The early detection and management of unstable concentric closed reduction of DDH with percutaneous K-wire fixation in infants 6 to 12 months of age.

Background: In some infants with developmental dysplasia of the hip, concentric closed reduction, although initially achievable, cannot be maintained even by casting because of a deficient posterior acetabular wall. Usually, these hips will redislocate in the cast and a rereduction will be necessary, often requiring an open reduction subsequently.

Methods: A 3-year retrospective review of 88 infants, (M/F; 14/74) 6 to 12 months of age with 124 dislocated hips, was conducted to assess the efficacy of percutaneous Kirschner wire fixation in achieving permanent hip stability.

Acetabular cartilaginous angle: a new method for predicting acetabular development in developmental dysplasia of the hip in children between 2 and 18 months of age.

Background: A new method of arthrographic measurement, the acetabular cartilaginous angle (ACA), is described here in an effort to find a simple, reliable, and reproducible measurement that can predict future acetabular development after successful closed reduction of developmental dysplasia of the hip (DDH).

Methods: A prospective study was conducted for children with DDH who were treated successfully by closed reduction in the authors' institute from 1994 through 2000. The total number of patients who completed the follow-up in our study until full acetabular development or acetabuloplasty was 162, with 234 affected hips.

The role of arthrography-guided closed reduction in minimizing the incidence of avascular necrosis in developmental dysplasia of the hip.

Avascular necrosis of the femoral head is the most serious complication after closed reduction in developmental dysplasia of the hip. Although arthrography has a well-established role in the treatment of developmental dysplasia of the hip, its use is not universal. A prospective study was conducted to compare the incidence of avascular necrosis after closed reduction in developmental dysplasia of the hip performed with and without arthrography in 85 patients, with a minimum of 5 years follow up.

The pattern of developmental dysplasia of the hip.

Objective: This study was conducted to enlarge the knowledge of developmental dysplasia of the hip (DDH) in the Kingdom of Saudi Arabia (KSA), and to compare its presentation among Saudi population to known international figures.

Methods: A prospective study of Saudi patients with DDH that presented to King Khalid University Hospital, Riyadh, KSA over 5 years starting September 1996. The information needed was obtained directly from one or both parents.

Fixed forefoot adduction after clubfoot surgery.

Objective: Studying the causes of residual forefoot adduction deformity after surgical treatment of congenital clubfoot and their management.

Methods: Revision surgery was carried out by the author for 12 patients (13 feet) in King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, during the period between January 1997 to December 1998.

Results: In 12 out of 13 feet, K-wire was not used to fix the navicular bone in its reduced position during primary surgery.
