Since 1978 eighteen patients were treated for Kienböck's disease by the Graner procedure. The satisfactory long-term results can be explained by the preservation of the radiocarpal joint. By restoring fairly congruent joint surfaces, secondary radiocarpal joint arthrosis, which affects long-term results, may be avoided. Employing Graner's procedure, the authors observed two cases with pseudarthrosis within the intercarpal arthrodesis. They interpret this complication to be a result of micro-movements with the new bone block in the former midcarpal joint level. These movements may be avoided by careful removal of all the cartilage from all joint parts which are to be fused.
自1978年以来，18例月骨无菌性坏死患者接受了格拉纳手术治疗。长期效果令人满意，这可以通过保留桡腕关节来解释。通过恢复相当一致的关节面，可以避免影响长期效果的继发性桡腕关节关节炎。采用格拉纳手术时，作者观察到两例腕骨间融合处出现假关节的病例。他们认为这种并发症是由于在前中腕关节水平新骨块存在微运动所致。通过仔细去除所有待融合关节部位的软骨，可以避免这些运动。
