Aims. Osteonecrosis (ON) can cause considerable morbidity in young people who undergo treatment for acute lymphoblastic leukaemia (ALL). The aims of this study were to determine the operations undertaken for ON in this population in the UK, along with the timing of these operations and any sequential procedures that are used in different joints. We also explored the outcomes of those patients treated by core decompression (CD), and compared this with conservative management, in both the pre- or post-collapse stages of ON. Methods. UK treatment centres were contacted to obtain details regarding surgical interventions and long-term outcomes for patients who were treated for ALL and who developed ON in UKALL 2003 (the national leukaemia study which recruited patients aged 1 to 24 years at diagnosis of ALL between 2003 and 2011).

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

The aim of this study was to evaluate the correlation between
Salter’s criteria and Kalamchi’s classification of avascular necrosis
in patients treated for developmental dysphasia of the hip (DDH). The study involved a retrospective analysis of 123 patients (123
hips) with DDH treated by operative and non-operative reduction
before the age of two years, with a minimum follow-up of ten years.
Salter’s criteria (S1 to S4) were determined from radiographs obtained
at one to two years post-reduction, whilst the Kalamchi grade was determined
from radiographs obtained at ten or more years of age. Early post-reduction
radiographs were also used to evaluate the centre-head distance
discrepancy (CHDD) and the occurrence of a dome-shaped deformity
of the proximal femoral metaphysis (D-shaped metaphysis). The prognosis was described as good (Kalamchi grade K0 or KI),
fair (Kalamchi grade KII) or poor (Kalamchi grade KIII or KIV) for
analysis and correlation with the early Salter criteria, CHDD and
D-shaped metaphysis.Aims
Patients and Methods
The long term results of closed reduction of the hip for DDH were reviewed to determine if the presence of the ossific nucleus had an effect on outcome. The clinical and radiological outcome of a single-surgeon series of closed reduction for DDH was assessed in a strictly defined group of 48 hips in 42 patients with an average of 11.1 years follow up. In 50% of cases, the ossific nucleus was absent. 100% of patients had an excellent or good result (Severin classification) at final follow-up. 8.3% (4 hips) demonstrated evidence of avascular necrosis. Three were Kalamchi & MacEwen Type I and one was type II. Two of the AVN cases did not demonstrate an ossific nucleus at closed reduction, and both developed type I AVN. 6 hips underwent further surgery. The acetabular index and center-edge angle were not significantly different between the affected and unaffected hip at final follow-up. There was no relationship between the presence or absence of an ossific nucleus at the time of closed reduction and the final outcome. In this well defined group, closed reduction is safe and provides excellent results in the long-term. The absence of an ossific nucleus is not detrimental to the final outcome.

Aims. There is no consensus regarding optimum timing and frequency of ultrasound (US) for monitoring response to Pavlik harness (PH) treatment in developmental dysplasia of the hip (DDH). The purpose of our study was to determine if a limited-frequency hip US assessment had an adverse effect on treatment outcomes compared to traditional comprehensive US monitoring. Methods. This study was a single-centre noninferiority randomized controlled trial. Infants aged under six months whose hips were reduced and centred in the harness at initiation of treatment (stable dysplastic or subluxable), or initially decentred (subluxated or dislocated) but reduced and centred within four weeks of PH treatment, were randomized to our current standard US monitoring protocol (every clinic visit) or to a limited-frequency US protocol (US only at end of treatment). Groups were compared based on α angle and

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 (α. SP. ),

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. A systematic search of PubMed, Embase, The Cochrane Library, OrthoSearch, and Web of Science from the date of inception of each database until 27 March 2022 was performed. The primary outcome of interest was the prevalence of late detection of DDH, diagnosed after three months. Secondary outcomes of interest were the prevalence of abduction bracing treatment and surgical procedures performed in childhood for dysplasia. Only studies describing the primary outcome of interest were included.Aims
