Premature closure of the physis of the greater trochanter has been reported to be a predictive sign of chondrolysis in hips with slipped capital femoral epiphysis (SCFE). In the present series, the physis of the greater trochanter showed decreased activity on bone scintigraphy in 16 patients with SCFE and concurrent or developing chondrolysis. In five of these patients, the scintigraphic pattern (decreased activity of the physis of the greater trochanter) preceded radiographic changes of chondrolysis. In 13 patients with SCFE without chondrolysis, the physis of the greater trochanter appeared normal on scintigrams and open on radiographs. Use of scintigraphy in patients with SCFE permitted earlier recognition of chondrolysis, increasing the potential of altering the course of the disease.
