Preliminary traction as a single determinant of avascular necrosis in developmental dislocation of the hip.
The role of preliminary traction before closed reduction in the treatment of developmental dysplasia of the hip has been questioned by many authors lately. However, the studies advocating or opposing the use of this treatment modality include several other parameters besides traction. Thus, it is unclear whether the affection is the result of preliminary traction or concurrent variables such as the "human position." This study aimed to put forward the effect of preliminary traction as a single determinant of avascular necrosis. We had two groups of patients who had developmental dislocation of the hip. The first group consisted of 52 patients treated with preliminary traction before closed reduction and the other group comprised 40 patients treated with closed reduction without preliminary traction. Both groups were similar in age, gender, side, level of dislocation, and method and duration of immobilization. Three patients from the first group developed avascular necrosis, which was not statistically significant. Preliminary traction did not affect the rate of avascular necrosis.
