吻合血管腓骨移植治疗股骨头缺血坏死

临床观察吻合血管腓骨移植治疗成人股骨头缺血坏死520例，其中有创伤史229例，服用激素药物史者228例，有酗酒史者34例，原因不明者29例。术后315例获得1～15年随访，结果提示，优良率为86．6％。手术切开说关节囊，在彻底清除股骨头内骨坏死囊变组织的同时，植入新鲜自体松质骨并在股骨头颈部前外侧植入吻合血管的腓骨。该手术增加了股骨头部血液供给，充分减轻了股骨头内压力，加之腓骨为坚质骨，来后不易吸收，对股骨头颈部起到了支撑作用，防止了股骨头进一步塌陷。     

吊带疗法对并发于先天性髋脱位的股骨头坏死的作用

采用带蹬吊带体系治疗婴幼儿先天性髋脱位１５５例１９９髋。对治疗过程中所出现的２２例３０髋股骨头坏死，进行了２～９年连续观察发现：吊带疗法和石膏固定疗法在治疗过程中虽然都有股骨头坏死出现，但头坏死的情况截然不同，前者明显优于后者，吊带疗法有防止、减轻和治疗股骨头坏死的作用。     

吻合血管腓骨移植在股骨头颈部的生长变化

作者对1981～1989年112例股骨头无菌性坏死及陈旧性股骨颈骨折施行了股骨头颈部自体吻合血管的游离腓骨移植术。对其中44例进行了3个月～8年随访发现:带血管的腓骨移植到股骨头颈部后,在生长过程中逐渐改建塑形,将自身的形态结构转变成为类似股骨头颈部骨骼的形态与结构,以适应新的环境及功能。此过程约需3年～4年。     

吻合血管腓骨移植重建股骨头血供实验研究

本文采取自身对照方法对18条成熟体健雄性家犬的36侧股骨头颈部、分为两组、分别制成陈旧性股骨颈骨折和股骨头缺血性坏死模型。两周后进行吻合血管腓骨移植,术后分别进行X线片、病理组织学、电镜、99~m锝-亚甲基二膦酸盐骨扫描和四环素荧光标记等观察。实验结果表明:吻合血管腓骨移植为损伤股骨头提供了新的血供系统。坚硬的游离腓骨和金属内固定同时插入股骨头颈部,术后腓骨在骨折区形成骨桥,不仅能消除剪力,而且防止骨折断端旋转移位。移植腓骨骨膜也参与了股骨头缺血性坏死的修复过程。     

Automatic outer surface extraction of femoral head in CT images

Computer-aided hip surgery planning and implant design applications require accurate segmentation of femoral head and proximal acetabulum. An accurate outer surface extraction of femoral head using marching cubes algorithm remains challenging due to deformed shapes and extremely narrow inter-bone regions. In this paper, we present an automatic and fast approach for segmentation of femoral head and proximal acetabulum which leads to accurate and compact representation of femoral head using marching cubes algorithm. At first, valley-emphasized images are constructed from original images so that valleys stand out in high relief. Otsu’s multiple thresholding technique is applied to seperate the images into bone and non-bone classes. Region growing method and threedimensional (3D) morphological operations are performed to fill holes in the bone. In the reclassification process, the bone regions are further segmented, and the boundaries of the bone regions are further refined based on Bayes decision rule. Finally, marching cubes algorithm is applied to reconstruct a 3D model and extract the outer surface of femoral head and proximal acetabulum. Experimental results show that this method is an accurate segmentation technique for femoral head and proximal acetabulum and it can be applied as a tool in medical practice.     

实验性股骨头骨缺损修复过程的生物力学研究

目的　对股骨头内骨缺损自然修复过程进行分析、评价。方法　本实验分脱位组、未脱位组及正常组 ,对犬股骨头内骨缺损修复过程进行计量组织学及生物力学研究。结果　脱位组股骨头均塌陷 ,未脱位组囊腔硬化带形成 ,两组囊腔均未完全闭合。脱位组的骨小梁体积及软骨下骨厚度、软骨下骨生物力学特性均较正常组及未脱位组低。脱位组松质骨的抗压强度及弹性模量较未脱位组低。结论　股骨头脱位可致股骨头坏死塌陷 ,股骨头塌陷与软骨下骨的生物力学特性及厚度有关 ,后两者间亦存相关关系。囊腔硬化带形成是一种代偿反应 ,但可产生应力遮挡 ,不利于囊腔闭合。

股骨头内松质骨移植观察

目的　了解股骨头内松质骨移植后的病理变化 ,为股骨头坏死治疗提供理论基础。方法　 80只日本白兔分实验组 (股骨头内骨质刮除 ,自体松质骨移植 )和对照组 (股骨颈骨折后原位内固定 ) ,进行病理组织学、X线和血管造影观察。结果　松质骨移植后股骨头可完全修复 ,且较对照组效果好。结论　髓腔血供可修复股骨头 ,故提供血管修复的环境很重要 ,而股骨头坏死治疗中血管植入可能只起加快修复作用     

松质骨加bBMP治疗Legg-Perthes病实验研究

目的　评价自体松质骨加bBMP移植对实验性Legg Perthes病动物股骨头的修复作用。方法　用TH胶股骨颈内注射法将 1 2只幼犬共 2 4髋制作Legg Perthes病模型 ,3个月后动物随机平均分为自然修复组A ,自体松质骨移植组B和松质骨加bBMP植入组C ,术后 4、8周观察不同方法的治疗效果。结果　A组所有股骨头变扁 ,骨质生长不良。B组股骨头高度明显低于术前 ,股骨头内修复范围有限。C组股骨头高度手术前后无明显变化 ,骨质生长良好 ,修复较完全。结论　松质骨加bBMP能促进幼犬股骨头修复 ,防止塌陷发生 ,是Legg Pethes病治疗的好方法。
