Á Heeg M. Visser JD. Oostvogel HJ. Journal of Bone & Joint Surgery - British Volume. 70(1):34-7, 1988 Jan. Four patients with injuries of the acetabular triradiate cartilage are * presented. In three of them premature fusion of the cartilage occurred; two of these developed acetabular deformity and subluxation of the hip. In all patients the sacroiliac joint also was injured; in two, the joint was completely disrupted, leading to fusion and growth disturbance of the Á ilium. As injury of the triradiate cartilage is easily missed on the initial radiograph, it is advised that all patients with pelvic trauma should be followed clinically and radiographically for at least one year. *
