Objective To discuss the etiology of lunate avascular necrosis.

目的探讨月骨无菌性坏死的病因。

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。

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。

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。
