Abstract

OBJECTIVES:

Open reduction through a medial approach for the treatment of developmental dysplasia of the hip has been advocated in children younger than 18 months of age. In this study, we evaluated the results of this technique in children above 18 months of age.

METHODS:

A retrospective evaluation of 34 hips (22 patients; 16 girls, 6 boys) was made, whose treatment was performed using open reduction through a medial approach between 1987 and 1997. Only typical dislocations were included. The ages of the patients at the time of surgery were either 18 months or above (mean age 23.7 months; range 18 to 54 months). Clinical and radiographic evaluations were made according to the modified McKay and Severin's criteria, respectively. The hips in which avascular necrosis developed were evaluated according to the Bucholz-Ogden classification. The mean follow-up was 10 years (range 5 to 14 years).

RESULTS:

Secondary interventions were required in 24 hips (70.6%). Avascular necrosis developed in nine hips (26.5%). Final clinical results, together with secondary procedures, were excellent in 18 hips (52.9%), good in 10 hips (29.4%), moderate in four hips (11.8%), and poor in two hips (5.9%). Radiographically, there were six hips in Severin class I (17.7%), 11 hips (32.4%) in class II, 10 hips (29.4%) in class III, six hips (17.7%) in class IV, and one hip (2.9%) in class V.

CONCLUSION:

These data show that, because of high rates of secondary interventions and ensuing avascular necrosis, open reduction through a medial approach cannot be considered to be successful for the treatment of developmental dysplasia of the hip in children above 18 months of age.
