摘要:
目的 探讨基于骨整形理念治疗Gustilo ⅢB型踝关节开放性骨折的临床效果。 方法 该研究为回顾性病例系列研究。2018年1月—2024年8月,无锡市第九人民医院收治33例符合入选标准的Gustilo ⅢB型踝关节开放性骨折患者,其中男25例、女8例,年龄25~65(44±12)岁,皮肤软组织缺损面积为6 cm×3 cm~27 cm×14 cm,骨缺损长度为3.0~9.2 cm(平均3.7 cm)。对所有患者均基于骨整形理念进行治疗。Ⅰ期第1阶段:急诊彻底清创后,于胫骨缺损区置入抗生素骨水泥,采用外固定支架或被覆抗生素骨水泥的钢板进行临时固定,并修复神经、肌腱,残留创面以负压封闭引流敷料覆盖;Ⅰ期第2阶段:伤后第3~7天再次清创并更换抗生素骨水泥,根据骨折情况调整或保留内固定,设计并切取股前外侧皮瓣(面积为7 cm×3 cm~30 cm×15 cm)修复创面。根据缺损大小及局部张力,对供区创面采用阶梯式处理:张力小者直接拉拢缝合;张力大者,术中先适度拉拢创缘,待术后水肿消退后,再行直接缝合或取对侧大腿刃厚皮片修复。Ⅱ期第3阶段(唯一阶段):伤后7~30周(平均15.8周)取出抗生素骨水泥,计算骨缺损体积并精确切取髂骨后与万古霉素混合填塞骨缺损,缝合诱导膜及皮肤软组织。记录术后皮瓣成活情况及不同阶段感染相关并发症发生情况。随访时记录皮瓣外观、质地,皮瓣供受区瘢痕情况,骨愈合情况。末次随访时,采用足踝功能评估量表评估患足功能并计算其日常生活能力恢复百分比,通过36项健康调查简表(SF-36)评估患者健康结局,计算患者的生理健康总评和心理健康总评得分。 结果 术后皮瓣完全成活者30例;皮瓣部分坏死者3例,其中1例经清创后直接缝合,2例经清创植皮后愈合。发生感染相关并发症者4例,其中浅表感染者3例(Ⅰ期第2阶段后1例,Ⅱ期第3阶段后2例),经清创后感染得到控制,创面愈合;骨感染者1例(Ⅰ期第2阶段后),经再次彻底清创、抗生素骨水泥填塞后感染得到控制,植骨愈合。随访12~57个月(平均26.7个月),所有皮瓣颜色、质地良好;皮瓣供区发生瘢痕增生者3例,皮瓣受区仅遗留线性瘢痕。末次随访时,患足足踝功能评估量表评分为(71±4)分,日常生活能力恢复至(85±5)%;SF-36中的生理健康总评得分为(78±4)分,心理健康总评得分为(70±11)分。 结论 基于骨整形理念治疗Gustilo ⅢB型踝关节开放性骨折,术后感染率及其他并发症发生率低,且踝关节功能恢复良好。 Abstract:Objective To investigate the clinical efficacy of applying orthoplastic principle in treating Gustilo type ⅢB open ankle joint fractures. Methods This study was a retrospective case series study. From January 2018 to August 2024, 33 patients with Gustilo type ⅢB open ankle joint fractures who met the inclusion criteria were admitted to Wuxi Ninth People's Hospital, including 25 males and 8 females, aged 25-65 (44±12) years. The area of skin and soft tissue defects ranged from 6 cm×3 cm to 27 cm×14 cm. The length of bone defect ranged from 3.0 to 9.2 cm (with mean of 3.7 cm). All patients were treated based on the orthoplastic principle. Phase Ⅰ-Stage 1: after thorough debridement was performed in emergency department, antibiotic bone cement was inserted in the tibial defect, an external fixator or an antibiotic bone cement-coated steel plate was applied for temporary stabilization. Nerves and tendons were repaired, and the remaining wound was covered with vacuum sealing drainage dressing. Phase Ⅰ-Stage 2: on days 3 to 7 after injury, the wound was debrided again, and the antibiotic bone cement was replaced. The internal fixation was adjusted or retained according to the fracture status, and an anterolateral thigh flap (with size ranging from 7 cm×3 cm to 30 cm×15 cm) was designed and harvested to repair the wound. A stepwise strategy was employed for treating the donor site wounds based on the defect size and local tension. For wounds with low tension, primary closure was performed. For wounds with high tension, the wound edges were appropriately pulled together during operation, and either direct closure or split-thickness skin grafting from the opposite thigh was carried out after the postoperative edema subsided. Phase Ⅱ-Stage 3 (the only stage): 7 to 30 weeks after injury (with mean of 15.8 weeks), the antibiotic bone cement was removed, the volume of bone defect was measured, and the iliac crest bone was harvested precisely, mixed with vancomycin, and used to fill the bone defect; the induced membrane and skin soft tissue were then sutured. Postoperative flap survival and infection-related complications at different stages were recorded. During follow-up, flap appearance and texture, scar condition at the donor and recipient sites, and bone healing were documented. At the last follow-up, the affected foot function was assessed using the foot and ankle ability measure (FAAM) scale, and the percentage of recovery in daily living ability was calculated. Patient health outcomes were assessed using the 36-item short form health survey (SF-36), and the scores of the physical component summary (PCS) and mental component summary (MCS) were calculated. Results Complete flap survival was achieved in 30 patients after operation. Partial flap necrosis occurred in 3 patients, among whom 1 case healed by direct suture after debridement, and 2 cases healed by skin grafting after debridement. Infection-related complications occurred in 4 patients, including superficial infection in 3 cases (1 case after Stage 2 in Phase Ⅰ, 2 cases after Stage 3 in Phase Ⅱ), all of which were controlled after debridement with wound healing. Bone infection occurred in 1 case (after Stage 2 in Phase Ⅰ), which was controlled after repeated thorough debridement and antibiotic bone cement packing, and bone grafting healed. The follow-up period ranged from 12 to 57 months (with mean of 26.7 months). All flaps showed good color and texture. Scar hyperplasia at the flap donor site occurred in 3 cases, while only linear scars remained at the recipient site. At final follow-up, the FAAM scale score of the affected foot was 71±4, and the recovery of daily living ability reached (85±5)%. The PCS score on the SF-36 was 78±4, and the MCS score was 70±11. Conclusions Applying the orthoplastic principle for treating Gustilo type ⅢB open ankle joint fractures results in low infection and other complication rates, along with satisfactory functional recovery of the ankle joint. -
