What is an EPL rupture?
Spontaneous rupture of the extensor pollicis longus (EPL) tendon at the wrist is uncommon and mainly reported after fracture of the distal radius at Lister’s tubercle, in synovitis, tenosynovitis, or rheumatoid arthritis [1].
What is the EPL tendon?
What is the EPL tendon? The long extensor tendon to the thumb is called the Extensor Pollicis Longus (EPL). This tendon straightens the end joint of the thumb (thumbs up or hitch hikers sign – see Figure 1) and also helps pull the thumb in towards the index finger.
Where is the EPL tendon?
Extensor pollicis longus (EPL) is a long muscle located at the deep layer with extensor pollicis brevis, abductor pollicis longus, extensor indicis, and supinator muscle in the posterior compartment of the forearm.
What is EPL in anatomy?
Extensor pollicis longus (EPL) muscle is a muscle of the deep compartment in the posterior compartment of the forearm. It passes through the 3rd extensor compartment of the wrist, then continues laterally towards the thumb around Lister’s tubercle. The tendon of EPL defines the ulnar border of the anatomical snuffbox.
What is the function of EPL?
The function of EPL is to extend the IP joint and to stabilize the metacarpophalangeal (MP) joint extension of the thumb in the plane of the hand. Perhaps its major functional role is to allow the first metacarpal to rise dorsally and medially toward the index finger to facilitate pinch.
What does EPL stand for in medicine?
Extensor Pollicis Longus Medical Definition | Merriam-Webster Medical Dictionary.
How is EPL function tested?
The EPL can be tested by placing the patient’s hand flat on a table and asking the patient to lift the thumb toward the second metacarpal; the EPL can be palpated toward the ulnar side of the snuffbox if it is present.
How do you assess EPL?
What is the medical definition of tenorrhaphy?
Medical Definition of tenorrhaphy. : surgical suture of a divided tendon.
How is tenorrhaphy used to treat avulsion injuries?
three-loop tenorrhaphy. a technique used for the repair of avulsion injuries of tendons, particularly the gastrocnemius tendon. It involves multiple throws of suture material through the tendon and the site of attachment. Its advantages are better closure of gaps with minimal distortion of tendon ends and disruption of blood flow.
What is the shape of the EPL tendon?
EPL tendinosis and irregular tubercle. 7 a-b: Axial proton density-weighted images near the level of Lister’s tubercle demonstrate an irregular pedunculated appearance of the tubercle with notching of the adjacent cortical bone (white arrows). The EPL tendon is abnormally thickened with intermediate signal, consistent with tendinosis.
What kind of graft is used for EPL rupture?
EPL repair using palmaris longus graft. 9a-b: Intraoperative photos of our initial unknown case (figures 1-2) confirm complete rupture of the EPL tendon near Lister’s tubercle. The preoperative MRI was used to plan precise small incisions and retrieve the proximal and distal torn tendon stumps (held by forceps).
