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 کاملAbductor pollicis longus tendon division with swan neck thumb deformity
Swan neck thumb deformity can be caused by osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, tendon transfers and paralytic diseases. Abductor pollicis longus is one of the major stabilizing tendon of the carpometacarpal joint of thumb. To the best of our knowledge, swan neck thumb deformity owing to division of abductor pollicis longus tendon is rare. In this article, we desc...
متن کاملExtensor indicis proprius tendon transfer for extensor pollicis longus rupture
The extensor pollicis longus (EPL) tendon is one of the most frequently ruptured tendons. The EPL is the primary extensor of the interphalangeal (IP) joint of the thumb and is also important in metacarpophalangeal (MCP) joint extension. The loss of this tendon leads to an inability to extend the thumb and raise it to the level of the palm, leaving the patient with a useless thumb (1). Clinicall...
متن کاملRupture of the extensor pollicis longus tendon after Colles fracture.
During the period 1973-1986, 116 patients with rupture of the extensor pollicis longus tendon were operated upon. The lesions were categorised into three anatomical levels: proximal, intermediate and distal. Direct suture was performed for acute lesions; later reconstructive procedures were by means of tendon transfers or free tendon grafts.
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...
