This study was designed to find a possible correlation between the presence of the palmaris longus (PL) tendon and function of the fifth flexor digitorum superficialis (FDS) and carpal tunnel syndrome (CTS).
The CTS and normal groups consisted of 60 and 180 hands, respectively. The diagnosis of CTS was confirmed by detailed history taking, physical examination and electrodiagnostic testing. The presence of the PL tendon and function of the fifth FDS were determined by physical examination.
In the CTS group, 16/60 hands (26.7%) did not have a PL tendon and 18/60 hands (30%) were lacking fifth FDS function. In the normal group, 27/180 hands (15%) lacked the PL and 25/180 (13.9%) lacked a functional fifth FDS (P = 0.041 and 0.005 for PL and FDS, respectively). Pain distribution and severity of the disease were not related to absence of either of these tendons (P > 0.05).
Our findings showed that the absence of the PL tendon and fifth FDS function, independently and in combination, is more frequent in patients with CTS. Also we found that the severity of CTS or pain distribution in these patients was not related to the presence or absence of these tendons.
本研究旨在探寻掌长肌腱（PL）的存在与小指浅屈肌（FDS）功能及腕管综合征（CTS）之间可能存在的关联。
CTS组和正常组分别包含60只手和180只手。通过详细的病史采集、体格检查及电诊断测试确诊CTS。通过体格检查确定PL肌腱的存在及第五指FDS的功能。
在CTS组中，16/60只手（26.7%）没有PL肌腱，18/60只手（30%）缺乏第五指FDS功能。在正常组中，27/180只手（15%）没有PL肌腱，25/180只手（13.9%）缺乏功能性第五指FDS（PL和FDS的P值分别为0.041和0.005）。疾病的疼痛分布和严重程度与这两种肌腱的缺失均无关（P>0.05）。
我们的研究结果表明，CTS患者中PL肌腱缺失和第五指FDS功能缺失单独或合并出现的情况更为常见。我们还发现，这些患者的CTS严重程度或疼痛分布与这些肌腱的存在与否无关。
