What does the abductor pollicis longus muscle do?
The Abductor pollicis longus (APL) is one of a deep extensor of the forearm and is responsible for facilitating movement and stabilization of the thumb. Its tendon is present in the first extensor compartment of the wrist. It lies immediately below the supinator and sometimes unites with it.
Why does my adductor Pollicis hurt?
Pain in the adductor pollicis can occur due to osteoarthritis, soft-tissue trauma in the hand or excessive strain. One condition which can affect the adductor pollicis and thumb adduction is the gamekeeper’s thumb, in which the ulnar collateral ligament above the adductor pollicis is overly strained.
What does longus mean in anatomy?
: a long structure (as a muscle) in the body — see abductor pollicis longus, adductor longus, extensor carpi radialis longus, extensor digitorum longus, extensor hallucis longus, extensor pollicis longus, flexor digitorum longus, flexor hallucis longus, flexor pollicis longus, palmaris longus, peroneus longus.
How do you relieve abductor pollicis brevis pain?
This causes the abductor pollicis longus and surrounding muscles and tendons to become inflamed, leading to pain. Treatment methods for pain can include applying ice, immobilisation of the thumb and wrist and anti-inflammatory medications.
What is the abductor digiti minimi muscle?
The abductor digiti minimi (ADM) muscle generally arises from the pisiform bone, flexor carpi ulnaris (FCU) tendon and pisohammate ligament.
What is abductor pollicis longus?
Abductor pollicis longus is a muscle found in the posterior compartment of the forearm. It is one of the five deep extensors in the forearm, along with the supinator, extensor pollicis brevis, extensor pollicis longus and extensor indicis.
Is the accessory abductor digiti minimi a cause of entrapment neuropathy?
Biaponeurotic palmaris longus and accessory abductor digiti minimi are important structural causes of the entrapment neuropathies of forearm and wrist. Diagnosis of these muscles as a cause of entrapment neuropathies requires the sound knowledge of variant muscles in the forearm and wrist region.
What nerve innervates the abductor digiti minimi?
Like other hypothenar muscles, abductor digiti minimi receives nervous supply from the deep branch of the ulnar nerve, derived from root values C8 and T1. Abductor digiti minimi receives arterial blood supply from the palmar branch of ulnar artery, palmar digital artery, as well as branches of the ulnar side of the superficial palmar arch.
