一个形态学研究斜韧带在拇指提出。该韧带在人类标本中得到了一致的描述，并与来自不同物种的非人类灵长类动物的解剖进行了比较。斜韧带在一些（但不是全部）被检查过的物种标本中被发现：黑猩猩、猩猩、长臂猿、无尾狒狒、hamadryas狒狒、松鼠猴、狐猴和狨猴。斜韧带的修订身份被提出作为纤维-骨环形政治屈肌鞘的加强远端边界，其功能不独立于屈肌鞘。与非人类灵长类动物相比，人类政治斜韧带的持续存在和肌腱特征支持了斜韧带加强人类政治屈肌鞘的观点，以便在用力精确捏捏时约束拇长屈肌肌腱。政治斜韧带的一个衍生被认为代表了拇指拇浅屈肌腱的残余桡肢。
A morphological study of the oblique ligament in the thumb is presented. The ligament was consistently described in human specimens and compared with dissections of non‐human primates from different species. The oblique ligament was found in some, but not all, specimens in each of the following species examined: chimpanzee, orang‐utan, gibbon, anubis baboon, hamadryas baboon, squirrel monkey, lemur and marmoset. A revised identity of the oblique ligament is proposed as a reinforced distal border of a fibro‐osseous annular pollical flexor sheath and whose function is not independent of the flexor sheath. The constant presence and tendinous trait of the pollical oblique ligament in humans, when compared with non‐human primates, supports the notion that the oblique ligament strengthens the pollical flexor sheath in humans for restraint of the flexor pollicis longus tendon during forceful precision pinching. A derivation of the pollical oblique ligament is considered as representing a vestigial radial limb of a flexor pollicis superficialis tendon in the thumb.
