锁定加压钢板内固定治疗胫骨骨折的疗效

目的探讨锁定加压钢板（locking compression plate,LCP）内固定治疗胫骨骨折的疗效。方法24例胫骨骨折患者采用LCP内固定治疗。在影像增强器监视下先行闭合复位或小切口切开复位,复位满意后采用经皮微创接骨术于肌肉下骨膜外置入LCP,再次确认位置满意后通过导向器经皮拧入锁定螺钉。结果随访7~24个月,平均8.6个月。全部患者切口均I期愈合;有1例钢板断裂,无术后切口感染、骨折再移位、骨折不愈合等并发症发生。骨折愈合时间10-16周,平均12.7周。术后膝关节功能（HSS）评分70-92分,平均86.5分;优22例,良2例。踝关节功能（AOFAS）评分86-93分,平均89.9分;优19例,良5例。所有患者患肢功能均恢复良好。结论LCP内固定治疗胫骨骨折软组织创伤小、对骨骼血供影响小、骨折愈合及功能恢复快。

Treatment Efficacy in Tibial Fractures Interfixation with Locking Compression Plate

Objective To elucidate the efficacy of locking compression plate（LCP） interfixation in treatment of tibial fractures.Methods Twenty-four cases of tibial fractures were treated with LCP.Close reduction or open reduction with smaller incision was performed under the image intensifier.LCP was put under muscel and out of periosteum by the minimally invasive percut-aneous osteosynthesis technique after successful reduction.The clinical and radiological assessment was excellent,and locking nail was screwed through skin.Results All patients had been follow-up for 7 to 24 months with an average of 8.6 months.All wounds were healed at primary stage.Only one steel plate was broke.No infection,no displacement,and no cases of non-union took place.Fracture healing time was 10 to 16 weeks with an average of 12.7 weeks.The mean hospital for special surgery shoulder-rating score sheet（HSS）score for knee joint was 70 to 92 with average 86.5 and excellent in 2,good in 2.America orthopedic foot ankle society（AOFAS）score for ankle joint was 86 to 93 with average 89.9 and excellent in 19,good in 5.Function of all the extremities restored well.Conclusion Obvious advantages using LCP interfixation in treatment of tibial fractures：Less soft tissue trauma,less effect to the blood vessel of the bone,fracture heal,and satisfactory function recovery.
