改良可吸收张力带内固定治疗儿童肘关节关节内骨折125例

Treatment of pediatric elbow intra-articular fractures by absorbable rod plus absorbable tensile band:a report of 125 cases

目的探讨可吸收棒可吸收线张力带固定治疗儿童肘关节关节内骨折的疗效及安全性。方法2012年6月至2014年12月作者共收治125例肘关节关节内骨折患者，其中肱骨外髁骨折96例，肱骨内髁骨折6例，尺骨鹰嘴骨折20例，桡骨小头合并尺骨鹰嘴骨折3例；均采用可吸收棒联合OS线张力带固定，术后定期随访，进行临床与影像学评估。结果125例患者中，121例获得随访，随访时间6～24个月，平均（14．5±8．5）个月；骨折愈合时间为6—8周，平均（8．5±2．5）周，临床疗效优良率为96．6％。未发生伤口感染、尺神经损伤、可吸收棒退出、关节僵硬、骨化性肌炎等并发症。结论可吸收棒加可吸收线张力带内固定治疗儿童肘关节关节内骨折稳定好，利于骨折愈合，可避免再次手术，值得临床上推广应用。

Objective To explore the clinical efficacy and safety of absorbable rod plus absorbable ten- sile band for pediatric elbow intra-articular fractures. Methods A total of 125 patients with elbow joint frac- tures underwent OS suturing with absorbable rod. Regular postoperative follow-ups were performed to access the clinical and radiographic outcomes. Results Among them, 121 patients were followed up. The fracture types were of lateral humeral condyle （ n = 96 ）, medial humeral epicondyle （ n = 6 ）, ulna olecranon （ n = 20 ） and combined radial capitulum ＆ ulna olecranon（ n = 3 ）. The average follow-up period was （ 14. 5 ± 8.5 ） （ 6 - 24） months. The average duration of fracture healing was （ 8.5 ±2. 5 ） （ 6 - 8 ） weeks. And the clinical excel- lent rate was 96. 6%. There were no such complications as wound infection, ulnar nerve injury, rod withdraw- al, stiff joint or myositis ossificans. Conclusions The method of absorbable rod plus absorbable tensile band may be employed for treating pediatric elbow intra-articular fractures. With excellent stability and healing, it may avoid a second operation and is worthy of wider clinical popularization.
