2. Objective To discuss the etiology of lunate avascular necrosis. 目的探讨月骨无菌性坏死的病因。
3. Methods Cryopreserved allogeneic lunate bone transplantation was applied to 6 cases of aseptic lunate osteonecrosis who were followed up more than 10 years. 方法应用深低温冷冻同种异体月骨移植治疗月骨无菌性坏死6例,随访10年以上。
4. It could be considered that the lunate and triquetral bones play a key part in this complex injury, being the basis of the axial burst dislocation of carpal bones. 在这种复杂的病变中月骨和舟骨起着关键的作用,亦是腕骨轴向崩解的基础。
5. Methods After the study of functional anatomy of wrist joint and intra-lunate micro-structure and wrist X-ray, we put forward the factors contributing to lunate avascular necrosis. 方法通过对腕关节机能解剖、月骨内微组织结构及腕关节X线影像学的研究,阐明月骨无菌性坏死的致病因素。
