A previously undescribed anomaly of the distal femur occurred in a 3-month-old child with arthrogryposis multiplex congenita. There was a large boss of bone superior and posterior to the true lateral femoral condyle with which the lateral tibial femoral condyle articulated. To obtain full extension of the knee, it was necessary to perform a full posterior release and to replace the tibial condyle distally onto the true lateral condyle. The etiology of the anomaly remains conjectural, but the lesion should be sought for in patients with resistant flexion contracture requiring surgical release.
一名患有先天性多发性关节挛缩症的3个月大儿童出现了一种此前未被描述过的股骨远端异常情况。在真正的外侧股骨髁的上方和后方有一个大的骨突，外侧胫股关节与之相连。为了使膝关节完全伸直，有必要进行完全的后侧松解，并将胫骨髁向远端重新放置在真正的外侧髁上。这种异常情况的病因仍属推测，但对于需要手术松解的顽固性屈曲挛缩患者，应检查是否存在这种病变。
