A neonatal fracture-separation of the distal humeral chondroepiphysis occurred associated with a difficult footling breach delivery. The diagnosis can be predicted when a physical examination of an apparently "dislocated" elbow reveals a normal triangular relationship between the olecranon process and the medial and lateral epicondyles. The injured epiphysis tethered on a wide-based periostium. Acceptable reduction was obtained by alignment of the fracture fragments and avoidance of an abnormal varus or valgus alignment. Healing was rapid, and remodeling as well as range of motion were excellent at six months.
一名新生儿肱骨远端软骨骨骺骨折分离，与臀位足先露难产有关。当对看似“脱位”的肘部进行体格检查时，若发现鹰嘴突与内、外上髁之间的三角关系正常，即可做出诊断。受伤的骨骺附着在宽阔的骨膜上。通过使骨折碎片对线并避免内翻或外翻畸形对线，实现了可接受的复位。愈合迅速，六个月时的重塑和活动范围均良好。
