同种脱钙骨粉移植治疗骨缺损的初步报告 总被引:8,自引:1,他引:7
我院在同种脱钙骨移植的动物实验的基础上,于1983年以来用同种脱钙骨粉移植修复因骨伤、病及肿瘤切除后的骨缺损52例,其中四肢骨43例,面颌口腔部9例,除1例慢性化脓性骨髓炎术后伤口感染外,其余病例均一期愈合。多数病例是3个月以内手术的,尚在观察中。对三个月以上到一年半随访的12例进行了分析和讨论。从52例的近期疗效看,脱钙骨粉消毒可靠,未见明显的排斥反应。12例随访的病例,在3—6个月以内均有不同程度的骨化,成骨效应是满意的。其主要优点是不需由患者自身取骨,使用、保存方便,可以商品化,是一种良好的修复骨缺损的材料。 相似文献

This experiment was designed to evaluate the osteogenetic effects ofdifferent forms of allogenic decalcified bone matrix.39 rabbits were em-ployed and a bony defect of 1cm in length was made on the shaft of theulnas of the animals.They were divided into 4 groups.In the first group,the bony defects were filled with allogenic decalcified bone powder,in thesecond group,with decalcified bone blocks,in the third group,with unde-calcified bone blocks,and in the fourth group,nothing was filled into thebony defects.Roentgenological and histological studies were made regularly.It was found that after 8-10weeks,70-80% of the bony defects filledwith DBM showed firm union between the host bone and the graftedmaterial and no difference of the osteogenecity could be found between thetwo kinds of DBM,incomplete union occurred in the third group,andnonunion was seen in the fourth group.It is suggested that allogenic decalcified bone powder be used as a graftma-terial to fill up bony defects or cavities because it is easily preparedand used,has good plasticity,and can be stored in room temperature. 相似文献

同种脱钙骨粉和骨块移植的实验观察 总被引:3,自引:0,他引:3
为证实不同形式的脱钙骨基质(DBM)及未脱钙骨的成骨作用进行了本实验。我们采用家兔39只,分为四组:(1)脱钙骨粉组;(2)脱钙骨块组;(3)未脱钙组;(4)空白组。将兔尺骨干造成1cm缺损后植入上述不同DBM及未脱钙骨,定期行X线及组织学观察。实验结果显示两种形式的DBM,在第8—10周标本的骨愈合率为70—80%,二者无明显差别。但未脱钙骨组在第8—10周标本只有部份连接。空白组在第10周无骨连接。以上结果表明DBM的成骨效应较未脱钙骨为优。骨粉制备简单,使用保存方便,可塑性强,作为骨移植材料填充骨腔是可行的。 相似文献

带旋髂深动静脉蒂的髂骨片转位移植治疗陈旧性股骨颈骨折骨不连(附4例报告) 总被引:1,自引:1,他引:0
本文初步报道,采用带旋髂深血管蒂的髂骨片转位移植,治疗股骨颈骨折不连4例。手术方法的设计是依据对尸体解剖的髂骨嵴血供的研究,证实髂骨嵴前部的血供来源于旋髂深血管。本文对手术方法作了详细介绍,认为该血管解剖关系恒定,较表浅而易于手术显露。血管蒂较长,便于骨块转位移植,同时血管口径亦较粗。供骨区可以取大量骨块,并能保持充足的血液供应。本组4例股骨颈骨折不连,术后4~6个月骨折均已完全愈合,随访10~18个月患肢功能恢复较满意。术后半年,1例行动脉造影证明供血充分,1例行骨扫描检查证明股骨头供血良好。 相似文献
