Abstract
Purpose The aim of this study is to analyze the clinical reality of pediatric trigger thumb among members of the European Paediatric Orthopaedic Society. Methods A 35-question survey was sent to all European Paediatric Orthopaedic Society members, focusing on surgeon's profile and experience, trigger thumb diagnostic and trigger thumb treatment approach. Descriptive statistics were performed. Results A total of 99 responses were analyzed. Most important factor considered in the therapeutic approach was the presence of a locked interphalangeal joint (52%). Regarding treatment, 41.4% opt for conservative approach as the first line of treatment, while 30.3% consider surgery and 28.3% just observe. Nevertheless, 76% mention to treat conservatively their patients and 99% to consider surgery at some stage. Regarding surgical technique, 96% do it open and 56% consider 2 years as the minimum age for procedure. Most surgeons perform this procedure in out-patient care (87%), don't administer prophylactic antibiotherapy (80%), use a tourniquet (75%), don't use any postoperative immobilization (64%), and report complications related to surgery (64%), mainly recurrence/incomplete division (59%) and superficial wound infection (30%). Conclusion Our study shows a significant variability in the initial management of pediatric trigger thumb with a predominance of conservative management, followed by surgery and observation without treatment. The disparity in treatment options and timing, or waiting times before moving on to different therapeutic options, shows us that this is a controversial issue and that the development of prospective randomized controlled studies is needed to analyze the different treatment methods and determine which ones give the best outcomes.

Karagüven D, Demir P, Yüksel S, Ömeroğlu H. A Delphi consensus study on the treatment of slipped capital femoral epiphysis: Considerable consensus in mild and moderate slips and limited consensus in severe slips. J Child Orthop 2023; 17:299-305. [PMID: 37565005 PMCID: PMC10411377 DOI: 10.1177/18632521231177272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 05/01/2023] [Indexed: 08/12/2023] Open
Abstract
Purpose The aim of this expert consensus study was to establish consensus on the treatment of different types of slipped capital femoral epiphysis and on the use of prophylactic screw fixation of the contralateral unaffected side. Methods In this study, a four-round Delphi method was used. Questionnaires including all possible theoretical slip scenarios were sent online to 14 participants, experienced in the field of children's orthopedics and in the treatment of hip disorders in children. Results In-situ fixation was considered to be the first treatment choice in all types of mild slip scenarios and in moderate, stable ones. Performing in-situ fixation was not favored in moderate, unstable, and in all severe slip scenarios. In moderate to severe, unstable slip scenarios, there was consensus on the use of gentle closed or open reduction and internal fixation. Any consensus was not established in the optimal treatment of severe, stable slips. There was also consensus on the use of prophylactic screw fixation of the contralateral side in case of co-existing endocrine disorder and younger age. Conclusions The establishment of consensus on the treatment of all types of slipped capital femoral epiphysis even among the experienced surgeons does not seem to be possible. The severity of the slip and stability of the slip are the primary and secondary determinants of the surgeons' treatment choices, respectively. In-situ fixation is still the preferred treatment option in several slip types. Gentle capital realignment by closed or open means is recommended in displaced, unstable slips. Prophylactic screw fixation of the contralateral side is indicated under certain circumstances. Level of evidence level V.

Tactics of Surgical Treatment of Slipped Capital Femoral Epiphysis Associated With Mild Chronic Epiphyseal Displacement. TRAUMATOLOGY AND ORTHOPEDICS OF RUSSIA 2022.

Abstract
Background. The appearing of data on cam-type FAI in patients with sequelae of slipped capital femoral epiphysis characterized by mild chronic epiphyseal displacement suggests that along with fixation of the proximal femoral epiphysis, modeling of the head-neck transition and restoration of the femoral offsets using arthroscopic techniques should be performed. Meanwhile, it is well known that after epiphyseal fixation, complete remodeling of the epimetaphysis and, consequently, disappearance of the morphological substrate of potential FAI can occur due to the ongoing enchondral and echondral growth. In this regard, the issue of indications for intraarticular interventions in studied patients remains currently open.
The aim of the study was to determine the incidence of FAI in the postoperative period in patients with slipped capital femoral epiphysis characterized by mild chronic epiphyseal displacement, and to estimate the requirement of further surgical treatment.
Methods. The results of the examination of 32 patients with mild chronic epiphyseal displacement in the typical posterior inferior direction who underwent cannulated epiphyseal screw fixation were analyzed for the severity of epimetaphysis remodeling and the presence of FAI in the postoperative period. Clinical, radiological, magnetic resonance, and statistical methods were used.
Results. At the age of 18-19 years, FAI with pain syndrome in everyday life was found in 9 (28.1%) patients 8 of them did not have even partial remodeling of the femoral component of the joint, another 9 (28.1%) patients did not suffer from pain syndrome in everyday life, but had other clinical, radiological and MR signs of cam-type FAI. Complete or almost complete remodeling of the proximal femoral epimetaphysis occurred in 14 (43.8%) patients.
Conclusion. In our opinion, therapeutic and diagnostic arthroscopy of the hip joint for the purpose of modeling the head-neck transition at the age of 18-19 years is indicated for more than one quarter (28.1%) of the investigated patients because of the presence of reliable signs of FAI.

Presence and magnitude of anterior physeal separation in slipped upper femoral epiphysis helps identifying those at high risk for avascular necrosis. Injury 2022; 53:4020-4027. [PMID: 36307269 DOI: 10.1016/j.injury.2022.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 08/29/2022] [Accepted: 10/17/2022] [Indexed: 11/05/2022]
Abstract
AIMS We sought to determine if the magnitude of anterior physeal separation (APS) in slipped upper femoral epiphysis was a predictor for the subsequent development of avascular necrosis (AVN). Anterior Physeal Separation (APS) is defined as the distance between the anterior lip of the bony capital epiphysis and the lateral corresponding point of the adjacent bony metaphysis on the Lauenstein radiographic view. It represents hinging of the posterior aspect of the metaphysis with the anterior epiphysis lifting away from its adjacent metaphysis, indicating instability and potential vulnerability of the vessels. PATIENTS AND METHODS A retrospective review of all patients treated regionally for slipped upper femoral epiphysis over a 9 year period (2010-2018 inclusive) were identified. Data regarding demographics, radiological parameters and outcomes was recorded. APS was measured on a Launestein radiograph view, with the patient supine, the hip and knee are flexed to 40°, and the hip externally rotated 45°, with film-focus distance of 100 cm. Analysis of the APS was performed to validate a threshold above which AVN occurs. RESULTS We identified 147 hips in 142 patients, of which 5 had bilateral slips at the time of presentation. Average anterior physeal separation was 3.8 ± 1.8 mm, with higher grade slips having significantly greater APS values. Increased APS values were seen with Loder "unstable" slips. Seven hips (4.8%) developed AVN, and in these cases the APS was significantly larger than those who did not (8.5 ± 1.4 Vs 3.9 ± 1.7; p < 0.001). Receiver operator curve analysis demonstrated a critical value of 7.5 mm was associated with a 100% sensitivity and 98.6% specificity for AVN. We identified some grade II/moderate slips with high APS values had similar outcomes to grade III/severe slips, and therefore suggest that APS may serve to alert the surgeon on counselling patients on the risk of developing AVN and to consider strategies to minimise the risk of AVN. CONCLUSIONS APS is sensitive, specific, accurate and reliable for the association with AVN in SUFE. Its values closely reflect the high AVN rates seen in acute and unstable SUFE. This risk is greatest if the magnitude of APS exceeds the critical value of 7.5 mm.

Current trends in the treatment of supracondylar fractures of the humerus in children: Results of a survey of the members of European Paediatric Orthopaedic Society. J Child Orthop 2022; 16:208-219. [PMID: 35800655 PMCID: PMC9254020 DOI: 10.1177/18632521221106379] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 05/19/2022] [Indexed: 02/03/2023] Open
Abstract
PURPOSE The purpose of this study was to evaluate the current trends in the treatment of supracondylar humerus fractures as well as the preferred post-operative follow-up protocol among members of the European Paediatric Orthopaedic Society. METHODS The survey was composed by four main domains and 26 items: (1) surgeon information (3 items); (2) treatment (8 items); (3) post-operative treatment (3 items); and (4) factors influencing the outcome (12 items). All active members of European Paediatric Orthopaedic Society were invited by email to answer an electronic questionnaire. RESULTS The survey was submitted to 397 European Paediatric Orthopaedic Society active members; 184 members answered (46.3%) the questionnaire. Among respondents, 64.1% declared >10 years of experience and 55.4% declared to treat >20 supracondylar humerus fractures per year. Closed reduction, percutaneous pinning, and supine position were the preferred treatment option for Gartland type II and III supracondylar humerus fractures by 79.9%, 95.5%, and 84.8% of respondents, respectively. Supracondylar humerus fractures are treated within 24 h from trauma by 33.2% of respondents. Pins are removed 4 weeks from index procedure by 58.2% of respondents. Fracture type (72.3%), surgeon experience, and (71.2%) are of "crucial importance" for expected outcome of supracondylar humerus fractures treatment. CONCLUSION Surgeon experience, type of fracture, treatment modality, and pins configuration were considered the main factors potentially influencing the outcome of supracondylar humerus fractures. European Paediatric Orthopaedic Society members agreed on the treatment modality of Gartland type II and III supracondylar humerus fractures, patient positioning, and timing of hardware removal. Other important issues such as timing of surgery, pins configuration, surgical approach, and post-operative protocol are still debated. LEVEL OF EVIDENCE level II.

Abstract
AIMS The aim of this study was to inform the epidemiology and treatment of slipped capital femoral epiphysis (SCFE). METHODS This was an anonymized comprehensive cohort study, with a nested consented cohort, following the the Idea, Development, Exploration, Assessment, Long-term study (IDEAL) framework. A total of 143 of 144 hospitals treating SCFE in Great Britain participated over an 18-month period. Patients were cross-checked against national administrative data and potential missing patients were identified. Clinician-reported outcomes were collected until two years. Patient-reported outcome measures (PROMs) were collected for a subset of participants. RESULTS A total of 486 children (513 hips) were newly affected, with a median of two patients (interquartile range 0 to 4) per hospital. The annual incidence was 3.34 (95% confidence interval (CI) 3.01 to 3.67) per 100,000 six- to 18-year-olds. Time to diagnosis in stable disease was increased in severe deformity. There was considerable variation in surgical strategy among those unable to walk at diagnosis (66 urgent surgery vs 43 surgery after interval delay), those with severe radiological deformity (34 fixation with deformity correction vs 36 without correction) and those with unaffected opposite hips (120 prophylactic fixation vs 286 no fixation). Independent risk factors for avascular necrosis (AVN) were the inability of the child to walk at presentation to hospital (adjusted odds ratio (aOR) 4.4 (95% CI 1.7 to 11.4)) and surgical technique of open reduction and internal fixation (aOR 7.5 (95% CI 2.4 to 23.2)). Overall, 33 unaffected untreated opposite hips (11.5%) were treated for SCFE by two-year follow-up. Age was the only independent risk factor for contralateral SCFE, with age under 12.5 years the optimal cut-off to define 'at risk'. Of hips treated with prophylactic fixation, none had SCFE, though complications included femoral fracture, AVN, and revision surgery. PROMs demonstrated the marked impact on quality of life on the child because of SCFE. CONCLUSION The experience of individual hospitals is limited and mechanisms to consolidate learning may enhance care. Diagnostic delays were common and radiological severity worsened with increasing time to diagnosis. There was unexplained variation in treatment, some of which exposes children to significant risks that should be evaluated through randomized controlled trials.

Abstract
The objectives of this study were to collect and analyze current diagnosis and treatment options of symptomatic flexible flatfoot (FFF), as well as to identify treatment expectations, among the members of the Italian Pediatric Orthopedics Society (SITOP). Diagnosis and treatment preferences were recorded according to a web-based survey. The survey was divided into six main sections: (1) general clinical parameters; (2) foot aspects; (3) X-ray angles (or lines); (4) expectations; (5) standard clinical assessment; (6) treatment options. One hundred and ten out of 248 SITOP members answered to the questionnaire. Age (85.5%), pain at the level of the plantar arch or fascia (61.8%), fatigue (59.1%) were the clinical parameters of crucial importance. Heel valgus (85.4%), flexibility (61.8%) and forefoot supination (47.3%) were identified as the most important foot aspects. Ninety-two responders (83.6%) identified the 'improved ability to walk longer without symptoms or discomfort' as the principal treatment expectation. Pain evaluated through the visual analog scale (VAS) was considered crucial in 31.8% of cases. All respondents confirmed they also treat patients with FFF surgically; in particular, 97.3% of SITOP affiliates declare to perform arthroereisis followed by lateral column lengthening (29.1%) and medializing calcaneal osteotomy (9.1%). Although in this survey heterogeneous findings for diagnosis and treatment of patients with symptomatic FFF within SITOP members were found, a large preference for age, heel valgus, flexibility as clinical aspects and parameters, as well as nonoperative treatment and arthroereisis, was reported.

Abstract
The aim of the study was to evaluate flexible flatfoot (FFF) diagnostic and current therapeutic modalities, as well as treatment expectations, among members of the European Paediatric Orthopaedic Society (EPOS). A 59-questions survey on FFF diagnosis and treatment preferences was distributed to EPOS members. The survey consisted of six sections (1) general clinical parameters; (2) foot aspects; (3) X-ray angles (or lines); (4) expectations; (5) standard clinical assessment; and (6) management options. Descriptive statistics were performed. A total of 93 responses were analysed. In general, clinical parameters, age (91.4% of cases), laxity (81.7%), diffuse pain (84.9%), and pain at the ankle joint (81.7%) were rated as 'average' and 'crucial importance' by the vast majority of respondents. Meary's angle (47.3% of cases), talonavicular coverage (35.5%), and lateral talocalcaneal angle (35.5%) were assessed as main radiological tools in the FFF evaluation. Among respondents, 61.3% rated 'improved ability to walk longer without symptoms' as of 'crucial importance'. Eighty-two percent of the respondents felt less than 10% of patients with FFF are candidates for corrective surgery. Arthroereisis (29.3%) was the most common surgical procedure (16.4% for subtalar and 12.9% for extra-articular arthroereisis, respectively), followed by lateral column lengthening (17.9%) and medializing calcaneal osteotomy (12.3%). There is great variation among respondents in diagnostic and treatment preferences in the management of children with FFF. The results of the EPOS 2019 FFF survey clearly show that large-scale, multicentric, international studies are necessary to elucidate which diagnostic and treatment practices lead to the best outcomes.

Abstract
Aims Slipped capital femoral epiphysis (SCFE) is one of the most common hip diseases of adolescence that can cause marked disability, yet there is little robust evidence to guide treatment. Fundamental aspects of the disease, such as frequency, are unknown and consequently the desire of clinicians to undertake robust intervention studies is somewhat prohibited by a lack of fundamental knowledge. Methods The study is an anonymized nationwide comprehensive cohort study with nested consented within the mechanism of the British Orthopaedic Surgery Surveillance (BOSS) Study. All relevant hospitals treating SCFE in England, Scotland, and Wales will contribute anonymized case details. Potential missing cases will be cross-checked against two independent external sources of data (the national administrative data and independent trainee data). Patients will be invited to enrich the data collected by supplementing anonymized case data with patient-reported outcome measures. In line with recommendations of the IDEAL Collaboration, the study will primarily seek to determine incidence, describe case mix and variations in surgical interventions, and explore the relationships between baseline factors (patients and types of interventions) and two-year outcomes. Discussion This is the first disease to be investigated using the BOSS Study infrastructure. It provides a robust method to determine the disease frequency, and a large unbiased sample of cases from which treatment strategies can be investigated. It may form the basis for definitive robust intervention studies or, where these are demonstrated not to be feasible, this may be the most robust cohort study.

Abstract
AIM To determine the preferred practices in the treatment of slipped capital femoral epiphysis (SCFE) among members of the Paediatric Orthopaedic Society of India (POSI). MATERIALS AND METHODS A questionnaire with 16 vignettes was made about SCFE and sent to all members of the Paediatric Orthopaedic Society of India (POSI) to study the similarity and variation in the management of SCFE. Specifically, respondents were asked about the role of reduction, methods of fixation, prophylactic fixation of the non-affected hip, postoperative management and their view on the prevalence of Femoro Acetabular Impingement (FAI) and anticipated need for secondary surgery. RESULTS The response rate was 94 out of 203 members of Paediatric Orthopaedic Surgeons of India (51.9%). 62 out of 94 (66%) participating surgeons had an exclusive paediatric orthopaedics workload, with 61 surgeons (65%) having more than ten years of experience. Seventy-eight surgeons (83%) were most consistent in their advice for the management of stable slips based on severity. For severe stable slips, 67 surgeons (71%) recommended Modified Dunn procedure. Around 23% of the respondents preferred to do modified Dunn's procedure for all unstable slips while the rest had different approaches to treat this. Single Partially threaded cancellous screw is the preferred implant for in-situ fixation, while a single screw and K wire construct is the preferred construct for in Modified Dunn's procedure. Only 17(16%) of the responders do prophylactic pinning of the opposite hip regularly. Almost 90 responders (96%) do counsel parents about FAI in later stages of life. CONCLUSION Our study documents that about 70% of the practising paediatric orthopaedic surgeons prefer to do capital realignment procedure for severe stable slips. The treatment of unstable slips remains controversial without any consensus though about 70% believe that there is a role of gentle reduction or positional reduction or skeletal traction. About 50% of the respondents treat less than five slips a year and thus would not possible to generate high-quality evidence based on meagre numbers. This clearly shows that there is a need for developing a national SCFE registry to pool in all data which would help us to arrive at meaningful conclusions to arrive at the ideal management guidelines for SCFE.

Abstract
The purpose of this study was to quantify three-dimensional translational and angular deformity (defined as theta) present at the proximal femoral physis in slipped capital femoral epiphysis (SCFE), and to use theta to differentiate between SCFE hips, contralateral unaffected hips, and normal hips by comparing to the current gold standard measure of the Southwick slip angle (SSA). 3DCT reconstructions of the pelvis and femur in SCFE patients and normal adolescents were obtained and pelvic position was standardized. The center point and direction vector of the femoral epiphysis was determined. The femoral neck axis was defined. The angle between the femoral neck axis and epiphysis vector defined the 3D angle of deformity (theta). The 3D translation of the femoral epiphysis, measured as a percentage of femoral neck diameter, was measured in three planes. The average theta angle was significantly greater in SCFE hips (46.5 ± 24.3°) compared with control (13.7 ± 6.4°) or normal (11.7 ± 3.7°) hips (p < 0.001). There was no significant difference in theta angle between control and normal hips (p = 0.468). Theta angle correlated strongly with SSA (rs = 0.737, p < 0.001). Statement of clinical significance: The proximal femoral deformity in patients with slipped capital femoral epiphysis can be defined by measuring displacement of the epiphysis in all three dimensions in relation to the femoral neck axis. This information can be used in epiphyseal reorientation surgery to ensure anatomic reduction. The similarity between control and normal hips may argue against the thought that there is pre-existing deformity in a pre-slip condition of unaffected contralateral hips in SCFE patients. © 2019 Orthopaedic Research Society.

Abstract
PURPOSE To understand the variation in the management of hip dysplasia identified from the United Kingdom neonatal selective screening programme. METHODS Having been designed and tested by the research committee of the British Society for Children's Orthopaedic Surgery (BSCOS), a nationwide online survey was conducted of BSCOS members to ascertain their treatment strategies for neonatal hip dysplasia. RESULTS There were 111 responses (60% of members), which illustrated wide variation in care. In all, 91 (over 80%) of respondents treat more than ten cases per year, yet only 61 (55%) work to an agreed protocol. A total of 90 (81%) use the Graf classification and 103 (93%) use the Pavlik harness initially. Consensus is lacking in key areas including duration of harness use, hours per day, clothing and weaning. Importantly, notable differences of opinion even exist regarding which hip pathologies need treatment. CONCLUSION This study quantifies the wide variation in many key elements of the initial treatment of neonatal hip dysplasia in the United Kingdom. This variation appears unnecessary and unacceptable as the Getting It Right First Time programme seeks to standardize care pathways. The charitable sector has called for consensus to mitigate parental anxiety, and it has been suggested that this could allow better integration of hip dysplasia into national screening pathways. Standardized care benefits patients and represents the platform from which we can begin understanding effectiveness and optimizing outcomes. LEVEL OF EVIDENCE Level V.

Abstract
BACKGROUND There is growing evidence that symptomatic femoroacetabular impingement (FAI) can develop after severe slipped capital femoral epiphysis (SCFE) fixed in situ. Realignment procedures have therefore gained popularity, but complication rates remain controversial. Among them, the subcapital shortening osteotomy without hip dislocation has been progressively adopted in France, but results have never been assessed to date. METHODS All cases performed in 23 French university hospitals between January 2010 and March 2014 were reviewed to (1) describe the surgical procedure, (2) assess the radiologic and functional outcomes, and (3) report complications and more specifically the avascular necrosis rate (AVN) according to initial stability. Stable and unstable SCFE were distinguished following Loder's definition. Radiologic outcomes were assessed by the 3 authors to determine FAI and osteonecrosis rates. Functional outcomes were evaluated at follow-up and complications were reported. RESULTS A total of 82 cases (45 unstable and 37 stable), performed in 10 institutions, were included with a mean follow-up of 25 months. No intraoperative complication occurred but 2 patients (2.4%) underwent unplanned early revision. Slip angle was significantly reduced (87%) without loss of correction. Overall AVN rate was 9.7%, reaching 13.3% in unstable slips. However, preoperative magnetic resonance imaging showed that most of the unstable epiphyses (4/6) were already hypoperfused before surgery. CONCLUSIONS The procedure is a reliable option for the treatment of severe SCFE. AVN rates are lower than previously reported in multicenter series of modified Dunn technique, especially in unstable slips. However, the risk of AVN in severe stable SCFE (5.4%) must still be balanced with the functional outcomes of potential future FAI. LEVEL OF EVIDENCE Level IV-therapeutic study.

Abstract
PURPOSE Slipped capital femoral epiphysis (SCFE) is an adolescent hip condition with a high risk of complication. The purpose of this study was to evaluate trends in treatment using a prospectively collected paediatric nationally representative database. METHODS A total of 9034 patients undergoing treatment for idiopathic SCFE were selected by querying the Healthcare Cost and Utilization Project's Kids' Inpatient Database for the years 1997, 2000, 2003, 2006, 2009 and 2012. The selected patients were separated based on operative approach and these cohorts were analyzed based on temporal and categorical differences in operative approach, patient demographics and clinical characteristics. Univariate and multivariate analyses were used when appropriate and the Mantel-Haenszel test for trend was used in temporal analysis. RESULTS Overall SCFE procedures have decreased 27.5% (p < 0.001). Closed procedures have decreased 28.5% (p < 0.001), while open procedures have decreased 44.8% (p < 0.001). Bilateral closed procedures have increased 7.2% (p < 0.001). The ratio of open to closed procedures decreased in patients aged nine to 12 years and increased in patients aged 13 to 16 years (p < 0.001). CONCLUSION Here we report age stratified trends in treatment for idiopathic SCFE using nationally representative data and show an overall decrease in admissions and procedures over time.

Abstract
Treatment of slipped capital femoral epiphysis remains a contentious and debated issue. The opinion for the correct method of treatment can differ not only between different continents and nations, but also between units and surgeons within individual units. We aim to review the European perspective on the treatment of slipped capital femoral epiphysis and consider the trends for treatment among the European orthopaedic surgical community.

Abstract
PURPOSE The aim of this study was to elucidate developmental dysplasia of the hip (DDH) diagnosis and treatment preferences among members of the Pediatric Orthopaedic Society of North America (POSNA) and European Paediatric Orthopaedic Society (EPOS). METHODS A 54-question survey on DDH diagnosis and treatment preferences was distributed to POSNA and EPOS members. Descriptive statistics were performed. RESULTS A total of 459 responses were analyzed. Ultrasound was the preferred modality for diagnosing DDH in infants less than six months old; few surgeons preferred radiographs. In all, 57% of POSNA members had radiology technicians perform ultrasounds, only 7% of EPOS members did. The percent coverage defining a dislocated hip varied greatly, the most frequent response being < 20% for POSNA and < 40% for EPOS members. Pavlik harnesses were the most popular harness/brace, used by 90% of POSNA and 71% of EPOS members. POSNA members were more likely than EPOS members to use a rigid abduction brace following initial harness/brace failure. For residual acetabular dysplasia, POSNA members were twice as likely as EPOS members to institute hip abduction bracing. Most surgeons would not perform closed reduction at less than three months of age or open reduction at less than six months of age. Most EPOS -members used traction prior to reduction; few POSNA members did. Few POSNA and EPOS members believed that reduction should be delayed until the ossific nucleus was visible. CONCLUSION There is great variation in the preferred methods for diagnosing and treating DDH. This survey is the largest transcontinental survey to compile diagnostic and treatment preferences for DDH. With wide variations in practice, there is room for quality improvement.

Abstract
Aims High-quality clinical research in children's orthopaedic surgery has lagged behind other surgical subspecialties. This study used a consensus-based approach to identify research priorities for clinical trials in children's orthopaedics. Methods A modified Delphi technique was used, which involved an initial scoping survey, a two-round Delphi process and an expert panel formed of members of the British Society of Children's Orthopaedic Surgery. The survey was conducted amongst orthopaedic surgeons treating children in the United Kingdom and Ireland. Results A total of 86 clinicians contributed to both rounds of the Delphi process, scoring priorities from one (low priority) to five (high priority). Elective topics were ranked higher than those relating to trauma, with the top ten elective research questions scoring higher than the top question for trauma. Ten elective, and five trauma research priorities were identified, with the three highest ranked questions relating to the treatment of slipped capital femoral epiphysis (mean score 4.6/ 5), Perthes' disease (4.5) and bone infection (4.5). Conclusion This consensus-based research agenda will guide surgeons, academics and funders to improve the evidence in children's orthopaedic surgery and encourage the development of multicentre clinical trials.

Southwick angle measurements and SCFE slip severity classifications are affected by frog-lateral positioning. Skeletal Radiol 2018; 47:79-84.

Abstract
OBJECTIVE Slipped capital femoral epiphysis (SCFE) is a hip disorder where the femoral head slips relative to the neck at the physis. Appropriate treatment of SCFE depends on the severity of the slip, commonly categorised using the Southwick (SW) angle. The SW angle is measured in the frog-lateral leg position, which can be painful and potentially unattainable for patients. The purpose of this study is to determine how errors in frog-lateral radiograph positioning affect measured SW angles and slip classifications. METHODS Models of SCFE hips were produced from one CT scan of a normal hip; 360 deformities were created. SW angles were measured from a simulated frog-lateral position. Femoral lateral head-neck angles (LHNA; equivalent to SW in incorrect frog-lateral plane) were measured over a range of 837 incorrect frog-lateral leg positions with positioning errors in flexion and/or internal/external rotation. RESULTS Seventy-six per cent of all imaging position-deformity combinations had error in the reported angle (>1° difference between LHNA and SW). Of those, 70% had <5°, 24% had 5° to 10°, and 6% had >10° of error from the actual SW angle. Three per cent of LHNAs that had >10° error resulted from <10° of positioning error. CONCLUSIONS If the patient is limited in flexion or external rotation, more diagnostic testing should be considered if error in the reported slip measurement would affect treatment decisions or if accurate severity classification is needed for research. Small positioning errors in moderate and severe slips can cause a > 10° LHNA error; additional three-dimensional imaging should be considered.

Abstract
The aim of this study was to assess contemporary management of slipped capital femoral epiphysis (SCFE) by surveying members of the British Society of Children's Orthopaedic Surgery (BSCOS). A questionnaire with five case vignettes was used. Two questions examined the timing of surgery for an acute unstable SCFE in a child presenting at 6 and 48 h after start of symptoms. Two further questions explored the preferred method of fixation in mild and severe stable SCFE. The final question examined the management of the contralateral normal hip. Responses were entered into an Excel spreadsheet and the data was analysed using a χ-test. The response rate was 56% (110/196). Overall, 88% (97/110) responded that if a child presented with an acute unstable SCFE within 6 h, they would treat it within 24 h of presentation, compared with 41% (45/110) for one presenting 48 h after the onset of symptoms (P<0.0001). Overall, 53% (58/110) of surveyed BSCOS members would offer surgery for an unstable SCFE between 1 and 7 days after onset of symptoms. Single screw fixation in situ for mild stable SCFE was advocated by 96% (106/110) with 71% (78/110) using this method for the treatment of severe stable SCFE. Corrective osteotomy is used by 2% (2/110) and 25% (28/110) of respondents for mild and severe stable SCFE, respectively (P<0.0001). Surgeons preferring osteotomy are more likely to perform an intracapsular technique. Prophylactic fixation of the contralateral normal hip was performed by 27% (30/110) of respondents. There are significant differences in opinions between BSCOS members as to the optimal management of SCFE. This reflects the variable recommendations and quality in the current scientific literature. Further research is therefore required to determine best practice and enable consensus to be reached.

Abstract
BACKGROUND In situ pinning, a low-risk treatment for slipped capital femoral epiphysis (SCFE), leaves the slipped femoral head in place and may reduce range of motion (ROM) and cause impingement. It is unclear when a more complex surgery should be considered, because the relationships between severity, slip stability, remodeling, impingement, and ROM are unknown. RESEARCH QUESTIONS (1) Do more severe acute SCFE deformities (no bony remodeling) result in a greater loss of flexion ROM?(2) Does the presence or location of impingement on the pelvis vary with severity of acute SCFE deformity? METHODS We developed a 3D geometric model of acute SCFE deformity from 1 computed tomography scan of a normal adolescent hip. Ethics board approval was obtained from our institution. Bone models were created from the segmented pelvis, epiphysis, and subphyseal femur.In total, 3721 SCFE deformities were simulated by combining posterior and inferior slips in the axial and coronal planes, respectively. Southwick angles were estimated from a frog-leg lateral projection. Deformities were divided into mild (0 to 30 degrees), moderate (30 to 60 degrees), and severe (≥60 degrees) Southwick groups. Each joint was flexed in combination with internal/external rotation until contact occurred. A total of 121 ROM trials, with different degrees of internal/external rotation (0 to 90 degrees at 1.5-degree steps) were performed for each deformity. RESULTS In total, 3355 simulated SCFE deformities (363 could not be rotated out of impingement) were analyzed.Increasing slip severity reduced flexion ROM across the range of internal/external rotation. Contact occurred for most mild deformities, and for all moderate and severe deformities in at least 1 ROM trial. Impingement was observed mainly on the anterosuperior aspect of the acetabulum. CONCLUSIONS Increasing slip severity in acute SCFE reduced flexion and increased incidence of impingement, primarily occurring on the anterosuperior aspect of the acetabulum. The impingement patterns observed are consistent with damaged cartilage locations seen in clinical literature. CLINICAL RELEVANCE In this experimental model, moderate and severe acute slips in SCFE lead to reduced ROM and impingement with the acetabulum. This suggests that in situ pinning may result in impingement of moderate and severe acute SCFE slips.

Abstract
Slipped capital femoral epiphysis (SCFE) is a common hip condition that can be disabling. In this review, we provide an orientation on current trends in the clinical management of SCFE including conventional procedures and specialised surgical developments. Different methods of fixation of the epiphysis, risks of complications, and the rationale of addressing deformity, primarily or secondarily, are presented. Although improved understanding of the anatomy, vascularity and implications of residual deformity have changed management strategies, the best modality of treatment that would restore complete vascularity to the femoral head and prevent any residual deformity, impingement and early osteoarthritis remains elusive.

Abstract
We undertook a retrospective comparative study of all patients with an unstable slipped capital femoral epiphysis presenting to a single centre between 1998 and 2011. There were 45 patients (46 hips; mean age 12.6 years; 9 to 14); 16 hips underwent intracapsular cuneiform osteotomy and 30 underwent pinning in situ, with varying degrees of serendipitous reduction. No patient in the osteotomy group was lost to follow-up, which was undertaken at a mean of 28 months (11 to 48); four patients in the pinning in situ group were lost to follow-up, which occurred at a mean of 30 months (10 to 50). Avascular necrosis (AVN) occurred in four hips (25%) following osteotomy and in 11 (42%) following pinning in situ. AVN was not seen in five hips for which osteotomy was undertaken > 13 days after presentation. AVN occurred in four of ten (40%) hips undergoing emergency pinning in situ, compared with four of 15 (47%) undergoing non-emergency pinning. The rate of AVN was 67% (four of six) in those undergoing pinning on the second or third day after presentation. Pinning in situ following complete reduction led to AVN in four out of five cases (80%). In comparison, pinning in situ following incomplete reduction led to AVN in 7 of 21 cases (33%). The rate of development of AVN was significantly higher following pinning in situ with complete reduction than following intracapsular osteotomy (p = 0.048). Complete reduction was more frequent in those treated by emergency pinning and was strongly associated with AVN (p = 0.005). Non-emergency intracapsular osteotomy may have a protective effect on the epiphyseal vasculature and should be undertaken with a delay of at least two weeks. The place of emergency pinning in situ in these patients needs to be re-evaluated, possibly in favour of an emergency open procedure or delayed intracapsular osteotomy. Non-emergency pinning in situ should be undertaken after a delay of at least five days, with the greatest risk at two and three days after presentation. Intracapsular osteotomy should be undertaken after a delay of at least 14 days. In our experience, closed epiphyseal reduction is harmful. Cite this article: Bone Joint J 2015;97-B:412–19.

Abstract
BACKGROUND Slipped capital femoral epiphysis is known to produce characteristic deformities in the proximal femur, which affect hip motion and may cause a limp. This paper assessed the 3D gait kinematics in adolescents after single screw fixation of moderate to severe, stable, unilateral slipped capital femoral epiphysis. Our goals were to characterize the 3D kinematic patterns and to investigate the correlation between the severity of radiological deformity and severity of gait disturbance. METHODS This was a retrospective study of patients seen at our institution between 2000 and 2009. Antero-posterior and frog lateral X-rays were reviewed to measure: Southwick's lateral slip angle, the alpha angle of Notzli and Klein's line offset. Quantitative 3D gait data was collected using a state of the art motion capture system. Kinematic waveforms were compared using a functional data analysis version of the t-test. FINDINGS There were 30 patients with an average age at pinning of 13y (10-17y). Mean gait profile scores were significantly abnormal for slipped side (10.8°) versus sound side (6.8°), slipped side versus normal (5.6°) and sound side versus normal. There was little statistically significant correlation between severity of radiographic deformity and degree of gait disturbance. INTERPRETATION Major kinematic pattern deviations could be associated with (a) morphology of the proximal femur and potential femoral acetabular impingement problems and (b) leg length discrepancy. Gait analysis was able to quantify the kinematic deviations due to the anatomical deformities.

Abstract
Slipped capital femoral epiphysis (SCFE) is characterized by displacement of the capital femoral epiphysis from the metaphysis through the physis. The term is confusing, because the metaphysis moves upward and outward while the epiphysis remains in the acetabulum. The SCFE is considered stable when the child is able to walk with or without crutches, and it is considered unstable when the child cannot walk with or without crutches. Patients with SCFE present with pain in the groin, knee and limp. The current treatment of stable SCFE is in situ stabilization with a single screw.

Abstract
We present our experience of the modified Dunn procedure in combination with a Ganz surgical dislocation of the hip to treat patients with severe slipped capital femoral epiphysis (SCFE). The aim was to prospectively investigate whether this technique is safe and reproducible. We assessed the degree of reduction, functional outcome, rate of complications, radiological changes and range of movement in the hip. There were 28 patients with a mean follow-up of 38.6 months (24 to 84). The lateral slip angle was corrected by a mean of 50.9° (95% confidence interval 44.3 to 57.5). The mean modified Harris hip score at the final follow-up was 89.1 (sd 9.0) and the mean Non-Arthritic Hip score was 91.3 (sd 9.0). Two patients had proven pre-existing avascular necrosis and two developed the condition post-operatively. There were no cases of nonunion, implant failure, infection, deep-vein thrombosis or heterotopic ossification. The range of movement at final follow-up was nearly normal. This study adds to the evidence that the technique of surgical dislocation and anatomical reduction is safe and reliable in patients with SCFE. Cite this article: Bone Joint J 2013;95-B:424–9.

Abstract
The evaluation of complex interventions, such as Single Event Multilevel Surgery (SEMLS) requires more than randomized controlled trials. Rehabilitation following SEMLS is prolonged and the outcomes of interest may not be apparent for 5 years or more after the surgery. We suggest long term, prospective cohort studies with objective outcome measures be recognized as of equal importance to randomized controlled trials. The evidence in support of instrumented gait analysis (IGA) is also reviewed. We suggest that clinical levels of evidence are not an appropriate method to evaluate a measurement tool. Specifically, IGA should be evaluated in terms of validity, reliability and cost effectiveness. We demonstrate that the use of IGA has improved medium and long term outcomes in ambulant children with cerebral palsy in a center where IGA has been used routinely both for planning SEMLS and for monitoring outcomes.
