LONG ABDUCTEUR POUCE [7 records]

Record 1 2013-11-15

English

Subject field(s)
  • Symptoms (Medicine)
  • Nervous System
  • Bones and Joints
DEF

A condition in which the hand is flexed at the wrist and cannot be extended due to paralysis of the extensor muscles of the hand and fingers.

CONT

In the wrist-drop of a high radial nerve palsy not only are the wrist extensors out, but also ... [the] extensors of the fingers and thumb and the long abductor of the thumb.

OBS

wristdrop: term recommended by the Medical Signs and Symptoms Committee.

Domaine(s)
  • Symptômes (Médecine)
  • Système nerveux
  • Os et articulations
DEF

Main tombante par paralysie des muscles extenseurs et ayant une position, par rapport à l’avant-bras, qui rappelle un col de cygne.

CONT

La main tombante [...] est causée par la paralysie du nerf radial. La paralysie du muscle extenseur carpicubital et des radiaux entraîne une chute du poignet; celle de l'extenseur commun des doigts, de l'extenseur propre de l'index et du 5e doigt entraîne une impossibilité d’étendre les articulations métacarpophalangiennes; celle des extenseurs et du long abducteur du pouce maintient le pouce en flexion et adduction.

Record 2 2012-02-24

English

Subject field(s)
  • Muscles and Tendons
DEF

Inflammation of the tendons and sheath of abductor pollicis longus and extensor pollicis brevis, in the first dorsal compartment of the wrist, with subsequent thickening and stenosis.

French

Domaine(s)
  • Muscles et tendons
DEF

Épaississement fibreux circulaire de la gaine des tendons long abducteur et court extenseur du pouce, avec une tuméfaction et des douleurs exacerbées lors des mouvements.

Record 3 2010-07-22

English

Subject field(s)
  • Radiography (Medicine)
  • Musculoskeletal System
DEF

Intraarticular avulsion fracture subluxation of the base of the first metacarpal. The fracture produces a small volar lip fragment that remains attached to the trapezium and trapezoid by means of the strong volar oblique ligament while the shaft fragment is displaced by proximal muscle pull.

French

Domaine(s)
  • Radiographie (Médecine)
  • Appareil locomoteur (Médecine)
DEF

Fracture intra-articulaire de la base du premier métacarpien, détachant un fragment palmaire qui garde ses connexions avec le trapèze par le puissant ligament postéro-interne, alors que l'os se subluxe en haut et en dehors sous l'action du muscle long abducteur du pouce.

Record 4 2005-06-10

English

Subject field(s)
  • Human Diseases - Various
  • Muscles and Tendons
DEF

A specific type of tenosynovitis which involves the tendons of two specific muscles on the thumb side of the hand - the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These muscles are located in the forearm and their tendons travel across the wrist (through a "tunnel" termed the first dorsal compartment) on the thumb side to produce movement of the thumb. The walls of the affected tendon sheaths (basically protective coverings for the tendons) become thickened and inflamed.

OBS

The precise cause of de Quervain's tenosynovitis is unknown. It is thought that excessive friction from overuse of the thumb and wrist (excessive and repetitive gripping and grasping actions) may be a factor, leading to thickening of the tissues in the compartment housing the APL and EPB tendons. For example, cases have been described in bricklayers, those who sew, piano players, fly fishermen, and golfers. It has also been hypothesized that the condition in some cases may be associated with acute injury to the involved area (direct blow to the forearm or wrist, falling on the thumb).

OBS

blackberry thumb: Experts caution that practical experience and emerging anecdotal evidence suggest overuse of personal digital assistants (PDAs) ... can conceivably lead to injury of the tendons and accompanying tissue of the thumb. "Blackberry thumb" is the latest colloquial interpretation of a very real medical condition called de Quervain's tendonitis, and its variant de Quervain's tenosynovitis. The names refer to inflammation of two tendons that control the opposable digit, or their protective tissue.

Key term(s)

French

Domaine(s)
  • Maladies humaines diverses
  • Muscles et tendons
DEF

Inflammation de la gaine entourant les tendons du long abducteur et du court extenseur du pouce(ténosynovite) qui cheminent tous deux dans le même tunnel fibreux, au bord externe du poignet, au contact du radius.

Record 5 2005-06-09

English

Subject field(s)
  • Human Diseases - Various
  • Muscles and Tendons
DEF

A condition brought on by irritation or swelling of the tendons found along the thumb side of the wrist. The irritation causes the compartment (lining) around the tendon to swell, changing the shape of the compartment; this makes it difficult for the tendons to move as they should. The swelling can cause pain and tenderness along the thumb side of the wrist, usually noticed when forming a fist, grasping or gripping things, or turning the wrist.

French

Domaine(s)
  • Maladies humaines diverses
  • Muscles et tendons
DEF

Inflammation des tendons du pouce près de l’articulation du poignet.

CONT

La tendinite de de Quervain touche les tendons du long abducteur et du court extenseur du pouce.

OBS

C’est le frottement et les micros traumatismes répétés au niveau de ces tendons contenus dans une gaine étroite qui créent une inflammation tendineuse. L’irritation débute souvent à l’occasion d’un changement d’activité ou d’un choc. Elle s’entretient ensuite d’elle même par les frottements des tendons qui augmentent de volume dans une gaine qui elle est rigide et inextensible.

Record 6 1995-12-07

English

Subject field(s)
  • Musculoskeletal System
CONT

Complications consisted of a 0,74 per cent infection rate (osteitis), 2.2 per cent non-union, 1.5 per cent with a synostosis, 0 per cent refracture and 2.2 per cent migration of nails, combined with tendon rupture.

French

Domaine(s)
  • Appareil locomoteur (Médecine)
CONT

Une migration des broches [embrochage multifasciculé] a été observée 3 fois, en rapport avec le non-respect des règles de l'embrochage décrites par Hackethal. Ces migrations des broches ont été responsables de trois ruptures tendineuses, dont deux au niveau de l'extenseur long du pouce, et une au niveau du long abducteur du pouce.

La ténosynovite sténosante de De Quervain.(...) elle est la conséquence d’une sténose progressive de la gaine des tendons du long abducteur et du court extenseur du pouce, dans la première coulisse ostéofibreuse dorsale située au niveau de l'apophyse styloide radiale. Le rétrécissement de la lumière de ce tunnel étrangle les tendons(...)
