title: Limited wrist arthrodesis: a laboratory study.
abstract: By means of an external fixator, 11 limited wrist "fusions" in eight freshly frozen cadaver wrists were studied. An electrogoniometer measured perfusion and postfusion range of motion, and the percentage of loss of motion was determined and then averaged for all eight wrists. The three fusions that crossed the radiocarpal row lost approximately 55% flexion/extension (F/E). The five fusions that crossed the intercarpal row lost approximately 27% F/E, and the three fusions within a single carpal row lost approximately 12% F/E. These results may be helpful to determine which limited wrist fusion to perform.
