The muscle originates from the lateral tibia and interosseous membrane, inserting on the base of the first metatarsal and medial first cuneiform. Occasionally, the distal tendon may insert only on the cuneiform.1. (A) A 2.7-mm Wissinger rod (WR) is inserted into the FPL tendon sheath via the phalangeal portal (PP).

Since it lies in the forearm but inserts in the hand, flexor pollicis longus is also classified as an extrinsic muscle of the hand. Gerrish's Text-book of Anatomy (1902) - Fig. In other primates there is only one common deep flexor that provides a tendon to the thumb. Because it is one of the causes of anterior interosseous nerve syndrome (AINS), a study was carried out on 120 Thai cadavers (70 embalmed, 50 fresh; 78 male, 42 female) to elucidate the prevalence of AHFPL, its morphology and relationship with the anterior … 10.1055/b-0040-177427 12 Superficialis Transfer for Rupture of the Flexor Pollicis Longus TendonAlexandria L.

The following 3 files are in this category, out of 3 total. It lies in the same plane as the flexor digitorum profundus. Flexor muscles are muscles that decrease the angle while extensor muscles are muscles that increase the angle. An example of flexor muscles are the biceps brachii and hamstrings. an example of extensor muscles are the triceps brachii, quadriceps femoris, and the gastrocnemius A detailed description of the accessory head of flexor pollicis longus muscle (AHFPL) in the Thai population has not been reported. 21224; slifche1@jhmi.edu.

Abstract Background: The aim of flexor pollicis longus (FPL) repair is to create a construct that is strong enough to withstand forces encountered during rehabilitation and to achieve an optimal active range of motion. Insertion: Base of distal phalanx of thumb. Introduction. The Flexor Pollicis Longus muscle forms a part of the lower half of the arm which means it is located from the elbow moving downwards. Media in category "Flexor pollicis longus muscles". Origin: Posterior surfaces of ulna, radius and interosseous membrane. State the origins of flexor digitorum superficialis. Muscles are classified according to their actions during contractions as agonists, antagonists, or synergists. For muscle pairings referred to as antagonistic pairs, one muscle is designated as the extensor muscle, which contracts to open the joint, and the flexor muscle, which acts opposite to the extensor muscle . originates from the back of the fibula (outer lower leg bone), it then travels down along the inside of the lower leg and ankle where it inserts into the base of the big toe via the flexor Flexor digitorum profundus. The flexor digitorum profundus helps flex the fingers. The muscle originates in the upper part of the ulna bone. It inserts at the distal phalanges in the tips of the fingers. 1 Definition.

The function of this muscle is to facilitate thumb flexion. Rupture of the tendon of flexor pollicis longus is suspected when active flexion of the interphalangeal joint of the thumb is not possible. It belongs to the deep flexors of the forearm, along with flexor digitorum profundus and pronator quadratus. There is edema and hemorrhage along the discontinuity. Modern humans possess a distinct and well-developed flexor pollicis longus muscle, an extrinsic thumb flexor which is “either rudimentary or absent” in great apes (Straus, 1942, p. 228). Author Information. Flexor digitorum superficialis. There is discontinuity of the flexor pollicis longus tendon with 25 mm gap, extending from the carpal tunnel to the level of the first metacarpal bone mid diaphysis. Like many muscles of the lower arm, and as its name suggests, the flexor pollicis longus is a long muscle that originates from the radius and inserts into the thumb. In some cases, this condition is exactly duplicated in humans; in other cases, the muscle has been found fused with the index tendon of flexor digitorum profundus (as in the gorilla and chimpanzee). Hand. Vaše hodnocení ovšem nebylo vloženo (článek je možné hodnotit jen jednou za den)! a powerful muscle located on the posterior aspect of the fibular below the deep fascia of the calf. doi: 10.1007/s11552-007-9045-3.
