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.

Aims. The aim of this study was to gain an agreement on the management of idiopathic congenital talipes equinovarus (CTEV) up to walking age in order to provide a benchmark for practitioners and guide consistent, high-quality care for children with CTEV. Methods. The consensus process followed an established Delphi approach with a predetermined degree of agreement. The process included the following steps: establishing a steering group; steering group meetings, generating statements, and checking them against the literature; a two-round Delphi survey; and final consensus meeting. The steering group members and Delphi survey participants were all British Society of Children’s Orthopaedic Surgery (BSCOS) members. Descriptive statistics were used for analysis of the Delphi survey results. The Appraisal of Guidelines for Research & Evaluation checklist was followed for reporting of the results. Results. The BSCOS-selected steering group, the steering group meetings, the Delphi survey, and the final consensus meeting all followed the pre-agreed protocol. A total of 153/243 members voted in round 1 Delphi (63%) and 132 voted in round 2 (86%). Out of 61 statements presented to round 1 Delphi, 43 reached ‘consensus in’, no statements reached ‘consensus out’, and 18 reached ‘no consensus’. Four statements were deleted and one new statement added following suggestions from round 1. Out of 15 statements presented to round 2, 12 reached ‘consensus in’, no statements reached ‘consensus out’, and three reached ‘no consensus’ and were discussed and included following the final consensus meeting. Two statements were combined for simplicity. The final consensus document includes 57 statements allocated into six successive stages. Conclusion. We have produced a consensus document for the treatment of idiopathic CTEV up to walking age. This will provide a benchmark for standard of care in the UK and will help to reduce geographical variability in treatment and outcomes. Appropriate dissemination and implementation will be key to its success. Cite this article: Bone Joint J 2022;104-B(6):758–764

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).

Aims

We aimed to determine hip-related quality of life and clinical findings following treatment for neonatal hip instability (NHI) compared with age- and sex-matched controls. We hypothesized that NHI would predispose to hip discomfort in long-term follow-up.

Aims. To analyze outcomes reported in studies of Ponseti correction of idiopathic clubfoot. Methods. A systematic review of the literature was performed to identify a list of outcomes and outcome tools reported in the literature. A total of 865 studies were screened following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and 124 trials were included in the analysis. Data extraction was completed by two researchers for each trial. Each outcome tool was assigned to one of the five core areas defined by the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT). Bias assessment was not deemed necessary for the purpose of this paper. Results. In total, 20 isolated outcomes and 16 outcome tools were identified representing five OMERACT domains. Most outcome tools were appropriately designed for children of walking age but have not been embraced in the literature. The most commonly reported isolated outcomes are subjective and qualitative. The quantitative outcomes most commonly used are ankle range of motion (ROM), foot position in standing, and muscle function. Conclusions. There is a diverse range of outcomes reported in studies of Ponseti correction of clubfoot. Until outcomes can be reported unequivocally and consistently, research in this area will be limited. Completing the process of establishing and validating COS is the much-needed next step. Cite this article: Bone Joint Open 2020;1-8:457–464

The October 2015 Children’s orthopaedics Roundup³⁶⁰ looks at: Radiographic follow-up of DDH; When the supracondylar goes wrong; Apophyseal avulsion fractures; The ‘pulled elbow’; Surgical treatment of active or aggressive aneurysmal bone cysts in children; Improving stability in supracondylar fractures; Biological reconstruction may be preferable in children’s osteosarcoma; The paediatric hip fracture

Acute angulation at the thoracolumbar junction with segmental subluxation of the spine occurring at the level above an anteriorly hypoplastic vertebra in otherwise normal children is a rare condition described as infantile developmental thoracolumbar kyphosis. Three patient series with total of 18 children have been reported in the literature. We report five children who presented with thoracolumbar kyphosis and discuss the treatment algorithm. We reviewed the medical records and spinal imaging at initial clinical presentation and at minimum two-year follow-up. The mean age at presentation was eight months (two to 12). All five children had L2 anterior vertebral body hypoplasia. The kyphosis improved spontaneously in three children kept under monitoring. In contrast, the deformity was progressive in two patients who were treated with bracing. The kyphosis and segmental subluxation corrected at latest follow-up (mean age 52 months; 48 to 60) in all patients with near complete reconstitution of the anomalous vertebra. The deformity and radiological imaging on a young child can cause anxiety to both parents and treating physicians. Diagnostic workup and treatment algorithm in the management of infantile developmental thoracolumbar kyphosis is proposed. Observation is indicated for non-progressive kyphosis and bracing if there is evidence of kyphosis and segmental subluxation deterioration beyond walking age. Surgical stabilisation of the spine can be reserved for severe progressive deformities unresponsive to conservative treatment.

The August 2014 Children’s orthopaedics Roundup³⁶⁰ looks at: Conservative treatment still OK in paediatric clavicular fractures; Femoral anteversion not the usual suspect in patellar inversion; Shoulder dislocation best treated with an operation; Perthes’ disease results in poorer quality of adult life; Physiotherapy little benefit in supracondylar fractures; Congenital vertical talus addressed at the midtarsal joint; Single-sitting DDH surgery worth the effort; and cubitus valgus associated with simple elbow dislocation

Children with congenital vertical talus (CVT) have been treated with extensive soft-tissue releases, with a high rate of complications. Recently, reverse Ponseti-type casting followed by percutaneous reduction and fixation has been described, with excellent results in separate cohorts of children with CVT, of either idiopathic or teratological aetiology. There are currently no studies that compare the outcome in these two types. We present a prospective cohort of 13 children (21 feet) with CVT of both idiopathic and teratological aetiology, in which this technique has been used. Clinical, radiological and parent-reported outcomes were obtained at a mean follow-up of 36 months (8 to 57). Six children (nine feet) had associated neuromuscular conditions or syndromes; the condition was idiopathic in seven children (12 feet).

Initial correction was achieved in all children, with significant improvement in all radiological parameters. Recurrence was seen in ten feet. Modification of the technique to include limited capsulotomy at the initial operation may reduce the risk of recurrence.

The reverse Ponseti-type technique is effective in the initial correction of CVT of both idiopathic and teratological aetiology. Recurrence is a problem in both these groups, with higher rates than first reported in the original paper. However, these rates are less than those reported after open surgical release.

The incidence of clinically significant avascular necrosis (AVN) following medial open reduction of the dislocated hip in children with developmental dysplasia of the hip (DDH) remains unknown. We performed a systematic review of the literature to identify all clinical studies reporting the results of medial open reduction surgery. A total of 14 papers reporting 734 hips met the inclusion criteria. The mean follow-up was 10.9 years (2 to 28). The rate of clinically significant AVN (types 2 to 4) was 20% (149/734). From these papers 221 hips in 174 children had sufficient information to permit more detailed analysis. The rate of AVN increased with the length of follow-up to 24% at skeletal maturity, with type 2 AVN predominating in hips after five years’ follow-up. The presence of AVN resulted in a higher incidence of an unsatisfactory outcome at skeletal maturity (55% vs 20% in hips with no AVN; p < 0.001). A higher rate of AVN was identified when surgery was performed in children aged < 12 months, and when hips were immobilised in ≥ 60°of abduction post-operatively. Multivariate analysis showed that younger age at operation, need for further surgery and post-operative hip abduction of ≥ 60° increased the risk of the development of clinically significant AVN.

Our goal was to evaluate the use of Ponseti’s method, with minor adaptations, in the treatment of idiopathic clubfeet presenting in children between five and ten years of age. A retrospective review was performed in 36 children (55 feet) with a mean age of 7.4 years (5 to 10), supplemented by digital images and video recordings of gait. There were 19 males and 17 females. The mean follow-up was 31.5 months (24 to 40). The mean number of casts was 9.5 (6 to 11), and all children required surgery, including a percutaneous tenotomy or open tendo Achillis lengthening (49%), posterior release (34.5%), posterior medial soft-tissue release (14.5%), or soft-tissue release combined with an osteotomy (2%). The mean dorsiflexion of the ankle was 9° (0° to 15°). Forefoot alignment was neutral in 28 feet (51%) or adducted (< 10°) in 20 feet (36%), > 10° in seven feet (13%). Hindfoot alignment was neutral or mild valgus in 26 feet (47%), mild varus (< 10°) in 19 feet (35%), and varus (> 10°) in ten feet (18%). Heel–toe gait was present in 38 feet (86%), and 12 (28%) exhibited weight-bearing on the lateral border (out of a total of 44 feet with gait videos available for analysis). Overt relapse was identified in nine feet (16%, six children). The parents of 27 children (75%) were completely satisfied.

A plantigrade foot was achieved in 46 feet (84%) without an extensive soft-tissue release or bony procedure, although under-correction was common, and longer-term follow-up will be required to assess the outcome.

Most centres in the United Kingdom adopt a selective screening programme for developmental dysplasia of the hip (DDH) based on repeated clinical examination and selective ultrasound examination. The Newborn Infant Physical Examination protocol implemented in 2008 recommends a first examination at birth and then a second and final examination at six to ten weeks of age. Due to concerns over an increase in late presentations we performed a retrospective review of our 15-year results to establish if late presentation increases treatment requirements. Of children presenting before six weeks of age, 84% were treated successfully with abduction bracing, whereas 86% of children presenting after ten months eventually required open reduction surgery. This equates to a 12-fold increase in relative risk of requiring open reduction following late presentation. Increasing age at presentation was associated with an increase in the number of surgical procedures, which are inevitably more extensive and complex, with a consequent increased in cost per patient. The implementation of an opportunistic examination at three to five months could help to reduce the unintended consequences of the Newborn Infant Physical Examination programme.

We describe three cases of infantile tibia vara resulting from an atraumatic slip of the proximal tibial epiphysis upon the metaphysis. There appears to be an association between this condition and severe obesity. Radiologically, the condition is characterised by a dome-shaped metaphysis, an open growth plate and disruption of the continuity between the lateral borders of the epiphysis and metaphysis, with inferomedial translation of the proximal tibial epiphysis. All patients were treated by realignment of the proximal tibia by distraction osteogenesis with an external circulator fixator, and it is suggested that this is the optimal method for correction of this complex deformity. There are differences in the radiological features and management between conventional infantile Blount’s disease and this ‘slipped upper tibial epiphysis’ variant.

The April 2012 Children’s orthopaedics Roundup³⁶⁰ looks at osteonecrosis of the femoral head and surgery for dysplasia, femoral head blood flow during surgery, femoroacetabular impingement and sport in adolescence, the Drehmann sign, a predictive algorithm for septic arthritis, ACL reconstruction and arthrofibrosis in children, spinal cord monitoring for those less than four years old, arthroereisis for the flexible flat foot, fixing the displaced lateral humeral fracture, and mobile phones and inclinometer applications

We present a systematic review of the results of the Ponseti method of management for congenital talipes equinovarus (CTEV). Our aims were to assess the method, the effects of modifications to the original method, and compare it with other similar methods of treatment. We found 308 relevant citations in the English literature up to 31 May 2010, of which 74 full-text articles met our inclusion criteria. Our results showed that the Ponseti method provides excellent results with an initial correction rate of around 90% in idiopathic feet. Non-compliance with bracing is the most common cause of relapse. The current best practice for the treatment of CTEV is the original Ponseti method, with minimal adjustments being hyperabduction of the foot in the final cast and the need for longer-term bracing up to four years. Larger comparative studies will be required if other methods are to be recommended.

We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity.

We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary.
