Growth of the acetabular lateral cartilage in relation to congenital and developmental dysplasia of the hip. An histological study.

There are no clear explanations for the spectrum of hip dysplasia nor for the observation that in normal and dysplastic hips, final development may be unpredictable with or without treatment. Immunohistochemical and histological studies of a three month old child's acetabulae were performed. Multiple inclusions were found in the lateral ring epiphysis and in the three flanges of the triradiate cartilage.

The outcome of patients with hinge abduction in severe Perthes disease treated by shelf acetabuloplasty.

Background: The management of patients with Perthes disease remains controversial. In children with hinge abduction and the potential for remodeling, we have performed a shelf acetabuloplasty, in an effort to contain the hip and allow remodeling. We report our medium-term results in a consecutive series of 27 children with severe Perthes disease and arthrographically proven hinge abduction.

Hip arthrography in the assessment of children with developmental dysplasia of the hip and Perthes' disease.

In our unit, children with developmental dysplasia of the hip or Perthes' disease, for whom an operation is considered, undergo examination under anaesthetic and a hip arthrogram. This prospective study assessed whether the arthrogram modified treatment and analysed the reliability of its interpretation. All children undergoing a hip arthrogram for developmental dysplasia of the hip and Perthes' disease over a 12-month period were included.

Perthes' disease associated with osteogenesis imperfecta.

Primary hip disorders, such as congenital hip dislocation, have rarely been reported in children with osteogenesis impefecta (OI). Protrusio acetabuli and coxa vara secondary to severe osteopenia and recurrent fractures are common. Perthes' disease in association with osteogenesis imperfecta has not been reported previously.

Humeroradial synostosis and the multiple synostosis syndrome: case report.

Humeroradial synostosis may occur sporadically or as an extremely rare inheritable disorder. The current classification divides cases into class I (fixed in extension with ulnar ray hypoplasia) or class II (fixed in flexion without hypoplasia). Familial cases of class II synostosis segregate into autosomal recessive and autosomal dominant groups.

An aetiological classification for developmental synostoses at the elbow.

Synostoses at the elbow joint are rare. The literature divides them into three groups based on the nature of bony ankylosis; the commonest are humeroradial synostoses. Approximately 150 cases have been reported.

The classification of congenital talipes equinovarus.

e have assessed the reliability of four classification systems for club foot. Four observers evaluated nine children (18 feet) at different stages in the first six months of life, a total of 180 examinations. Each observer independently assessed all feet according to the classification systems described by Catterall, Diméglio et al, Harrold and Walker, and Ponseti and Smoley.

Ultrasound screening of the infant's hip: introduction of a new combined angle.

This study evaluates the most widely used sonographic measurements for judging an infant's hip morphology. The alpha and beta angles of Graf, the bony coverage percentage of Morin and a new combined angle were analysed. This latter angle records the direction of the whole acetabulum (cartilagenous and bony) as one unit.
