半关节重建术后持续被动运动

Continuous Passive Motion after Semijoint Re-constrution

１９８９～１９９３年共有６８例骨肿瘤在本院行大块切除，并以异体骨或灭活的自体瘤骨行半关节重建术，根据术后处理情况将这些病人分为二组，一组术后关节外固定４～６周，而另一组术后即接受ＣＰＭ（持续被动运动），经过５个月～４年的随访，发现ＣＰＭ组膝关节（２０例）平均屈曲度比固定组（２１例）大５０°（Ｐ值（０．００１）。根据本研究结果，作者认为ＣＰＭ具有（１）预防或克服重建关节的强直，（２）不妨碍创口、韧带和肌腱的愈合，（３）病人相对无痛苦。

AbstractBetween 1989 and 1993,68 cases of bone tumorswcre trcatcd by massive resection and scmijoint reco-struction using allograft or autograft devitalized tumorbones, These patients were divided into two groupsaccording to postoperative management,the firstgroup consisted of 37 cases who had postoperative theimmobilization for 4～6weeks, and the other 31 casesreceived CPM in the immediate postoperative periodfor 7～10 days。Through 5 months to 4 years of fol-low-up study, the mean range of flexion in CPM treat-ed knees(20 Knees)was 50° more (P<0.001) thanthat in the immobliised knees(21 Knees)。In the present investigation,the authors believedthat CPM started immediately postoperatively in thepatients treated by semijoint, had the foIlowing advan-tages(1) CPM prevented Or overcome the joint stiff-ness,(2)It did not interfere the wound, tendon andligament healing and(3) the patients were relativelyfree from pain。
