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. Arthrographic criteria were evaluated including lateralization of the femoral head and the type of limbus encountered. Hips treated by closed reduction based on arthrographic evaluation had significantly less incidence of avascular necrosis when compared with those treated by closed reduction without arthrographic guidance. Closed reduction with lateralization of more than 4 mm, and those hips with an inverted limbus were associated with an increased risk of avascular necrosis.

Böhler's and Gissane's angles of the calcaneus in the Saudi population.

OBJECTIVE: The purpose of this study is to measure Böhler s angle (BA) and Gissane s angle (GA) in the Saudi population and compare their values to the published data. METHODS: Lateral plain radiographs of 229 normal feet and ankles of 158 females and 71 males, with age range of 15-72 years, were studied retrospectively at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between 2002 and 2003. Böhler's angle and GA were measured and the mean and standard deviation of each angle were calculated. The relationship between each angle and age, gender, and side of body was tested, and compared to international figures. RESULTS: The mean BA in the Saudi population was 31.21 degree with a range of 16-47 degree. The mean GA was 116.16 degree with a range of 96-152 degrees. Böhler's angle and GA are not significantly related to age, gender, or side of body. Moreover, the range of both angles was wider than that reported in the literature. CONCLUSION: The study shows the difference between the Saudi and various other populations in regard to BA and GA, and reinforces the need to establish the normal ranges of BA and GA in a given population.

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. RESULTS: Six hundred Saudi children were included in this study. The diagnosis of DDH was delayed in most patients. The results give an impression that parents' consanguinity, positive family history, breech deliveries and the use of swaddling have direct relation with increased incidence of DDH in the Saudi population. CONCLUSION: A national screening program is needed in KSA. Furthermore, nationwide studies will help to identify groups at risk and the geographical distribution of the disorder.

Physeal bridge resection.

Growth arrest secondary to physeal bridge formation is an uncommon but well-recognized complication of physeal fractures and other injuries. Regardless of the underlying etiology, physeal bridges may cause angular and/or longitudinal growth disturbances, with progression dependent on the remaining physeal growth potential. Physeal bridge resection and insertion of interposition material releases the tethering effect of the bridge. Physeal bridge resection has become an accepted treatment option for patients with existing or developing deformity and for those with at least 2 years or 2 cm of growth remaining. Current experimental research is focused on the use of gene therapy and other factors that enhance chondrocyte proliferation to improve the management of growth arrest. The use of cartilage and cultured chondrocytes as interposition material after physeal bridge resection is an area of active research.
