微创内固定系统治疗胫骨远端粉碎性骨折

目的:观察手法闭合复位结合MIPPO技术治疗胫骨中上段、中下段骨折的临床效果.方法:2007年3月至2010年12月,治疗并获得随访的56例胫骨骨折,其中男39例,女17例；年龄22～67岁,平均41.3岁；左侧25例,右侧31例;34例为摔伤,22例为车祸伤；从受伤到手术时间平均1.7 d；中上段15例,中下段41例；临床表现小腿疼痛肿胀,活动受限.采用手法闭合复位结合MIPPO技术治疗.术后采用Johner-Wruhs关节功能评定标准对疗效进行评定.结果:56例患者,手术操作时间平均46 min,术后X线片示骨折复位满意,所有钢板螺钉位置良好；切口均Ⅰ期愈合,无表浅或深层感染.随访时间8～23个月,平均14.2个月；1例发生骨折延迟愈合,经自体髂骨植骨后骨折愈合,其余55例患者骨折在术后15～20周愈合,无固定失败；术后4～6个月均下地行走,7个月后行走无跛行,膝、踝关节功能与伤前一致且双下肢对称.按Johner-Wruhs关节功能评定标准,结果优46例,良9例,中1例.结论:手法闭合复位结合MIPPO技术治疗胫骨骨折,结合了传统正骨手法与现代骨科的优点,既保护了软组织,将手术程序简化、创伤降到最小,又能获得坚强的内固定,保证膝、踝关节的早期功能活动,具有软组织创伤小、血运破坏少、固定可靠等优点,是治疗胫骨近、远端骨折的一种有效方法,也符合微创生物学内固定观点.

Treatment of comminuted distal tibial fractures with the less invasive stabilization system(LISS)

Objective: To evaluate the clinical effects of close reduction combined with minimally invasive percutanous plate osteosynthesis(MIPPO) for proximal and distal tibial fractures. Methods: From March 2007 to December 2010,56 patients with proximal and distal tibial fractures were treated with close reduction combined with MIPPO technique. There were 39 males and 17 females,aged from 22 to 67 years with an average of 41.3 years. Left fracture was in 25 cases and right fracture was in 31 cases; proximal tibial fracture was in 15 cases and distal tibial fractures was in 41 cases;34 cases caused by fall down and 22 cases caused by road accident. The mean time from injury to operation was 1.7 d. Clinical manifestation included pain,swelling of leg with limitation of activity. According to the standard of Johner-Wruhs,clinical effects were evaluated. Results: The mean operative time was 46 min in 56 patients. All fractures obtained satisfactory reduction and the location of plate was good. Incisions healed with one-stage and no superficial or deep infection was found. All the patients were followed up from 8 to 23 months with an average of 14.2 months. Only one fracture complcation with delayed union,and after auto grafting with ilium bone,the fracture got union. Other 55 cases obtained bone healing in 15 to 20 weeks after operation and no internal fixation failure was found. The time of walking was 4-6 months after operation,without limping at 7 months after operation. Both lower extremities were symmetrical and the function of knee and ankle got complete recovery. According to the criteria of Johner-Wruhs score,46 cases obtained excellent results,9 good and 2 fair. Conclusion: Treatment of proximal and distal tibial fractures with close reduction and MIPPO technique can not only preserve soft tissue,simplify operative procedure and decrease wound,but also can obtain rigid internal fixation and guarantee early function exercises of knee and ankle joints. The method has the advantages of less soft tissue injury,less blood loss,reliable fixation,which is effective method in treating proximal and distal tibial fractures and corresponds with the standpoint of biological fixation.
