Earlier generations of wrist arthroplasty were limited to low demand patients. Bone fixation problems, excessive wear, and adverse designs resulting in loosening, imbalance, and dislocation led to the withdrawal of a number of models. Contemporary wrist prostheses aim at replacing wrist arthrodesis in the majority of patients with radiocarpal destruction, including high demand cases. Contraindications are wrist imbalance, insufficient soft tissue, or bone stock and infection. Various designs, fixation principles, bearing materials, and articulations have been employed. Some of the devises (RE-MOTIONTM, Motec®) demonstrate promising short- to midterm results, and calls for cautious optimism. [ABSTRACT FROM AUTHOR]
