Clinical trials with cemented polyethyiene and metal total joint arthroplasties were initiated in 1973. Replacements have been developed for the wrist, carpometacarpal joint of the thumb, metacarpophalangeal joints of the thumb and fingers, and the proximal interphalangeal joints of the fingers. Results, evaluated by pain relief and joint stability, were excellent at all sites. Motion, however, averaged only 50% of normal. Significant problems included abnormal posture in the wrist, roentgenographic evidence of loosening in the finger metacarpophalangeals, extensor lag in the metacarpophalangeal of the thumb, and lack of motion in the proximal interphalangeal joint of the finger.
1973年开始了关于骨水泥聚乙烯和金属全关节置换术的临床试验。已开发出用于腕关节、拇指掌腕关节、拇指和手指的掌指关节以及手指近端指间关节的置换物。通过疼痛缓解和关节稳定性评估的结果在所有部位都非常好。然而，活动度平均仅为正常的50%。重大问题包括腕部姿势异常、手指掌指关节松动的X线证据、拇指掌指关节伸肌滞后以及手指近端指间关节活动受限。
