New plate for lateral translation in valgus intertrochanteric osteotomy (CUN plate).

A new plate is presented for internal fixation of valgus intertrochanteric osteotomy. This plate enables a controlled translation, permits dynamic compression of the osteotomy line and eludes some of the complications involved in the use of other double-angle plates. The morphological characteristics of the plate as well as its technical and surgical aspects are described. A follow-up study of 63 patients operated on between January 1978 and June 1980 has been carried out, underlining some of the mistakes that can affect the healing time.
