and implementation of prevention strategies.

Adipose tissue is an attractive source of mesenchymal stem cells (MSCs) as it is largely dispensable and readily accessible through minimally invasive procedures such as lipoaspiration. Until recently MSCs could only be isolated in a process involving ex-vivo culture. Pericytes (CD45−, CD146+, and CD34−) and adventitial cells (CD45−, CD146−, CD34+) represent two populations of MSCs (collectively termed perivascular stem cells or PSCs) that can be prospectively purified using fluorescence activated cell sorting (FACS). We performed FACS on lipoaspirate samples from n=129 donors to determine the frequency and yield of PSCs and to establish patient and processing factors that influence yield.

The mean number of stromal vascular fraction (SVF) cells from 100ml of lipoaspirate was 37.8×106. Within the SVF, mean cell viability was 82%, with 31.6% of cells being heamatopoietic (CD45+). Adventitial cells and pericytes represented 31.6% and 7.9% of SVF cells respectively. As such, 200ml of lipoaspirate would theoretically yield 24.5 million MSCs –a sufficient number to enable point-of-care delivery for use in several orthopaedic applications. The yield and prevalence of PSCs were minimally affected by donor age, sex and BMI. Storing lipoaspirate samples for up to 72 hours prior to processing had no significant deleterious effects on MSC yield or viability.

Our study confirms that pure populations of MSC-precursors (PSCs) can be prospectively isolated from adipose tissue, in sufficient quantities to negate the necessity for culture expansion while widening possible applications to include trauma, where a time delay between extraction and implantation excludes their use.

Aims. Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections. Methods. Between January 2019 and December 2022, 106 patients with bone and joint infections were treated by five surgeons in five hospitals. Surgical debridement and calcium sulphate bead insertion was performed for local elution of antibiotics in high concentration. In all, 100 patients were available for follow-up at regular intervals. Choice of antibiotic was tailor made for each patient in consultation with microbiologist based on the organism grown on culture and the sensitivity. In majority of our cases, we used a combination of vancomycin and culture sensitive heat stable antibiotic after a thorough debridement of the site. Primary wound closure was achieved in 99 patients and a split skin graft closure was done in one patient. Mean follow-up was 20 months (12 to 30). Results. Overall, six out of 106 patients (5.6%) presented with sepsis and poorly controlled comorbid conditions, and died in the hospital within few days of index surgery. Out of the remaining 100 patients, control of infection was achieved in 95 patients (95%). Persistence of infection was noted in five (5%) patients. Out of these 95 patients that had good control of infection, four patients (4.2%) with gap nonunion needed Masquelet procedure to achieve union. Conclusion. Our multicentre experience confirmed that surgical debridement along with calcium sulphate bead insertion was effective in treating bone and joint infections without any side effects and complications.

Aims. Tibial plateau fractures are serious injuries about the knee that have the potential to affect patients’ long-term function. To our knowledge, this is the first study to use patient-reported outcomes (PROs) with a musculoskeletal focus to assess the long-term outcome, as compared to a short-term outcome baseline, of tibial plateau fractures treated using modern techniques. Methods. In total, 102 patients who sustained a displaced tibial plateau fracture and underwent operative repair by one of three orthopaedic traumatologists at a large, academic medical centre and had a minimum of five-year follow-up were identified. Breakdown of patients by Schatzker classification is as follows: two (1.9%) Schatzker I, 54 (50.9%) Schatzker II, two (1.9%) Schatzker III, 13 (12.3%) Schatzker IV, nine (8.5%) Schatzker V, and 26 (24.5%) Schatzker VI. Follow-up data obtained included: Visual Analogue Scale (VAS) or Numeric Rating Scale (NRS) pain scores, Short Musculoskeletal Functional Assessment (SMFA), and knee range of movement (ROM). Data at latest follow-up were then compared to 12-month data using a paired t-test. Results. Patient-reported functional outcomes as assessed by overall SMFA were statistically significantly improved at five years (p < 0.001) compared with one-year data from the same patients. Patients additionally reported an improvement in the Standardized Mobility Index (p < 0.001), Standardized Emotional Index (p < 0.001), as well as improvement in Standardized Bothersome Index (p = 0.003) between the first year and latest follow-up. Patient-reported pain and knee ROM were similar at five years to their one-year follow-up. In total, 15 of the patients had undergone subsequent orthopaedic surgery for their knees at the time of most recent follow-up. Of note, only one patient had undergone knee arthroplasty following plateau fixation related to post-traumatic osteoarthritis (OA). Conclusion. Knee pain following tibial plateau fracture stabilizes at one year. However, PROs continue to improve beyond one year following tibial plateau fracture, at least in a statistical sense, if not also clinically. Patients displayed statistical improvement across nearly all SMFA index scores at their minimum five-year follow-up compared with their one-year follow-up.

Aims. Using tibial shaft fracture participants from a large, multicentre randomized controlled trial, we investigated if patient and surgical factors were associated with health-related quality of life (HRQoL) at one year post-surgery. Methods. The Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT) trial examined adults with an open or closed tibial shaft fracture who were treated with either reamed or unreamed intramedullary nails. HRQoL was assessed at hospital discharge (for pre-injury level) and at 12 months post-fracture using the Short Musculoskeletal Functional Assessment (SMFA) Dysfunction, SMFA Bother, 36-Item Short Form 36 (SF-36) Physical, and SF-36 Mental Component scores. We used multiple linear regression analysis to determine if baseline and surgical factors, as well as post-intervention procedures within one year of fracture, were associated with these HRQoL outcomes. Significance was set at p < 0.01. We hypothesize that, irrespective of the four measures used, prognosis is guided by both modifiable and non-modifiable factors and that patients do not return to their pre-injury level of function, nor HRQoL. Results. For patient and surgical factors, only pre-injury quality of life and isolated fracture showed a statistical effect on all four HRQoL outcomes, while high-energy injury mechanism, smoking, and race or ethnicity, demonstrated statistical significance for three of the four HRQoL outcomes. Patients who did not require reoperation in response to infection, the need for bone grafts, and/or the need for implant exchanges had statistically superior HRQoL outcomes than those who did require intervention within one year after initial tibial fracture nailing. Conclusion. We identified several baseline patient factors, surgical factors, and post-intervention procedures within one year after intramedullary nailing of a tibial shaft fracture that may influence a patient’s HRQoL.

Aims

Acetabular fractures are associated with long-term morbidity. Our prospective cohort study sought to understand the recovery trajectory of this injury over five years.

Aims

The aim of this study was to investigate the association between fracture displacement and survivorship of the native hip joint without conversion to a total hip arthroplasty (THA), and to determine predictors for conversion to THA in patients treated nonoperatively for acetabular fractures.

Aims. The aim of this study was to compare the functional and radiological outcomes in patients with a displaced fracture of the hip who were treated with a cemented or a cementless femoral stem. Patients and Methods. A four-year follow-up of a randomized controlled study included 141 patients who underwent surgery for a displaced femoral neck fracture. Patients were randomized to receive either a cemented (n = 67) or a cementless (n = 74) stem at hemiarthroplasty (HA; n = 83) or total hip arthroplasty (THA; n = 58). Results. Early differences in functional outcome, assessed using the Harris Hip Score, the Short Musculoskeletal Functional Assessment score and EuroQol-5D, with better results in cemented group, deteriorated over time and there were no statistically significant differences at 48 months. Two (3%) patients in the cemented group and five (6.8%) in the cementless group underwent further surgery for a periprosthetic fracture. This difference was statistically significant (p = 0.4). No patient underwent further surgery for instability or infection between one and four years postoperatively. The mortality and the radiological outcomes were similar in both groups. Conclusion. Patients with a displaced femoral neck fracture treated with an arthroplasty using a cemented or cementless stem had good function and few complications up to four years postoperatively. However, due to the poor short-term functional outcomes in the cementless group, the findings do not support their routine use in the treatment of these elderly patients.

Aims

Occult (clinical) injuries represent 15% of all scaphoid fractures, posing significant challenges to the clinician. MRI has been suggested as the gold standard for diagnosis, but remains expensive, time-consuming, and is in high demand. Conventional management with immobilization and serial radiography typically results in multiple follow-up attendances to clinic, radiation exposure, and delays return to work. Suboptimal management can result in significant disability and, frequently, litigation.

Aims

Frailty greatly increases the risk of adverse outcome of trauma in older people. Frailty detection tools appear to be unsuitable for use in traumatically injured older patients. We therefore aimed to develop a method for detecting frailty in older people sustaining trauma using routinely collected clinical data.

Aims

The aim of this study was to investigate the association between additional rehabilitation at the weekend, and in-hospital mortality and complications in patients with hip fracture who underwent surgery.

Aims

The aim of this study was to perform the first population-based description of the epidemiological and health economic burden of fracture-related infection (FRI).

Aims

To investigate health-related quality of life (HRQoL) of older adults (aged ≥ 60 years) after tibial plateau fracture (TPF) compared to preinjury and population matched values, and what aspects of treatment were most important to patients.

Aims. The aims of this study were to establish whether composite fixation (rail-plate) decreases fixator time and related problems in the management of patients with infected nonunion of tibia with a segmental defect, without compromising the anatomical and functional outcomes achieved using the classical Ilizarov technique. We also wished to study the acceptability of this technique using patient-based objective criteria. Patients and Methods. Between January 2012 and January 2015, 14 consecutive patients were treated for an infected nonunion of the tibia with a gap and were included in the study. During stage one, a radical debridement of bone and soft tissue was undertaken with the introduction of an antibiotic-loaded cement spacer. At the second stage, the tibia was stabilized using a long lateral locked plate and a six-pin monorail fixator on its anteromedial surface. A corticotomy was performed at the appropriate level. During the third stage, i.e. at the end of the distraction phase, the transported fragment was aligned and fixed to the plate with two to four screws. An iliac crest autograft was added to the docking site and the fixator was removed. Functional outcome was assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. Patient-reported outcomes were assessed using the Musculoskeletal Tumor Society (MSTS) score. Results. The mean age of patients was 38.1 years (. sd. 12.7). There were 13 men and one woman. The mean size of the defect was 6.4 cm (. sd. 1.3). the mean follow-up was 33.2 months (24 to 50). The mean external fixator index was 21.2 days/cm (. sd. 1.5). The complication rate was 0.5 (7/14) per patient. According to the classification of Paley, there were five problems and two obstacles but no true complications. The ASAMI bone score was excellent in all patients. The functional ASAMI scores were excellent in eight and good in six patients. The mean MSTS composite score was 83.9% (. sd. 7.1), with an MSTS emotional acceptance score of 4.9 (. sd. 0.5; maximum possible 5). Conclusion. Composite fixation (rail-plate) decreases fixator time and the associated complications, in the treatment of patients of infected nonunion tibia with a segmental defect. It also provides good anatomical and functional results with high emotional acceptance. Cite this article: Bone Joint J 2018;100-B:1094–9

Aims

To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture.

Although the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was designed, and has been validated, as a measure of disability in patients with disorders of the upper limb, the influence of those of the lower limb on disability as measured by the DASH score has not been assessed. The aim of this study was to investigate whether it exclusively measures disability associated with injuries to the upper limb. The Short Musculoskeletal Functional Assessment, a general musculoskeletal assessment instrument, was also completed by participants. Disability was compared in 206 participants, 84 with an injury to the upper limb, 73 with injury to the lower limb and 49 controls. We found that the DASH score also measured disability in patients with injuries to the lower limb. Care must therefore be taken when attributing disability measured by the DASH score to injuries of the upper limb when problems are also present in the lower limb. Its inability to discriminate clearly between disability due to problems at these separate sites must be taken into account when using this instrument in clinical practice or research

Antimicrobial resistance (AMR) is projected to result in 10 million deaths every year globally by 2050. Without urgent action, routine orthopaedic operations could become high risk and musculoskeletal infections incurable in a “post-antibiotic era.” However, current methods of studying AMR processes including bacterial biofilm formation are 2D in nature, and therefore unable to recapitulate the 3D processes within in vivo infection. Within this study, 3D printing was applied for the first time alongside a custom-developed bioink to bioprint 3D bacterial biofilm constructs from clinically relevant species including Staphylococcus aureus (MSSA), Methicillin-resistant staphylococcus aureus (MRSA), Escherichia coli and Pseudomonas aeruginosa. Bacterial viability and biofilm formation in bioprinted constructs was excellent, with confocal laser scanning microscopy (CSLM) used to demonstrate biofilm production and maturation over 28 days. Bioprinted 3D MRSA and MSSA biofilm constructs had greater resistance to antimicrobials than corresponding two-dimensional (2D) cultures. Thicker 3D E.coli biofilms had greater resistance to tetracycline than thinner constructs over 7 days of treatment. Raman spectroscopy was also adapted in a novel approach to non-invasively diagnose 3D bioprinted biofilm constructs located within a joint replacement model. In conclusion, mature bacterial biofilm constructs were reproducibly 3D bioprinted for the first time using clinically relevant bacteria. This methodology allows the study of antimicrobial biofilm penetration in 3D, and potentially aids future antimicrobial research, replicating joint infection more closely than current 2D culture models. Furthermore, by deploying Raman spectroscopy in a novel fashion, it was possible to diagnose 3D bioprinted biofilm infections within a joint replacement model

Limited long term data exists comparing operatively and non-operatively treated Achilles tendon ruptures. A previous randomised controlled trial comparing early outcomes showed a short term advantage for surgery, but there are no long term prospective randomised comparisons. Our aim was to determine whether surgery conferred long term benefits in terms of patient reported outcomes or re-rupture. 64 patients (80%) were followed up with postal questionnaires. Patients were asked to complete the Short Musculoskeletal Function Assessment (SMFA), Achilles Tendon Total Rupture Score (ATRS) and EQ-5D questionnaires, and to report re-ruptures. 32 patients were treated non-operatively and 32 operatively; 59 completed the SMFA and 64 the ATRS and EQ-5D assessments. There was no significant difference in SMFA score (median 1.09, IQR 4.89 in the cast group versus 2.17 and 7.07 in the operative group; p=0.347), ATRS (median 96, IQR 18 versus 93 and 15; p=0.509), EQ-5D Index (median 1.0, IQR 0.163 versus 1.0 and 0.257; p=0.327) and EQ-5D Visual Analogue Score (median score 85, IQR 15 versus 85 and 24; p=0.650). There were 2 re-ruptures in the operative group and 4 in the non-operative group (p=0.067). This is the first prospective, randomised, long term report comparing operative and non-operative management. At follow up between 13–17 years after injury, patients reported good function and health related quality of life. There was no significant difference in re-rupture rate between the treatment groups
