To study the value of postoperative splinting after open carpal tunnel surgery, we randomly selected 82 wrists for 4 weeks of postoperative immobilization or no immobilization. The distributions of scar discomfort or pain and "pillar pain" were equal in the two groups both at 6 weeks and 6 months. Median sick leave was 6 weeks in both groups. Median VAS values for persistent discomfort and pain at 2 weeks, 6 weeks and 6 months were similar in the two groups. Grip strength was reduced compared to preoperative values by about 20% and keypinch strength by about 10% in both groups at 6 weeks and had returned to normal by 6 months. Pinch between the thumb and the tips of fingers 4 and 5 was considerably reduced postoperatively, but similar in both groups. We conclude that 4 weeks of postoperative immobilization confers no detectable benefit.
为研究开放性腕管手术后使用术后夹板固定的价值，我们随机选取了82例手腕，分别进行4周的术后固定或不固定。在术后6周和6个月时，两组的瘢痕不适或疼痛以及“柱状疼痛”的分布情况相同。两组的病假中位数均为6周。两组在术后2周、6周和6个月时持续不适和疼痛的视觉模拟评分（VAS）中位数相似。两组在术后6周时握力较术前值降低约20%，捏力较术前值降低约10%，至6个月时恢复正常。拇指与示指和中指指尖之间的捏力术后明显降低，但两组相似。我们得出结论，术后4周的固定未显示出可检测到的益处。
