Abstract

Osteoarthritis (OA) of the thumb carpometacarpal (CMC) joint is a common and disabling condition. Controversies surround the etiology of CMC OA because the internal mechanics of the joint is poorly understood. Several studies have been reported where mathematical modeling was used to study the biomechanical behavior of the CMC joint. Cooney et al (1977) developed a 3D static thumb model. An et al (1985) modified this model to simulate abnormal conditions of the thumb such as tendon laceration. Esteki (1995) developed a dynamic model to study neuromuscular stimulation of the hand. However, these previous studies have mostly employed idealized kinematic representations of the CMC joint (e.g., as a universal joint), and their results have focused primarily on the calculation of joint reactions forces. The biomechanical parameters which are believed to play key roles in CMC joint degeneration, such as contact area patterns of articular surfaces and complex higher pair kinematics, cannot be predicted by these models. Moreover, Imaeda Ct al (1994) demonstrated that the CMC joint may not be adequately modeled as a universal joint, emphasizing the need for employing the actual geometry of CMC articular surfaces for kinematic analyses.
