Trapeziometacarpal joint contact varies between men and women during three isometric functional tasks

The TMC joint is susceptible to OA, and women are two to six times more likely to develop TMC OA compared to men [1 –3]. Mechanical factors such as contact forces and contact area are likely to be important contributors to the onset, progression, and sex-disparity of TMC OA [4–6]. Prior studies hypothesised that the smaller wrists of women would experience higher stress than men during activities of daily liv ing that require similar overall contact forces, such as pinch, grasp, and jar twist, due to smaller contact areas [6–9].
