Fifty-three of 55 consecutive elbow replacements for post-traumatic arthritis were followed for a minimum of two years (mean 6.3, range 2 to 14.4). The patients presented difficult management problems, having undergone an average of two previous operations per joint; 22 joints had suffered prior complications; 18 had less than 50 degrees of flexion and six were flail. One of three versions of the Coonrad prosthesis was employed in all. During the follow-up period, 10 patients underwent 14 revision procedures for aseptic loosening; 38 elbows are currently without progressive radiolucent lines. In two patients an elbow had to be resected, one for deep infection and the other for bone resorption following a foreign-body reaction to titanium. The current design of the Coonrad prosthesis offers a reliable option for the treatment of post-traumatic arthritis but should be used only in carefully selected patients over the age of 60 years.
55例因创伤后关节炎行肘关节置换术的患者中，53例接受了至少两年的随访（平均6.3年，范围2至14.4年）。这些患者管理问题棘手，每个关节平均之前接受过两次手术；22个关节曾出现并发症；18个关节屈曲度小于50度，6个关节呈连枷状。均采用了三种版本的Coonrad假体中的一种。随访期间，10例患者因无菌性松动接受了14次翻修手术；目前38个肘关节无进展性透光线。两名患者的肘关节不得不切除，一名是因为深部感染，另一名是因为对钛发生异物反应后出现骨吸收。Coonrad假体的当前设计为创伤后关节炎的治疗提供了可靠选择，但仅应在精心挑选的60岁以上患者中使用。
