[The treatment of leg length discrepancy using Phemister's method of epiphysiodesis].

A retrospective study is reported of the results of epiphysiodesis in 67 children. In 47 patients (70%) the final inequality was less than or equal to 1.0 cm. In 9 patients the final inequality was greater than or equal to 1.6 cm. The average leg length inequality could be reduced from 3.2 cm preoperatively to 1.2 cm at maturity. Technical errors were minimal. Failures (9 patients) resulted mainly from problems in timing epiphysiodesis.
