Compression-staple fixation for fractures, non-unions, and delayed unions of the carpal scaphoid.
We used the Richards scaphoid compression staple for operative fixation in a total of twenty-five patients who had a fracture of the carpal scaphoid: sixteen whom we reported on previously and nine whom we are reporting on for the first time here. In the current series, we extended the application of the method to fresh, unstable fractures (two patients) and treated an additional seven patients who had a non-union or delayed union. The procedure was simple, and no operative complications were encountered. Both patients who had a fresh fracture had a satisfactory result. Of the other twenty-three patients, only two had a result that was not satisfactory. One patient had a persistent non-union. Three patients had doubtful radiographic evidence of a persistent non-union; however, all three had a good result clinically, and only one had moderate loss of function. Although the over-all results were good, there was some worsening of the clinical results on long-term follow-up compared with those that we reported earlier. This deterioration probably was due to secondary degenerative changes in the articular surfaces.
