文题释义:
包裹植骨:是改良的松质骨游离植骨方法,指包裹装置包裹自体松质骨的植骨。包裹装置具有机械性包裹作用,增加了植骨材料稳定性,同时包裹结构具有网孔和生物属性,不妨碍松质骨从周围获取营养和血供,也不妨碍骨痂生长和骨痂连接。
联合取骨:从人体2个或2个以上部位切取自体骨,作为植骨材料的取骨方法。
包裹植骨的优势:包裹结构对植骨材料有机械性包裹固定作用,使植骨材料与断端、内固定器紧密连接成在一起,提供植骨材料良好稳定性,避免了周围肌腱或肌肉收缩时滑动刺激和震荡挤压等导致的植骨材料松动;②包裹结构有孔道,不妨碍植骨材料从周围获取营养和血供,也不妨碍骨痂生长和连接;③联合取骨的植骨量较多,而且强调植骨材料为自体松质骨为主,而松质骨成骨效果较好;④因为有包裹结构,植骨材料的稳定性较好,术后可早期康复锻炼,无需外固定,而早期康复锻炼有益于刺激骨折愈合和关节功能恢复。
 
 
背景:包裹植骨可治疗大段骨缺损,但包裹植骨治疗大段骨缺损需要大量自体松质骨,如何获取大量自体松质骨仍是临床研究课题。
目的:探讨联合取骨行包裹植骨治疗大段骨缺损的效果。
方法:回顾分析21例四肢长骨大段骨缺损患者的临床资料,其中男15例,女6例,年龄15-69岁,均进行自体联合取骨行包裹植骨治疗,从髂后、胫骨近端或髂前等部位联合切取丰富松质骨,其中采用诱导膜包裹植骨材料9例、钛网包裹植骨材料7例、线网包裹植骨材料5例。随访观察患者骨愈合、患肢功能恢复、邻近关节活动度和并发症情况。
结果与结论:①随访12-51个月,诱导膜包裹者临床愈合时间平均6个月,钛网包裹者平均6.29个月,线网包裹者平均6.6个月;②末次随访,骨缺损愈合分级评估,优20例、良1例;患肢功能恢复评估,优7例、良9例、可4例、差1例,优良率为76%;邻近关节活动度评估,优8例、良9例,可3例、差1例,优良率为81%;③植骨区并发症4例,取骨区并发症3例,无内固定器断裂和再骨折;④结果表明,联合取骨可满足大段骨缺损需要大量自体松质骨的需求,行包裹植骨治疗的骨愈合率高、愈合较快,并发症较少。

Abstract:

BACKGROUND: Encapsulated bone graft is considered suitable for the treatment of large-segmental bone defects, but a large volume of autogenous cancellous bone tissues is needed and how to harvest cancellous bone is still an issue of clinical research.

OBJECTIVE: To investigate the effect of encapsulated bone graft by united procurement for repair of large-segmental bone defects.
METHODS: Clinical data from 21 cases of large-segmental bone defects treated with encapsulated autologous bone grafts were retrospectively analyzed. There were 15 males and 6 females, aged 15-69 years. Rich cancellous bone was harvested from the posterior iliac, proximal tibia or anterior iliac. Encapsulation of bone grafts using osteoinduction membrane, titanium mesh and wire mesh was conducted in 9, 7, and 5 cases, respectively. Bone healing, functional recovery of affected limbs, range of motion of adjacent joints and complications were observed during follow-up period.

RESULTS AND CONCLUSION: During the follow-up of 12-51 months, the average time for bone healing was 6 months for encapsulation using osteoinduction membrane, 6.29 months for encapsulation using titanium mesh, and 6.6 months for encapsulation using wire mesh. At the last follow-up, bone healing was excellent in 20 cases and good in 1 case; the functional recovery of the affected limb was excellent in 7 cases, good in 9 cases, fair in 4 cases and poor in 1 case, with the excellent and good rate of 76%. The range of motion of adjacent joints was excellent in 8 cases, good in 9 cases, fair in 3 cases and poor in 1 case, with the excellent and good rate of 81%. Complications in grafting sites were noted in 4 cases, and complications in harvesting sites were noted in 3 cases. These findings indicate that united harvesting of bone tissues can meet the requirement for a large volume of autogenous cancellous bone in the repair of large-segmental bone defects. Encapsulated bone graft has high healing rate, fast healing as well as few complications.
