A 50-year experience with bone graft epiphysiodesis in the treatment of slipped capital femoral epiphysis.

A "millennium" update of all cases of slipped capital femoral epiphysis treated by bone graft epiphysiodesis between 1950 and 2000 was conducted. All cases were followed for at least 1 year to evaluate the occurrence of re-slippage, avascular necrosis (AVN), chondrolysis, or complications secondary to the surgical approach. This study adds 109 patients and 133 hips to the initial report for a total of 268 patients and 318 hips. The patients include 43 patients with 45 acute slips and 225 patients with 273 chronic slips. The results include three cases of AVN, six cases of re-slippage, one case of chondrolysis, and no surgical approach complications in the acute group. In the chronic group, there were 4 cases of AVN, 17 cases of re-slippage, 4 cases of deep wound infection, and no cases of chondrolysis. The authors suggest that bone graft epiphysiodesis is a reasonable alternative in the treatment of slipped capital femoral epiphysis.
