BACKGROUND Acetabular dysplasia (AD) is the main cause of hip osteoarthritis in Japan. A simple method to evaluate acetabular dysplasia would be helpful for early treatment or prevention of hip osteoarthritis. Acetabular dysplasia is reported to be associated with pathological transverse growth of the pelvis, indicating that the distance between the 2 anterior superior iliac spines might be use...

Shelf arthroplasty is briefly reviewed in historical perspective and the results in 45 hips (39 patients) which had undergone this procedure at the Royal Children's Hospital are presented. The majority of these patients were adolescents who had previously been treated for congenital dislocation or subluxation of the hip. The indications for operation and the operative technique are discussed. C...

BACKGROUND The age when patients present for treatment of symptomatic developmental dysplasia of the hip with periacetabular osteotomy (PAO) varies widely. Modifiable factors influencing age at surgery include preexisting activity level and body mass index (BMI). The severity of the hip dysplasia has also been implicated as a factor influencing the age at arthritis onset. The purpose of this st...

Introduction: Congenital Zika syndrome can generate microcephaly and spastic motor syndromes, limb deformities, arthrogryposis. Hip dysplasia, associated with this syndrome, is frequent but poorly studied. Objective: To describe the radiographic alterations of hip in patients Syndrome (CZS). Methods: Observational cross-sectional cohort study. We studied 25 a serological diagnosis CZS sample 50...

Shelf operations performed on 24 patients (27 hips) for late presentation of congenital hip dysplasia were evaluated. The mean age at operation was 14 years 9 months and the mean follow-up 16 years 8 months. Two-thirds of the hips had good clinical results at follow-up. Patients operated on under the age of 20 years and with little or no radiological evidence of degenerative joint changes had t...

49,XXXXY is rare chromosomal pattern and these patients have mental retardation, small penis, cryptorchidism and skeletal anomalies. We reported a 10 month-old boy who has hypotonia, microcephaly, hypertelorism, depressed nasal bridge, epicanthic folds and bilateral multiple ear tags, high arched palate, down set ears, micrognathia and congenital heart disease such as patent ductus arteriosus (...

A wide variety of neuromuscular diseases affect children, including central nervous system disorders such as cerebral palsy and spinal cord injury; motor neuron disorders such as spinal muscular atrophy; peripheral nerve disorders such as Charcot-Marie-Tooth disease; neuromuscular junction disorders such as congenital myasthenia gravis; and muscle fiber disorders such as Duchenne's muscular dys...

OBJECTIVE To estimate the prevalence of hip osteoarthritis (OA hip) and hip dysplasia in a sample of Hong Kong men who were unselected with respect to hip symptoms. METHODS The postmicturition films of 999 men aged 60-75 years, consecutive attenders for intravenous urography between 1987 and 1990 at a regional hospital, were reviewed. OA hip was diagnosed as the occurrence of two or more feat...

The aim of this study is to systematically review the literature with regards to surgical treatment of patients with hip joint osteochondromas, and to report our surgical management of three paediatric patients who had femoral neck or acetabular osteochondromas in association with acetabular dysplasia. We performed a systematic review using PubMed and Embase databases for all studies that repor...
