[Intercarpal pseudarthrosis as a complication of Graner's operation]

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.
