To investigate predictors of periprosthetic fracture level (around stem (Vancouver B) or distal to stem (Vancouver C/D) in cemented polished tapered femoral stems. Retrospective cohort study of 188 patients (mean age 79 (range 30–91); 99 (53%) male) with unilateral periprosthetic femoral fractures associated with CPT stems. Medical notes were reviewed and the following recorded: patient demographics, past medical history, drug history, date of prosthesis insertion, and date of injury. Radiographs analysis included Vancouver classification, cement restrictor type, cement mantle to implant tip distance, cortical thickness, femoral diameter and DORR classification. Univariate, multivariate and ROC curve analysis was performed. Fractures occurred at mean 7.5 years following primary procedure: 152 (83%) were B fractures; and 36 (19%) C/D. On univariate analysis female gender, lower BMI, osteoporosis, NSAID use, Bisphosphonate therapy, cortical thickness, distal cement mantle length and distal cement mantle length:femoral diameter ratio were significantly associated with C level fractures (p<0.05). Distal cement mantle lengths of >19.6mm (AUC 0.688, p<0.001) were associate with C level fractures. Multivariate analysis demonstrated female gender and distal cement mantle length:femoral diameter ratio to be independent predictors of C level periprosthetic fractures. Though female sex is the largest independent predictor of periprosthetic fractures distal to a CPT femoral stem, the relationship between cortical thickness and distal cement mantle length appears significant. As fractures distal to the stem are invariably managed by ORIF, whereas fractures around the stem frequently require revision arthroplasty, this has relevance at primary surgery in osteoporotic females to reduce the need for complex revisions

The primary aim was to assess whether patients waiting 6-months or more for a total hip (THA) or knee (KA) arthroplasty had a deterioration in their health-related quality of life (HRQoL). Secondary aims were to assess change in level of frailty and the number living in a state worse than death (WTD). Eight-six patients waiting for a primary TKA or KA for more than 6-months were selected at random from waiting lists in three centres. Patient demographics, waiting time, EuroQol 5-dimension (EQ-5D) and visual analogue scores (EQ-VAS), Rockwood clinical frailty score (CFS) and SF-36 subjective change in HRQoL were recorded at the time of and for a timepoint 6-months prior to assessment. The study was powered to the EQ-5D (primary measure of HRQoL). There were 40 male and 46 female patients with a mean age of 68 (33 to 91) years; 65 patients were awaiting a THA and 21 a TKA. The mean waiting time was 372 (226 to 749) days. The EQ-5D index deteriorated by 0.222 (95%CI 0.164 to 0.280, p<0.001). The EQ-VAS also deteriorated by 10.8 (95%CI 7.5 to 14.0, p<0.001). CFS progressed from a median of 3 to 4 (p<0.001). The number of patients WTD increased from seven to 22 (p<0.001). Thirty-one(36%) patients felt their HRQoL was much worse and 28 (33%) felt it was somewhat worse. Patients waiting more than 6-months had a clinically significant deterioration in their HRQoL and demonstrated increasing level of frailty with more than a quarter living in a health state WTD

Alcohol-based cutaneous disinfectant use is well established in the surgical environment. However, during scrubbing, volatile alcohols are inspired into the pulmonary system. With the recent reduction in the national drink driving limit, even low levels of detected breath alcohol can have legal implications. This study aimed to determine the extent to which passive inhalation of alcohol-based surgical hand disinfectant affects estimated percentage blood alcohol concentration (%BAC) on breathalyser testing. Over a one week period (September 2015), 24 theatre team members (13 surgeons, 6 scrub staff and 5 anaesthetists) were prospectively recruited. The mean cohort age was 43.7 years (50% female). Participants were instructed to scrub for 90 seconds with an alcohol-based hand disinfectant comprising of the active ingredients (per 100g): propan-1-ol 30.0g, propan-2-ol 45.0g and mecetroniumetilsulphate 0.2g. Estimated %BAC was recorded immediately before and after scrubbing, and every five minutes thereafter until levels returned to 0.00%BAC. Results ≥ 0.05%BAC were deemed above the Scottish legal driving limit. All participants exceeded the 0.05%BAC threshold on immediate post scrub testing. The mean peak %BAC was 0.12% (± 0.05) with a maximum BAC documented at ≥0.20% in four subjects. In all participants, the %BAC descended to zero over a period ranging from 10–30 minutes with a mean time to zero of 16.7 (± 4.8) minutes. Following the use of alcohol-based surgical hand disinfectant, estimated blood alcohol concentrations detected on breath sampling can rise up to four times the Scottish driving limit which may have legal and professional ramifications

We investigated whether patients who underwent internal fixation for an isolated acetabular fracture were able to return to their previous sporting activities. We studied 52 consecutive patients with an isolated acetabular fracture who were operated on between January 2001 and December 2002. Their demographic details, fracture type, rehabilitation regime, outcome and complications were documented prospectively as was their level and frequency of participation in sport both before and after surgery. Quality of life was measured using the EuroQol-5D health outcome tool (EQ-5D). There was a significant reduction in level of activity, frequency of participation in sport (both p < 0.001) and EQ-5D scores in patients of all age groups compared to a normal English population (p = 0.001). A total of 22 (42%) were able to return to their previous level of activities: 35 (67%) were able to take part in sport at some level. Of all the parameters analysed, the Matta radiological follow-up criteria were the single best predictor for resumption of sporting activity and frequency of participation

Background. Anterior Cruciate Ligament Reconstruction is a commonly performed orthopaedic operation. The use of a four-strand semitendinosus and gracilis hamstring graft (STG) is a well established method of reconstruction to restore knee stability. Aim. To assess the ten year subjective knee function and activity level following STG anterior cruciate ligament reconstruction. Methods. 86 patients underwent anterior cruciate reconstruction by two knee surgeons in the year 1999. 80 patients meet the inclusion criteria of STG reconstruction by a standard operative technique. Patient evaluation was by completion of a Lysholm Knee Score and Tegner Activity Level Scale at a minimum of ten years from reconstructive surgery. This was by initial postal questionnaire and subsequent telephone follow-up. Results. 80 patients underwent anterior cruciate reconstruction with average age 30.9 years +/− 8.8 (15 to 58 years). There was a 77.5% (62 patients) response at ten years to the questionnaire. The mean Lysholm Knee Score at ten years was 78.4 +/− 12.8 (39 to 90). The mean activity level had decreased from 8.3 to 5.3 at ten years according to the Tegner Activity Scale. 11 patients required medial and lateral partial menisectomies at the time of original reconstruction. This group of patients had a Lysholm Knee Score of 67.6 +/− 19.1 and Tegner Activity Scale of 3.9 at ten years following reconstruction. 17 of the 80 patients (21.25%) required re-operation because of further knee symptoms, with 4 patients requiring revision of the anterior cruciate following re-rupture. Conclusion. Anterior Cruciate Ligament Reconstruction with four-strand STG hamstring graft provides a reliable method of restoring knee function with a 5% revision rate for re-rupture at ten years. Combined partial medial and lateral menisectomy at the time of the initial reconstruction is a poor prognostic indicator for function at ten years

Lowest instrumented vertebra (LIV) selection is critical to preventing complications following posterior spinal arthrodesis (PSA) for thoracolumbar/lumbar adolescent idiopathic scoliosis (TL/L AIS), but evidence guiding LIV selection is limited. This study aimed to investigate the efficacy of PSA using novel unilateral convex segmental pedicle screw instrumentation (UCS) in correcting TL/L AIS, to identify radiographic parameters correlating with distal extension of PSA, and to develop a predictive equation for distal fusion extension using these parameters. We reviewed data (demographic, clinical, radiographic, and SRS-22 questionnaires) preoperatively to 2-years' follow-up for TL/L AIS patients treated by PSA using UCS between 2006 to 2011. 53 patients were included and divided into 2 groups: Group-1 (n=36) patients had PSA between Cobb-to-Cobb levels; Group-2 (n=17) patients required distal fusion extension. A mean curve correction of 80% was achieved. Mean postoperative LIV angle, TL/L apical vertebra translation (AVT), and trunk shift were lower than previous studies. Six preoperative radiographic parameters significantly differed between groups and correlated with distal fusion extension: thoracic curve size, thoracolumbar curve size, LIVA, AVT, lumbar flexibility index, and Cobb angle on lumbar convex bending. Regression analysis optimised an equation (incorporating the first five parameters) which is 81% accurate in predicting Cobb-to-Cobb fusion or distal extension. SRS-22 scores were similar between groups. We conclude that TL/L AIS is effectively treated by PSA using UCS, six radiographic parameters correlate with distal fusion extension, and a predictive equation incorporating these parameters reliably informs LIV selection and the need for fusion extension beyond the caudal Cobb level

Introduction

In orthopaedics, clinical outcome assessment (COA) is still mostly performed by questionnaires which suffer from subjectivity, a ceiling effect and pain dominance. Real life activity monitoring (AM) holds the promise to become the new standard in COA with small light weight and easy to use accelerometers. More and more activities can be identified by algorithms based on accelerometry. The identification of stair climbing for instance is important to assess the participation of patients in normal life after an orthopaedic procedure. In this study we validated a custom made algorithm to distinguish normal gait, ascending and descending stairs on a step by step basis.

Introduction. Activity scales are used throughout orthopaedics as a component of PROMs. Tegner Activity Scale is commonly used and is validated in various knee injuries in adults. It has a reading age of 18 years presenting an understanding problem for children. An alternative is HSS-PediFABS, but this looks at specific skills like running, cutting, pivoting rather than sporting level. Our aim was to determine if children understood TAS and whether their answers compared to how their parents scored them and determine if our suggested sporting levels were more appropriate for them. Method. We created a study form to compare levels given by children and their parent. We added our own suggested levels, with a reading age of 9, created by a discussion group of paediatric orthopaedic surgeons. Following ethics approval, a sample size was determined via power calculation. All patients over 7 and their parents presenting to the orthopaedic clinic at SCH over a 4-month period were asked to fill out the TAS, baseline questions and rank the new suggested sporting levels. Results. 51 patients and their parents were recruited, with a mean age of 13 (±0.31, 8–17). 35% female. The mean TAS score for children rating themselves was 7.04 (±0.32, 2–10) vs 6.43 (±0.37, 0–10) for parents rating the child (p=0.31). The average weekly activity time rated by children was 6.72 hours (±0.84, 0–30) vs 7.48 (±1.02, 0–36) rated by the parent (p=0.68). Our suggested levels for paediatric patients were ordered correctly by both groups (mode score). The mean new activity level for children was 4.9 (±0.24, 2–9) vs 4.81 (±0.26, 1–8) by their parent(p=0.79). The mean score difference for TAS was 1.42 vs 1.2 in the new score (p=0.38). Conclusion. Paediatric patients had difficulty understanding the TAS and there was poor agreement of activity levels between patients and parents

Introduction. Knee arthroscopy can be used for ligamentous repair, reconstruction and to reduce burden of infection. Understanding and feeling confident with knee arthroscopy is therefore a highly important skillset for the orthopaedic surgeon. However, with limited training or experience, furthered by reduced practical education due to COVID-19, this skill can be under-developed amongst trainee surgeons. Methods. At a single institution, ten junior doctors (FY1 to CT2), were recruited as a part of a five, two-hour session, training programme utilising the Simbionix® ARTHRO Mentor knee arthroscopy simulator, supplemented alongside educational guidance with a consultant orthopaedic knee surgeon. All students had minimal to no levels of prior arthroscopic experience. Exercises completed included maintaining steadiness, image centring and orientation, probe triangulation, arthroscopic knee examination, removal of loose bodies and meniscectomy. Pre and post experience questionnaires and quantitative repeat analysis on simulation exercises were undertaken to identify levels of improvement. Results. Comparing pre and post experience questionnaires significant improvements in levels of confidence were noted in the following domains: naming arthroscopic instruments, port positioning and insertion, recognising normal anatomy arthroscopically, holding and using arthroscopic instruments and assisting in a live theatre setting (p<0.05). Significant improvements were also noted in time taken to complete and distance covered in metres, of the simulated exercises on repeat performance (p<0.05). Conclusion. Overall, with only five sessions under senior guidance, using a simulator such as the ARTHRO Mentor, significant improvements in both levels of confidence and skill can be developed even among individuals with no prior experience

The aims were to assess whether vitamin D deficiency influenced mortality risk for patients presenting with a hip fracture. A retrospective study was undertaken including all patients aged over 50 years that were admitted with a hip fracture to a single centre during a 24-month period. Serum vitamin D levels were assessed. Patient demographics and perioperative variables and mortality were collected. Cox regression analysis (adjusting for confounding) was utilised to determine the independent association between serum vitamin D level and patient mortality. The cohort consisted of 2075 patients with a mean age of 80.7 years and 1471 (70.9%) were female. 1510 (72.8%) patients had a serum vitamin D level taken, of which 876 (58.0%) were deficient (<50nmol/l). The median follow up was 417 (IQR 242 to 651) days. During follow up there were 464 (30.7%) deaths. Survival at 1 year was significantly (p = 0.003) lower for patients who were vitamin D deficient (71.7%, 95% confidence intervals (CI) 68.6 to 74.9) compared to those who were not (79.0%, 95% CI 75.9 to 82.3). Vitamin D deficiency was also independently associated with an increased mortality risk at 2-years (HR 1.42, 95% CI 1.17 to 1.71, p = 0.03), but not at 1-year (p = 0.08). Hip fracture patients with vitamin D deficiency had an increased mortality risk. This risk was independent of confounders at 2 years. The role of measuring vitamin D levels in these patients is unclear. Improved public health policy about vitamin D may be required to reduce deficiency in this patient population

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. Methods. We undertook a retrospective, case-control study of 67 patients at mean 3.5 years (SD 1.3; 1.3 to 6.1) after TPF (47 patients underwent fixation, and 20 nonoperative management). Patients completed EuroQol five-dimension three-level (EQ-5D-3L) questionnaire, Lower Limb Function Scale (LEFS), and Oxford Knee Scores (OKS) for current and recalled prefracture status. Propensity score matching for age, sex, and deprivation in a 1:5 ratio was performed using patient level data from the Health Survey for England to obtain a control group for HRQoL comparison. The primary outcome was the difference in actual (TPF cohort) and expected (matched control) EQ-5D-3L score after TPF. Results. TPF patients had a significantly worse EQ-5D-3L utility (mean difference (MD) 0.09, 95% confidence interval (CI) 0.00 to 0.16; p < 0.001) following their injury compared to matched controls, and had a significant deterioration (MD 0.140, 95% CI 0 to 0.309; p < 0.001) relative to their preoperative status. TPF patients had significantly greater pre-fracture EQ-5D-3L scores compared to controls (p = 0.003), specifically in mobility and pain/discomfort domains. A decline in EQ-5D-3L greater than the minimal important change of 0.105 was present in 36/67 TPF patients (53.7%). Following TPF, OKS (MD -7; interquartile range (IQR) -1 to -15) and LEFS (MD -10; IQR -2 to -26) declined significantly (p < 0.001) from pre-fracture levels. Of the 12 elements of fracture care assessed, the most important to patients were getting back to their own home, having a stable knee, and returning to normal function. Conclusion. TPFs in older adults were associated with a clinically significant deterioration in HRQoL compared to preinjury level and age, sex, and deprivation matched controls for both undisplaced fractures managed nonoperatively and displaced or unstable fractures managed with internal fixation.

Introduction. To evaluate career length after surgical treatment of combined ACL + medial collateral ligament (MCL) and ACL +posterolateral corner (PLC) surgeries in all elite athletes. Secondly, in a subgroup of male professional footballers to determine career length and competition level after ACL+MCL or ACL+PLC reconstructions and compare this to a cohort who underwent isolated ACL reconstruction (ACL-R) alone. Methods. A consecutive cohort of elite athletes undergoing combined ACL+MCL surgery and combined ACL+PLC surgery between February 2001 and October 2019 were analysed. A subgroup of male footballers from this population was compared to a previously identified cohort of male, professional footballers having had primary ACL reconstruction without other ligament surgery. A minimum 2-years follow-up was required. Outcome measures were career length and competition level. Results. Ninety-eight elite athletes were included, 50 had ACL+PLC and 48 had ACL+MCL surgeries. The timeline for return to play (RTP)was significantly longer for ACL+PLC injuries (12.8 months) as compared to ACL+MCL injuries (11.1 months, p=.019). On average, career length after surgery of an athlete in the ACL+PLC group was 4.8 years and for the ACL+MCL group 4.2 years (n.s.). In the subgroup analysis of footballers, a significantly lower number of players with combined ACL+PLC surgery were able to RTP (88%, p=.003) compared to 100%for ACL+MCL surgery and 97% for isolated ACL reconstruction, as well as requiring almost 3 months longer RTP timeline (12.9±4.2 months= .002) when compared to isolated ACL (10.2 ± 3.9 months) and combined ACL+MCL groups (10.0+2.4 months). However, career length and competition level were not significantly different between groups. Conclusion. The addition of MCL surgery to ACL-R did not affect RTP time and rate in elite athletes, nor competition level in male professional footballers compared to ACL-R alone. Moreover, the career length after successful RTP following combined ACL+MCL or ACL+PLC surgeries were the same. However, professional footballers with combined ACL+PLC surgery return at a lower rate and require a longer RTP time when compared to the ones with isolated ACL-R or combined ACL+MCL surgery. For the factors assessed in this study additional MCL surgery to ACL-R alone did not alter outcome from that with ACL-R in professional soccer players

Introduction. To determine if elite athletes can return to professional sport after MCL or posterolateral (PLC) reconstruction using LARS ligaments. The secondary aims are to demonstrate the safety and efficacy of LARS by reporting sport longevity, subsequent surgeries, and complications. Methods. A retrospective review of all extra-articular knee ligament reconstructions, utilising a LARS synthetic ligament, by 3 sports knee surgeons between 2013 and 2020 was undertaken. All elite athletes aged over 16 years and a minimum of 2 years post reconstruction were included. No LARS were used for ACL reconstructions, and they were excluded if a LARS ligament was used for a PCL reconstruction. Return to play (RTP) was defined as competing at professional level or national/ international level in amateur sport. Results. Sixty-four (84.2%) MCL reconstructions and 12 (15.8%) PLC reconstructions were included. 52 (68.4%) underwent concomitant autograft cruciate(s) reconstruction including 6 (7.8%) bicruciate reconstructions. The mean age was 25.1 years (SD +/− 4.50). 35 (46.1%) were footballers and 35 (46.1%) were rugby players. Sixty-seven athletes (88.2%) returned to elite sport, 7 (9.2%) did not RTP and RTP status was unknown for 2 (2.6%) (Figure 1). 65 out of 67 (97.0%) RTP at the same/higher Tegner level. 56 (83.6%) and 20 (57.1%) were still playing at 2- and 5-years post-surgery Six (7.9%) players required further surgery due to irritation from the metal fixation implants. One had an inflammation adjacent to the synthetic material at the femoral end and the other cases involved the tibial staples. All six cases were able to RTP. One athlete, following bicruciate /MCL surgery had the LARS removed due to laxity. There was one MCL re-rupture, sustained while jumping, 4 years after returning to football. Conclusions. Utilising LARS in extra-articular knee ligament reconstructions allows 88.2% of athletes with a variety of knee ligament injuries to return to elite sport. The results compare well regarding RTP, complication, and revision rates with the published evidence for other types of MCL and PLC grafts. This, coupled with 57% of athletes still playing 5 years post-surgery suggests the LARS is safe and effective in these cases. For any figures or tables, please contact authors directly

Introduction. Anterior cruciate ligament reconstruction (ACLr) is the most widely published operation in the orthopaedic literature. Over recent years there has been increased interest in the surgical technique and role of concomitant procedures performed during ACLr. The National Ligament Registry (NLR) collects robust data on ACLr performed in the UK. In this registry analysis we explore trends in ACLr surgery and how they relate to published literature and the growing industry portfolio available to surgeons. Methods. Using data from the NLR, 14,352 ACLr performed between 2013–2021 were analysed. High impact papers on ACLr were then cross referenced against this data to see if surgical practice was influenced by literature or whether surgical practice dictated publication. Common trends were also compared to key surgical industry portfolios (Arthrex, Smith and Nephew) to see how new technology influenced surgical practice. Results. The number of ACLr performed in isolation is decreasing. The number of ACL reconstructions involving meniscal surgery shows an increasing trend since 2013, with 57% of ACLr in 2021 now involving meniscus surgery. The number of ACLr with lateral extra-articular tenodesis (LET) has increased sharply since 2018, preceding the stability trial publication in 2020. Graft preference and size has remained static despite the introduction of new graft harvest and fixation devices. Additional procedures such as other ligament reconstruction and additional cartilage surgery have also remained static over time. Conclusion. In this analysis we looked at surgical trends in ACLr and their relation to literature and industry. Meniscal intervention is increasing, in keeping with the growing level of literature in this area. In the setting of LET, a high impact level 1 study appears to have significantly changed the practice of UK surgeons with a sharp increase in the number of LET procedures being performed. Industry appears to have little influence on the change in surgical trends, suggesting high quality evidence is what drives innovation in ACLr while industry supports rather than influences innovation. It will be interesting to see the impact of the stability 2 study, recent work on the medial structures of the knee and the commissioning of cartilage centres on future trends

Introduction. Over the past 30 years multiple wars and embargos have reduced healthcare resources, infrastructure, and staff in Iraq. Subsequently, there are a lack of physiotherapists to provide rehabilitation after an anterior cruciate ligament reconstruction (ACLR). The implementation of home-based rehabilitation programmes may provide a potential solution to this problem. This study, set in in the Kurdistan region of Iraq, describes the epidemiology and outcomes of anterior cruciate ligament reconstruction (ACLR) followed by home-based rehabilitation alone. Methods. A cohort observational study of patients aged ≥ 16 years with an ACL rupture who underwent an ACLR under a single surgeon. This was performed arthroscopically using a hamstring autograft (2 portal technique). Patients completed a home-based rehabilitation programme of appropriate simplicity for the home setting. The programme consisted of stretching, range of motion and strengthening exercises based on criterion rehabilitation progressions. A full description of the programme is provided at: . https://ngmvcharity.co.uk/. . Demographics, mechanisms of injury, operative findings, and outcome data (Lysholm, Tegner Activity Scale (TAS), and revision rates) were collected from 2016 to 2021. Data were analysed using descriptive statistics. Results. The cohort consisted of 545 patients (547 knees), 99.6% were male with a mean age of 27.8 years (SD 6.18 years). The mean time from diagnosis to surgery was 40.6 months (SD 40.3). Despite data attrition Lysholm scores improved over the 15-month follow-up period, matched data showed the most improvement occurred within the first 2 months post-operatively. A peak score of 90 was observed at nine months. Post-operative TAS results showed an improvement in level of function but did not reach pre-injury levels by the final follow-up. At final follow-up, six (1.1%) patients required an ACLR revision. Conclusion. Patients who completed a home-based rehabilitation programme in Kurdistan had low revision rates and improved Lysholm scores 15 months post-operatively. To optimise resources, further research should investigate the efficacy of home-based rehabilitation for trauma and elective surgery in low- to middle-income countries and the developed world

Aims. The aims of this study were to report the outcomes of patients with a complex fracture of the lower limb in the five years after they took part in the Wound Healing in Surgery for Trauma (WHIST) trial. Methods. The WHIST trial compared negative pressure wound therapy (NPWT) dressings with standard dressings applied at the end of the first operation for patients undergoing internal fixation of a complex fracture of the lower limb. Complex fractures included periarticular fractures and open fractures when the wound could be closed primarily at the end of the first debridement. A total of 1,548 patients aged ≥ 16 years completed the initial follow-up, six months after injury. In this study we report the pre-planned analysis of outcome data up to five years. Patients reported their Disability Rating Index (DRI) (0 to 100, in which 100 = total disability), and health-related quality of life, chronic pain scores and neuropathic pain scores annually, using a self-reported questionnaire. Complications, including further surgery related to the fracture, were also recorded. Results. A total of 1,015 of the original patients (66%) provided at least one set of outcome data during the five years of follow-up. There was no evidence of a difference in patient-reported disability between the two groups at five years (NPWT group mean DRI 30.0 (SD 26.5), standard dressing group mean DRI 31.5 (SD 28.8), adjusted difference -0.86 (95% CI -4.14 to 2.40; p = 0.609). There was also no evidence of a difference in the complication rates at this time. Conclusion. We found no evidence of a difference in disability ratings between NPWT compared with standard wound dressings in the five years following the surgical treatment of a complex fracture of the lower limb. Patients in both groups reported high levels of persistent disability and reduced quality of life, with little evidence of improvement during this time.

Aims. To report the outcomes of patients with a fracture of the distal tibia who were treated with intramedullary nail versus locking plate in the five years after participating in the Fixation of Distal Tibia fracture (FixDT) trial. Methods. The FixDT trial reported the results for 321 patients randomized to nail or locking plate fixation in the first 12 months after their injury. In this follow-up study, we report the results of 170 of the original participants who agreed to be followed up until five years. Participants reported their Disability Rating Index (DRI) and health-related quality of life (EuroQol five-dimension three-level questionnaire) annually by self-reported questionnaire. Further surgical interventions related to the fracture were also recorded. Results. There was no evidence of a difference in patient-reported disability, health-related quality of life, or the need for further surgery between participants treated with either type of fixation at five years. Considering the combined results for all participants, there was no significant change in DRI scores after the first 12 months of follow-up (difference between 12 and 24 months, 3.3 (95% confidence interval -1.8 to 8.5); p = 0.203), with patients reporting around 20% disability at five years. Conclusion. This study shows that the moderate levels of disability and reduced quality of life reported by participants 12 months after a fracture of the distal tibia persist in the medium term, with little evidence of improvement after the first year.

Aims. The aims of this study, using a porcine model of multiple trauma, were to investigate the expression of microRNAs at the fracture site, in the fracture haematoma (fxH) and in the fractured bone, compared with a remote unfractured long bone, to characterize the patterns of expression of circulating microRNAs in plasma, and identify and validate messenger RNA (mRNA) targets of the microRNAs. Methods. Two multiple trauma treatment strategies were compared: early total care (ETC) and damage control orthopaedics (DCO). For this study, fxH, fractured bone, unfractured control bone, plasma, lung, and liver samples were harvested. MicroRNAs were analyzed using quantitative real-time polymerase chain reaction arrays, and the identified mRNA targets were validated in vivo in the bone, fxH, lung, and liver tissue. Results. MicroRNA expression was associated with the trauma treatment strategy and differed depending on the type of sample. In the ETC group, a more advanced fracture healing response, as reflected by the expression of osteogenic microRNAs, was seen compared with the DCO group. DCO treatment resulted in a more balanced immune response in the systemic circulation as represented by significant upregulations of several anti-inflammatory microRNAs. The in vivo validation of the abundance of putative mRNA targets reflected the levels of microRNAs which were identified. Conclusion. Local and systemic microRNA patterns of expression were identified, specific for the treatment strategy in multiple trauma, which corresponded with the expression of mRNA at the fracture site and in target organs. These findings match clinical observations and offer insights into the cellular communication which may underlie the effects of using different surgical strategies in patients with multiple trauma, both locally and systemically. We also identified a systemic involvement of microRNAs in multiple trauma which may include distant cellular communication between injured tissues. Further research may further describe the temporospatial role of circulating microRNAs after multiple trauma, their potential role in communication between organs, and prospective therapeutic applications.

Aims. This is a multicentre, prospective assessment of a proportion of the overall orthopaedic trauma caseload of the UK. It investigates theatre capacity, cancellations, and time to surgery in a group of hospitals that is representative of the wider population. It identifies barriers to effective practice and will inform system improvements. Methods. Data capture was by collaborative approach. Patients undergoing procedures from 22 August 2022 and operated on before 31 October 2022 were included. Arm one captured weekly caseload and theatre capacity. Arm two concerned patient and injury demographics, and time to surgery for specific injury groups. Results. Data was available from 90 hospitals across 86 data access groups (70 in England, two in Wales, ten in Scotland, and four in Northern Ireland). After exclusions, 709 weeks' of data on theatre capacity and 23,138 operations were analyzed. The average number of cases per operating session was 1.73. Only 5.8% of all theatre sessions were dedicated day surgery sessions, despite 29% of general trauma patients being eligible for such pathways. In addition, 12.3% of patients experienced at least one cancellation. Delays to surgery were longest in Northern Ireland and shortest in England and Scotland. There was marked variance across all fracture types. Open fractures and fragility hip fractures, influenced by guidelines and performance renumeration, had short waits, and varied least. In all, nine hospitals had 40 or more patients waiting for surgery every week, while seven had less than five. Conclusion. There is great variability in operative demand and list provision seen in this study of 90 UK hospitals. There is marked variation in nearly all injuries apart from those associated with performance monitoring. There is no evidence of local network level coordination of care for orthopaedic trauma patients. Day case operating and pathways of care are underused and are an important area for service improvement. Cite this article: Bone Jt Open 2023;4(6):463–471

Aims. National hip fracture registries audit similar aspects of care but there is variation in the actual data collected; these differences restrict international comparison, benchmarking, and research. The Fragility Fracture Network (FFN) published a revised minimum common dataset (MCD) in 2022 to improve consistency and interoperability. Our aim was to assess compatibility of existing registries with the MCD. Methods. We compared 17 hip fracture registries covering 20 countries (Argentina; Australia and New Zealand; China; Denmark; England, Wales, and Northern Ireland; Germany; Holland; Ireland; Japan; Mexico; Norway; Pakistan; the Philippines; Scotland; South Korea; Spain; and Sweden), setting each of these against the 20 core and 12 optional fields of the MCD. Results. The highest MCD adherence was demonstrated by the most recently established registries. The first-generation registries in Scandinavia collect data for 60% of MCD fields, second-generation registries (UK, other European, and Australia and New Zealand) collect for 75%, and third-generation registries collect data for 85% of MCD fields. Five of the 20 core fields were collected by all 17 registries (age; sex; surgery date/time of operation; surgery type; and death during acute admission). Two fields were collected by most (16/17; 94%) registries (date/time of presentation and American Society of Anesthesiologists grade), and five more by the majority (15/17; 88%) registries (type, side, and pathological nature of fracture; anaesthetic modality; and discharge destination). Three core fields were each collected by only 11/17 (65%) registries: prefracture mobility/activities of daily living; cognition on admission; and bone protection medication prescription. Conclusion. There is moderate but improving compatibility between existing registries and the FFN MCD, and its introduction in 2022 was associated with an improved level of adherence among the most recently established programmes. Greater interoperability could be facilitated by improving consistency of data collection relating to prefracture function, cognition, bone protection, and follow-up duration, and this could improve international collaborative benchmarking, research, and quality improvement.
