摘要:

文题释义:
诱导膜技术:是修复骨缺损,尤其是感染性骨缺损的有效方法。手术分二个阶段,第一阶段手术是在骨缺损部位填塞骨水泥,由于异物反应刺激周围软组织形成伪膜,伪膜逐渐增厚成为诱导膜;第二阶段手术是切开诱导膜取出骨水泥填塞物,在诱导膜内植入松质骨等植骨材料,并缝合诱导膜。第二阶段手术时间因骨缺损部位是否感染和感染何时得到控制而不同。
诱导膜包裹松质骨植骨修复骨缺损的机制:一方面是诱导膜具有机械性的隔离和包裹作用;另一方面诱导膜是生物膜,具有生物性成骨活性。诱导膜厚度可达1 mm左右,比正常骨膜更厚,外层主要为纤维组织,具有机械性隔离纤维组织长入骨缺损部位作用。

背景:对于骨缺损的治疗,早期与晚期阶段行诱导膜内植骨修复的骨愈合效果可能存在差异。

目的:探讨早期与晚期阶段行诱导膜内植骨修复骨缺损的愈合效果差异和影响骨愈合的主要因素。

方法:选择2007年1月至2017年8月无锡市骨科医院和无锡市人民医院行诱导膜技术治疗的63例胫骨骨缺损患者,其中男38例,女25例,年龄16-69岁,按骨水泥填塞后诱导膜内植骨时机不同分为2组:早期组(n=25)在骨水泥填塞后6-8周诱导膜内植骨,晚期组(n=38)在骨水泥填塞后10-12周诱导膜内植骨。随访评估两组骨缺损愈合与患肢功能恢复情况,分析发生延迟愈合和骨不连的原因。试验获得无锡市人民医院和无锡市骨科医院医学伦理委员会审批(LW2019001)。

结果与结论:①63例患者均顺利完成骨移植手术,术中发现早期组形成的诱导膜较薄、毛细血管相对较多,而晚期组形成的诱导膜通常较厚、毛细血管相对较少;②63例获得16-50个月随访;早期组伤口或切口一期愈合22例,延期愈合3例;晚期组伤口或切口一期愈合34例,延期愈合2例,二期愈合2例;③早期组延迟愈合1例,无骨不连病例,临床愈合时间5.0-12.0个月,平均6.64个月;晚期组延迟愈合2例,骨不连1例,临床愈合时间5.0-16.0个月,平均7.42个月;两组骨缺损愈合时间、骨不连发生情况比较差异无显著性意义(P > 0.05);④早期组患肢功能恢复:优13例、良11例、可1例,晚期组患肢功能恢复:优17例、良18例、可3例,两组患肢功能恢复情况比较差异无显著性意义(P > 0.05);⑤结果表明,不同时期行诱导膜内植骨对骨缺损骨愈合时间有一定影响,但影响较小,对愈合率无影响,而诱导膜体积和完整性、植骨质量和数量及断端稳定性等其它因素对骨缺损骨愈合,尤其是愈合率的影响更大。

Abstract:

BACKGROUND: It remains unclear regarding the difference in bone healing effects after early-stage versus late-stage bone grafting within induced membrane.

OBJECTIVE: To investigate the difference in bone healing effects of bone grafting within induced membrane in the repair of bone defects and the major factors that affect bone healing.

METHODS: Sixty-three patients with tibial bone defect who received treatment with induced membrane technique during January 2007 to August 2017 in Wuxi People’s Hospital and Wuxi Orthopedics Hospital, China. These patients consisted of 38 males and 25 females and were aged 16-69 years. According to the time of bone grafting within induced membrane after bone cement filling, these patients were divided into an early stage group (n=25, bone grafting in the induced membrane 6-8 weeks after filling bone cement) and a late stage group (n=38, bone grafting in the induced membrane 10-12 weeks after filling bone cement). The healing of bone defect and functional recovery of affected limbs were evaluated. The causes of delayed healing and nonunion were analyzed. This study was approved by the Medical Ethics Committee of Wuxi People’s Hospital and Wuxi Orthopedics Hospital, China (approval No. LW2019001).

RESULTS AND CONCLUSION: Bone graft was successfully completed in 63 patients. The induced membrane formed in the early stage group was thin and there were relatively more capillaries, while the induced membrane formed in the late stage group was usually thick and there were relatively few capillaries. All 63 patients were followed up for 16-50 months. In the early stage group, the wound or incision healed at first intention in 22 patients and delayed healing was observed in 3 patients. In the late stage group, the wound or incision healed at first intention in 34 patients, delayed healing was observed in 2 patients, and healing by the second intention was observed in 2 patients. In the early stage group, there was 1 patient developing delayed healing, no nonunion was observed, the clinical healing time was averaged 6.64 (range 5.0-12.0 months) months. In the late stage group, delayed healing occurred in 2 patients and nonunion was observed in 1 patient. The clinical healing time was averaged 7.42 (range 5.0-16.0 months) months. There were no significant differences in the healing time and nonunion between the early stage and late stage groups (P > 0.05). In the early stage group, excellent functional recovery of affected limb was observed in 13 patients, good recovery in 11 patients, and fair recovery in 1 patient, and it was 17, 18 and 3 patients respectively in the late stage group. There was no significant difference in functional recovery of affected limbs between early stage and late stage groups (P > 0.05). These results showed that bone grafting within the induced membrane at different time has slight, but not significant effect on healing of bone defect. Other factors, such as the size and the integrity of induced membrane, the quality and quantity of bone graft material, and the stability of bone stumps had more significant effects on the healing of bone defects, in particular on the healing rate.
