Eighty-two wrists of Thai cadavers and the wrists of 66 patients with de Quervain syndrome were studied, and the variation in the number of tendons and the fibro-osseous tunnel in the first extensor compartment were recorded. The abductor pollicis longus had more than one tendon in 73 of the cadavers (89%) and in 32 of the patients (49%) (p <0.001). The extensor pollicis brevis was a single tendon in 80 (98%) and 62 (94%) of cadavers and patients, respectively. There was division with the septum that made a fibro-osseous tunnel in the first extensor compartment in 30/82 (37%) cadavers and in 38/66 (58%) patients with de Quervain syndrome (p = 0.01). The results indicate that the number of fibro-osseous tunnels and multiple compartments in the first extensor compartment may be associated with a predisposition to de Quervain syndrome.
对82例泰国尸体的手腕以及66例患有桡骨茎突狭窄性腱鞘炎患者的手腕进行了研究,并记录了第一伸肌间隔内肌腱数量和纤维骨性隧道的变异情况。73例(89%)尸体和32例(49%)患者的拇长展肌有不止一条肌腱(p<0.001)。拇短伸肌在80例(98%)尸体和62例(94%)患者中均为单条肌腱。在30/82(37%)例尸体和38/66(58%)例桡骨茎突狭窄性腱鞘炎患者中,第一伸肌间隔内存在由隔膜分隔形成的纤维骨性隧道(p = 0.01)。结果表明,第一伸肌间隔内纤维骨性隧道的数量和多个间隔可能与桡骨茎突狭窄性腱鞘炎的易患性有关。
