摘要:

背景:含抗生素骨水泥修补骨缺损可在缺损处持续释放较高浓度的敏感药物,利于杀灭致病菌,为二期植骨提供必要的植骨床和植骨空间,减少二期植骨时清除骨缺损处肉芽而引起的大量出血。
目的:分析抗生素骨水泥联合自体骨移植、环形外固定架治疗创伤性骨髓炎后胫骨缺损的临床疗效。
方法:纳入31例胫骨慢性骨髓炎后骨缺损患者,其中男19例,女12例,年龄17-40岁,积极清创骨断端坏死感染组织,以Ilizarov环形外固定支架牢固固定骨折端,取自体髂骨移植骨缺损处修复,同时在缺损处放置含抗生素骨水泥填充支持,随访观察骨折骨性愈合时间、膝关节和踝关节评分情况。
结果与结论:31例获6个月-3.5年随访,胫骨骨折均骨性愈合,无感染复发,骨性愈合时间为3-6个月,外固定时间3-6个月,术后患肢延长长度(7.50±1.01) cm,未发生与骨水泥材料及移植骨材料相关的不良反应。植骨后3个月时的膝关节和踝关节评分均较治疗前明显改善(P < 0.05)。表明抗生素骨水泥联合自体骨移植、环形外固定架治疗骨髓炎后胫骨骨缺损可控制感染的发生,促进骨折愈合,恢复关节功能。

Abstract:

BACKGROUND: Bone cement containing antibiotics for repair of bone defects can achieve sustained release of a higher concentration of sensitive drugs, which will help kill bacteria and provide the necessary bone grafting bed and space to reduce massive bleeding due to removal of the granulation at bone defects during the second phase.
OBJECTIVE: To analyze the clinical efficacy of antibiotic bone cement combined with autologous bone transplantation and Ilizarov external fixator on tibial bone defects after traumatic osteomyelitis.
METHODS: A total of 31 patients with tibial bone defects after chronic osteomyelitis, including 19 males and 12 females, aged 17-40 years old. After positive debridement of necrotic tissues at bone stump, Ilizarov external fixator was used for fracture fixation, and autogenous iliac bone grafting combined with bone cement containing antibiotics was performed to repair bone defects. Fracture healing time, knee and ankle scoring were followed up.
RESULTS AND CONCLUSION: The 31 patients were followed up for 6 months to 3.5 years. Tibial fractures were healed without infection recurrence in all patients. The bony union time was 3-6 months, the fixation time was 3-6 months, and the limb extended length was (7.50±1.01) cm. No adverse reactions related to bone cement and bone graft occurred. At 3 months after bone grafting, the scores on the knee and ankle joints were improve significantly. These findings indicate that the antibiotic bone cement combined with autologous bone transplantation and Ilizarov external fixator for repair of post-osteomyelitis posterior tibial bone defects can control infection, promote fracture healing, and restore joint functions.
