title: Physeal remodeling after internal fixation of slipped capital femoral epiphyses.
abstract: Rounding off the femoral neck metaphysis helps improve hip function in slipped capital femoral epiphysis (SCFE). Remodeling by physeal growth, not previously reported, may also contribute. By studing the changes in physeal-shaft angle after internal fixation (IF), we found evidence of physeal remodeling in one of 21 mild, five of 23 moderate, and in all of 11 severe slips. Although the amount of remodeling averaged 11.7 degrees, it occurred in 100% of severe slips (p less than 0.001). This support the use of initial pin fixation and a wait of at least 2 years before realignment femoral neck osteotomies are considered.
