43 patients (Watson-Jones Type I 12, II 4, III 0, IV 6, nondisplacement 3, partial fracture 7) who were treated from 1969 through 1981 at Kyushu Rosai Hospital were analysed. 4 patients had ulner nerve palsy, 1 radius head fracture, 7 avulsion fracture of lateral condyle, 5 fracture in medial joint space.Ten patients were followed. The length of follow up averaged 6 years (range from two to ten years). Almost all patients had solid change or habitual luxation or Tinel-like sign of ulner nerve. Seven of the ten have slight limit of extension. Eight patients have slight elbow instability. A few cases have arthrosis change, sharpness of olecranon tip and narrowness of joint space, because of the damage of joint cartilage and the elbow instability. Ruptured medial collateral ligament should be reconstructed.
