肱骨髁上截骨交叉克氏针联合可吸收张力带固定治疗儿童肘内翻

目的探讨肱骨髁上截骨交叉克氏针联合临时张力带手术治疗儿童肘内翻畸形的临床效果。方法对26例肘内翻畸形患儿均行肱骨髁上闭合楔形截骨术、交叉克氏针联合临时张力带内固定治疗。观察治疗前后提携角的变化、肘关节活动度、肘关节功能和并发症的发生情况。结果26例均获12—36个月的随访。截骨处于术后8周骨性愈合：术后3个月肘关节功能恢复至正常或达到术前范围。无一例术后提携角丢失，无肘内翻畸形复发、感染、退针及桡、尺神经损伤。结论采用交叉克氏针联合可吸收张力带作肘内翻截骨后内固定，具有操作简单、固定牢靠，内固定取出方便、创伤小及并发症少等优点，是治疗儿童肘内翻畸形较好的方法。

Supracondylar Osteotomy and Crossed Kirschner Wire Tension Band Fixation for Cubitus Varus in Children

Objective To explore the effects of supracondylar osteotomy and crossed Kirschner wire tension band fixation on cubitus varus in children. Methods Twenty-six children with cubitus varus were treated with lateral closing wedge supracondylar osteotomy and crossed Kirschner wire tension band fixation.Changes in carrying angle,range of elbow movement,elbow joint function and compli- cations were observed before and after treatment. Results All the 26 children were followed up for 12- 36 months. Bone union was achieved 8 weeks after＇ operation. Elbow joint function recovered to normal or preoperative range 3 months after operation. No children had carrying angle loss,cubitus varus recurrence,infection, needle withdrawing, and radial and ulnar nerve injuries.Conclusion Cross Kirsc- hner wire tension band internal fixation in supracondylar osteotomy is effective for cubitus varus with the advantages of minimal invasion,simple manipulation,reliable fixation, few complications,and convenient removal of internal fixation devices.
