Ulnar neuropathy is a disorder involving the ulnar nerve. Ulnar neuropathy may be caused by entrapment of the ulnar nerve with resultant numbness and tingling. [3] It may also cause weakness or paralysis of the muscles supplied by the nerve. Ulnar neuropathy may affect the elbow as cubital tunnel syndrome.
The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11] The procedure is performed on an outpatient basis allowing discharge the same day, with the arm in a splint to protect the repair for the first week. [10]
An anastomosis occurs when two structures that normally are not connected have a connection. In this case the connection is a nerve. The Martin-Gruber anastomosis is most common anastomosis that occurs between these two nerves. [1] This connection carries motor axons which innervate some of the usually ulnar nerve innervated intrinsic muscles.
The latter involves compression at the wrist of the superficial sensory branch of the radial nerve which does not innervate hand muscles. [ citation needed ] Robert Wartenberg (1887-1956) was a neurologist born in Belarus who worked in Germany until 1935 when he emigrated to the United States.
One patient developed postoperative ulnar nerve damage. Two patients had damage to the posteromedial part of the olecranon and required reoperation. [25] A 2015 study found that MLB pitchers who had Tommy John surgery returned to pitch in the MLB 83% of the time and only 3% failed to return to pitch in the MLB or the minor leagues. [21]
Cubital tunnel syndrome is an entrapment neuropathy, or nerve compression syndrome, a condition caused by compression, traction or friction, of the ulnar nerve at the elbow. [1] Nerve compression is also known as a trapped nerve. The ulnar nerve travels from the shoulder (brachial plexus) down the length of the arm to the hand.
Ulnar tunnel syndrome, also known as Guyon's canal syndrome or Handlebar palsy, is ulnar neuropathy at the wrist where it passes through the ulnar tunnel (Guyon's canal). [1] The most common presentation is a palsy of the deep motor branch of the ulnar nerve causing weakness of the interosseous muscles .
The symptoms of nerve injury in the early 1900s were called nerve palsy (today neuropathy or neuritis are more common terms). [50] The concept of injuries causing nerve palsy was understood at that time. [49] For example, wrist fractures were known to be a cause of nerve palsy through compression, and this could be treated by liberating the nerve.
