[Slipped epiphysis of the head of femur, 373 cases between 1948 and 1973 (author's transl)].

Indications and results of 324 grafted or nailed slipped epiphyses, 45 Imhäuser operations and 7 Wiberg osteotomies are analyzed. Fixation in situ gave relatively good long-term results in spite of major displacement. Indication for correction should be based less on pre-arthrotic deformity than on clinical considerations. Deformity does not always correspond to development of arthrosis, but is determined in parts by dystrophy of cartilage. Results of Imhäuser's osteotomy are assessed mainly in terms of joint-function, their indications follow his guidelines. Prophylactic nailing and open reduction are discussed.
