动力加压钢板或锁定加压钢板治疗肱骨干骨折

目的:比较动力加压钢板(dynamic compression plate,DCP)和锁定加压钢板(1ocking compres-sion plate,LCP)治疗肱骨干骨折的效果。方法:对2007年6月～2010年6月于外侧入路下行DCP、LCP分别治疗18例、11例肱骨干骨折的临床资料进行回顾性分析。结果:术后均随访5～20个月,平均10.5个月。DCP组骨折于14～30周愈合,平均16.7周,包括1例固定失败行翻修手术者。LCP组骨折于13～19周愈合,平均13.8周。LCP组较DCP组骨折平均愈合时间明显缩短,两组比较差异有统计学意义(P<0.05)。肩关节功能按Neer评分,DCP组优13例,良5例。LCP组优8例,良3例;肘关节功能按Mayo评分,DCP组优14例,良4例。LCP组优9例,良2例。两组比较差异无统计学意义(P>0.05)。3例术前桡神经损伤者于术后14～28周基本恢复,平均18.3周。两组均无术中神经损伤。结论:切开复位结合LCP内固定是治疗肱骨干骨折安全有效的方法。

Treating humeral shaft fractures by dynamic compression plate or locking compression plate

Objective： To compare the effects of dynamic compression plate（DCP） and locking compression plate（LCP） on humeral shaft fracture.Methods： Data of 29 patients with humeral shaft fracture were treated with the DCP（18 cases） or LCP（11 cases） from Jun 2007 to Jun 2010 were retrospectively analyzed.Results： An average of 10.5 months follow up ranging from 5 to 20 months was conducted in these patients.The union of fractures was achieved in an average of 16.7 weeks（ranging from 14-30 weeks） for those underwent DCP which was significant shorter than the corresponding 13.6 weeks（ranging from 13-19 weeks） for patients had LCP（P〈0.05）.According to the Neer Scoring System for the shoulder function evaluation,13 patients had an excellent result,5 had a good result in DCP group,the corresponding number was 8 and 3 in LCP group.The damaged function of the radial nerves in 3 cases mostly recovered in an average of 18.3 weeks ranging from 14-28 weeks.Conclusion： Open-reduction skill combing with LCP fixation are effective and safe treatment the humeral shaft fracture.
