We measured intracarpal canal pressures with the wick catheter in fifteen patients with carpal tunnel syndrome and in twelve control subjects. The mean pressure in the carpal canal was elevated significantly in the patients. When the wrist was in neutral position, the mean pressure was thirty-two millimeters of mercury. With 90 degrees of wrist flexion the pressure increased to ninety-four millimeters of mercury, while with 90 degrees of wrist extension the mean pressure was 110 millimeters of mercury. The pressure in the control subjects with the wrist in neutral position was 2.5 millimeters of mercury; with wrist flexion the pressure rose to thirty-one millimeters of mercury, and with wrist extension it increased to thirty millimeters of mercury. Carpal tunnel release brought about an immediate and sustained reduction in pressure.
我们用灯芯导管测量了15例腕管综合征患者和12名对照者的腕管内压力。患者腕管内的平均压力显著升高。当手腕处于中立位时，平均压力为32毫米汞柱。手腕屈曲90度时，压力升至94毫米汞柱，而手腕伸展90度时，平均压力为110毫米汞柱。对照者手腕处于中立位时的压力为2.5毫米汞柱；手腕屈曲时压力升至31毫米汞柱，手腕伸展时压力增至30毫米汞柱。腕管松解术使压力立即且持续降低。
