Three cases of subluxation of the hip joint occurred during femoral lengthening using the Wagner technique. This infrequent complication, which may result from a conflict of force vectors at the hip joint during lengthening, can, when left untreated, nullify the benefits of such a procedure. We suggest that increased awareness and closer monitoring can improve the prognosis for patients undergoing this course of therapy, especially where a previous hip operation has been performed.
