From 1984 to 1995, 68 ankylosed elbows and 11 which were unstable after trauma were replaced in India by Baksi sloppy hinge prostheses. The mean age of the patients was 28.6 years (17 to 70) and the mean follow-up 9.6 years (2 to 13.5). Of the 68 ankylosed elbows, 59 (87%) regained a mean arc of painless movement of 88.5 degrees (27 to 115). The mean improvement of supination was 24 degrees and of pronation 16.5 degrees . There were 54 good results (80%), eight fair and three poor. There were two complete failures due to infection, and one due to a broken humeral stem. Of the 11 unstable elbows, the nine with good results had a mean arc of 125 degrees (15 to 140) of painless stable movement, with a mean improvement in supination of 26 degrees and of pronation of 19.5 degrees . There was one fair result and one failure due to loosening with subsequent late infection. There were significant complications in 14 cases with infection in seven and aseptic loosening in four. Patients with loosening or late removal of the prosthesis often retained reasonably stable elbow movement because periprosthetic fibrosis had connected the approximated bone ends, and muscle balance had been restored.
1984年至1995年期间,印度的巴克西简易铰链假体置换了68例肘关节强直病例以及11例创伤后不稳定的肘关节。患者的平均年龄为28.6岁(17至70岁),平均随访时间为9.6年(2至13.5年)。在68例肘关节强直病例中,59例(87%)恢复了平均88.5度(27至115度)的无痛活动弧度。旋后平均改善24度,旋前平均改善16.5度。效果良好的有54例(80%),一般的有8例,差的有3例。有2例因感染导致完全失败,1例因肱骨干断裂失败。在11例不稳定肘关节中,9例效果良好,无痛稳定活动平均弧度为125度(15至140度),旋后平均改善26度,旋前平均改善19.5度。有1例效果一般,1例因松动继发晚期感染而失败。14例出现严重并发症,7例感染,4例无菌性松动。假体松动或后期取出的患者通常仍保留相当稳定的肘关节活动,因为假体周围纤维化连接了接近的骨端,并且恢复了肌肉平衡。
