Purpose of study. The results clinically & statistically of a 14 year longitudinal study comparing the traditional ‘stretch & strap’ method (1994-2002) with the Ponseti technique (2002-2008). Methods & Results. A 14 year prospective longitudinal comparative study was undertaken into management and outcome of CTEV. There were 114 feet (80 patients), 64 feet (45 patients) treated traditionally and 50 feet (35 Patients) with the Ponseti technique. Patient demographics, the Harold & Walker Classification, and associated risk factors for CTEV were analysed. If conservative treatment failed a radical sub-talar release operation (RSR) was undertaken. The incidence of fixed CTEV was 1.6 per 1000 live births with a male to female ratio of 2.8 to 1. Idiopathic CTEV was present in 77.5% of patients, (22.5% with a primary aetiology). Mean time to RSR was comparable: 37.43 weeks (CI: 33.65 to 41.21) and 46 weeks (CI: 39.18 to 52.82) for the traditional and Ponseti groups respectively. In the traditional group 65.6% (CI: 53.4 to 76.1%) of feet underwent RSR surgery compared to just 25.5% (CI: 15.8 to 38.3%) in the Ponseti group, When idiopathic CTEV was analysed separately these rates reduce to 56.5% (CI: 42.3 to 69.8%) and 15.8% (CI: 7.4 to 30.4%) respectively. The Relative Risk of requiring RSR surgery in traditional compared to Ponseti groups was 2.58 (CI: 1.59 to 4.19) for all patients and 3.58 (CI: 1.65 to 7.78) for idiopathic CTEV (statistically significant). The results of the Ponseti method improved with time suggesting a learning curve. Conclusion. In this study, the Ponseti technique has significantly reduced the need for RSR surgery in fixed CTEV

Aim:. An assessment of the relationship between pathological Developmental Dysplasia of the Hip (DDH) and Congenital Talipes Equinovarus (CTEV). Introduction:. Traditional UK guidelines consider abnormalities of the foot to be a risk factor for DDH. 1,2. Currently, there is controversy whether congenital foot abnormalities are true risk factors for pathological DDH. 3,4. There is a relationship between CTCV and hip dysplasia though the relationship between CTEV and pathological DDH is less clear. 5. In a previous 11 year prospective longitudinal study no case of Graf Types III, IV or irreducible hip dislocation were associated with CTEV. 5. Subsequent correspondence and case histories have challenged this view. 6. Methods:. In order to clarify this issue, a 20-year prospective longitudinal observational study was undertaken. All cases of fixed CTEV (Harold & Walker types 1 to 3) referred to the sub-regional Paediatric Orthopaedic clinic at the Royal Blackburn Hospital were evaluated, the feet and hips clinically assessed (Ortolani & Barlow manoeuvres) and the hips ultra-sounded by the senior author (RWP). Modified Graf and Harcke hip ultrasound classification systems were employed. Graf Type III, IV and irreducible hip dislocation were considered pathological. Results:. The incidence of CTEV was 1.46 per 1000 live births (nationally quoted incidence of 1 to 2 per 1000 live births. 7. ). There was one case of Graf Type III dysplasia with no cases of clinical hip instability. Currently, the clinical significance of this type of dysplasia is uncertain. There were no cases of Graf Type IV dislocations or radiological irreducible hip dislocation. Conclusion:. Fixed CTEV should not be considered as a risk factor for pathological DDH and routine sonographic hip screening of CTEV should not be advocated. This is supportive evidence for the current English NIPE guidelines in which the only risk factors screened are family history and breech presentation. Level of evidence: II

Permanent growth arrest of the longer bone is an option in the treatment of minor leg-length discrepancies. The use of a tension band plating technique to produce a temporary epiphysiodesis is appealing as it avoids the need for accurate timing of the procedure in relation to remaining growth. We performed an animal study to establish if control of growth in a long bone is possible with tension band plating. Animals (pigs) were randomised to temporary epiphysiodesis on either the right or left tibia. Implants were removed after ten weeks. Both tibiae were examined using MRI at baseline, and after ten and 15 weeks. The median interphyseal distance was significantly shorter on the treated tibiae after both ten weeks (p = 0.04) and 15 weeks (p = 0.04). On T₁-weighted images the metaphyseal water content was significantly reduced after ten weeks on the treated side (p = 0.04) but returned to values comparable with the untreated side at 15 weeks (p = 0.14). Return of growth was observed in all animals after removal of implants.

Temporary epiphysiodesis can be obtained using tension band plating. The technique is not yet in common clinical practice but might avoid the need for the accurate timing of epiphysiodesis.

Purpose

To clarify the true association with pathological DDH and ASC (asymmetrical skin crease).

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. Results. Of 993 infants assessed clinically and sonographically, 21% (212 infants, 354 abnormal hips) had DDH and were included. Of these, 95% (202 infants, 335 hips) successfully completed bracing, and 5% (ten infants, 19 hips) failed bracing due to irreducible hip(s). The success rate of bracing for unilateral dislocations was 88% (45/51 infants) and for bilateral dislocations 83% (20/24 infants). The femoral nerve palsy rate was 1% (2/212 infants). At five-year follow-up (mean 63 months (SD 5.9; 49 to 83)) the prevalence of residual dysplasia after successful brace treatment was 1.6% (5/312 hips). All hips were IHDI grade I and none had AVN. Four children (4/186; 2%) subsequently underwent surgery for residual dysplasia. Conclusion. Our comprehensive protocol for nonoperative treatment of infant DDH has shown high rates of success and extremely low rates of residual dysplasia at a mean age of five years.

Aims. Radiological residual acetabular dysplasia (RAD) has been reported in up to 30% of children who had successful brace treatment of infant developmental dysplasia of the hip (DDH). Predicting those who will resolve and those who may need corrective surgery is important to optimize follow-up protocols. In this study we have aimed to identify the prevalence and predictors of RAD at two years and five years post-bracing. Methods. This was a single-centre, prospective longitudinal cohort study of infants with DDH managed using a published, standardized Pavlik harness protocol between January 2012 and December 2016. RAD was measured at two years’ mean follow-up using acetabular index-lateral edge (AI-L) and acetabular index-sourcil (AI-S), and at five years using AI-L, AI-S, centre-edge angle (CEA), and acetabular depth ratio (ADR). Each hip was classified based on published normative values for normal, borderline (1 to 2 standard deviations (SDs)), or dysplastic (> 2 SDs) based on sex, age, and laterality. Results. Of 202 infants who completed the protocol, 181 (90%) had two and five years’ follow-up radiographs. At two years, in 304 initially pathological hips, the prevalence of RAD (dysplastic) was 10% and RAD (borderline) was 30%. At five years, RAD (dysplastic) decreased to 1% to 3% and RAD (borderline) decreased to < 1% to 2%. On logistic regression, no variables were predictive of RAD at two years. Only AI-L at two years was predictive of RAD at five years (p < 0.001). If both hips were normal at two years’ follow-up (n = 96), all remained normal at five years. In those with bilateral borderline hips at two years (n = 21), only two were borderline at five years, none were dysplastic. In those with either borderline-dysplastic or bilateral dysplasia at two years (n = 26), three (12%) were dysplastic at five years. Conclusion. The majority of patients with RAD at two years post-brace treatment, spontaneously resolved by five years. Therefore, children with normal radiographs at two years post-brace treatment can be discharged. Targeted follow-up for those with abnormal AI-L at two years will identify the few who may benefit from surgical correction at five years’ follow-up.

Aims

Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options.

Aims

Fixation techniques used in the treatment of slipped capital femoral epiphysis (SCFE) that allow continued growth of the femoral neck, rather than inducing epiphyseal fusion in situ, have the advantage of allowing remodelling of the deformity. The aims of this study were threefold: to assess whether the Free-Gliding (FG) SCFE screw prevents further slip; to establish whether, in practice, it enables lengthening and gliding; and to determine whether the age of the patient influences the extent of glide.

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.

Aims

Temporary hemiepiphysiodesis (HED) is applied to children and adolescents to correct angular deformities (ADs) in long bones through guided growth. Traditional Blount staples or two-hole plates are mainly used for this indication. Despite precise surgical techniques and attentive postoperative follow-up, implant-associated complications are frequently described. To address these pitfalls, a flexible staple was developed to combine the advantages of the established implants. This study provides the first results of guided growth using the new implant and compares these with the established two-hole plates and Blount staples.

Aims

The gold standard for percutaneous Achilles tendon tenotomy during the Ponseti treatment for idiopathic clubfoot is a tenotomy with a No. 15 blade. This trial aims to establish the technique where the tenotomy is performed with a large-bore needle as noninferior to the gold standard.

Aims

We investigated the prevalence of late developmental dysplasia of the hip (DDH), abduction bracing treatment, and surgical procedures performed following the implementation of universal ultrasound screening versus selective ultrasound screening programmes.

Aims. A clicky hip is a common referral for clinical and sonographic screening for developmental dysplasia of the hip (DDH). There is controversy regarding whether it represents a true risk factor for pathological DDH. Therefore a 20-year prospective, longitudinal, observational study was undertaken to assess the relationship between the presence of a neonatal clicky hip and pathological DDH. Patients and Methods. A total of 362 infants from 1997 to 2016 were referred with clicky hips to our ‘one-stop’ paediatric hip screening clinic. Hips were assessed clinically for instability and by ultrasound imaging using a simplified Graf/Harcke classification. Dislocated or dislocatable hips were classified as Graf Type IV hips. Results. The mean age at presentation was 13.8 weeks (12.8 to 14.7). In all 351 out of 362 children (97.0%) had Graf Type I hips (normal) that required no treatment. Nine children (2.5%) had Graf Type II hips but all resolved to Graf Type I hips on follow-up scans. One child (0.3%) had Graf Type III hip dysplasia and one child (0.3%) had an irreducible hip dislocation. The two pathological hips were associated with unilateral limited hip abduction. Mean referrals increased from 12.9 to 23.3 each year (p = 0.002) from the first decade of the study to the second, driven by increasing primary care referrals (5.5 versus 16.7 per year, p < 0.001). Conclusion. Most clicky hips required no treatment other than reassurance to parents. Clicky hips with a normal hip examination should be considered a variant of normal childhood and not a risk factor for DDH. However, an abnormal hip examination including unilateral limited hip abduction should prompt urgent further investigations. Cite this article: Bone Joint J 2017;99-B:1533–6

Aims

Osteofibrous dysplasia (OFD) is a rare benign lesion predominantly affecting the tibia in children. Its potential link to adamantinoma has influenced management. This international case series reviews the presentation of OFD and management approaches to improve our understanding of OFD.

The accurate assessment of skeletal maturity is essential in the management of orthopaedic conditions in the growing child. In order to identify the time of peak height velocity (PHV) in adolescents, two systems for assessing skeletal maturity have been described recently; the calcaneal apophyseal ossification method and the Sanders hand scores. . The purpose of this study was to compare these methods in assessing skeletal maturity relative to PHV. We studied the radiographs of a historical group of 94 healthy children (49 females and 45 males), who had been followed longitudinally between the ages of three and 18 years with serial radiographs and physical examination. Radiographs of the foot and hand were undertaken in these children at least annually between the ages of ten and 15 years. We reviewed 738 radiographs of the foot and 694 radiographs of the hand. PHV was calculated from measurements of height taken at the time of the radiographs. . Prior to PHV we observed four of six stages of calcaneal apophyseal ossification and two of eight Sanders stages. Calcaneal stage 3 and Sanders stage 2 was seen to occur about 0.9 years before PHV, while calcaneal stage 4 and Sanders stage 3 occurred approximately 0.5 years after PHV. . The stages of the calcaneal and Sanders systems can be used in combination, offering better assessment of skeletal maturity with respect to PHV than either system alone. .

There is controversy whether congenital foot abnormalities are true risk factors for pathological dysplasia of the hip. Previous United Kingdom screening guidelines considered congenital talipes equinovarus (CTEV) to be a risk factor for hip dysplasia, but present guidelines do not. We assessed the potential relationship between pathological dysplasia of the hip and fixed idiopathic CTEV. We present a single-centre 21-year prospective longitudinal observational study. All fixed idiopathic CTEV cases were classified (Harrold and Walker Types 1 to 3) and the hips clinically and sonographically assessed. Sonographic Graf Type III, IV and radiological irreducible hip dislocation were considered to be pathological hip dysplasia. Over 21 years there were 139 children with 199 cases of fixed idiopathic CTEV feet. Sonographically, there were 259 normal hips, 18 Graf Type II hips, 1 Graf Type III hip and 0 Graf Type IV hip. There were no cases of radiological or sonographic irreducible hip dislocation. Fixed idiopathic CTEV should not be considered as a significant risk factor for pathological hip dysplasia. This conclusion is in keeping with the current newborn and infant physical examination guidelines in which the only risk factors routinely screened are family history and breech presentation. Our findings suggest CTEV should not be considered a significant risk factor in pathological dysplasia of the hip. Cite this article: Bone Joint J 2014;96-B:1553–5

Aims

Perthes’ disease (PD) often results in femoral head deformity and leg length discrepancy (LLD). Our objective was to analyze femoral morphology in PD patients at skeletal maturity to assess where the LLD originates, and evaluate the effect of contralateral epiphysiodesis for length equalization on proximal and subtrochanteric femoral lengths.

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. Results. The mean age at presentation was 13.9 (1–56) weeks. 343 out of 355 (96.6%) were Graf type I which required no treatment. 9 (2.5%) were Graf type II but all converted to Graf type I on follow up scans. 2 (0.6%) had Graf type III dysplasia and 1 (0.3%) had irreducible dislocation but all three were associated with limited hip abduction or other hip pathology. Referrals increased from 12.9 to 22.6 per year (p=0.002) from first decade of the study to the second, driven by rising primary care referrals (5.5 vs. 16.5 per year p=0.00002). Conclusion. The study provided robust evidence that overwhelming majority of clicky hips required no treatment other than reassurance to parents. Clicky hips with normal hip examination should be considered a variant of normal childhood and not a risk factor for DDH. However clicky hips with limited hip abduction may represent a separate clinical entity at risk of hip pathology and therefore warrant further investigations

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. Results. 139 neonates were referred for a suspected dislocated or dislocatable hip from paediatric screening services. These were seen at a mean 14.0 days (95% C I, 12.28 to 15.72). 20 patients had a Graf type 4 hip on ultrasound and 5 had a positive provocative test on examination. This represents an ultrasound PPV of 14.4% and clinical exam PPV of 3.6% . This has deteriorated from 15 year data from our unit (PPV 24% clinical, 49% sonographic). Our overall surgical rate for DDH has increased to 1.07 per 1000, and our overall rate of open reductions has increased to 0.7 per 1000. This is based upon figures from 2012 – 2014. Conclusion. The PPV of screening has decreased over the last 5 years. The concern is too many screeners who, with regards screening the paediatric hip, are poorly trained, inexperienced, not adequately supervised. We need to learn the lessons of Sweden and ensure better quality screening by limiting screening to a small number of experienced practitioners

We evaluated the morphological changes to the ulnar nerve of both elbows in the cubital tunnel by sonography in a total of 237 children, of whom 117 were aged between six and seven years, 66 between eight and nine years, and 54 between ten and 11 years. We first scanned longitudinally in the extended elbow and then transversely at the medial epicondyle with the elbow extended to 0°. We repeated the scans with the elbow flexed at 45°, 90°, and 120°. There were no significant differences in the area of the ulnar nerve, but the diameter increased as the elbow moved from extension to flexion in all groups. More importantly, the ulnar nerve was subluxated anteriorly on to the medial epicondyle by 1.5% to 1.9% in extended elbows, by 5.9% to 7.9% in those flexed to 45°, by 40.0% to 44% in those flexed to 90°, and by 57.4% to 58.1% in those flexed to 120°, depending on the age group. Sonography clearly and accurately showed the ulnar nerve and was useful for localising the nerve before placing a medial pin. Because the ulnar nerve may translate anteriorly onto the medial epicondyle when the elbow is flexed to 90° or more, it should never be overlooked during percutaneous medial pinning
