The aim of this study was to determine whether there is an association between flexor digitorum and lumbrical muscle intrusion into the carpal tunnel and carpal tunnel syndrome (CTS).
Five hundred thirteen manual laborers (1026 wrists) were evaluated with ultrasound to determine whether those with CTS had more muscle intrusion into the carpal tunnel than those without CTS. One hundred ninety of the participants without CTS at baseline (363 wrists) were followed over 1 year to determine whether muscle intrusion at baseline predicted the development of CTS.
Participants with CTS had more muscle within the carpal tunnel with the wrist in the neutral (P=0.026) and flexed (P=0.018) positions than those without CTS. Baseline muscle intrusion did not predict development of CTS at 1 year.
Muscle intrusion into the carpal tunnel is associated with CTS, but muscle intrusion alone does not predict the development of CTS over the course of a year.
本研究的目的是确定指屈肌和蚓状肌侵入腕管与腕管综合征（CTS）之间是否存在关联。
对513名体力劳动者（1026只手腕）进行超声评估，以确定患有CTS的人是否比未患CTS的人有更多的肌肉侵入腕管。对190名基线时无CTS的参与者（363只手腕）进行了为期1年的随访，以确定基线时的肌肉侵入情况是否可预测CTS的发生。
与未患CTS的人相比，患CTS的参与者在手腕处于中立位（P = 0.026）和屈曲位（P = 0.018）时，腕管内的肌肉更多。基线时的肌肉侵入情况并不能预测1年后CTS的发生。
肌肉侵入腕管与CTS有关，但仅肌肉侵入并不能预测一年内CTS的发生。
