Rehabilitation for ankle fractures in adults.

BACKGROUND: Ankle fracture is one of the most common lower limb fractures. Whilst immobilisation of the ankle can support and protect the fracture site during early healing, this also increases the risk of ankle weakness, stiffness, and residual pain. Rehabilitation aims to address the after-effects of this injury, to improve ankle function and quality of life. Approaches are wide-ranging and include strategies to improve ankle joint movement, muscle strength, or both. This is an update of a Cochrane review last published in 2012. OBJECTIVES: To assess the effects of rehabilitation interventions following surgical or non-surgical management of ankle fractures in adults. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, three other databases, and two clinical trials registers in May 2022, and conducted additional searches of CENTRAL, MEDLINE, and Embase in March 2023. We also searched reference lists of included studies and relevant systematic reviews. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs comparing any rehabilitation intervention delivered to adults with ankle fracture. Interventions could have been given during or after the initial fracture management period (typically the first six weeks after injury), which may or may not have included surgical fixation. We excluded participants with multi-trauma, pathological fracture, or with established complications secondary to ankle fracture. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We collected data for five outcomes: activity limitation (ankle function), health-related quality of life (HRQoL), participant satisfaction with treatment, pain, and adverse events (we focused on re-operation, defined as unplanned return to theatre). We report the findings up to six months after injury. MAIN RESULTS: We included 53 studies (45 RCTs, 8 quasi-RCTs) with 4489 adults with ankle fracture. In most studies, orthopaedic management included surgical fixation but was non-surgical in five studies, and either surgical or non-surgical in six studies. Here, we summarise the findings for three common rehabilitation comparisons; these included the most data and were the most clinically relevant. Because of different intervention approaches, we sometimes included a study in more than one comparison. Data for other less common comparisons were also available but often included few participants and were imprecise. All studies were unavoidably at high risk of performance and detection bias. We downgraded the certainty of all evidence for this reason. We also downgraded for imprecision and when we noted inconsistencies between studies that precluded meta-analysis of data. Early (within 3 weeks of surgery) versus delayed weight-bearing (12 studies, 1403 participants) Early weight-bearing probably leads to better ankle function (mean difference (MD) 3.56, 95% confidence interval (CI) 1.35 to 5.78; 5 studies, 890 participants; moderate-certainty evidence); however, this does not include a clinically meaningful difference. Early weight-bearing may offer little or no difference to HRQoL compared to delayed weight-bearing (standardised mean difference (SMD) 0.15, 95% CI -0.01 to 0.30; 5 studies, 739 participants; low-certainty evidence); when translated to the EQ-5D scale (a commonly-used HRQoL questionnaire), any small difference was not clinically important. We were unsure whether there were any differences in participant satisfaction or pain because these outcomes had very low-certainty evidence. For adverse events, there may be little or no difference in re-operation (risk ratio (RR) 0.50, 95% CI 0.09 to 2.68; 7 studies, 1007 participants; low-certainty evidence). Removable versus non-removable ankle support (25 studies, 2206 participants) Following surgery, using a removable ankle support may lead to better ankle function (MD 6.39, 95% CI 1.69 to 11.09; 6 studies, 677 participants; low-certainty evidence). This effect included both a clinically important and unimportant difference. There is probably an improvement in HRQoL with a removable ankle support, although this difference included both a clinically important and unimportant difference when translated to the EQ-5D scale (SMD 0.30, 95% CI 0.11 to 0.50; 3 studies, 477 participants; moderate-certainty evidence). No studies reported participant satisfaction. We were unsure of the effects on pain because of very low-certainty evidence (1 study, 29 participants). There may be little or no difference in re-operations (RR 1.20, 95% CI 0.39 to 3.71; 6 studies, 624 participants; low-certainty evidence). Following non-surgical management, there may be little or no difference between removable and non-removable ankle supports in ankle function (MD 1.08, 95% CI -3.18 to 5.34; 3 studies, 399 participants), and HRQoL (SMD -0.04, 95% CI -0.24 to 0.15; 3 studies, 397 participants); low-certainty evidence. No studies reported participant satisfaction. We were unsure of the effects on pain (2 studies, 167 participants), or re-operation because of very low-certainty evidence (1 study, 305 participants). Physical therapy interventions versus usual care or other physical therapy interventions (9 studies, 857 participants) Types of interventions included the use of active controlled motion, a spring-loaded ankle trainer, an antigravity treadmill, and variations of enhanced physiotherapy (e.g. additional stretching, joint mobilisation, neuromuscular exercises), delivered during or after the initial fracture management period. We were unable to pool data because of the differences in the design of interventions and their usual care comparators. Studies often included very few participants. The certainty of the evidence for all outcomes in this comparison was very low, and therefore we were unsure of the effectiveness of these therapies. No studies in this comparison reported re-operation. AUTHORS' CONCLUSIONS: Early weight-bearing may improve outcomes in the first six months after surgery for ankle fracture, but the difference is likely to be small and may not always be clinically important. A removable ankle support may also provide a better outcome, but again, the difference may not always be clinically important. It is likely that neither approach increases the re-operation risk. We assume that the findings for these comparisons are applicable to people with closed ankle fractures, and that satisfactory fracture stabilisation had been achieved with surgery. For people who have non-surgical treatment, there is no evidence that either a removable or non-removable ankle support may be superior. We were uncertain whether any physical therapy interventions were more effective than usual care or other physical therapy interventions. We encourage investigators of future studies on rehabilitation interventions for ankle fracture to use a core outcome set.

Exploring the burden, prevalence and associated factors of chronic musculoskeletal pain in migrants from North Africa and Middle East living in Europe: a scoping review.

BACKGROUND: Immigrants are exposed to numerous risk factors that may contribute to the development of chronic musculoskeletal pain. Recent political and environmental crises in North Africa and the Middle East have led to an increase in immigration to Europe that has challenged the healthcare system and especially the management of chronic conditions. OBJECTIVE: The aims of this scoping review are to investigate the burden, prevalence, and associated factors of chronic musculoskeletal pain in immigrants from North Africa and the Middle East in Europe during the last decade. The intentions of the review are to inform healthcare policymakers, to identify gaps in the literature, and aid the planning of future research. DESIGN: Online databases Medline, Embase, PubMed and Web of Science were used to identify epidemiological studies published from2012-2022 examining chronic pain in populations from North Africa and the Middle East with a migration background residing in Europe. RESULTS: In total eleven studies were identified conducted in Norway (n = 3), Denmark (n = 3), Germany (n = 1), Austria (n = 1), Sweden (n = 1), and Switzerland (n = 1). Among the identified studies, eight studies were cross-sectional (n = 8), two were prospective cohort studies (n = 2) and one was a retrospective cohort study (n = 1). Data suggested that chronic pain is more prevalent, more widespread, and more severe in people with than without a migration background. Furthermore, immigrants who have resided in the destination country for a longer period experience a higher prevalence of chronic pain compared to those in the early phases of migration. The following factors were found to be associated with chronic pain in this population: female gender, lower education, financial hardship, being underweight or obese, time in transit during migration, experience of trauma, immigration status, anxiety, depression, and post-traumatic stress disorder. CONCLUSION: Several gaps in the literature were identified. Research is limited in terms of quantity and quality, does not reflect actual immigration trends, and does not account for immigration factors. Prospective cohort studies with long follow-ups would aid in improving prevention and management of chronic pain in populations with a migration background. In particular, they should reflect actual immigration trajectories, account for immigration factors, and have valid comparison groups in the countries of origin, transit and destination.

Barrier-Forming Potential of Epithelial Cells from the Exstrophic Bladder.

Bladder exstrophy (BEX) is a rare developmental abnormality resulting in an open, exposed bladder plate. Although normal bladder urothelium is a mitotically quiescent barrier epithelium, histologic studies of BEX epithelia report squamous and proliferative changes that can persist beyond surgical closure. The current study examined whether patient-derived BEX epithelial cells in vitro were capable of generating a barrier-forming epithelium under permissive conditions. Epithelial cells isolated from 11 BEX samples, classified histologically as transitional (n = 6) or squamous (n = 5), were propagated in vitro. In conditions conducive to differentiated tight barrier formation by normal human urothelial cell cultures, 8 of 11 BEX lines developed transepithelial electrical resistances of more than 1000 Ω.cm2, with 3 squamous lines failing to generate tight barriers. An inverse relationship was found between expression of squamous KRT14 transcript and barrier development. Transcriptional drivers of urothelial differentiation PPARG, GATA3, and FOXA1 showed reduced expression in squamous BEX cultures. These findings implicate developmental interruption of urothelial transcriptional programming in the spectrum of transitional to squamous epithelial phenotypes found in BEX. Assessment of BEX epithelial phenotype may inform management and treatment strategies, for which distinction between reversible versus intractably squamous epithelium could identify patients at risk of medical complications or those who are most appropriate for reconstructive tissue engineering strategies.

Lower limb muscle strength and balance in older adults with a distal radius fracture: a systematic review.

BACKGROUND: Distal radius fractures are common fractures in older adults and associated with increased risk of future functional decline and hip fracture. Whether lower limb muscle strength and balance are impaired in this patient population is uncertain. To help inform rehabilitation requirements, this systematic review aimed to compare lower limb muscle strength and balance between older adults with a distal radius fracture with matched controls, and to synthesise lower limb muscle strength and balance outcomes in older adults with a distal radius fracture. METHODS: We searched Embase, MEDLINE, and CINAHL (1990 to 25 May 2022) for randomised and non-randomised controlled clinical trials and observational studies that measured lower limb muscle strength and/or balance using instrumented measurements or validated tests, in adults aged ≥ 50 years enrolled within one year after distal radius fracture. We appraised included observational studies using a modified Newcastle-Ottawa Scale and included randomised controlled trials using the Cochrane risk-of-bias tool. Due to the clinical and methodological heterogeneity in included studies, we synthesised results narratively in tables and text. RESULTS: Nineteen studies (10 case-control studies, five case series, and four randomised controlled trials) of variable methodological quality and including 1835 participants (96% women, mean age 55-73 years, median sample size 82) were included. Twelve included studies (63%) assessed strength using 10 different methods with knee extension strength most commonly assessed (6/12 (50%) studies). Five included case-control studies (50%) assessed lower limb strength. Cases demonstrated impaired strength during functional tests (two studies), but knee extension strength assessment findings were conflicting (three studies). Eighteen included studies (95%) assessed balance using 14 different methods. Single leg balance was most commonly assessed (6/18 (33%) studies). All case-control studies assessed balance with inconsistent findings. CONCLUSION: Compared to controls, there is some evidence that older adults with a distal radius fracture have impaired lower limb muscle strength and balance. A cautious interpretation is required due to inconsistent findings across studies and/or outcome measures. Heterogeneity in control participants' characteristics, study design, study quality, and assessment methods limited synthesis of results. Robust case-control and/or prospective observational studies are needed.

'It Makes Me Feel Old': Understanding the Experience of Recovery From Ankle Fracture at 6 Months in People Aged 50 Years and Over.

Ankle fracture is a common injury, and depending on injury severity, treatment may be a support boot, cast or surgery. Older people, particularly those with severe injuries who are asked to restrict weight bearing, struggle with early recovery. To elicit older peoples' experience of recovery 6 months after injury, we drew on a phenomenological approach using interviews. Findings revealed that getting on with life was a way of accepting what it feels like to 'be vulnerable', needing to 'be safe' while determinedly working hard to 'be myself'. Being vulnerable identified endurance of inactivity, loneliness and dependency in the non-weight bearing period of recovery, followed by a struggle to weight bear while lacking confidence and being fearful of falling and causing further damage. Being safe conveyed fragility where sensations, pain and stiffness acted as bodily reminders of injury. Lack of function and awareness of danger led to carefulness where planning or curtailing of activities ensured their safety. Being myself showed a determination to push away from a disrupted self-identify of being older or disabled while being challenged by the continuous process of learning to be more mobile. A lack of readiness for old age created a drive to age well. Despite loss of ability, participants hoped to regain their pre-injury way of living. This study challenges practice that disregards the hard work required to recover from ankle fracture. As comorbidity increases with age, failure to consider this aspect may contribute to frailty in this group of older people.

Progressive exercise compared with best practice advice, with or without corticosteroid injection, for the treatment of patients with rotator cuff disorders (GRASP): a multicentre, pragmatic, 2 × 2 factorial, randomised controlled trial.

BACKGROUND: Corticosteroid injections and physiotherapy exercise programmes are commonly used to treat rotator cuff disorders but the treatments' effectiveness is uncertain. We aimed to compare the clinical effectiveness and cost-effectiveness of a progressive exercise programme with a single session of best practice physiotherapy advice, with or without corticosteroid injection, in adults with a rotator cuff disorder. METHODS: In this pragmatic, multicentre, superiority, randomised controlled trial (2 × 2 factorial), we recruited patients from 20 UK National Health Service trusts. We included patients aged 18 years or older with a rotator cuff disorder (new episode within the past 6 months). Patients were excluded if they had a history of significant shoulder trauma (eg, dislocation, fracture, or full-thickness tear requiring surgery), neurological disease affecting the shoulder, other shoulder conditions (eg, inflammatory arthritis, frozen shoulder, or glenohumeral joint instability), received corticosteroid injection or physiotherapy for shoulder pain in the past 6 months, or were being considered for surgery. Patients were randomly assigned (centralised computer-generated system, 1:1:1:1) to progressive exercise (≤6 sessions), best practice advice (one session), corticosteroid injection then progressive exercise, or corticosteroid injection then best practice advice. The primary outcome was the Shoulder Pain and Disability Index (SPADI) score over 12 months, analysed on an intention-to-treat basis (statistical significance set at 1%). The trial was registered with the International Standard Randomised Controlled Trial Register, ISRCTN16539266, and EuDRACT, 2016-002991-28. FINDINGS: Between March 10, 2017, and May 2, 2019, we screened 2287 patients. 708 patients were randomly assigned to progressive exercise (n=174), best practice advice (n=174), corticosteroid injection then progressive exercise (n=182), or corticosteroid injection then best practice advice (n=178). Over 12 months, SPADI data were available for 166 (95%) patients in the progressive exercise group, 164 (94%) in the best practice advice group, 177 (97%) in the corticosteroid injection then progressive exercise group, and 175 (98%) in the corticosteroid injection then best practice advice group. We found no evidence of a difference in SPADI score between progressive exercise and best practice advice when analysed over 12 months (adjusted mean difference -0·66 [99% CI -4·52 to 3·20]). We also found no evidence of a difference between corticosteroid injection compared with no injection when analysed over 12 months (-1·11 [-4·47 to 2·26]). No serious adverse events were reported. INTERPRETATION: Progressive exercise was not superior to a best practice advice session with a physiotherapist in improving shoulder pain and function. Subacromial corticosteroid injection provided no long-term benefit in patients with rotator cuff disorders. FUNDING: UK National Institute for Health Research Technology Assessment Programme.

Characteristics of L-PRP preparations for treating Achilles tendon rupture within the PATH-2 study.

Platelet-rich plasma (PRP) is an autologous preparation that has been claimed to improve healing and mechanobiological properties of tendons both in vitro and in vivo. In this sub-study from the PATH-2 (PRP in Achilles Tendon Healing-2) trial, we report the cellular and growth factor content and quality of the Leukocyte-rich PRP (L-PRP) (N = 103) prepared using a standardized commercial preparation method across 19 different UK centers. Baseline whole blood cell counts (red cells, leukocyte and platelets) demonstrated that the two groups were well-matched. L-PRP analysis gave a mean platelet count of 852.6 x 109/L (SD 438.96), a mean leukocyte cell count of 15.13 x 109/L (SD 10.28) and a mean red blood cell count of 0.91 x 1012/L (SD 1.49). The activation status of the L-PRP gave either low or high expression levels of the degranulation marker CD62p before and after ex-vivo platelet activation respectively. TGF-ß, VEGF, PDGF, IGF and FGFb mean concentrations were 131.92 ng/ml, 0.98 ng/ml, 55.34 ng/ml, 78.2 ng/ml and 111.0 pg/ml respectively with expected correlations with both platelet and leukocyte counts. While PATH-2 results demonstrated that there was no evidence L-PRP is effective for improving clinical outcomes at 24 weeks after Achilles tendon rupture, our findings support that the majority of L-PRP properties were within the method specification and performance.

Exercise for people with a fragility fracture of the pelvis or lower limb: a systematic review of interventions evaluated in clinical trials and reporting quality.

BACKGROUND: To aid design of exercise trials for people with pelvic and lower limb fragility fractures a systematic review was conducted to identify what types of exercise interventions and mobility outcomes have been assessed, investigate intervention reporting quality, and evaluate risk of bias in published trials. METHODS: Systematic searches of electronic databases (CENTRAL, MEDLINE, EMBASE, PEDro) 1996-2019 were conducted to identify randomised controlled trials of exercise for pelvic or lower limb fragility fractures. Two reviewers independently screened titles and abstracts. One reviewer extracted data, a second verified. Two reviewers independently assessed risk of bias. Intervention reporting quality was based on TIDieR, assessed by one reviewer and verified by a second. Narrative synthesis was undertaken. Registration: PROSPERO CRD42017060905. RESULTS: Searches identified 37 trials including 3564 participants, median sample size 81 (IQR 48-124), participants aged 81 years (IQR 79-82) and 76% (2536/3356) female. All trials focussed on people with hip fracture except one on ankle fracture. Exercise types focussed on resistance exercise in 14 trials, weight bearing exercise in 5 trials, 13 varied dose of sessions with health professionals, and 2 trials each focussed on treadmill gait training, timing of weight bearing or aerobic exercise. 30/37 (81%) of trials reported adequate sequence generation, 25/37 (68%) sufficient allocation concealment. 10/37 (27%) trials lacked outcome assessor blinding. Of 65 exercise interventions, reporting was clear for 33 (51%) in terms of when started, 61 (94%) for where delivered, 49 (75%) for who delivered, 47 (72%) for group or individual, 29 (45%) for duration, 46 (71%) for session frequency, 8 (12%) for full prescription details to enable the exercises to be reproduced, 32 (49%) clearly reported tailoring or modification, and 23 (35%) reported exercise adherence. Subjectively assessed mobility was assessed in 22/37 (59%) studies and 29/37 (78%) used an objective measure. CONCLUSIONS: All trials focussed on hip fracture, apart from one ankle fracture trial. Research into pelvic and other lower limb fragility fractures is indicated. A range of exercise types were investigated but to date deficiencies in intervention reporting hamper reproducibility. Adoption of TIDieR and CERT guidelines should improve intervention reporting as use increases. Trials would be improved by consistent blinded outcome assessor use and with consensus on which mobility outcomes should be assessed.

Manipulation of Magnetic Dipole Emission from Eu3+ with Mie-Resonant Dielectric Metasurfaces.

Mie-resonant high-index dielectric nanoparticles and metasurfaces have been suggested as a viable platform for enhancing both electric and magnetic dipole transitions of fluorescent emitters. While the enhancement of the electric dipole transitions by such dielectric nanoparticles has been demonstrated experimentally, the case of magnetic-dipole transitions remains largely unexplored. Here, we study the enhancement of spontaneous emission of Eu3+ ions, featuring both electric and magnetic-dominated dipole transitions, by dielectric metasurfaces composed of Mie-resonant silicon nanocylinders. By coating the metasurfaces with a layer of an Eu3+ doped polymer, we observe an enhancement of the Eu3+ emission associated with the electric (at 610 nm) and magnetic-dominated (at 590 nm) dipole transitions. The enhancement factor depends systematically on the spectral proximity of the atomic transitions to the Mie resonances as well as their multipolar order, both controlled by the nanocylinder size. Importantly, the branching ratio of emission via the electric or magnetic transition channel can be modified by carefully designing the metasurface, where the magnetic dipole transition is enhanced more than the electric transition for cylinders with radii of about 130 nm. We confirm our observations by numerical simulations based on the reciprocity principle. Our results open new opportunities for bright nanoscale light sources based on magnetic transitions.

22q11.2 duplications in a UK cohort with bladder exstrophy-epispadias complex.

The bladder exstrophy-epispadias complex (BEEC) comprises of a spectrum of anterior midline defects, all affecting the lower urinary tract, the external genitalia, and the bony pelvis. In extreme cases, the gastrointestinal tract is also affected. The pathogenesis of BEEC is unclear but chromosomal aberrations have been reported. In particular, duplications of 22q11.2 have been identified in eight unrelated individuals with BEEC. The current study aimed to identify chromosomal copy number variants in BEEC. Analyses was performed using the Affymetrix Genome-wide SNP6.0 assay in 92 unrelated patients cared for by two UK pediatric urology centers. Three individuals had a 22q11.2 duplication, a significantly higher number than that found in a control group of 12,500 individuals with developmental delay who had undergone microarray testing (p < .0001). Sequencing of CRKL, implicated in renal tract malformations in DiGeorge syndrome critical region at 22q11, in 89 individuals with BEEC lacking 22q11 duplications revealed no pathogenic variants. To date, 22q11.2 duplication is the genetic variant most commonly associated with BEEC. This is consistent with the hypothesis that altered expression of a single, yet to be defined, gene therein is critical to the pathogenesis of this potentially devastating congenital disorder.

Prognostic factors for recovery following acute lateral ankle ligament sprain: a systematic review.

BACKGROUND: One-third of individuals who sustain an acute lateral ankle ligament sprain suffer significant disability due to pain, functional instability, mechanical instability or recurrent sprain after recovery plateaus at 1 to 5 years post injury. The identification of early prognostic factors associated with poor recovery may provide an opportunity for early-targeted intervention and improve outcome. METHODS: We performed a comprehensive search of AMED, EMBASE, Psych Info, CINAHL, SportDiscus, PubMed, CENTRAL, PEDro, OpenGrey, abstracts and conference proceedings from inception to September 2016. Prospective studies investigating the association between baseline prognostic factors and recovery over time were included. Two independent assessors performed the study selection, data extraction and quality assessment of the studies. A narrative synthesis is presented due to inability to meta-analyse results due to clinical and statistical heterogeneity. RESULTS: The search strategy yielded 3396 titles/abstracts after duplicates were removed. Thirty-six full text articles were then assessed, nine of which met the study inclusion criteria. Six were prospective cohorts, and three were secondary analyses of randomised controlled trials. Results are presented for nine studies that presented baseline prognostic factors for recovery after an acute ankle sprain. Age, female gender, swelling, restricted range of motion, limited weight bearing ability, pain (at the medial joint line and on weight-bearing dorsi-flexion at 4 weeks, and pain at rest at 3 months), higher injury severity rating, palpation/stress score, non-inversion mechanism injury, lower self-reported recovery, re-sprain within 3 months, MRI determined number of sprained ligaments, severity and bone bruise were found to be independent predictors of poor recovery. Age was one prognostic factor that demonstrated a consistent association with outcome in three studies, however cautious interpretation is advised. CONCLUSIONS: The associations between prognostic factors and poor recovery after an acute lateral ankle sprain are largely inconclusive. At present, there is insufficient evidence to recommend any factor as an independent predictor of outcome. There is a need for well-conducted prospective cohort studies with adequate sample size and long-term follow-up to provide robust evidence on prognostic factors of recovery following an acute lateral ankle sprain.

Close Contact Casting vs Surgery for Initial Treatment of Unstable Ankle Fractures in Older Adults: A Randomized Clinical Trial.

Importance: Ankle fractures cause substantial morbidity in older persons. Surgical fixation is the contemporary intervention but is associated with infection and other healing complications. Objective: To determine whether initial fracture treatment with close contact casting, a molded below-knee cast with minimal padding, offers outcome equivalent to that with immediate surgery, with fewer complications and less health resource use. Design, Setting, and Participants: This was a pragmatic, equivalence, randomized clinical trial with blinded outcome assessors. A pilot study commenced in May 2004, followed by multicenter recruitment from July 2010 to November 2013; follow-up was completed May 2014. Recruitment was from 24 UK major trauma centers and general hospitals. Participants were 620 adults older than 60 years with acute, overtly unstable ankle fracture. Exclusions were serious limb or concomitant disease or substantial cognitive impairment. Interventions: Participants were randomly assigned to surgery (n = 309) or casting (n = 311). Casts were applied in the operating room under general or spinal anesthesia by a trained surgeon. Main Outcomes and Measures: The primary 6-month, per-protocol outcome was the Olerud-Molander Ankle Score at 6 months (OMAS; range, 0-100; higher scores indicate better outcomes and fewer symptoms), equivalence prespecified as ±6 points. Secondary outcomes were quality of life, pain, ankle motion, mobility, complications, health resource use, and patient satisfaction. Results: Among 620 adults (mean age, 71 years; 460 [74%] women) who were randomized, 593 (96%) completed the study. Nearly all participants (579/620; 93%) received allocated treatment; 52 of 275 (19%) who initially received casting later converted to surgery, which was allowable in the casting treatment pathway to manage early loss of fracture reduction. At 6 months, casting resulted in ankle function equivalent to that with surgery (OMAS score, 66.0 [95% CI, 63.6-68.5] for surgery vs 64.5 [95% CI, 61.8-67.2] for casting; mean difference, -0.6 [95% CI, -3.9 to 2.6]; P for equivalence = .001). Infection and wound breakdown were more common with surgery (29/298 [10%] vs 4/275 [1%]; odds ratio [OR], 7.3 [95% CI, 2.6-20.2]), as were additional operating room procedures (18/298 [6%] for surgery and 3/275 [1%] for casting; OR, 5.8 [95% CI, 1.8-18.7]). Radiologic malunion was more common in the casting group (38/249 [15%] vs 8/274 [3%] for surgery; OR, 6.0 [95% CI, 2.8-12.9]). Casting required less operating room time compared with surgery (mean difference [minutes/participant], -54 [95% CI, -58 to -50]). There were no significant differences in other secondary outcomes: quality of life, pain, ankle motion, mobility, and patient satisfaction. Conclusions and Relevance: Among older adults with unstable ankle fracture, the use of close contact casting compared with surgery resulted in similar functional outcomes at 6 months. Close contact casting may be an appropriate treatment for such patients. Trial Registration: isrctn.com Identifier: ISRCTN04180738.

Antegrade venography identifies parallel venous duplications in the majority of adolescents with varicocele.

PURPOSE: We performed intraoperative antegrade venography to assess the prevalence of internal spermatic venous malformations in adolescents with varicocele. MATERIALS AND METHODS: During a 2-year period 58 adolescent males with visible or palpable varicocele underwent antegrade venography before varicocele surgery. Antegrade venography was performed through a scrotal incision. A vein within the pampiniform plexus was cannulated and up to 1.75 mg/kg iohexol 300 mg/ml was injected to outline the entire length of the internal spermatic vein. The radiographs were reviewed and classified according to Bähren and Murray criteria. RESULTS: Of the patients 43 (74.1%) demonstrated parallel duplications (Murray classification type P) of the internal spermatic vein. This rate is higher than the 2% reported based on retrograde venography. Of the patients with parallel duplications 21 (48.8%) showed duplications arising superior to the iliac crest (subtype A) and 22 (51.2%) had a combination of proximal duplications (subtypes B and C). Ten patients (17.2%) had a single internal spermatic vein, 2 (3.4%) had lumbar collaterals and 3 (5.2%) had renal collaterals. CONCLUSIONS: Parallel duplication of the internal spermatic vein is a common finding on antegrade venography. The various levels of duplication need to be identified before treatment of varicocele to maximize the success of the procedure.

Ankle Injury Management (AIM): design of a pragmatic multi-centre equivalence randomised controlled trial comparing Close Contact Casting (CCC) to Open surgical Reduction and Internal Fixation (ORIF) in the treatment of unstable ankle fractures in patients over 60 years.

BACKGROUND: Ankle fractures account for 9% of all fractures with a quarter of these occurring in adults over 60 years. The short term disability and long-term consequences of this injury can be considerable. Current opinion favours open reduction and internal fixation (ORIF) over non-operative treatment (fracture manipulation and the application of a standard moulded cast) for older people. Both techniques are associated with complications but the limited published research indicates higher complication rates of fracture malunion (poor position at healing) with casting. The aim of this study is to compare ORIF with a modification of existing casting techniques, Close Contact Casting (CCC). We propose that CCC may offer an equivalent functional outcome to ORIF and avoid the risks associated with surgery. METHODS/DESIGN: This study is a pragmatic multi-centre equivalence randomised controlled trial. 620 participants will be randomised to receive ORIF or CCC after sustaining an isolated displaced unstable ankle fracture. Participants will be recruited from a minimum of 20 National Health Service (NHS) acute hospitals throughout England and Wales. Participants will be aged over 60 years and be ambulatory prior to injury. Follow-up will be at six weeks and six months after randomisation. The primary outcome is the Olerud & Molander Ankle Score, a functional patient reported outcome measure, at 6 months. Follow-up will also include assessments of mobility, ankle range of movement, health related quality of life and complications. The six-month follow-up will be conducted face-to-face by an assessor blinded to the allocated intervention. A parallel economic evaluation will consider both a health service and a broader societal perspective including the individual and their family. In order to explore patient experience of their treatment and recovery, a purposive sample of 40 patients will also be interviewed using a semi-structured interview schedule between 6-10 weeks post treatment. DISCUSSION: This multicentre study was open to recruitment July 2010 and recruitment is due to be completed in December 2013. TRIAL REGISTRATION: Current Controlled Trials ISRCTN04180738.

The true pelvic volume change with various corrective osteotomy techniques for exstrophy-epispadias complex spectrum: the value of computer-assisted virtual surgery.

Pelvic osteotomies are essential to approximate widened symphysis pubis in the exstrophy-epispadias complex, yet it is unknown which osteotomy type has the greatest effect on pelvic volume. We therefore used virtual surgery to study pelvic volume change with anterior, oblique, and posterior iliac osteotomies. Preoperative CT scans of two cloacal and one classic bladder exstrophy patients were used. Simulations were free-hand or constrained to keep minimal strain in the sacrospinous SSL and sacrotuberous STL ligaments. Changes in inter-pubic distance, pelvic volume, SSL and STL strains were measured. Mean pelvic volume decreased by 10% with free hand compared to 23% with constrained simulations ( P  = 0.171) and decreased by 7% with posterior, 17% with diagonal and 26% with horizontal osteotomies ( P  = 0.193). SSL and STL were strained by 20% and 26%, respectively, with free-hand simulations. A statistically significant moderate positive correlation was found between the decrease in inter-pubic distance and reduction in pelvic volume (r = 0.6, P  = 0.004). Mean pelvic volume decreased 0.05, 0.37 and 0.62% for each mm of pubic symphysis approximation with posterior, diagonal and horizontal osteotomies, respectively. Differences in effect on pelvic volume were identified between the osteotomies using virtual surgery which predicted residual diastasis in actual cloacal exstrophy surgical reconstructions. Oblique osteotomies are a compromise, avoiding difficulties with posterior osteotomies and excessive pelvic volume reduction with horizontal osteotomies. Understanding how osteotomy type affects pelvic morphology with virtual surgery may be an effective adjunct to pre-operative planning in exstrophy spectrum.

Bladder Neck Surgery is not Routinely Needed to Achieve Urinary Continence in Patients with Primary Epispadias.

BACKGROUND: This study aims at investigating the continence outcome in primary epispadias patients treated at a tertiary center. The authors hypothesized that additional continence procedures following primary epispadias repair is not routinely needed. METHODS: Patients treated for primary epispadias at the authors' institution between 2007 and 2019 and toilet trained, were identified from a prospective maintained database. Males underwent chordee correction, urethroplasty and glanuloplasty. Females underwent genitoplasty with reduction urethroplasty. If continence was not achieved by 4-5 years of age, pelvic floor muscle (PFM) biofeedback therapy was performed. Other continent procedures were discussed with family/patient if still incontinent. PRIMARY OUTCOME: urinary continence. SECONDARY OUTCOMES: PFM biofeedback therapy, continence surgery, hydronephrosis. Type of epispadias, age at repair and follow-up presented as median was also reported. RESULTS: Thirty-three patients (29 males) were included. Twelve had penopubic epispadias, 13 glanular/penile, 4 duplicated urethra, 4 females. Median age at repair: 2 years (IQR 1-3), at follow-up: 8 years (IQR 6-10). Daytime continence: 100 % in penile/glanular; 33 % in penopubic and 75 % in duplicated urethra. Nighttime continence: respectively 92 %, 50 % and 100 %. 24 % of males were intermittently incontinent. All patients except one voided urethrally. One patient underwent bladder neck closure, ileocystoplasty and Mitrofanoff. One girl achieved daytime continence, 2 were intermittently incontinent, one continuously incontinent. All were enuretic. 38 % of boys and 100 % of girls had biofeedback therapy. None had hydronephrosis/renal impairment. CONCLUSIONS: Most children with primary epispadias can achieve social urinary continence spontaneously or with the support of PFM biofeedback therapy. Other continence procedures should be reserved for patients who do not attain satisfactory continence. LEVEL OF EVIDENCE: Treatment study - level IV.

Clinical consensus recommendations for the non-surgical treatment of children with Perthes' disease in the UK.

Aims: The aim of this study was to produce clinical consensus recommendations about the non-surgical treatment of children with Perthes' disease. The recommendations are intended to support clinical practice in a condition for which there is no robust evidence to guide optimal care. Methods: A two-round, modified Delphi study was conducted online. An advisory group of children's orthopaedic specialists consisting of physiotherapists, surgeons, and clinical nurse specialists designed a survey. In the first round, participants also had the opportunity to suggest new statements. The survey included statements related to 'Exercises', 'Physical activity', 'Education/information sharing', 'Input from other services', and 'Monitoring assessments'. The survey was shared with clinicians who regularly treat children with Perthes' disease in the UK using clinically relevant specialist groups and social media. A predetermined threshold of ≥ 75% for consensus was used for recommendation, with a threshold of between 70% and 75% being considered as 'points to consider'. Results: A total of 40 participants took part in the first round, of whom 31 completed the second round. A total of 87 statements were generated by the advisory group and included in the first round, at the end of which 31 achieved consensus and were removed from the survey, and an additional four statements were generated. A total of 60 statements were included in the second round and 45 achieved the threshold for consensus from both rounds, with three achieving the threshold for 'points to consider'. The recommendations predominantly included self-management, particularly relating to advice about exercise and education for children with Perthes' disease and their families. Conclusion: Children's orthopaedic specialists have reached consensus on recommendations for non-surgical treatment in Perthes' disease. These statements will support decisions made in clinical practice and act as a foundation to support clinicians in the absence of robust evidence. The dissemination of these findings and the best way of delivering this care needs careful consideration, which we will continue to explore.

Effectiveness of supervised versus self-directed rehabilitation for adults aged 50 years and over with ankle fractures: protocol for the AFTER trial.

Aims: Ankle fractures are common, mainly affecting adults aged 50 years and over. To aid recovery, some patients are referred to physiotherapy, but referral patterns vary, likely due to uncertainty about the effectiveness of this supervised rehabilitation approach. To inform clinical practice, this study will evaluate the effectiveness of supervised versus self-directed rehabilitation in improving ankle function for older adults with ankle fractures. Methods: This will be a multicentre, parallel-group, individually randomized controlled superiority trial. We aim to recruit 344 participants aged 50 years and older with an ankle fracture treated surgically or non-surgically from at least 20 NHS hospitals. Participants will be randomized 1:1 using a web-based service to supervised rehabilitation (four to six one-to-one physiotherapy sessions of tailored advice and prescribed home exercise over three months), or self-directed rehabilitation (provision of advice and exercise materials that participants will use to manage their recovery independently). The primary outcome is participant-reported ankle-related symptoms and function six months after randomization, measured by the Olerud and Molander Ankle Score. Secondary outcomes at two, four, and six months measure health-related quality of life, pain, physical function, self-efficacy, exercise adherence, complications, and resource use. Due to the nature of the interventions, participants and intervention providers will be unblinded to treatment allocation. Conclusion: This study will assess whether supervised rehabilitation is more effective than self-directed rehabilitation for adults aged 50 years and older after ankle fracture. The results will provide evidence to guide clinical practice. At the time of submission, the trial is currently completing recruitment, and follow-up will be completed in 2024.

The FAME trial study protocol: In younger adults with unstable ankle fractures treated with close contact casting, is ankle function not worse than those treated with surgical intervention?

Aims: Ankle fracture is one of the most common musculoskeletal injuries sustained in the UK. Many patients experience pain and physical impairment, with the consequences of the fracture and its management lasting for several months or even years. The broad aim of ankle fracture treatment is to maintain the alignment of the joint while the fracture heals, and to reduce the risks of problems, such as stiffness. More severe injuries to the ankle are routinely treated surgically. However, even with advances in surgery, there remains a risk of complications; for patients experiencing these, the associated loss of function and quality of life (Qol) is considerable. Non-surgical treatment is an alternative to surgery and involves applying a cast carefully shaped to the patient's ankle to correct and maintain alignment of the joint with the key benefit being a reduction in the frequency of common complications of surgery. The main potential risk of non-surgical treatment is a loss of alignment with a consequent reduction in ankle function. This study aims to determine whether ankle function, four months after treatment, in patients with unstable ankle fractures treated with close contact casting is not worse than in those treated with surgical intervention, which is the current standard of care. Methods: This trial is a pragmatic, multicentre, randomized non-inferiority clinical trial with an embedded pilot, and with 12 months clinical follow-up and parallel economic analysis. A surveillance study using routinely collected data will be performed annually to five years post-treatment. Adult patients, aged 60 years and younger, with unstable ankle fractures will be identified in daily trauma meetings and fracture clinics and approached for recruitment prior to their treatment. Treatments will be performed in trauma units across the UK by a wide range of surgeons. Details of the surgical treatment, including how the operation is done, implant choice, and the recovery programme afterwards, will be at the discretion of the treating surgeon. The non-surgical treatment will be close-contact casting performed under anaesthetic, a technique which has gained in popularity since the publication of the Ankle Injury Management (AIM) trial. In all, 890 participants (445 per group) will be randomly allocated to surgical or non-surgical treatment. Data regarding ankle function, QoL, complications, and healthcare-related costs will be collected at eight weeks, four and 12 months, and then annually for five years following treatment. The primary outcome measure is patient-reported ankle function at four months from treatment. Anticipated impact: The 12-month results will be presented and published internationally. This is anticipated to be the only pragmatic trial reporting outcomes comparing surgical with non-surgical treatment in unstable ankle fractures in younger adults (aged 60 years and younger), and, as such, will inform the National Institute for Health and Care Excellence (NICE) 'non-complex fracture' recommendations at their scheduled update in 2024. A report of long-term outcomes at five years will be produced by January 2027.
