[7] After traveling through the supinator muscle (approximately 4 cm) (Figure 43.11), the posterior interosseous nerve divides and gives off typically six branches to the extensor carpi ulnaris, extensor digiti minimi, extensor digitorum communis, extensor pollicis brevis and longus, abductor pollicis longus, and extensor indicis muscles.

It The extensor pollicis brevis has a similar, although reduced, function. It mainly extends the thumb at the joint where it joins the palm. In direct contrast to the extensor pollicis longus, the additional function of the extensor pollicis brevis is to abduct the first metacarpal. The abductor pollicis longus muscle is innervated by the posterior interosseous nerve, which is a continuation of the deep branch of the radial nerve after it passes through the supinator muscle.

Clinical Importance :- De Quervain disease : Tenosynovitis of the sheath or tunnel that surrounds two tendons that control movement of the thumb. During an investigation performed on cadaver forearms in the anatomy department, an unusual insertion of the abductor pollicis longus (APL) muscle together with the extensor pollicis brevis (EPB) muscle was encountered unilaterally in a 40-year-old male cadaver forearm. APL originated from the posterior ulnar surface distal to the anconeus, the adjoining interosseous membrane and middle third 2020-07-22 · De Quervain’s Syndrome is the layman’s name for “tenosynovitis of the extensor pollicis brevis (EPB) and the abductor pollicis longus (APL) tendons”. I’m sure that cleared things up, right?

The abductor pollicis longus muscle is innervated by the posterior interosseous nerve, which is a continuation of the deep branch of the radial nerve after it passes through the supinator muscle. Abductor pollicis longus lies close to the radial nerve. The posterior interosseous nerve is derived from spinal segments C7 & C8. Blood supply

7 Summary of study features included in this review Extensor Pollicis Longus Tendon Repair !erapy Instructions Laith Al-Shihabi, MD 2-4 weeks Splint: -Fashion a removable short-arm thumb spica splint holding the wrist in 30 degrees of extension, thumb CMC joint in full radial abduction and extension, MCP joint in neutral, and IP joint in neutral to slight hyperextension. Motion: 1982-10-01 A 73-year-old female suffered spontaneous rupture of the extensor pollicis longus (EPL) and extensor pollicis brevis (EPB) tendons, for which she presented for treatment three to four weeks later. At that time there was no active metacarpophalangeal (MCP) or interphalangeal (IP) extension, leading to severe functional impairment of her hand. Abductor Pollicis Longus: The abductor pollicis longus muscle is situated immediately distal to the supinator muscle.
