腕管内压测量及其临床意义

Carpal tunnel internal pressure measurement and its clinical significance

目的探讨腕管综合症的发病原因,寻找治疗腕管综合症的最佳方法。方法利用通过造改的血压测量器,测量腕管在碗横韧带上、下方的内压;观察测量腕横韧带的厚度。结果腕管内压力在韧带上方左侧为(1.39±1.14)mmHg,右侧为(1.81±0.72)mmHg,在韧带下方左侧为(3.02±1.12)mmHg,右侧为(3.15±1.23)mmHg;腕横韧带的厚度为(0.13±0.06)mm。切断腕横韧带后用此种压力测量器尚未测出腕管内压。结论腕管内压的维持与腕横韧带的厚度有一定关系,某种因素造成腕横韧带的增厚是腕管综合症的发病原因之一。

Objective To research into the etiology of carpal tunnel syndrome and seek for the best therapy.Methods The internal pressure of carpal tunnel above and under transverse carpal ligament were measured by blood pressure monitor and the thickness of transverse carpal ligament was observed.Results The internal pressure of carpal tunnel was（1.39±1.14）mmHg and（1.81±0.72）mmHg above the ligament while it was（3.02±1.12）mmHg and（3.15±1.23）mmHg below the ligament.The thickness of transverse carpal ligament was（0.13±0.06）mm.No results of internal pressure could be detected by this blood pressure monitor after cutting off transverse carpal ligament.Conclusion The internal pressure of carpal tunnel is connected with the thickness of transverse carpal ligament.The factor that makes transverse carpal ligament thicker is one of the inducing factors of carpal tunnel syndrome.
