Kienböck's disease is probably caused by microfractures or stress fractures developing within the lunate. In about 32% of the population, the vascular pattern to the lunate is such that after fracture they are vulnerable to a secondary aseptic necrosis of the lunate. The high incidence of Kienböck's disease in patients with an ulnar minus variant wrist may be explained by an increased stress on the lunate in dorsiflexion and ulnar deviation. This study is a 5- to 10-year follow-up of patients with early stages of Kienböck's disease and ulnar minus variant treated by radial shortening procedures. Eleven of the 12 patients were satisfied with their treatment and showed functional improvement. These patients returned to their normal activities. Grip strength was satisfactory, and range of motion improved following surgery.
月骨无菌性坏死可能是由月骨内的微骨折或应力性骨折引起的。在大约32%的人群中，月骨的血管分布情况使得骨折后易发生月骨继发性无菌性坏死。尺骨负变异腕关节患者中月骨无菌性坏死的高发病率，可能是由于背伸和尺偏时月骨所受应力增加所致。本研究是对采用桡骨缩短术治疗的早期月骨无菌性坏死和尺骨负变异患者进行的5至10年随访。12例患者中有11例对治疗满意，功能得到改善。这些患者恢复了正常活动。握力令人满意，术后活动范围也有所改善。
