Despite the presence of screening programmes, infants continue
to present with late developmental dysplasia of the hip (DDH), the
impact of which is significant. The aim of this study was to assess
infants with late presenting dislocation of the hip despite universal
clinical neonatal and selective ultrasound screening. Between 01 January 1997 to 31 December 2011, a prospective, longitudinal
study was undertaken of a cohort of 64 670 live births. Late presenting
dislocation was defined as presentation after three months of age.
Diagnosis was confirmed by ultrasound and plain radiography. Patient
demographics, referral type, reason for referral, risk factors (breech
presentation/strong family history) and clinical and radiological
findings were recorded.Aims
Patients and Methods
Abduction bracing is commonly used to treat developmental dysplasia of the hip (DDH) following closed reduction and spica casting, with little evidence to support or refute this practice. The purpose of this study was to determine the efficacy of abduction bracing after closed reduction in improving acetabular index (AI) and reducing secondary surgery for residual hip dysplasia. We performed a retrospective review of patients treated with closed reduction for DDH at a single tertiary referral centre. Demographic data were obtained including severity of dislocation based on the International Hip Dysplasia Institute (IHDI) classification, age at reduction, and casting duration. Patients were prescribed no abduction bracing, part-time, or full-time wear post-reduction and casting. AI measurements were obtained immediately upon cast removal and from two- and four-year follow-up radiographs.Aims
Methods
Open reduction is required following failed conservative treatment
of developmental dysplasia of the hip (DDH). The Ludloff medial
approach is commonly used, but poor results have been reported,
with rates of the development of avascular necrosis (AVN) varying
between 8% and 54%. This retrospective cohort study evaluates the
long-term radiographic and clinical outcome of dislocated hips treated
using this approach. Children with a dislocated hip, younger than one year of age
at the time of surgery, who were treated using a medial approach
were eligible for the study. Radiographs were evaluated for the
degree of dislocation and the presence of an ossific nucleus preoperatively,
and for the degree of AVN and residual dysplasia at one and five
years and at a mean of 12.7 years (4.6 to 20.8) postoperatively.
Radiographic outcome was assessed using the Severin classification,
after five years of age. Further surgical procedures were recorded.
Functional outcome was assessed using the Pediatric Outcomes Data
Collection Instrument (PODCI) or the Hip Disability and Osteoarthritis
Outcome Score (HOOS), depending on the patient’s age.Aims
