本研究的目的是探讨腕管压力变化对松解后腕管形态的影响。腕管综合征患者的腕管内压力升高，并取决于手腕姿势。以前，增加腕管压力被证明会影响腕管的形态与完整的腕横韧带。然而，腕横韧带松解后腕管的压力-形态关系尚未研究。在内窥镜下对尸体手进行腕管松解术（CTR），腕管压力从10 mmHg动态增加到120 mmHg。同时，通过超声系统捕获腕管横截面图像，并通过压力传感器记录压力测量值。发现腕管压力显著影响腕弓面积（p<0.001），在120 mmHg时增加>62 mm 2。腕弓的高度、长度和宽度也随着腕管压力的变化而变化（p<0.05）。随着腕管压力的增加，腕弓的高度和长度增加，而腕弓的宽度减小。对释放的腕管的压力-形态关系的分析显示，与先前报道的完整腕横韧带的腕管相比，其顺应性高9倍。由于横断腕横韧带而导致的结构特性的这种变化有助于解释CTR手术后患者腕管压力的降低和症状的缓解。
The purpose of this study was to investigate morphological changes of a released carpal tunnel in response to variations of carpal tunnel pressure. Pressure within the carpal tunnel is known to be elevated in patients with carpal tunnel syndrome and dependent on wrist posture. Previously, increased carpal tunnel pressure was shown to affect the morphology of the carpal tunnel with an intact transverse carpal ligament. However, the pressure-morphology relationship of the carpal tunnel after release of the transverse carpal ligament has not been investigated. Carpal tunnel release (CTR) was performed endoscopically on cadaveric hands and the carpal tunnel pressure was dynamically increased from 10 to 120 mmHg. Simultaneously, carpal tunnel cross-sectional images were captured by an ultrasound system and pressure measurements were recorded by a pressure transducer. It was found that carpal tunnel pressure significantly affected carpal arch area (p<0.001), with an increase >62 mm2 at 120 mmHg. Carpal arch height, length, and width were also found to significantly change with carpal tunnel pressure (p<0.05). As carpal tunnel pressure increased, carpal arch height and length increased, but the carpal arch width decreased. Analyses of the pressure-morphology relationship for a released carpal tunnel revealed a nine times greater compliance than that previously reported for a carpal tunnel with an intact transverse carpal ligament. This change of structural properties as a result of transecting the transverse carpal ligament helps explain the reduction of carpal tunnel pressure and relief of symptoms for patients after CTR surgery.
