OBJECTIVE To determine the effect of a removable rigid dressing (RRD) on the time to residual limb maturation compared with elastic bandage (EB) in transtibial amputees. DESIGN Experimental single-blinded (assessor-blinded) randomized controlled trial. SETTING Department of Rehabilitation Medicine, King Chulalongkorn Memorial Hospital. PARTICIPANTS Twenty-five transtibial amputees with immature residual limb. INTERVENTIONS Participants were allocated to use RRD or EB to achieve residual limb maturation, and all participants in both groups were trained with the same pre-prosthetic program. MAIN OUTCOME MEASURES The time to residual limb maturation, patient satisfaction and complications were compared between the two groups. RESULTS Median time to residual limb maturation was significantly lower in the RRD group (28 days, IQR: 17-51 days) than in the EB group (54 days, IQR: 30-77 days; P=0.020). After accounting for time since amputation, maturation time remained significantly lower in the RRD group (adjusted HR=3.32, 95%CI: 1.08 to 10.20; P=0.036). There was no significant difference in complications or patient satisfaction. CONCLUSION In post-operative management of transtibial amputation, the use of RRD had a significantly shorter period to residual limb maturation when compared with EB group.

可拆卸硬质敷料和弹性绷带促进胫骨截肢者残肢成熟的比较：一项随机对照试验

目的 与小腿截肢者的弹性绷带 (EB) 相比，确定可拆卸刚性敷料 (RRD) 对残肢成熟时间的影响。设计 实验性单盲（评估者盲）随机对照试验。设置 康复医学科，朱拉隆功国王纪念医院。参与者 25 名残肢未成熟的胫骨截肢者。干预 参与者被分配使用 RRD 或 EB 来实现残肢成熟，并且两组中的所有参与者都接受了相同的假肢前计划培训。主要观察指标比较两组残肢成熟时间、患者满意度及并发症发生情况。结果 RRD 组残肢成熟的中位时间显着降低（28 天，IQR：17-51 天）比 EB 组（54 天，IQR：30-77 天；P=0.020）。在考虑截肢后的时间后，RRD 组的成熟时间仍然显着降低（调整后的 HR=3.32，95%CI：1.08 至 10.20；P=0.036）。并发症或患者满意度没有显着差异。结论在胫骨截肢术后管理中，与EB组相比，RRD的使用显着缩短了残肢成熟的时间。
