微型锁定解剖钢板治疗难复性儿童肱骨近端干骺端骨折

The mini-locking anatomical plate for treatment of the refractory proximal humeral metaphysic fracture in children

目的探讨微型锁定解剖钢板治疗难复性儿童肱骨近端干骺端骨折的疗效。方法应用微型锁定解剖钢板治疗20例难复性儿童肱骨近端干骺端骨折患儿。记录手术时间、并发症及患儿骨折恢复情况。术后6个月采用肩关节Constant-Murley评分标准评价疗效。结果患儿均获得随访,时间6~26(16.6±4.5)个月。手术时间39~61(45.6±5.3)分。切口均一期愈合,无深部感染、血管及神经损伤等并发症发生,无内固定松动、失效及断裂等情况发生。骨折均骨性愈合,时间5~12(9.8±1.3)周。术后6个月肩关节Constant-Murley评分优良率19/20。结论微型锁定解剖钢板治疗难复性儿童肱骨近端干骺端骨折固定可靠、操作简单,患儿术后恢复快,总体疗效满意。

Objective To investigate the effect of mini-locking anatomical plate for treatment of the refractory proximal humeral fracture in children. Methods Twenty children with the refractory proximal humeral fractures were treated with the mini-locking anatomical plate. The following data were collected,including the surgery time,the occurrence of complications and the fracture recovery situation. At 6 months postoperaiton,Constant-Murley score criterion was used for the efficacy evaluation. Results All cases were followed up for 6 ~ 26( 16. 6 ± 4. 5) months,and the operation time was 39 ~ 61( 45. 6 ± 5. 3) points. The surgical incision got primary healing,without the complications such as deep infection,blood vessels or nerve injury. There were not internal fixation loosening,failure or breakage. All fractures got bony healing within 5 ~ 12( 9. 8 ± 1. 3) weeks. The excellent-good rate of Constant-Murley score was 19/20 at 6 months postoperation. Conclusions The use of mini-locking anatomical plate is a reliable,simple,and satisfying therapeutic strategy for treatment of the refractory proximal humeral metaphysic fracture.
