Aims

The aim of this trial was to assess the cost-effectiveness of a soft bandage and immediate discharge, compared with rigid immobilization, in children aged four to 15 years with a torus fracture of the distal radius.

Methods

A within-trial economic evaluation was conducted from the UK NHS and personal social services (PSS) perspective, as well as a broader societal point of view. Health resources and quality of life (the youth version of the EuroQol five-dimension questionnaire (EQ-5D-Y)) data were collected, as part of the Forearm Recovery in Children Evaluation (FORCE) multicentre randomized controlled trial over a six-week period, using trial case report forms and patient-completed questionnaires. Costs and health gains (quality-adjusted life years (QALYs)) were estimated for the two trial treatment groups. Regression was used to estimate the probability of the new treatment being cost-effective at a range of ‘willingness-to-pay’ thresholds, which reflect a range of costs per QALY at which governments are typically prepared to reimburse for treatment.

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’.

Aims

The management of fractures of the medial epicondyle is one of the greatest controversies in paediatric fracture care, with uncertainty concerning the need for surgery. The British Society of Children’s Orthopaedic Surgery prioritized this as their most important research question in paediatric trauma. This is the protocol for a randomized controlled, multicentre, prospective superiority trial of operative fixation versus nonoperative treatment for displaced medial epicondyle fractures: the Surgery or Cast of the EpicoNdyle in Children’s Elbows (SCIENCE) trial.

Methods

Children aged seven to 15 years old inclusive, who have sustained a displaced fracture of the medial epicondyle, are eligible to take part. Baseline function using the Patient-Reported Outcomes Measurement Information System (PROMIS) upper limb score, pain measured using the Wong Baker FACES pain scale, and quality of life (QoL) assessed with the EuroQol five-dimension questionnaire for younger patients (EQ-5D-Y) will be collected. Each patient will be randomly allocated (1:1, stratified using a minimization algorithm by centre and initial elbow dislocation status (i.e. dislocated or not-dislocated at presentation to the emergency department)) to either a regimen of the operative fixation or non-surgical treatment.

Aims

The present study seeks to investigate the correlation of pubofemoral distances (PFD) to α angles, and hip displaceability status, defined as femoral head coverage (FHC) or FHC during manual provocation of the newborn hip < 50%.

Methods

We retrospectively included all newborns referred for ultrasound screening at our institution based on primary risk factor, clinical, and PFD screening. α angles, PFD, FHC, and FHC at follow-up ultrasound for referred newborns were measured and compared using scatter plots, linear regression, paired t-test, and box-plots.

Aims

The Ponseti method is the gold standard treatment for congenital talipes equinovarus (CTEV), with the British Consensus Statement providing a benchmark for standard of care. Meeting these standards and providing expert care while maintaining geographical accessibility can pose a service delivery challenge. A novel ‘Hub and Spoke’ Shared Care model was initiated to deliver Ponseti treatment for CTEV, while addressing standard of care and resource allocation. The aim of this study was to assess feasibility and outcomes of the corrective phase of Ponseti service delivery using this model.

Methods

Patients with idiopathic CTEV were seen in their local hospitals (‘Spokes’) for initial diagnosis and casting, followed by referral to the tertiary hospital (‘Hub’) for tenotomy. Non-idiopathic CTEV was managed solely by the Hub. Primary and secondary outcomes were achieving primary correction, and complication rates resulting in early transfer to the Hub, respectively. Consecutive data were prospectively collected and compared between patients allocated to Hub or Spokes. Mann-Whitney U test, Wilcoxon signed-rank test, or chi-squared tests were used for analysis (alpha-priori = 0.05, two-tailed significance).

Aims

Hip disease is common in children with cerebral palsy (CP) and can decrease quality of life and function. Surveillance programmes exist to improve outcomes by treating hip disease at an early stage using radiological surveillance. However, studies and surveillance programmes report different radiological outcomes, making it difficult to compare. We aimed to identify the most important radiological measurements and develop a core measurement set (CMS) for clinical practice, research, and surveillance programmes.

Methods

A systematic review identified a list of measurements previously used in studies reporting radiological hip outcomes in children with CP. These measurements informed a two-round Delphi study, conducted among orthopaedic surgeons and specialist physiotherapists. Participants rated each measurement on a nine-point Likert scale (‘not important’ to ‘critically important’). A consensus meeting was held to finalize the CMS.

Aims

Accurate skeletal age and final adult height prediction methods in paediatric orthopaedics are crucial for determining optimal timing of growth-guiding interventions and minimizing complications in treatments of various conditions. This study aimed to evaluate the accuracy of final adult height predictions using the central peak height (CPH) method with long leg X-rays and four different multiplier tables.

Methods

This study included 31 patients who underwent temporary hemiepiphysiodesis for varus or valgus deformity of the leg between 2014 and 2020. The skeletal age at surgical intervention was evaluated using the CPH method with long leg radiographs. The true final adult height (FHTRUE) was determined when the growth plates were closed. The final height prediction accuracy of four different multiplier tables (1. Bayley and Pinneau; 2. Paley et al; 3. Sanders – Greulich and Pyle (SGP); and 4. Sanders – peak height velocity (PHV)) was then compared using either skeletal age or chronological age.

Aims

Perthes’ disease is an idiopathic avascular necrosis of the developing femoral head, often causing deformity that impairs physical function. Current treatments aim to optimize the joint reaction force across the hip by enhancing congruency between the acetabulum and femoral head. Despite a century of research, there is no consensus regarding the optimal treatment. The aim of this study was to describe the experiences of children, their families, and clinicians when considering the treatment of Perthes’ disease.

Methods

A qualitative study gathered information from children and their families affected by Perthes’ disease, along with treating clinicians. Interviews followed a coding framework, with the interview schedule informed by behavioural theory and patient and public involvement. Transcripts were analyzed using the framework method.

Aims

Developmental dysplasia of the hip (DDH) can be managed effectively with non-surgical interventions when diagnosed early. However, the likelihood of surgical intervention increases with a late presentation. Therefore, an effective screening programme is essential to prevent late diagnosis and reduce surgical morbidity in the population.

Methods

We conducted a systematic review and meta-analysis of the epidemiological literature from the last 25 years in the UK. Articles were selected from databases searches using MEDLINE, EMBASE, OVID, and Cochrane; 13 papers met the inclusion criteria.


Aims

The purpose of this study was to assess the reliability and responsiveness to hip surgery of a four-point modified Care and Comfort Hypertonicity Questionnaire (mCCHQ) scoring tool in children with cerebral palsy (CP) in Gross Motor Function Classification System (GMFCS) levels IV and V.

Methods

This was a population-based cohort study in children with CP from a national surveillance programme. Reliability was assessed from 20 caregivers who completed the mCCHQ questionnaire on two occasions three weeks apart. Test-retest reliability of the mCCHQ was calculated, and responsiveness before and after surgery for a displaced hip was evaluated in a cohort of children.

Aims

Brace treatment is the cornerstone of managing developmental dysplasia of the hip (DDH), yet there is a lack of evidence-based treatment protocols, which results in wide variations in practice. To resolve this, we have developed a comprehensive nonoperative treatment protocol conforming to published consensus principles, with well-defined a priori criteria for inclusion and successful treatment.

Methods

This was a single-centre, prospective, longitudinal cohort study of a consecutive series of infants with ultrasound-confirmed DDH who underwent a comprehensive nonoperative brace management protocol in a unified multidisciplinary clinic between January 2012 and December 2016 with five-year follow-up radiographs. The radiological outcomes were acetabular index-lateral edge (AI-L), acetabular index-sourcil (AI-S), centre-edge angle (CEA), acetabular depth ratio (ADR), International Hip Dysplasia Institute (IHDI) grade, and evidence of avascular necrosis (AVN). At five years, each hip was classified as normal (< 1 SD), borderline dysplastic (1 to 2 SDs), or dysplastic (> 2 SDs) based on validated radiological norm-referenced values.

Aims

The aim of this study was to identify the information topics that should be addressed according to the parents of children with developmental dysplasia of the hip (DDH) in the diagnostic and treatment phase during the first year of life. Second, we explored parental recommendations to further optimize the information provision in DDH care.

Methods

A qualitative study with semi-structured interviews was conducted between September and December 2020. A purposive sample of parents of children aged younger than one year, who were treated for DDH with a Pavlik harness, were interviewed until data saturation was achieved. A total of 20 interviews with 22 parents were conducted. Interviews were audio recorded, transcribed verbatim, independently reviewed, and coded into categories and themes.

Aims

The aim of this study was to determine the consensus best practice approach for the investigation and management of children (aged 0 to 15 years) in the UK with musculoskeletal infection (including septic arthritis, osteomyelitis, pyomyositis, tenosynovitis, fasciitis, and discitis). This consensus can then be used to ensure consistent, safe care for children in UK hospitals and those elsewhere with similar healthcare systems.

Methods

A Delphi approach was used to determine consensus in three core aspects of care: 1) assessment, investigation, and diagnosis; 2) treatment; and 3) service, pathways, and networks. A steering group of paediatric orthopaedic surgeons created statements which were then evaluated through a two-round Delphi survey sent to all members of the British Society for Children’s Orthopaedic Surgery (BSCOS). Statements were only included (‘consensus in’) in the final agreed consensus if at least 75% of respondents scored the statement as critical for inclusion. Statements were discarded (‘consensus out’) if at least 75% of respondents scored them as not important for inclusion. Reporting these results followed the Appraisal Guidelines for Research and Evaluation.

Aims

This study aimed to evaluate the relationship between hip shape and mid-term function in Perthes’ disease. It also explored whether the modified three-group Stulberg classification can offer similar prognostic information to the five-group system.

Methods

A total of 136 individuals aged 12 years or older who had Perthes’ disease in childhood completed the Patient-Reported Outcomes Measurement Information System (PROMIS) Mobility score (function), Nonarthritic Hip Score (NAHS) (function), EuroQol five-dimension five-level questionnaire (EQ-5D-5L) score (quality of life), and the numeric rating scale for pain (NRS). The Stulberg class of the participants’ hip radiographs were evaluated by three fellowship-trained paediatric orthopaedic surgeons. Hip shape and Stulberg class were compared to PROM scores.

Aims

Reimers migration percentage (MP) is a key measure to inform decision-making around the management of hip displacement in cerebral palsy (CP). The aim of this study is to assess validity and inter- and intra-rater reliability of a novel method of measuring MP using a smart phone app (HipScreen (HS) app).

Methods

A total of 20 pelvis radiographs (40 hips) were used to measure MP by using the HS app. Measurements were performed by five different members of the multidisciplinary team, with varying levels of expertise in MP measurement. The same measurements were repeated two weeks later. A senior orthopaedic surgeon measured the MP on picture archiving and communication system (PACS) as the gold standard and repeated the measurements using HS app. Pearson’s correlation coefficient (r) was used to compare PACS measurements and all HS app measurements and assess validity. Intraclass correlation coefficient (ICC) was used to assess intra- and inter-rater reliability.

Aims

Early detection of developmental dysplasia of the hip (DDH) is associated with improved outcomes of conservative treatment. Therefore, we aimed to evaluate a novel screening programme that included both the primary risk factors of breech presentation and family history, and the secondary risk factors of oligohydramnios and foot deformities.

Methods

A five-year prospective registry study investigating every live birth in the study’s catchment area (n = 27,731), all of whom underwent screening for risk factors and examination at the newborn and six- to eight-week neonatal examination and review. DDH was diagnosed using ultrasonography and the Graf classification system, defined as grade IIb or above or rapidly regressing IIa disease (≥4o at four weeks follow-up). Multivariate odds ratios were calculated to establish significant association, and risk differences were calculated to provide quantifiable risk increase with DDH, positive predictive value was used as a measure of predictive efficacy. The cost-effectiveness of using these risk factors to predict DDH was evaluated using NHS tariffs (January 2021).

Aims

Within healthcare, several measures are used to quantify and compare the severity of health conditions. Two common measures are disability weight (DW), a context-independent value representing severity of a health state, and utility weight (UW), a context-dependent measure of health-related quality of life. Neither of these measures have previously been determined for developmental dysplasia of the hip (DDH). The aim of this study is to determine the DW and country-specific UWs for DDH.

Methods

A survey was created using three different methods to estimate the DW: a preference ranking exercise, time trade-off exercise, and visual analogue scale (VAS). Participants were fully licensed orthopaedic surgeons who were contacted through national and international orthopaedic organizations. A global DW was calculated using a random effects model through an inverse-variance approach. A UW was calculated for each country as one minus the country-specific DW composed of the time trade-off exercise and VAS.

Aims

A national screening programme has existed in the UK for the diagnosis of developmental dysplasia of the hip (DDH) since 1969. However, every aspect of screening and treatment remains controversial. Screening programmes throughout the world vary enormously, and in the UK there is significant variation in screening practice and treatment pathways. We report the results of an attempt by the British Society for Children’s Orthopaedic Surgery (BSCOS) to identify a nationwide consensus for the management of DDH in order to unify treatment and suggest an approach for screening.

Methods

A Delphi consensus study was performed among the membership of BSCOS. Statements were generated by a steering group regarding aspects of the management of DDH in children aged under three months, namely screening and surveillance (15 questions), the technique of ultrasound scanning (eight questions), the initiation of treatment (19 questions), care during treatment with a splint (ten questions), and on quality, governance, and research (eight questions). A two-round Delphi process was used and a consensus document was produced at the final meeting of the steering group.

Aims

Studies of infant hip development to date have been limited by considering only the changes in appearance of a single ultrasound slice (Graf’s standard plane). We used 3D ultrasound (3DUS) to establish maturation curves of normal infant hip development, quantifying variation by age, sex, side, and anteroposterior location in the hip.

Methods

We analyzed 3DUS scans of 519 infants (mean age 64 days (6 to 111 days)) presenting at a tertiary children’s hospital for suspicion of developmental dysplasia of the hip (DDH). Hips that did not require ultrasound follow-up or treatment were classified as ‘typically developing’. We calculated traditional DDH indices like α angle (αSP), femoral head coverage (FHCSP), and several novel indices from 3DUS like the acetabular contact angle (ACA) and osculating circle radius (OCR) using custom software.

Aims

Slipped upper femoral epiphysis (SUFE) has well documented biochemical and mechanical risk factors. Femoral and acetabular morphologies seem to be equally important. Acetabular retroversion has a low prevalence in asymptomatic adults. Hips with dysplasia, osteoarthritis, and Perthes’ disease, however, have higher rates, ranging from 18% to 48%. The aim of our study was to assess the prevalence of acetabular retroversion in patients presenting with SUFE using both validated radiological signs and tomographical measurements.

Methods

A retrospective review of all SUFE surgical cases presenting to the Royal Children’s Hospital, Melbourne, Australia, from 2012 to 2019 were evaluated. Preoperative plain radiographs were assessed for slip angle, validated radiological signs of retroversion, and standardized postoperative CT scans were used to assess cranial and mid-acetabular version.

Aims

To identify the minimum set of outcomes that should be collected in clinical practice and reported in research related to the care of children with idiopathic congenital talipes equinovarus (CTEV).

Methods

A list of outcome measurement tools (OMTs) was obtained from the literature through a systematic review. Further outcomes were collected from patients and families through a questionnaire and interview process. The combined list, as well as the appropriate follow-up timepoint, was rated for importance in a two-round Delphi process that included an international group of orthopaedic surgeons, physiotherapists, nurse practitioners, patients, and families. Outcomes that reached no consensus during the Delphi process were further discussed and scored for inclusion/exclusion in a final consensus meeting involving international stakeholder representatives of practitioners, families, and patient charities.

Aims

To determine the likelihood of achieving a successful closed reduction (CR) of a dislocated hip in developmental dysplasia of the hip (DDH) after failed Pavlik harness treatment We report the rate of avascular necrosis (AVN) and the need for further surgical procedures.

Methods

Data was obtained from the Northern Ireland DDH database. All children who underwent an attempted closed reduction between 2011 and 2016 were identified. Children with a dislocated hip that failed Pavlik harness treatment were included in the study. Successful closed reduction was defined as a hip that reduced in theatre and remained reduced. Most recent imaging was assessed for the presence of AVN using the Kalamchi and MacEwen classification.

Aims

Temporary epiphysiodesis (ED) is commonly applied in children and adolescents to treat leg length discrepancies (LLDs) and tall stature. Traditional Blount staples or modern two-hole plates are used in clinical practice. However, they require accurate planning, precise surgical techniques, and attentive follow-up to achieve the desired outcome without complications. This study reports the results of ED using a novel rigid staple (RigidTack) incorporating safety, as well as technical and procedural success according to the idea, development, evaluation, assessment, long-term (IDEAL) study framework.

Methods

A cohort of 56 patients, including 45 unilateral EDs for LLD and 11 bilateral EDs for tall stature, were prospectively analyzed. ED was performed with 222 rigid staples with a mean follow-up of 24.4 months (8 to 49). Patients with a predicted LLD of ≥ 2 cm at skeletal maturity were included. Mean age at surgery was 12.1 years (8 to 14). Correction and complication rates including implant-associated problems, and secondary deformities as well as perioperative parameters, were recorded (IDEAL stage 2a). These results were compared to historical cohorts treated for correction of LLD with two-hole plates or Blount staples.

Aims

This study aims to define a set of core outcomes (COS) to allow consistent reporting in order to compare results and assist in treatment decisions for idiopathic clubfoot.

Methods

A list of outcomes will be obtained in a three-stage process from the literature and from key stakeholders (patients, parents, surgeons, and healthcare professionals). Important outcomes for patients and parents will be collected from a group of children with idiopathic clubfoot and their parents through questionnaires and interviews. The outcomes identified during this process will be combined with the list of outcomes previously obtained from a systematic review, with each outcome assigned to one of the five core areas defined by the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT). This stage will be followed by a two round Delphi survey aimed at key stakeholders in the management of idiopathic clubfoot. The final outcomes list obtained will then be discussed in a consensus meeting of representative key stakeholders.

Aims

Open reduction in developmental dysplasia of the hip (DDH) is regularly performed despite screening programmes, due to failure of treatment or late presentation. A protocol for open reduction of DDH has been refined through collaboration between surgical, anaesthetic, and nursing teams to allow same day discharge. The objective of this study was to determine the safety and feasibility of performing open reduction of DDH as a day case.

Methods

A prospectively collected departmental database was visited. All consecutive surgical cases of DDH between June 2015 and March 2020 were collected. Closed reductions, bilateral cases, cases requiring corrective osteotomy, and children with comorbidities were excluded. Data collected included demographics, safety outcome measures (blood loss, complications, readmission, reduction confirmation), and feasibility for discharge according to the Face Legs Activity Cry Consolidability (FLACC) pain scale. A satisfaction questionnaire was filled by the carers. Descriptive statistics were used for analysis.

Aims

This observational study examines the effect of the COVID-19 pandemic upon the paediatric trauma burden of a district general hospital. We aim to compare the nature and volume of the paediatric trauma during the first 2020 UK lockdown period with the same period in 2019.

Methods

Prospective data was collected from 23 March 2020 to 14 June 2020 and compared with retrospective data collected from 23 March 2019 to 14 June 2019. Patient demographics, mechanism of injury, nature of the injury, and details of any surgery were tabulated and statistically analyzed using the independent-samples t-test for normally distributed data and the Mann-Whitney-U test for non-parametric data. Additionally, patients were contacted by telephone to further explore the mechanism of injury where required, to gain some qualitative insight into the risk factors for injury.

Aims

Hip displacement, common in patients with cerebral palsy (CP), causes pain and hinders adequate care. Hip reconstructive surgery (HRS) is performed to treat hip displacement; however, only a few studies have quantitatively assessed femoral head sphericity after HRS. The aim of this study was to quantitatively assess improvement in hip sphericity after HRS in patients with CP.

Methods

We retrospectively analyzed hip radiographs of patients who had undergone HRS because of CP-associated hip displacement. The pre- and postoperative migration percentage (MP), femoral neck-shaft angle (NSA), and sphericity, as determined by the Mose hip ratio (MHR), age at surgery, Gross Motor Function Classification System level, surgical history including Dega pelvic osteotomy, and triradiate cartilage status were studied. Regression analyses using linear mixed model were performed to identify factors affecting hip sphericity improvement.

Aims

Perthes’ disease is a condition leading to necrosis of the femoral head. It is most common in children aged four to nine years, affecting around one per 1,200 children in the UK. Management typically includes non-surgical treatment options, such as physiotherapy with/without surgical intervention. However, there is significant variation in care with no consensus on the most effective treatment option.

Methods

This systematic review aims to evaluate the effectiveness of non-surgical interventions for the treatment of Perthes’ disease. Comparative studies (experimental or observational) of any non-surgical intervention compared directly with any alternative intervention (surgical, non-surgical or no intervention) were identified from: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMcare, Allied and Complementary Medicine Database (AMED), and the Physiotherapy Evidence Database (PEDro). Data were extracted on interventions compared and methodological quality. For post-intervention primary outcome of radiological scores (Stulberg and/or Mose), event rates for poor scores were calculated with significance values. Secondary outcomes included functional measures, such as range of movement, and patient-reported outcomes such as health-related quality of life.

Aims

Perthes’ disease is a condition which leads to necrosis of the femoral head. It is most commonly reported in children aged four to nine years, with recent statistics suggesting it affects around five per 100,000 children in the UK. Current treatment for the condition aims to maintain the best possible environment for the disease process to run its natural course. Management typically includes physiotherapy with or without surgical intervention. Physiotherapy intervention often will include strengthening/stretching programmes, exercise/activity advice, and, in some centres, will include intervention, such as hydrotherapy. There is significant variation in care with no consensus on which treatment option is best. The importance of work in this area has been demonstrated by the British Society for Children’s Orthopaedic Surgery through the James Lind Alliance’s prioritization of work to determine/identify surgical versus non-surgical management of Perthes’ disease. It was identified as the fourth-highest priority for paediatric lower limb surgery research in 2018.

Methods

Five UK NHS centres, including those from the NEWS (North, East, West and South Yorkshire) orthopaedic group, contributed to this case review, with each entre providing clinical data from a minimum of five children. Information regarding both orthopaedic and physiotherapeutic management over a two-year post-diagnosis period was reviewed.

Aims

To assess if congenital foot deformity is a risk factor for developmental dysplasia of the hip (DDH).

Methods

Between 1996 and 2012, 60,844 children were born in Sør-Trøndelag county in Norway. In this cohort study, children with risk factors for DDH were examined using ultrasound. The risk factors evaluated were clinical hip instability, breech delivery, a family history of DDH, a foot deformity, and some syndromes. As the aim of the study was to examine the risk for DDH and foot deformity in the general population, children with syndromes were excluded. The information has been prospectively registered and retrospectively analyzed.

Aims

Though the pathogenesis of Legg-Calve-Perthes disease (LCPD) is unknown, repetitive microtrauma resulting in deformity has been postulated. The purpose of this study is to trial a novel upright MRI scanner, to determine whether any deformation occurs in femoral heads affected by LCPD with weightbearing.

Methods

Children affected by LCPD were recruited for analysis. Children received both standing weightbearing and supine scans in the MROpen upright MRI scanner, for coronal T1 GFE sequences, both hips in field of view. Parameters of femoral head height, width, and lateral extrusion of affected and unaffected hips were assessed by two independent raters, repeated at a one month interval. Inter- and intraclass correlation coefficients were determined. Standing and supine measurements were compared for each femoral head.


Aims

Torus fractures of the distal radius are the most common fractures in children. The NICE non-complex fracture guidelines recently concluded that bandaging was probably the optimal treatment for these injuries. However, across the UK current treatment varies widely due to a lack of evidence underpinning the guidelines. The Forearm Fracture Recovery in Children Evaluation (FORCE) trial evaluates the effect of a soft bandage and immediate discharge compared with rigid immobilization.

Methods

FORCE is a multicentre, parallel group randomized controlled equivalence trial. The primary outcome is the Wong-Baker FACES pain score at three days after randomization and the primary analysis of this outcome will use a multivariate linear regression model to compare the two groups. Secondary outcomes are measured at one and seven days, and three and six-weeks post-randomization and include the Patient Reported Outcome Measurement Information System (PROMIS) upper extremity limb score, EuroQoL EQ-5D-Y, analgesia use, school absence, complications, and healthcare resource use. The planned statistical and health economic analyses for this trial are described here. The FORCE trial protocol has been published separately.

Aims

To monitor the performance of services for developmental dysplasia of the hip (DDH) in Northern Ireland and identify potential improvements to enhance quality of service and plan for the future.

Methods

This was a prospective observational study, involving all infants treated for DDH between 2011 and 2017. Children underwent clinical assessment and radiological investigation as per the regional surveillance policy. The regional radiology data was interrogated to quantify the use of ultrasound and ionizing radiation for this population.


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.

Aims

This study sought to estimate the clinical outcomes and describe the nationwide variation in practice, as part of the feasibility workup for a National Institute for Health and Care Excellence (NICE) recommended randomized clinical trial to determine the optimal treatment of torus fractures of the distal radius in children.

Methods

Prospective data collection on torus fractures presenting to our emergency department. Patient consent and study information, including a copy of the Wong-Baker Faces pain score, was issued at the first patient contact. An automated text message service recorded pain scores at days 0, 3, 7, 21, and 42 postinjury. A cross-sectional survey of current accident and emergency practice in the UK was also undertaken to gauge current practice following the publication of NICE guidance.

Aims

The Ponseti method is an effective evidence-based treatment for clubfoot. It uses gentle manipulation to adjust the position of the foot in serial treatments towards a more physiological position. Casting is used to hold the newly achieved position. At first, the foot resists the new position imposed by the plaster cast, pressing against the cast, but over time the tissues are expected to adapt to the new position and the force decreases. The aim of this study was to test this hypothesis by measuring the forces between a clubfoot and the cast during treatment with the Ponseti method.

Patients and Methods

Force measurements were made during the treatment of ten idiopathic clubfeet. The mean age of the patients was seven days (2 to 30); there were nine boys and one girl. Force data were collected for several weeks at the location of the first metatarsal and the talar neck to determine the adaptation rate of the clubfoot.

Purpose

This 20-year prospective longitudinal observational study aims to determine the incidence of pathological developmental dysplasia of the hip (DDH) in children referred with clicky hips and define the risk posed to inform neonatal hip screening programmes including the role of ultrasound.

Method

355 children from 1997 to 2016 were referred with clicky hips to our “one stop” paediatric hip clinic under the local neonatal hip screening programme. Hips were assessed clinically for instability and by ultrasound using a simplified Graf classification. Dislocated or dislocatable hips were classed as Graf type IV.

Purpose

To determine (i) the relationship between osteonecrosis and hip function, physical function and quality of life in adolescents and young adults treated for DDH; and (ii) how affected children change over 10 years.

Methods

We included 109 patients (mean age 19.2 ± 3.8 years) with osteonecrosis and 30 age-matched patients without osteonecrosis following DDH treatment between 1992–2005. All completed valid patient-reported outcome measures to quantify their hip function (maximum score 100); physical function (maximum score 100); and quality of life (maximum score 1). Of these, 39 patients had been followed prospectively since 2006, allowing quantification of within-person changes over time.

We graded all radiographs for severity of osteonecrosis, residual dysplasia, subluxation and osteoarthritis. We determined the association between patient-reported outcomes and radiographic severity of osteonecrosis using mixed-effects regression analysis; and repeated-measures analysis of variance to quantify person changes over time. We adjusted for age, prior operations and acetabular dysplasia.

Purpose

This study compares outcomes in patients with complete congenital fibula absence, associated with severe lower limb deformity, treated with an amputation protocol to those using an extension prosthesis.

Method

32 patients were identified. 9 patients (2M: 7F, median age at presentation of 22 yrs) utilized an extension prosthesis. 23 patients (16M: 7F, median age at presentation of 10 months) underwent 25 amputations during childhood: only two underwent tibial kyphus correction to facilitate prosthetic wear.

Mobility was assessed using the SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. Patients undergoing amputation were further subdivided by age, below and above 2 yrs at the time of surgery.

Purpose

The decision to undertake prophylactic pinning to prevent contralateral slipped upper femoral epiphysis (SUFE) remains controversial; we hypothesised that the grade of initial SUFE could predict the grade of a second SUFE and risk of poor outcome.

Method

We retrospectively reviewed radiographs of all children who presented to Alder Hey with a new diagnosis of SUFE between 2007–2014. Of those who developed a contralateral SUFE, grade of first and second SUFE was determined radio-graphically using % slip and Southwick angle on frog lateral radiograph.

Purpose

To assess the use of radiographic measurement compared to descriptive classification in the evaluation of Perthes' disease.

Method

Fifteen consultant Paediatric Orthopaedic surgeons, members of the BOSS Collaborative from different UK centres, were asked to rate a series of 100 healed AP radiographs of hips affected by Perthes' Disease from the Liverpool Perthes' Disease Register using the Stulberg' s grading. Two independent observers categorised roundness error using Digitimizer™ software. Kappa scores were used to determine the inter-observer concordance amongst the 15 observers for Stulberg classification. Lin concordance was used to determine roundness error assessment. The relationship between the two outcomes was explored statistically and graphically; considering the mean Stulberg grade recorded by the 15 observers as a continuous outcome.

Purpose

There is concern that the positive predictive value (PPV) of neonatal screening for instability may have deteriorated over recent years, this study aims to evaluate this.

Method

This is a prospective observational longitudinal study from 2012 – 2016. Patients that were referred from paediatric neonatal screening with hip instability (Ortolani / Barlow positive, clunks) were identified and underwent ultrasound and clinical examination in the one stop hip clinic by the senior author. Referrals were taken from a range of screeners from paediatric doctors to midwives and advanced neonatal practitioners. Syndromic or neurological dislocated hips were excluded. The outcome measures were the presence of a subluxated / dislocated hip on ultrasound as per Graf and Harcke classification and a positive provocative manoeuvre on examination. This allowed a PPV to be evaluated for both ultrasound and clinical examination.

The treatment of developmental dysplasia of the hip (DDH) in children remains controversial, we describe the clinical and radiological outcomes of 47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH.

The mean age at operation was 25 months (5 to 113) with a mean follow up of 89 months (22 to 169).

46 hips had an anterior open reduction, 1 had a medial approach performed and 16 had anterior open reductions only. 5 of the primary operations also had a pelvic osteotomy, 7 had a femoral osteotomy and 18 had a combined femoral and pelvic osteotomy.

7 (15%) of the hips required a second operation for dislocation, subluxation or dysplasia.

At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III according to the Kalamchi and MacEwen classification) was seen in 5 (11%) of the hips.

We found a pelvic osteotomy to be a risk factor for AVN (p 0.02) and age at operation to be a risk factor for poor morphology at final follow up (p 0.03).

We proceed to open surgery in patients over 12 months old or those with failed closed reduction. Over 18 months old a pelvic osteotomy should be performed in selective cases depending on intra-operative stability, but we will now consider doing this as a staged procedure and delaying the osteotomy for a period of time after open reduction to reduce the risk of AVN. We will also have a much lower threshold for performing a femoral shortening osteotomy in these patients as open reduction with Salters osteotomy alone tended to have a poorer outcome.

The aim of our survey was to study the current practice to manage DDH in UK by the members of the British Society for Children's Orthopaedic Surgery.

An online questionnaire link to ask about the management of DDH was emailed to 204 members of the British Society for Children's Orthopaedic Surgery. The response rate was 39%. 73% respondents have a local screening programme, 19% screen only high risk children and 8% had no screening programme. Pavlik harness was used by 87% respondents for Graf Type 2, 96% for Graf type 3 and 90% for Graf type 4. 14% respondents will only observe for Graf Type 2. 36% respondents will follow up children every week, 45% every 2 weeks, 3% every 3 weeks, 9% every 4 weeks, 4% every 6 weeks and 3% will decide the follow up according to severity of DDH and treatment.1.3% respondents will follow up these patients for 6 months, 13% for 12 months, 10.5% each for 24 months, 36 months, 48 months and 50% until skeletal maturity. After the failure of initial splintage, 7% respondents will consider surgery immediately, 13.5% at 3 months, 36.5% at 6 months, 4% at 9 months, 28% at 12 months, 5.4% according to HIP-OP Trial and 5.6% according to the situation.

There was no consensus about the treatment of DDH. 73% respondents have a local screening programme. The most common splintage method used was Pavlik harness. 45% respondents will follow up children every 2 weeks following the start of treatment. 50% respondents will follow up these patients until skeletal maturity. 36% respondents will consider surgery at 6 months following the failure of splintage. This survey highlights the fact that the management of DDH is an art based on the scientific evidence, parent's choice and personal expertise.

Originally used for correction of angular malalignment, 2 hole plate epiphyseodesis has recently gained popularity in paediatric orthopaedic practice for the correction of leg length discrepancy. In this study we aim to assess the efficiency of guided growth plates in correcting leg length discrepancy

Thirty-three children treated for leg length discrepancy with guided growth plates (“8-Plate”, Orthofix, Inc and “I-Plate”, Orthopediatrics) in a tertiary referral centre were retrospectively analysed. Medial and Lateral plates were inserted for symmetrical growth reduction and patients were followed up with clinical and radiological assessment. Thirty patients had distal femoral epiphyseodesis and three had proximal tibial epiphyseodesis. Leg lengths and individual bone lengths were measured from pre and post – operative radiographs. The angle between the screws was measured from radiographs taken intra operatively and at the time of final follow up to assess screw divergence with growth. Efficiency was calculated as the ratio of growth inhibition achieved to the projected discrepancy at maturity if left untreated.

At a mean follow up of 17 months (4–30 m) leg length discrepancy improved from a mean of 30 mm (50–15mm) to 13 mm (2.5–39mm) (p < 0.01). The angle between screws increased from 6 degrees to 26 degrees over the follow up period. Efficiency was found to be 66%. There were 5 patients with angular deformity who needed plate removal and 2 patients developed superficial infection that responded to oral antibiotics.

Epiphyseodesis using guided growth plates is an effective way to correct leg length discrepancy as it is a reversible procedure. Patients undergoing this treatment should be kept under close follow up to prevent development of angular malalignment. Inserting the screws in a divergent fashion at the outset may increase the effectiveness of this procedure.

Protocol development using this unique upright MRI included healthy adult and child volunteers. Optimum patient positioning in a comparable way between supine to standing was assessed. The balance between shorter scan time (to what a child can tolerate) and longer scan time (for better image acquisition). The study protocol has begun in 2 children with LCPD. Patient recruitment continues.

Early results indicate a dynamic deformity of the femoral head in early stage LCP disease. Femoral epiphysis height decreased on standing (7.8 to 6.8mm), width increased on standing (16.6 to 20.9mm) and lateral extrusion increased (3.5 to 4.1mm). Overall epiphyseal shape changed from trapezoidal (LCP femoral head when supine) to flattened triangular (LCP femoral head when standing). Differences were thus demonstrated in all parameters of bony epiphyseal height, width, extrusion and shape of a femoral head with LCP Disease when the child stood and loaded the affected hip.

Satisfactory image acquisition was possible with Coronal T1 GFE sequences, with both hips in the Field of View. 2.5min scans were performed with the child standing first, then supine. Hip position was comparable when standing and supine. Longer scans were not tolerated by younger children, more so those with LCP disease.

To our knowledge this is the first reported use of standing MRI in LCPD. A dynamic deformity has been demonstrated, with flattening, widening and worsened lateral extrusion when the child is standing compared to supine. This proof of concept investigation demonstrates the feasibility of upright MRI scanning and may demonstrate previously undetected deformity.

This study sought to determine the genetic contribution of Perthes' disease, using the world's largest twin-registry.

We extracted all twin pairs from the Danish Twin Registry (DTR) in which at least one individual had Perthes' Disease. The DTR captures every twin pair born alive in Denmark. Those with Perthes' disease were identified using health record linkage to the Danish Morbidity Record. Probandwise concordance was calculated to describe the likelihood that any given individual had LCPD if their co-twin was also diagnosed.

There were 81 twin pairs; 10 monozygotic (MZ), 51 dizygotic (DZ), and 20 unclassified (UZ). There was no association between birth weight and being the affected co-twin. Four pairs (two dizygotic and two unclassified) were concordant for LCPD, which is greater than would be expected assuming no familial aggregation. There were no concordant MZ twin pairs. The overall probandwise concordance was 0.09 (95% CI 0.01–0.18): 0.00 for the MZ, 0.08 (95% CI 0.00–0.18) for the DZ, and 0.18 (95% 0.00–0.40) for the UZ twin pairs.

This study found evidence of familial clustering in LCPD but did not demonstrate a genetic component. The absolute risk that a co-twin of an affected individual will develop LCPD is low, even in the case of MZ twin pairs.

We present the long term outcome from children with Legg-Calves-Perthes (LCPD) treated at our unit.

Patients treated for LCPD were identified retrospectively from an orthopaedic database between 1990 and 2005. Patient demographics, clinical examination, treatment and Herring classification were recorded at initial presentation and treatment. Long-term clinical and radiological follow-up was also recorded.

85 patients were identified and 4 excluded due to insufficient data giving a total of 81 patients. Of these, 58 were male and 23 female. Average age range at presentation was 6.5 years (range 1.5–14 yrs). The side affected was 34 right, 35 left, 24 bilateral giving 93 hips in total. Time between presentation and diagnosis averaged 4.7 months (range 0–48 months). In patients with recorded clinical examination 87% had reduced abduction and 88% reduced internal rotation. Treatment was largely conservative with 12 hips (13%) undergoing surgery within the first 4 years of diagnosis. Radiographs were available for 71 hips. Herring classification was A-12, B-22, C-37. Long term follow up averaged 16 years (range 10–25 yrs). Stulberg grading was available in 67 hips; Grade I 13, Grade II 21, Grade III 19, Grade IV 18 and Grade V 6. There were ongoing issues (mostly pain) in 18 hips, 5 of which required a subsequent operation.

No correlation was found between abduction and Stulberg grade (p-value = 0.7). A correlation was found between delay in diagnosis of ≥6 months and the need for a subsequent operation (p-value = 0.0408).

The overall trend as expected showed that a better Herring classification generally led to a more favourable Stulberg classification. Range of motion was not predictive for Stulberg grade.

The need for further surgical intervention for symptoms at long term follow up was 0.05%.

To evaluate the safety and efficacy of treating patients with Graf IIa developmental hip dysplasia.

The management of the developmentally immature Graf Type IIa dysplastic hip is controversial. Some authors advocate early treatment with an abduction harness whilst others adopt watchful waiting.

At our institution selective sonographic assessment for developmental dysplasia of the hip (DDH) was established in 1997 with prospective data collection. All infants diagnosed with Graf Type IIa hip(s) were treated with either a Pavlik harness or double nappies, with clinical and sonographic follow up until normalisation. Pelvic radiographs were routinely performed at 8 and 18 months follow up for assessment of residual dysplasia and/or complications of treatment. We evaluated the safety and efficacy of all treated patients between 2005 and 2013.

Complete clinical and radiological follow up (mean 2.1 years, 0.7–6.5) was available for 103 of 118 infants. 69 were treated with a Pavlik harness and 49 with double nappies. The chosen treatment was successful in 110 hips with no documented complications, well developed ossific nuclei on follow up radiographs, and no further treatments undertaken. In the double nappy group 4 infants deteriorated sonographically so were changed to a Pavlik harness with subsequent normalisation and successful treatment.

3 patients required VDRO at age 18 months (17–20) and 1 patient required closed reduction and spica cast treatment at age 11 months. No further complications arose in this group. The 15 patients lost to follow up had successful initial treatment but failed to attend for radiographic review.

Both Pavlik harness and double nappies are safe treatment modalities for Type IIa hip dysplasia. However, sonographic deterioration was observed in both groups with surgical intervention required in the minority, supporting the ongoing treatment of these immature hips.

The aim was to assess the value of the GP 6–8 week hip examination.

In a 15-year prospective observational longitudinal cohort study, every infant referred by the GP with suspected pathological developmental dysplasia of the hip (DDH) had their hip joints clinically and sonographically examined in a specialist hip screening clinic. Graf Type IV and dislocated hips were classified as pathological. Screening failures were defined as those who had not been identified by the 6–8 week check and presented with late instability. Secondary univariate and multivariable analysis was performed to determine which clinical findings are predictive of instability.

64,518 infants underwent the 6–8 week GP check. Of 176 referrals, 5 had pathological hips. 13 screening failures, presented between the ages of 17 and 80 weeks. The 6–8 week check has a sensitivity of 28% and a specificity of 99.7%.

Univariate analysis revealed positive Ortolani tests and patients referred as ‘unstable hip’ to be significant predictors of hip pathology. Clicky hips, asymmetric skin creases, and leg length inequality were not predictive of pathological hips. A multivariable model showed a positive Ortolani test to be the sole independent predictor of instability at 6–8 weeks.

This is the first attempt to test the validity of the 6–8 week GP clinical hip check. A low rate of hip pathology was identified. The high rate of false negatives raises questions about the value of screening at this age. At 6–8 weeks, clinical signs of hip instability are unreliable as hips become irreducible and stiff.

Based on our findings, we recommend that at 6–8 weeks, referrals are only made if the Ortolani test is positive. We advocate the reintroduction of the 8-month check, including an assessment for limited hip abduction, which may improve the detection rate of those missed by initial screening.

The aim of this study was determine if the detection of pathology in children with a limp can be optimised by screening with blood tests for raised inflammatory markers.

The entry criteria for the study were children (0–15 years) presenting to our hospital Emergency Department from 2012–2015 with a non-traumatic limp or pseudoparalysis of a limb, and no sign of fracture or malignancy on plain radiographs. ESR and CRP blood tests were performed along with other standard investigations. Children with ESR or CRP over 10 underwent MRI scan of their area of pain or tendernesss, with those under 7 years old having general anaesthetic. MRI provided the diagnosis in cases of osteomyelitis, pyomyositis, fasciitis, cellulitis, discitis, as well as non-infective conditions such as malignancy and fracture not visible on plain radiographs. Where a joint effusion was present, the diagnosis of septic arthritis was made from organisms cultured following surgical drainage, or high white cell count in joint fluid if no organisms were cultured. The study was completed once data from 100 consecutive children was available.

64% of children had an infective cause for their symptoms (osteomyelitis, septic arthritis, pyomyositis, fasciitis, cellulitis or discitis). A further 11% had positive findings on MRI from non-infective causes (juvenile idiopathic arthritis, cancer, or occult fracture). The remaining 25% had either a normal scan, or transient synovitis. ESR was a more sensitive marker than CRP, since ESR was raised in 97% of those with abnormal scans, but CRP in only 70%. There were no complications from any of the GA MRI scans. Conclusion: This shows that MRI imaging of all children with a limp and either raised ESR or CRP is a sensitive method to minimise the chance of missing important pathology in this group, and is not wasteful of MRI resources.

The aim was to determine reliability in treatment threshold based on USS angular measurements between observers involved in the DDH hip screening programme at the NOC and assess the effect of image orientation on the accuracy of these measurements.

3 independent observers measured alpha and beta angles on bilateral hips in 10 consecutive patients seen in the DDH hip screening clinic. All scans were performed by a single radiographer and observers used the same set of USS images for a given patient. Each observer measured alpha and beta angles a total of 4 times: conventional ultrasound image projection (with the ilium horizontal) (round 1), Graf's anatomical projection (round 2), and both techniques repeated 1 month later (round 3 and 4 respectively) to assess intra-observer reliability. To determine its effect on treatment threshold taking into account alpha and beta angles and patient's age, the consistency between observers' management recommendations was evaluated for each round. Possible outcomes were: 1) patient discharged, 2) no treatment needed yet, but follow-up required, 3) start treatment.

Intra-observer reliability for conventional projection was moderate (Kappa 0.58), and improved for anatomical projection (Kappa 0.65). Inter-observer reliability, as a surrogate measure of consistency in management recommendations between observers, ranged from fair to moderate across the 4 rounds (Kappa 0.30 – 0.50). However, contrary to previous recommendations, reliability was better with conventional projection (Kappa 0.41 (95% CI 0.11–0.72)) compared to anatomical projection (Kappa 0.36 (95% CI −0.01–0.73)). The overall agreement in management recommendations, pooling all results across 4 rounds, was 51.3% (Kappa 0.39 (95%CI 0.15–0.63)).

This audit supports the argument that anatomical image projection improves intra-observer consistency. However, as with all USS measurements, angular measurements were highly user dependent and treatment threshold based on USS may not be as consistent as anticipated.

To evaluate effectiveness and safety of acute ulnar lengthening osteotomy in Madelung's deformity associated with Hereditary Multiple Exostoses (HME)

Seventeen ulnas in 13 patients had acute ulnar lengthening for HME associated forearm deformity. Defined radiographic parameters were compared pre- and post-operatively using student's t-test; ulnar variance, carpal slip, radial bowing, radial articular angle. All complications were noted.

Mean follow-up was 27 months (range 1.5 – 72months). An increase in ulna length by a mean of 15.4mm (range 4.5 – 29.3mm) was achieved acutely, corresponding to an increase of 9.3% of total ulnar length. Negative ulnar variance was improved from a pre-operative mean of 12.4mm (range 6.1–16.5mm) to a post-operative mean of 4.6mm (range 0–11.25mm) (p=<0.00001). Carpal slip was significantly improved by a mean of 2.2mm (p=0.02). No significant change in radial bowing (p=0.98) or radial articular angle (p=0.74) was observed. Inter-rater reliability was excellent (r=0.96, Pearson Correlation).

Three patients required second procedures for recurrence of deformity at 18 months – 6 years following their primary operation. There were no incidences of compartment syndrome, neurovascular injury nor infection. One ulna fractured intra-operatively requiring a longer plate. One patient had a non union which united on revision surgery.

Significant radiographic improvements in forearm and wrist alignment were seen with acute ulnar lengthening. The procedure is safe, with no compartment syndrome nor neurovascular injury and low complications rate. Recurrence rates in the skeletally immature patients are comparable to that reported with gradual lengthening. Acute ulnar lengthening for forearm deformity associated with HME has been demonstrated to be a safe, reproducible and effective surgical procedure.

To evaluate the outcome of combined tibialis anterior tendon shortening (TATS) and calf muscle-tendon lengthening (CMTL) in spastic equinus.

Prospectively collected data was analysed in 26 patients with hemiplegic (n=13) and diplegic (n=13) cerebral palsy (CP) (GMFCS level I or II, 14 males, 12 females, age range 10–35 years; mean 16.8 years). None had received botulinum toxin A injections or surgery in the preceding six and 12 months respectively. All patients had pre-operative 3D gait analysis and a further analysis at a mean of 17.1 months (± 5.6months) after surgery. None was lost to follow-up. Twenty-eight combined TATS and CMTL were undertaken and 19 nineteen patients had additional synchronous multilevel surgery. At follow-up 79% of patients had improved foot positioning at initial contact. Statistically significant improvements were seen in the Movement Analysis Profile for ankle dorsi-/plantarflexion (4.25, p=0.032), maximum ankle dorsiflexion during swing phase (11.68°, p<0.001), and Edinburgh Visual Gait Score (EVGS) (4.85, p=0.014). Diplegic patients had a greater improvement in the EVGS than hemiplegics (6.27 -vs- 2.21, p = 0.024).

The originators of combined TATS and CMTL showed that it improved foot positioning during gait. The present study has independently confirmed favourable outcomes in a similar patient population and added additional outcome measures, the EVGS, foot positioning at initial contact, and maximum ankle dorsiflexion during swing phase. Study limitations include short term follow-up in a heterogeneous population and that 19 patients had additional surgery. However, distinguishing between the natural history of CP and interventions and isolating the effects of one intervention from others in multilevel surgery are well recognised difficulties in cohort studies in CP. TATS combined with CMTL is a recommended option for spastic equinus in ambulatory patients with CP.

Due to abnormal neuromuscular development, functional capability in children with cerebral palsy is often severely compromised. Single event multi-level surgery (SEMLS) is the gold standard surgical treatment for patients with cerebral palsy. It has been demonstrated to improve gait, however, how standing posture is affected is unknown.

The aim was to investigate the effect of SEMLS in patients with spastic cerebral palsy on walking and standing posture using 3D gait analysis.

Participants were identified from the One Small Step Gait Laboratory database. Standardised 3D-Gait analysis was performed within 2 years pre- and post-SEMLS. Gait abnormality was measured using the Gait Profile Score (GPS) index; standing abnormality was measured using the newly-developed Standing Profile Score (SPS) index. A control group (n=20) of age/sex-matched CP patients who did not undergo surgery were also assessed.

104 patients (73 boys, 31 girls) with spastic cerebral palsy underwent SEMLS with appropriate pre- and post-gait analyses (2000–2015). 91 patients had bilateral limb involvement, 14 had unilateral limb involvement. Average age at surgery was 10.38 years (range 4.85–15.60 years). A total of 341 procedures were performed, with hamstring and gastrocnemius lengthening representing approximately 65% of this.

There was a 20% mean improvement in walking (GPS reduced 2.4°, p<0.001) and standing (SPS reduced 3.4°, p<0.001) following SEMLS. No improvement was noted in the control group. Significant correlations were observed between the changes in SPS and GPS following surgery (r2, p<0.001). Patients with poorer pre-operative standing posture (SPS) reported the most significant improvement following surgery.

We confirmed improvement in walking following SEMLS using the Gait Profile Score (GPS). This is the first paper to report that standing posture is also improved following surgery using a novel index, the Standing Posture Score (SPS). SPS could be adopted as a tool to assess functional capability and predict post-operative changes.

The aim was to examine the descriptive epidemiology of Slipped Capital Femoral Epiphysis, with respect to geography and time.

We extracted all children with a diagnosis of Slipped Capital Femoral Epiphysis from the Clinical Practice Research Database between 1990 and 2014 (24 years). CPRD is the world's largest database of primary care, which encompasses 8% of the UK population. CPRD was linked to Hospital Episode Statistics, and a validation algorithm applied to maximise sensitivity and specificity of the cases finding methodology. Poisson confidence intervals were calculated, and poison regression used.

596 cases of SCFE were identified. The internal validation algorithm supported a SCFE diagnosis in 88% cases. The age and sex distribution of cases mirrored that in the literature, offering external validity to the cases identified. There was no significant change in the incidence of SCFE over the 24-year study period, with the overall incidence being 4.8 cases per 100,00 0–16 year olds. There was no significant geographic variation in SCFE within the UK. There was a positive association with rising socioeconomic deprivation (p<0.01). There was no seasonal variation in presentation.

This study found no evidence to support the common belief that SCFE incidence is increasing, and for the first time demonstrated an association with socioeconomic deprivation. The results are important for considering the feasibility of intervention studies, and offer insights into the disease aetiology.


The study describes a technique of tibial autograft to augment posterior instrumented spinal fusion in a population of paediatric patients with severe idiopathic, neuromuscular or syndromic scoliosis who are at a higher risk of postoperative pseudarthrosis and reports patient outcomes in terms of union rate, donor site morbidity and cost.

Patients were identified from a review of waiting list and operating room records between 2007–2014. Surgery was performed by the senior author. Information on patient demographics, underlying diagnosis, age at surgery, revision surgery and length of follow-up was obtained from clinic notes. Parents of children were followed up with a structured telephone questionnaire regarding ambulatory status, post-operative pain, infection, further surgery and general satisfaction.

Four hundred and nine patients underwent posterior instrumented spinal fusion, during the study period. Forty-two patients’ fusions were augmented with tibial graft, 40 of whom participated in the study. There were no cases of donor site infection, compartment syndrome, tibial fracture or perioperative mortality. In 85% of cases leg pain had resolved within 6 weeks, and 100% within 6 months of surgery. There were 6 cases of revision spinal surgery, 3 for infection, 2 for sacroiliac screw removal and 1 for sacroiliac screw revision. There were no clinical cases of spinal pseudarthrosis in this series. All parents were satisfied by the clinical outcome of both the tibial and spinal surgeries.

Spinal fusion utilising tibial autograft is advocated as a simple, safe and cost-effective method of providing significant structural autograft to support fusion for a population of patients with high risk of junctional pseudarthrosis. With the exception of transient post-operative pain, the procedure was without any serious donor site morbidity. The outcomes of this study were as expected and in keeping with previous reports.

The aim of the study was to review the effectiveness of rigid IM nailing in stabilisation and deformity correction of lower limb long bones in adolescents with metabolic bone disease which to our knowledge has not been studied before.

Medical records and radiographs were retrospectively reviewed looking at indications, deformity correction, number of osteotomies-if needed, bone healing, time to healing and incidence of complications.

Between Aug 2010 and Mar 2015 fifteen patients (24 segments) had rigid IM nailing. Ten patients had Osteogenesis Imperfecta, four with McCune Albright syndrome and one with hypophosphatemic rickets. 22 femora and two tibiae were IM nailed. The mean age of the patients was 13.1 (9.6–16.75 years). Eleven out 24 segments were previously rodded. Eight segments were for acute fractures. 13 bones had significant deformities requiring corrective osteotomies. One patient had previous fracture non union.

All patients were allowed to partial weight bear immediately postoperatively and were fully mobile six weeks following surgery. Mean follow up was 24 months (3–51 months) post-operatively. All deformities were corrected. All fractures and osteotomies radiologically united.

Mean radiological union time was 5.5 months (6 weeks – 11 months). Patients with acute fractures had mean radiological union time of 4 months. Patients who had osteotomies had a mean radiological union time of 7.1 months. The patient with previous non union had BMP at the same time and radiologically healed in 10 months. Two patients had persistent bisphosphonate osteotomy lines but were asymptomatic. One patient had removal of a prominent distal locking screw and one had persistent Trendelenburg gait.

Rigid intramedullary nailing is effective in stabilisation and deformity correction of long bones in adolescent patients with brittle bone disease. The technique has a low complication rate. We recommend the use of this technique in paediatric limb reconstruction in managing metabolic bone conditions.

We present a review of our Specialist Physiotherapy clinic for normal physiological variations of the lower limb (SPNV) clinics, demonstrating them to be clinically effective and cost effective.

Children with normal variation of rotational profile and limb angulation present much anxiety to parents and primary care. Providing consultation: to eliminate significant pathology and reassure families, is an important service that a Paediatric Orthopaedic department provides. In our tertiary referral department we have a Specialist Physiotherapy led clinics into which primary care practitioners refer children with whom there are concerns about lower limb development variation.

The (SPNV) Clinic was first set up by a Consultant and Senior Physiotherapist in 1999. The aim of the clinic was to reduce the waiting times for incoming referrals but ensuring they are seen in an appropriate environment by an experienced health care professional. Clinics are run by Senior Specialist Physiotherapists, alongside Consultant clinics who are available for advice and direction. This provides security for the physios, the Trust and the patient.

Over 15 years there have been more than 4000 patient visits to this clinic. Over 80% were new patient visits. 70% of these visits were discharged in one or two reviews. 97.4% of new referrals were discharged without subsequent review by an orthopaedic surgeon. The most common conditions reviewed were Genu valgum (25%), Genu Varum (16%), intoeing (17%) and flexible flat feet (11%).

The clinic has proven to be cost effective as well in drawing in up to £500,000 revenue into the trust in a single year. The department has been approached by other trusts to assist in the implementation of similar clinics.

We present this review of the patients, as a template for supporting the work of Paediatric Orthopaedic Departments. This service has facilitated the streamlining of our Consultant Paediatric Orthopaedic clinics.

Purpose of the study is to investigate the outcome of the patients with Perthes disease who have had a surgical dislocation of their hip for the treatment of resultant symptoms from the disease process.

Retrospective review of consecutive patients treated with surgical dislocation of the hip for Perthes disease. Review of clinical case notes and radiological imaging. Patient outcome was assessed at follow-up.

Between 2010 and 2015, 31 cases of surgical hip dislocation were performed for Perthes disease at our institution by 2 senior surgeons. Age range at time of surgery was 12–33. Male:female ratio was 13:18; right:left ratio was 15:17. Age at the time of Perthes diagnosis was between 3 and 13 years, with 3 diagnosed retrospectively. Mean follow-up was 18months. All patients had an EUA and arthrogram while 61.3%(19/31) had previous surgery for Perthes. 71%(22/31) required a labral repair, 6.5%(2/31) had a peri-acetabular osteotomy at the time of surgery and 3.2%(1/31) required a proximal femoral valgus osteotomy. 22.5%(7/31) required microfracture (femoral head or acetabulum): all of whom had evidence of contained area of degenerative changes on preoperative MRI. 64.5%(20/31) had the trochanteric screws removed.

Complications included 1 greater trochanter non-union, 1 pain secondary to suture anchor impinging on psoas tendon, 1 AVN leading to early THR 12 months post-op. Another 2 had further deterioration of degenerative changes and pain leading to THR 18 and 24 months post-op. All 3(9.7%) had microfracture at the time of the dislocation for established degenerative change and also required custom made prostheses.

Surgical hip dislocation is an option in treating Perthes patient with resultant symptoms such as impingement. Improved outcome is seen in patients who are younger with a congruent hip joint in contrast to those with established degenerative change evident on MRI / intraoperatively and have an arrow shaped femoral head.

This study aims to evaluate the development of deformity in patients with hypophosphataemic rickets and the evolution of the orthopaedic management thereof.

Fifty-four patients had undergone treatment for hypophosphataemic rickets at our institution since 1995. Clinical records for all patients were obtained. Forty-one patients had long leg radiographs available that were analysed using Traumacad™ software. Statistical analysis was performed using SPSS 23 (SPSS Inc., Chicago, Illinois, USA).

Of the 41 patients, 18 (43%) had no radiographic deformity. 20 have undergone bilateral lower limb surgery for persistent deformity (Mechanical Axis ≥ Zone 2). A further 3 patients are awaiting surgery. Six patients (12 limbs, 14 segments) had osteotomies and internal fixation as primary intervention: only one limb developed recurrent deformity. There were no major complications.

Fourteen patients (28 limbs) had 8-plates (Orthofix, Verona) applied. In 5 limbs correction is on-going. Neutral alignment (central Zone 1) was achieved in 14/20 (70%) patients. Two patients required osteotomy and external fixation for resistant deformity. The mean rate of angular correction following 8-plate application was 0.3 and 0.7 degrees/month for the tibia and femur respectively. The mean age at 8-plate insertion was 10.25y (5–15y). Patients with more than 3 years of growth remaining responded significantly better than older patients (Fisher Exact Test, p=0.024). Guided growth was more successful in correcting valgus deformity than varus deformity (Fisher Exact Test, p=0.04). In the younger patients, diaphyseal deformity corrected as the mechanical axis improved at the rate of 0.2 and 0.7 degrees /month for the tibial and femoral shafts. Serum phosphate and alkaline phosphatase levels did not affect response to surgery or complication rate.

Guided growth by means of 8-plates is a successful in addressing deformity in hypophosphataemic rickets. Surgery is best performed in patients with more than 3 years of growth remaining.

We present the 2 year results for the first 54 patients after Selective Dorsal Rhizotomy (SDR) delivered in Bristol, concentrating on change in Reimers' migration index.

Eligible patients are selected at the SDR multidisciplinary meeting. Physiotherapy assessment is performed pre-operatively and at 6, 12 and 24 months post-surgery. Data collected includes GMFCS, Gross Motor Function Measure (GMFM) 88 and Modified Ashworth score for spasticity for major lower limb muscle groups, amongst other data. Pelvic radiographs are taken pre-operatively and at 2 years post-operatively. Reimers' migration index was measured using the hospital picture archiving and communication system (PACS).

The mean age was 7.2 (3.9–17.5) at the time of surgery. Pre- and post-operative pelvic radiographs were available for 30 patients (60 hips). 57% (n=34) hips showed an increase in migration percentage (mean 5.4%, range 0.1–17.5%) and 43% (n=26) hips showed a decrease (mean 4.0%, range 0–15.5%). Overall no significant difference was found in Reimers' migration index at 2 year follow up (mean increase 1.3% (95% CI −0.3–3.0), p=0.12).

There was an improvement in GMFCS category (by 1 grade) for 9 patients and a worsening for 1 patient at 2 year follow up. The Modified Ashworth score for spasticity improved in all patients. There was a mean improvement of 1.7 in the hip adductors and 2.4 in the ankle plantar flexors.

There was a statistically significant improvement in the GMFM 88 D and E domains of 14.7 (95% CI 11.3–18.1), p<0.0001 and 11.4 (95% CI 7.4–15.7), p<0.0001 respectively.

We found no evidence that SDR leads to worsening hip subluxation at 2 year follow up. All patients had improvement in lower limb spasticity. Overall there was a statistically significant improvement in function, as shown by GMFM 88 domains for standing, walking, running and jumping.

This study aimed to define the rates of lower limb angular correction using temporary hemiepiphysiodesis in differing skeletal pathologies.

A retrospective review of 61 children (36M:25F) with angular deformities about the knee who underwent 8-plate hemiepiphysiodesis (mean age 10.8y) was undertaken. The children were divided into 9 groups based on their underlying pathology (lower limb hypoplasia, Blount's disease, skeletal dysplasia, rickets, metabolic disease, acquired growth disturbance, vascular malformation, steroid use and complex genetic disorders). Radiographic measurements of each limb segment was undertaken using the TraumaCad® digital templating software based on standing long-leg radiographs - mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibial angle (mMPTA). The rate of correction of each parameter was calculated as a function of the time lapse between the operation date and first radiographic evidence of full correction of the mechanical axis (zone 1).

A total of 144 limb segments (80 distal femoral, 64 proximal tibial physes) were analysed. 62.5% of children had mechanical axes outside the knee joint at the time of operation; 63.2% achieved full correction. The rate of angular correction at the distal femur (mLDFA) was quickest in those with acquired growth disturbance (1.15°/month), complex genetic disorders (1.12°/month) and rickets (0.93°/month). It was slowest in those with vascular malformation (0.40°/month), lower extremity hypoplasia (0.44°/month) and metabolic disease (0.49°/month). At the proximal tibia, mMPTA correction was quickest in those with acquired growth disturbance (0.77°/month) and skeletal dysplasia (0.57°/month); whilst being slowest in those with metabolic disease (0.22°/month) and Blount's disease (0.29°/month).

The rate of angular correction about the knee varies with the underlying pathology with correction rates varying up to 3-fold. This study demonstrated the differential rate of correction of angular deformities in children with different skeletal pathologies, which would help guide the timing of hemiepiphysiodesis.

A goal attainment scale (GAS) was used to evaluate outcomes of surgical and non-surgical interventions to improve gait in children with diplegic cerebral palsy (CP).

Personal goals were recorded pre-intervention from children and/or their carers attending the Edinburgh Gait Laboratory since 2012. Twenty children underwent orthopaedic surgery (Group 1) and 25 children underwent a non-orthopaedic intervention (Group 2). Patients were excluded if the intervention was <9 months before the study period. Post-operatively children and/or their carers were contacted by telephone to complete the mGAS questionnaire, rating the achievement of goals on a 5-point scale. The majority of goals related to structure and function and were similar between groups, with goals relating to stability and lower limb structure most frequently recorded. Attaining an improvement in pain was stated more frequently by Group 1 children. The GAS formula was used to transform the composite GAS into a standardised measure (T-score) for each patient. A t-test was used to determine if the change in T-score was significantly different from 0, i.e. no change. Both groups on average achieved their goals (mean change in T-score for Group 2 11.1, vs 21.1 for Group 1). The difference between these two means was significant (p = 0.012). Additionally 16 children had undergone a follow-up gait analysis, but the relationship between the change in Gait Profile Score and GAS, assessed by Pearson's correlation coefficient was statistically insignificant.

Both surgical and non-surgical interventions enabled children to achieve their goals, although Group 1 reported higher achievement. GAS reflect patients’ aspirations and may be as relevant as post-intervention kinematic or kinetic outcomes.

Paediatric distal radial and forearm fractures account for 37.4% of all fractures in children. We present our 2.5-year results of a novel safe approach to the treatment of simple distal radial and diaphyseal fractures using intranasal diamorphine and entonox in a designated fracture reduction room in the emergency department.

All simple fractures of the distal radius and forearm admitted to our ED between March 2012 and August 2014 that could be reduced using simple manipulation techniques were included in this study. These included angulated diaphyseal fractures of the forearm, angulated metaphyseal fractures of the distal radius and Salter Harris types I and II without significant shortening. All children included were given intranasal diamorphine as well as entonox. The orthopaedic registrar on call performed all reductions.

100 children had their distal radius or forearm fracture reduced in the emergency department using entonox and diamorphine analgesia and had a same day discharge. Average age was 10 years (range 2.20–16.37 years). No complications were reported regarding the use of the analgesia and all children and parents were pleased with their treatment not requiring a hospital admission. The mean initial dorsal angulation of all fracture types was 28.05° degrees (23.91–32.23 95% CI) which was reduced to 7.03° (5.11–8.95 95% CI) post manipulation. There were 9 cases lost to follow up. Two cases lost the initial reduction of the fracture on subsequent clinic follow up and underwent internal fixation in theatre.

The use of entonox and intranasal diamorphine is a safe, effective treatment of providing adequate analgesia for children with distal radial and forearm fractures to allow manipulation of displaced dorsally angulated fractures in the emergency department. By facilitating a same day discharge, over £45,000 was saved using this safe method of treatment.

The aim was to assess the long-term impact of humeral and forearm rodding on functional ability, grip strength, joint range of motion and angular deformity in children with osteogenesis imperfecta.

A retrospective chart review was conducted on 57 children with osteogenesis imperfecta who underwent humeral rodding or forearm rodding at our institution between 1996 and 2013. Functional ability was assessed using the self-care and mobility domains of the Pediatric Evaluation and Disability Inventory (PEDI). Grip strength was measured using a dynamometer and joint range of motion with a goniometer. Deformity was measured on radiographs of the humerus or forearm. Outcomes were assessed pre-operatively and every year post-operatively. Differences between pre-operative and 1-year post-operative outcomes were compared using paired T-tests. In 44 patients with a minimum of 2 years follow-up, outcome measures at 1-year post-surgery were compared to those at the latest clinic visit (mean follow-up = 8.0 years).

Humeral and forearm rodding resulted in a significant improvement in PEDI self-care score (mean change =5.75, p=0.028 for the humerus, mean change = 6.77, p=0.0017 for the forearm) and mobility score (mean change =3.59, p=0.008 for the humerus, mean change =7.21, p=0.020 for the forearm) at 1 year post-surgery. Grip strength improved following forearm rodding (mean change = +6.13N, p=0.015) but not humeral rodding. Joint range of movement improved following humeral rodding but not forearm rodding. There was a significant improvement in radiographic angular deformity of the forearm and humerus following surgery (p<0.0001). Over 80% of improvements were maintained in the long-term.

Humeral and forearm rodding in children with osteogenesis imperfecta leads to long-term improvement in functional ability and angular deformity.

The aim was to assess the effect of caudal block on patients who have had proximal femoral &/or pelvic osteotomy compared to patients who have had epidural anaesthesia with regards to pain relief and hospital stay.

We looked at two patient cohorts; epidural & caudal pain relief in aforementioned procedures. Interrogation of our clinical database (WinDip, BlueSpeir&clinical notes) identified 57 patients: 33 proximal femoral osteotomy, 13 pelvic osteotomy and 11 combined(25 Males 32 Females), aged 1–18 years-old between 2012–2014, in two institutions. A database of demographics, operative indications, associated procedures, analgesia and type of anaesthesia was constructed in relation to daily pain score and length of hospital stay. 39 patients had epidural anaesthesia, and 18 had caudal block. Cerebral palsy with unstable hips was the commonest indication(21), followed by dysplastic hip(10), Perthes disease(8) and other causes(18). The Face, Legs, Activity, Cry, Consolability(FLACC) scale was used to assess pain.

Length of hospital stay in caudal block patients was 3.1 days(1–9), in epidural anaesthesia patients stay was 4.46 days(2–13). Paediatrics high dependency unit after an epidural was needed in 20(Average stay 3.4 days) compared to 1 who received caudal block. Caudal block FLACC pain score in the first 36 hours was 1.23(0–4) compared to 0.18(0–2) in patients who had an epidural.

Caudal block is associated with less hospital stay and fewer admissions to the high dependency unit, it also provides adequate pain relief post osteotomies when compared to epidural, therefore could be performed at units lacking epidural facilities. A change in related practice however should be cautious and supported by further studies.

The standard approach of diagnosing and monitoring scoliosis involves using the Cobb angle from posteroanterior (PA) radiograph. This approach has two key limitations: 1) It involves exposing the patients to ionising radiation during a period of heightened radiosensitivity. 2) The 2D x-ray image is a projection image of a 3D deformity and the Cobb angle represents only lateral rotation. 3DUS would overcome both these limitations.

We developed a 3DUS system by combining motion capture technology, a conventional 2D ultrasound scanner and bespoke software. An ex vivo experiment and a pilot clinical study were carried out to demonstrate the system's ability in identifying vertebrae landmarks and quantifying the curvature. For the ex vivo validation, a spine phantom was created by 3D-printing a segmented abdo-pelvis CT scan. The spine phantom was then scanned using 3DUS and the level of agreement in the dimensions measured using 3DUS and CT was assessed. An 11 year old female with adolescent idiopathic scoliosis (AIS) was scanned with 3DUS. The SP co-ordinates were projected on a plane of best-fit to compare the curvature angle from 3DUS with the Cobb angle from the x-ray image.

The spinous (SP), transverse processes and the laminae demonstrated high echogenicity and were easily identifiable. The difference between the spine phantom inter-SP dimension measurements made in 3DUS and CT was <2.5%. The PA x-ray of the AIS patient revealed 47° (L4-T11) and 52° (T6-T11) curves. 3DUS was able to represent the deformity in 3D revealing complex curvatures in all planes. The curvature angle from derived from 3DUS for the L4-T11 and T6-T11 curves were 132° (48°) and 125° (55°) respectively.

The results of this pilot study demonstrate 3DUS as a promising tool for imaging spine curvature

The study was to ascertain if parents/carers could be effective screeners in the detection of infant hip dysplasia.

Infants have been screened for developmental hip dysplasia (DDH) since the late 1960's. The recognition of the importance for early identification of the condition has been well documented. However, the changes to the national screening programme in 2008 have reduced the surveillance of DDH following the removal of the 8 month infant hip check, leaving only the 6–8 week hip check as standard.

A self-check guide for DDH has been developed to enlist parents as screeners for the condition. The guide highlights common signs used to alert to the possibility of hip dysplasia or dislocation. The guide was disseminated by the Royal Berkshire Hospital NHS Trust between 2008 – 2013 within West Berkshire through the maternity services and Health Centres. The guide provided parents with information on classic signs associated with DDH which they were asked to check for.

Of those infants referred to our specialist clinic as a result of parental screening, 73% were “abnormal” of these 33% went on to treatment with splintage. The mean age of these infants was 5.36 months. 20% of positive findings were in infants aged 7 month or over at the time seen. None went on to open surgery. These patients represented between 5 and 10% of our overall group of DDH positive patients. If left undiagnosed, they may have gone on to late presentation of hip dislocation requiring surgery as a child or undiagnosed acetabular dysplasia and possible surgical treatment in relatively early adult life.

Therefore we concluded that given the right guidance parents/carers would be ideal screeners to assist in detecting possible later presenting DDH in their baby.

The purpose of this study was to investigate whether patient age of 16 years and under is a valid “red flag” for back pain, by determining how often magnetic resonance imaging (MRI) investigations in these patients demonstrated significant pathology.

This was a retrospective review of cases over a five-year period (2008–12). The radiology database was interrogated to identify all patients aged 16 and under who had undergone an MRI scan of their lumbar spine for a primary complaint of low back pain. All emergency and inpatient admissions were excluded from the study. Casenotes of each of these patients were analysed for demographics, clinical features, diagnosis and outcome.

After exclusions, 98 eligible cases were identified. The age range of these patients was 2–16 years (mean age 12.63 years). The MRI scan found no abnormalities in 71.4% of cases. In the scans with positive findings, there were 8 cases of spondylolysis, 3 spondylolistheses, 9 cases of disc degeneration and 5 cases of Scheuermann's. Tumour or infection were found in only 3% of cases, (2 cases sacroilitis, 1 sacral chondroblastoma); there had been sacral or sacroiliac tenderness in each of these cases.

In keeping with other recent studies, this study shows that the diagnostic yield of MRI in patients under the age of 16 with low back pain is relatively high (28.6%). However, scan findings did not significantly alter management in the vast majority of cases (97%). Serious pathology (infection or tumour) was found in only 3% of cases. We therefore suggest that an age of 16 years or less, in isolation, should not be a “red flag” indicator for low back pain. We do however advise a lower threshold for imaging in patients presenting with sacral region pain and tenderness.


The aim was to compare the efficacy of selective ultrasound-screening (SUSS) for developmental dysplasia of the hip (DDH) to clinical screening alone, by comparing outcomes in a contemporary group with those from a 40 year old cohort.

This was a retrospective cohort study. The department's DDH and surgical databases were used to identify all cases of DDH, and all cases of surgery for DDH during the study period (2009–13). Patients born outside our region, and teratologic cases were excluded from analysis. The Obstetric database provided the total number of live births over the five-year period. This data was used to calculate the incidence of late-diagnosis (age over 3 months) DDH and the rate of surgery for DDH in our region. These results were compared to those of a similar study from our institution published in 1977, after the introduction of universal clinical screening. Relative risk (RR) was calculated for the two groups, and analysed for statistical significance.

The incidence of late-diagnosis DDH over the recent 5-year study period was 0.66/1000 live births, compared to 0.6/1000 in the control group. The RR for late-diagnosis DDH was not significantly different between the two groups (RR 1.14, 95% CI 0.6 to 2.2). The rate of surgery for DDH was 0.86/1000, compared to 0.9/1000 live births in the control group. The RR for surgery for DDH in the current study population compared to the historic control was 0.97, but this difference was not statistically significant (95% C.I. 0.57 to 1.68; p=0.92).

Despite advances in screening for DDH over the last 40 years, neither the incidence of late diagnosis DDH, nor rates of surgery for DDH in our region have changed. Whilst previous studies have demonstrated that SUSS does not eliminate late-presenting DDH, this study suggests it confers no advantage over clinical screening alone.

Ambulating children with bilateral spastic cerebral palsy (BSCP) demonstrate atypical posture and gait due to abnormal muscle and skeletal growth when compared to typically–developing (TD) children. Normal postural alignment in standing facilitates many of the tasks of daily living because it allows a stable base of support without requiring significant muscular effort. Similarly, increasing gait abnormality is associated with poorer functional capacity. Our aims were to compare the standing posture of TD children and children with BSCP using the Standing Profile Score and identify if any abnormality in standing is correlated with abnormality in walking in children with BSCP using the Gait Profile Score index.

We retrospectively compared 44 typically-developing children to 74 age-matched children with BSCP (GMFCS I & II). We performed 3D Gait Analysis during long-standing (10seconds) and in gait after application of 16 retro-reflective markers on anatomical landmarks of the lower limb and pelvis. Analysis of all kinematics was performed for movements in the sagittal, coronal and axial planes. The Gait Profile score (GPS) is a validated index of overall gait pathology. The Standing Profile Score (SPS) was developed using the same calculations for GPS but during static trials.

A significant correlation was observed between the Standing Profile Score (SPS) and Gait Profile Score (GPS) in children with BSCP (p<0.001). Significant differences were exhibited in GPS between the two groups, across all parameters, except the pelvic obliquity (p<0.05). A significant positive correlation existed for hip rotation in both groups, however the correlations observed at hip flexion and ankle dorsiflexion were significantly greater in the BSCP group compare to the TD group (p<0.01).

We have shown that posture during gait (GPS) is predictable from standing posture (SPS) in patients with BSCP. This biomechanical relationship can aid surgical decision-making.

The aim 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 5 case vignettes was used. Two questions examined the timing of surgery for an acute unstable SCFE in a child presenting at 6 hours and at 48 hours 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 w analysed using a chi-squared test.

The response rate was 56% (110/196). 88.2% (97/110) responded that if a child presented with an acute unstable SCFE within 6 hours, they would treat it within 24 hours of presentation, compared with 40.9% (45/110) for one presenting 48 hours after the onset of symptoms (P<0.0001). 52.6% (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 was advocated by 96.4% (106/110) and 70.9% (78/110) while corrective osteotomy was preferred by 1.8% (2/110) and 26.4% (29/110) of respondents for the mild and the severe stable slips 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 27.3% (30/110) of participants.

There are significant differences in opinions between BSCOS members as to the optimal management of SCFE in children. 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.

A femoral fracture in an adolescent is a significant injury. It is generally agreed that operative fixation is the treatment of choice and rigid intramedullary nailing is a surgical treatment option. We present on experience of treating adolescent femoral fractures using a lateral entry intramedullary nail.

We reviewed 15 femoral fractures in 13 children who we treated in our unit between 2011 and 2014. Two patients had bilateral fractures (non-simultaneous). Data collected included patient demographics, mechanism of injury, type of fracture, associated injuries, size of nail, time to unite and complications.

The mean age of the patients at time of surgery was 12 years (range 10–15). There were 7 male and 6 female. 10 fractures were caused by a fall whilst 5 were due to road traffic collisions (RTC). 8 fractures involved the middle third, 2 of theses were open fractures and were caused by a RTC. The remaining 7 involved the proximal third of the femur. The mean time to radiological union was 3.4 months (range 2.5–5) in 14 fractures. One patient had a delayed union that required bone grafting and united fully at 7.5 months post injury. The only other complications were a broken proximal locking screw in one patient and an undisplaced femoral neck fracture in another patient. These complications did not compromise the outcome. No patients had infection or developed avascular necroses at the latest follow up.

Intramedullary nailing of adolescent femoral fractures using the lateral entry point is safe and effective

A retrospective review of patients with spinal growing rods in a single institution. Demographic data including age at first surgery, diagnosis, pre- and post-operative cobb angles from erect standardised radiographs were collected. The type of construct used i.e. spine to rib or spine to spine was noted along with the type of growing mechanism used (magnetic or cassette). Any complications were collated for each technique.

Our results include 26 patients who had growing rod insertion, 12 in the spine - spine group and 14 in rib - spine group. Pre-operative cobb angles of 71 and 78 degrees respectively with a correction to 36 and 35 degrees. Mean age at surgery was 63 months in spine to spine group and 67 months in rib to spine group. Spine to spine group had 2 proximal pull out of hooks and the rib spine group had one pull out of hook.

The correction achieved by the new technique is comparable to the spine – spine constructs. Complications are seen in both groups. The perceived benefit of the new technique is the proximal spine is not violated so there is a reduced risk of mass fusion. The canal and pedicles are not included proximally, so there will be no effect on the growing diameter of the canal. Biomechanically the construct is more robust and should allow greater control of the curve. Further follow up and analysis of this new technique is warranted.

The purpose of the study was to investigate the incidence of surgical site infection following elective paediatric orthopaedic surgery.

A pro forma adopted from a pilot study was filled out preoperatively for each elective operation performed during the study period. Each patient was then followed up for six weeks postoperatively to record any SSI that developed. Data collected included patient demographics, type of operation, grade of Surgeon, type of procedure, wound length, skin preparations, use of tourniquet, any antibiotic prophylaxis and length of operation.

This study collated data on 334 operations with 410 procedural sites over a six month period. Infection were recorded in 19 sites equivalent to a SSI rate of 4.63%. None of the patients developed long-term complications.

The mean age of the participants in the study was 11 years (range 0.5 to 17 years), 57% were males and 43% were females.

The infection were detected between 1 and 38 days after surgery. The outcome was not compromised in any of the patients as none of them required long-term treatment. Statistical analysis was undertaken.

The study proves that the surgical site infection after elective paediatric orthopaedic surgery is low and serve as a bases for consenting patients for surgery.

This retrospective matched cohort study tested the hypothesis that an incomplete periacetabular acetabuloplasty, as an added step to delayed open reduction, diminishes the risk of developing acetabular dysplasia.

29 hips from 23 patients with idiopathic DDH that underwent intentionally delayed open reduction and acetabuloplasty at our institution from 2003 to 2010 were matched for age at presentation and bilaterality to historic controls. These were 29 hips from 26 patients, treated with open reduction alone from 1989 to 2003. Residual dysplasia treated with pelvic osteotomy, AVN grade II-IV, and rate of re-intervention were the outcome measures.

The mean ages at diagnosis and at surgery were 8.62 weeks and 12.97 months, respectively. At latest follow-up, 27 hips in the acetabuloplasty group and 22 in the open reduction alone group had satisfactory radiographic outcome (Severin class Ia, Ib or II) (p=0.16). 18 of the 58 hips (31.0%) had AVN, 7 (24.14%) in the case group and 11(37.93%) in the control group. Further surgery was required in 15 of the 29 hips in the open reduction alone group. These included 2 revision of open reductions, 5 pelvic osteotomies, 3 varus derotation osteotomies, and 5 apo or epiphysiodesis whilst only one patient in the acetabuloplasty group required a medial screw epiphysiodesis for late lateral growth arrest. There is a positive association between the need for further surgery and open reductions alone: the odds ratio is 14.00 and the 95% confidence interval (1.97, 99.63), p=0.0017. The five hips in the open reduction alone group that required a pelvic osteotomy were intervened at an average of 31.45 (±9.07) months.

The addition of an incomplete periacetabular periacetabuloplasty to all hips undergoing open reduction eliminated residual acetabular dysplasia in this cohort whilst it does not appear to have deleterious effects, as evidenced by the similar Severin and McKay scores.

The purpose of the study was to identify risk factors that are associated with re-displacement of the hip after surgical reconstruction in cerebral palsy.

Retrospective review of children with cerebral palsy who had hip reconstruction with proximal femoral varus derotation osteotomy (VDRO) and Dega-type pelvic osteotomy, between 2005–2012, at a UK and European institution, was performed. Patient demographics, GMFCS, clinical and radiological outcome were assessed as well as the presence of pelvic obliquity and significant scoliosis (Cobb angle > 10 degrees). Redisplacement was defined as Reimer's Migration Index (MI) >30% at final follow-up. Logistic regression analysis was used to assess which factors were predictive of redisplacement and adjusted for clustered variables (α = 0.05).

Eighty hips were identified in 61 patients. The mean age at surgery was 8.8 years (± 3.3). Mean MI pre-op was 68% (± 23%) and post-op was 8% (± 12%). At a mean follow-up, of 3.2 years (± 2.0), 23 hips had a MI >30%. Of these; five were symptomatic, and one had required a salvage procedure. Metalwork removal was undertaken in 14 hips. Logistic regression demonstrated that the pre-operative MI and the percentage of acute correction were significant predictors of re-displacement. If the pre-operative MI was greater than 65 percent, the odds ratio (OR) for redisplacement was 5.99 (p = 0.04). If correction of the MI was less than 90% of the pre-operative MI, the OR for re-displacement was 4.6 (p = 0.03). Age at the time of surgery, GMFCS, pelvic obliquity and scoliosis were not predictive of re-displacement.

These results, firstly, highlight the importance of hip surveillance in children with cerebral palsy to allow timely intervention to ensure adequate radiological outcomes. Secondly, as in developmental hip dysplasia, full concentric reduction is essential to reduce the risk of re-displacement, with its associated clinical consequences.
