20 Swanson ulnar head prostheses inserted for post-traumatic disorders of the distal radio-ulnar joint were reviewed at a mean of 44.2 months post-operatively (range 12-104 months). The indication for surgery was painful loss of forearm rotation with or without ulno-carpal impingement and ulno-carpal instability. Symptoms in 16 patients were the result of malunion following severe distal radial fractures (two Frykman 7 fractures and 14 Frykman 8 fractures), and in the remainder were due to unreduced dislocations in the distal radio-ulnar joint (two patients) or unsatisfactory Darrach procedures (two patients). 70% of patients achieved excellent or good clinical results despite the fact that radiographs showed bone resorption in all cases, tilting of the prosthesis in 40% and implant fractures in 15%.
对20例因创伤后桡尺远侧关节疾病而植入Swanson尺骨头假体的患者进行了回顾性研究，术后平均随访44.2个月（范围12 - 104个月）。手术指征为伴有或不伴有尺腕撞击和尺腕不稳的前臂旋转疼痛。16例患者的症状是严重桡骨远端骨折畸形愈合的结果（2例Frykman 7型骨折和14例Frykman 8型骨折），其余患者则是由于桡尺远侧关节脱位未复位（2例患者）或Darrach手术效果不佳（2例患者）。尽管X线片显示所有病例均有骨吸收，40%的假体倾斜，15%的植入物骨折，但70%的患者获得了优良的临床效果。
