闭合复位经皮克氏针内固定治疗小儿肱骨髁上不稳定型骨折

目的 :小儿肱骨髁上不稳定型骨折并发症多 ,治疗不当经常会产生严重后遗症。该文旨在观察闭合复位后经皮克氏针交叉固定治疗此类骨折的临床疗效。方法 :回顾性临床研究 14例小儿肱骨髁上不稳定型骨折病人经全麻下行闭合复位 ,经皮克氏针交叉内固定治疗效果及并发症的分析。结果 :平均随访 10个月 (6～ 12个月 ) ,所有骨折术后 4周骨痂愈合良好 ,拔除克氏针。术后 8周肘关节功能恢复。 2例暂时性神经麻痹病人术后 12周和 16周神经功能完全恢复。 2例早期肌间膈综合征病人复位固定后症状消失 ,无肘关节畸形和永久性神经血管损伤发生。结论 :闭合复位经皮克氏针交叉内固定是治疗小儿肱骨髁上移位不稳定型骨折的理想的选择方法。

CLOSED REDUCTION AND PERCUTANEOUS K-WIRE FIXATION OF UNS TABLE SUPRACONDYLAR HUMERUS FRACTURES IN CHILDREN

Objective: To observe the effects of closed reduction and percutaneous k-wires fixation of unstable supracondylar humerus fractures in children. Methods: Retrospective review of fourteen patients who sustained displaced unstable supracondylar fractures of distal humerus treated by closed reduction and percutaneous k-wires fixation. Results: All patient's k-wires were removed at OPD 4 weeks post-operation. Their elbow function regained at 8 weeks. After averaged 10 month (varies from 6 to 18 month) followed-up, all fractures healed very well without any permanent complications. Two transients nerve palsy, one ulnar never, and one radial nerve, recovered completely at 12 weeks and 16 weeks post-operation respectively. Conclusions: Closed reduction and percutaneous k-wires fixation of unstable supracondylar fractures of distal humerus is a safe and effective method in the treatment of displaced unstable supracondylar humerus fractures in children.
