title: Trapeziometacarpal arthrodesis: is bone union necessary for a good outcome?
abstract: We present a retrospective study of 107 cases of thumb carpometacarpl joint arthrodesis. The aim of our study was to analyse our population and to compare the outcomes of patients who obtained bone union with the patients who did not. There were no statistical differences in most of the clinical outcomes (DASH score, visual analogue scale, Kapandji test, grip, and key pinch) between the two groups of patients; there were fewer cases of scaphotrapeziotrapezoid arthritis in the group that did not obtain bone union. We conclude that the bone union is not necessary for a good outcome. Level IV of evidence.
