Description

The role of overhead traction in the treatment of developmental dislocation of the hip, using two-directional arthrographybefore and after overhead traction, in 56 hips (47 patients) was investigated.There were 5 males (6 hips) and 42 females (50hips). Of the 56 hips, 41 were treated before walking age and 15 after walking age.The age at the time of overhead tractionranged from 5 to 22 months (average 9 months). Mau's original traction method was used in 38 hips from 1974 to 1988 andIshida's modified method in 18 hips from 1989 to 2000, but the results were poorer with the former method. Reduction ofthe femoral head was considered to be obtained when it moved to the entrance of the acetabulum after overhead traction (19of 41 hips). The shapes of the anterior and posterior portions of the limbus were corrected in 8 of 52 hips, especially in thecases treated before walking age. The superior portion of the limbus was unchanged.According to the appearance onimages, modified overhead traction appeared to be effective in achieving reduction, but could not completely correct the limbus shape.
