No consensus exists concerning the best pin configuration for displaced supracondylar fractures of the humerus in children. Although cross-pinning is the most stable biomechanically, this configuration may cause iatrogenic ulnar nerve palsy. For the last 7 years, we have been using a three-pin fixation technique with insertion of two K wires from the lateral side (elbow in full flexion) and the third wire through the medial side (elbow in full extension). We used this technique in 67 displaced supracondylar fractures without any complications related to the ulnar nerve. The technique provides excellent stability and eliminates the risk of iatrogenic ulnar nerve palsy.
关于儿童肱骨髁上移位骨折的最佳克氏针配置尚无共识。尽管交叉克氏针固定在生物力学上最稳定，但这种配置可能导致医源性尺神经麻痹。在过去7年中，我们一直采用一种三针固定技术，即从外侧（肘关节完全屈曲）插入两根克氏针，第三根针从内侧（肘关节完全伸直）穿过。我们将该技术应用于67例肱骨髁上移位骨折，未出现任何与尺神经相关的并发症。该技术提供了出色的稳定性，并消除了医源性尺神经麻痹的风险。
