Thenar eminence pain is a pain in the fleshy area at the base of your thumb. It’s most commonly caused by overuse injuries. Treatment may be splinting or home remedies like ice and heat.
A major factor contributing to this dexterity involves an area known as the thenar eminence, which includes a group of muscles at the base of the thumb. In this article, we will focus on thenar eminence pain, diving deep into its symptoms, causes, diagnosis, and treatment, preventions.
The thenar eminence, a fleshy area at the base of your thumb, can become a source of discomfort and pain. This condition, known as painful thenar eminence , is often caused by a variety of underlying issues that affect the nerves, tendons, and muscles in the wrist and forearm.
Patients typically present with pain, tingling, or paresthesias along the dorsolateral aspect of the wrist, hand, and fingers. Symptoms of pain predominate over other sensory symptoms. Patients may also have the aggravation of their symptoms with motions that involve repetitive wrist flexion and ulnar deviation.
The thenar muscles control adduction, abduction, and opposition of the thumb; other thumb movements are controlled by forearm muscles. The interosseous and lumbrical muscles collectively flex the MCP joints while extending the IP joints, and the interosseous muscles also abduct and adduct the fingers.
Another consequence of the ulnar nerve passing through the hook of the hamate and pisiform bone (the Guyon's canal), compression at this level leads to atrophy, numbness, tingling, and pain in the hypothenar eminence along with fourth and fifth digits. This is much like the 'carpel tunnel syndrome' but in this case the ulnar nerve is involved.
Pain. Most related pain may radiate from the base of the thumb. Deformity. If you notice this around the base of your thumb, it can be due to atrophy of the muscles of the thenar eminence.
Carpal tunnel syndrome is considered a compressive neuropathy of the median nerve that causes pain, paresthesia, and muscle wasting in the thenar eminence. It is diagnosed clinically based on a patient’s signs and symptoms.
What is thenar eminence? Structure and Anatomy with pictures, Function, details about hypothenar muscles, causes of thenar muscle pain, atrophy and treatment.
Carpal tunnel syndrome (CTS) refers to the complex of symptoms and signs brought on by compression of the median nerve as it travels through the carpal tunnel. Patients commonly experience pain and paresthesia, and less commonly weakness, in the median nerve distribution.
