Computed tomography analysis was conducted in 29 patients with 34 carpal canal syndromes to determine structural modifications of the wrist during the immediate preoperative period and two and three months after operation. The carpus was analyzed at 3 levels of the section: proximal at the entrance orifice of the canal, median and distal at the orifice of exit, with the wrist at rest and then in maximum active flexion and extension. Results showed that the increase of canal caliber (and therefore the decrease in local increase in pressure) continued during the second and third postoperative months, at rest as well as in flexion or extension. It appears, further, that opening of the canal does not alter structural organization of wrist bones or ligaments, the increases in caliber obtained varying in the same sense whatever the position of the wrist or the level of the section.
对29例患有34处腕管综合征的患者进行了计算机断层扫描分析，以确定术前即刻以及术后两个月和三个月时手腕的结构变化。在腕管的3个截面水平对腕骨进行分析：在腕管入口近端、出口处的中部和远端，分别在手腕休息时以及最大主动屈伸时进行分析。结果显示，术后第二个月和第三个月期间，无论手腕处于休息状态还是屈伸状态，腕管管径均持续增加（从而局部压力增加减小）。此外，腕管开放似乎并未改变腕骨或韧带的结构组织，无论手腕位置或截面水平如何，管径增加的方向均相同。
