Variations of the abductor pollicis longus tendon: an anatomic study.
This study was performed to investigate the variations, dimensions and attachment of the abductor pollicis longus (APL) tendon. Fifty upper limbs of adult cadavers were dissected in the Faculty of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia. Variations of APL tendon and its way of insertion were observed;its length, width and thickness were also measured and statistically analysed...
متن کاملA rare origin of abductor pollicis longus.
Abductor pollicis longus is known for its variations in the form of multiple tendons at its insertion. The present case reports about a variation in the origin of abductor pollicis longus (APL) which has not been cited in the medical literature until date. It has been shown that the intersection area where the APL and extensor pollicis brevis cross over the tendons of the extensor carpi radiali...
متن کاملMultiple tendons of abductor pollicis longus
The extensor compartment of the forearm of the human body is one with frequent variations of its contents. Among all, the abductor pollicis longus (APL) muscle is known to exhibit numerous variations. Variations in the number of tendons of APL muscle may be asymptomatic and often incidental finding [1]. The present variation detected in a 63-year-old male cadaver, describes the APL muscle havin...
متن کاملFunctional relationship between the abductor pollicis longus and abductor pollicis brevis muscles: an EMG analysis.
This study examined the anatomical and functional relationships between the abductor pollicis longus (APL) and the abductor pollicis brevis (APB) muscles. The APL has 2 divisions, a distal superficial division and a more proximal deep one. A direct anatomical connection between the extrinsic and intrinsic muscles of the thumb is made up by the deep division of the APL, the APB and the trapezium...
متن کاملA Rare Quadruplicate Arrangement of Abductor Pollicis Longus Tendons - Anatomical and Clinical Relevance
Movements of the thumb are carried out by extrinsic and intrinsic muscles and have immense phylogenetic and evolutionary significance. The number, length, and thickness of APL accessory tendons may have a functional role in the etiology of DeQuervain’s stenosing tenovaginitis. Thus, precise knowledge of the variations in this region is important for hand surgeons. Additionally, these tendons ma...
