目的探讨膜诱导技术治疗成人股骨转子间骨折内固定术后慢性骨感染的疗效。
方法回顾性分析2019年5月至2022年5月期间甘肃省人民医院创伤骨科二病区收治并获完整随访的15例成人股骨转子间骨折内固定术后慢性骨感染患者资料。男13例,女2例;年龄(55.8±2.6)岁。Cierny-Mader解剖分型:Ⅲ型6例,Ⅳ型9例;宿主分型:A型10例,B型5例。骨感染病程为(22.1±8.1)个月。所有患者均采用膜诱导技术分2期治疗:一期病灶清创后骨缺损长度为(4.50±0.54)cm,在缺损区置入抗生素骨水泥,临时固定骨折断端;6~8周感染控制后行二期骨缺损修复重建手术。记录患者的感染控制情况、并发症发生情况、骨性愈合时间,以及末次随访时Samantha X线骨愈合评分、站立疼痛视觉模拟评分(VAS)、髋关节功能等。
结果15例患者术后获(27.5±2.5)个月随访。2例患者一期术后出现感染复发,予再次清创后得到有效控制,随访期间再无复发。15例患者随访期间均未发生取骨区感染、重建骨变形塌陷、肢体短缩、再骨折及内固定失效等并发症。15例患者术后均获骨性愈合,愈合时间为(10.3±2.1)个月。末次随访时15例患者的Samantha X线骨愈合评分为6.0(5.0,6.0)分,站立疼痛VAS评分为1.0(1.0,3.0)分。末次随访时根据Sanders髋关节创伤后评分标准评定髋关节功能:优10例,良5例;根据Paley感染性骨缺损愈合评分标准评定疗效:优7例,良2例,可6例。
结论膜诱导技术治疗成人股骨转子间骨折内固定术后慢性骨感染,可有效控制感染,改善患者髋关节功能,疗效良好。
ObjectiveTo explore the clinical efficacy of membrane induction technique in the treatment of chronic bone infection after internal fixation of intertrochanteric fracture in adults.
MethodsThe data were retrospectively analyzed of the 15 adult patients who had been treated for chronic bone infection after internal fixation of intertrochanteric fracture at Department of Traumatic Orthopaedics Ⅱ, Gansu Provincial People's Hospital from May 2019 to May 2022. There were 13 males and 2 females with an age of (55.8±2.6) years. By the Cierny-Mader anatomical classification, 6 cases were type Ⅲ and 9 cases type Ⅳ; by the physiological classification, 10 cases were type A and 5 cases type B. Course of bone infection was (22.1±8.1) months. All patients were treated by membrane induction technique in 2 stages. In the first stage, antibiotic bone cement was implanted after debridement into the defects [(4.50±0.54) cm in length] followed by temporary fixation of broken ends of the fracture. After 6 to 8 weeks when infection was controlled, the second stage repair and reconstruction of bone defects was carried out. Infection control, complications, bone healing time, and Samantha X-ray bone healing score, visual analogue scale (VAS) at standing, Sanders hip score and Paley score for bone defect healing at the last follow-up were recorded.
ResultsThe 15 patients were followed up for (27.5±2.5) months. Infection recurred after the first-stage operation in 2 cases, but was effectively controlled after debridement and follow-up observed no recurrence. Follow-up showed no such complications as donor site infection, deformation or collapse of the bone reconstructed, limb shortening, re-fracture or internal fixation failure in the 15 patients who achieved bony union after (10.3±2.1) months. At the last follow-up, the Samantha X-ray score was 6.0(5.0, 6.0) points and VAS at standing 1.0(1.0, 3.0) point for the 15 patients; by Sanders hip score, the hip function was rated as excellent in 10 cases and as fine in 5 cases; by Paley score for bone defect healing, the efficacy was rated as excellent in 7 cases, as good in 2 cases and as fair in 6 cases.
ConclusionIn the treatment of chronic bone infection after internal fixation of intertrochanteric fracture in adults, membrane induction technique can effectively control infection and improve the hip function of the affected limb, leading to good clinical efficacy.
