Wrist arthroplasty has now become a predicable procedure for a range of wrist pathologies, with procedural risks declining with design developments. It is a procedure that is an alternative to arthrodesis for managing advanced wrist arthritis while preserving motion. The concept and design was pioneered in the 1990 with Themistocles Gluck’s ivory and metal prostheses, however early attempts were unsuccessful due to poor fixation and biomechanical understanding. Modern wrist arthroplasty began in the 1960s with silicone interpositional implants introduced by Swanson, which provided pain relief but were associated with implant fracture and silicone synovitis. Subsequent generations incorporated metal-on-polyethylene articulations and modular designs such as the Meuli, Volz, and Biaxial prostheses to enhance stability and motion.. Advances in materials and cementing techniques led to fourth-generation implants such as the ReMotion and Maestro, designed to replicate native kinematics while reducing loosening and subsidence.
Despite progress, complications remain common, including carpal component failure and limited load tolerance, leading arthrodesis to remain preferred for younger or high-demand patients. Nonetheless, contemporary prostheses demonstrate encouraging outcomes for pain relief and functional preservation in low-demand or rheumatoid arthritis patients (Nydick et al., 2012). Emerging developments in additive manufacturing and patient-specific implants promise further refinement in restoring physiological motion.
