What is the difference between Thoracic outlet syndrome and Carpal tunnel syndrome?
Thoracic outlet syndrome is due to a compression of nerves or arteries at the brachial plexus, and carpal tunnel syndrome is due to nerve compression at the wrist.
What are the primary nerves affected by thoracic outlet syndrome?
The lower two nerves (C8 and T1) are most commonly affected in 90% of persons, following the ulnar nerve distribution.
What are brachial plexus?
The brachial plexus is a network of nerves that originate from the lower cervical and upper thoracic spinal cord. It controls the muscles of the shoulder, arm, and hand, and provides feeling to the upper limb. Damage to the brachial plexus can result in weakness or loss of function in the affected areas.
What nerve are in brachial plexus?
The first thoracic nerve roots are in the brachial plexus. The nerves pass through the neck, the armpit area, and then into the arm.
What is thoracic outlet syndrome?
Thoracic outlet syndrome (TOS) consists of a group of distinct disorders that affect the nerves in the brachial plexus (nerves that pass into the arms from the neck) and various nerves and blood vessels between the base of the neck and axilla (armpit). For the most part, these disorders have very little in common except the site of occurrence. The disorders are complex, somewhat confusing, and poorly defined, each with various signs and symptoms of the upper limb.
The brachial plexus can contain fibers from?
The brachial plexus contains fibers from the ventral rami of the cervical spinal nerves (C5-C8) and the first thoracic spinal nerve (T1). These fibers combine to form the nerves that innervate the upper limb.
What is brachial plexus?
The brachial plexus is a network of nerves that controls movement and sensation in the shoulder, arm, and hand. It is formed by the combination of nerves from the cervical spine and supplies motor and sensory innervation to the upper limb. Damage to the brachial plexus can result in weakness, numbness, or paralysis in the affected arm.
What is the brachial plexus?
The Brachial Plexus is the nerve plexus from which supplies the upper limb. Its root supply is C5 to T1. This means that the nerves which make it up leave the spinal chord at all the vertebrae between the 5th Cervical Vertebrae and the 1st Thoracic Vertebrae. Brachial plexus is a radical regrouping of the nerve fibers that are araising from the vental rami of C7 to C8 and additionally from T1. Through this network of nerves the entire upper limb will get its nerve supply.
What are the causes of thoracic outlet syndrome?
Tinel's test is used to assist in the diagnosis of carpal tunnel syndrome, not thoracic outlet syndrome. It is performed by tapping the median nerve along its course in the wrist. The test is positive when it causes tingling or pain in the thumb, index finger and middle finger.
Which spinal nerves go directly to the tissues they supply rather than forming a plexus?
The thoracic spinal nerves (T1-T12) do not form plexuses like the cervical, brachial, lumbar, and sacral nerves. Instead, each thoracic spinal nerve tends to go directly to the tissues it supplies without forming complex networks.
What are the symptoms and treatment options for brachial plexus compression syndrome?
Brachial plexus compression syndrome can cause symptoms like pain, weakness, and numbness in the arm and hand. Treatment options may include physical therapy, medication, and in severe cases, surgery to relieve the compression on the nerves.
