Summary of "Tardy Ulnar Nerve Palsy."

Tardy ulnar nerve palsy is a chronic clinical condition characterized by a delayed onset ulnar neuropathy after an injury to the elbow. Typically, tardy ulnar nerve palsy occurs as a consequence of nonunion of pediatric lateral condyle fractures at the elbow, which eventually lead to a cubitus valgus deformity. While the child grows, the deformity worsens and the ulnar nerve is gradually stretched until classic symptoms of ulnar nerve neuropathy appear. Other childhood elbow trauma has also been associated with tardy ulnar nerve palsy, including supracondylar fractures resulting in cubitus varus, fractures of the medial condyle and of the olecranon, as well as radial head or Monteggia fractures/dislocation, with or without deformity. The clinical assessment includes obtaining a complete history, physical examination, nerve conduction tests, and elbow imaging studies. Treatment consists of ulnar nerve decompression, with or without corrective osteotomy, with overall successful results usually achieved.

Missed proximal radioulnar joint translocation with ulnar nerve entrapment: an unusual injury in a child.

Traumatic elbow dislocation in a child is rare, and it is usually associated with fractures. Simultaneous proximal radioulnar joint (PRUJ) translocation with ulnar nerve palsy is even rarer. We report...

Imaging appearance following surgical decompression of the ulnar nerve.

Ulnar neuropathy at the elbow is the second most common entrapment neuropathy of the upper extremity. Yet, there is a paucity of literature focusing on the imaging appearance following surgical decomp...

Medical and Biotech [MESH] Definitions

A major nerve of the upper extremity. In humans, the fibers of the ulnar nerve originate in the lower cervical and upper thoracic spinal cord (usually C7 to T1), travel via the medial cord of the brachial plexus, and supply sensory and motor innervation to parts of the hand and forearm.

Ulnar neuropathies caused by mechanical compression of the nerve at any location from its origin at the BRACHIAL PLEXUS to its terminations in the hand. Common sites of compression include the retroepicondylar groove, cubital tunnel at the elbow (CUBITAL TUNNEL SYNDROME), and Guyon's canal at the wrist. Clinical features depend on the site of injury, but may include weakness or paralysis of wrist flexion, finger flexion, and ulnar innervated intrinsic hand muscles, and impaired sensation over the ulnar aspect of the hand, fifth finger, and ulnar half of the ring finger. (Joynt, Clinical Neurology, 1995, Ch51, p43)

Compression of the ULNAR NERVE in the cubital tunnel, which is formed by the two heads of the flexor carpi ulnaris muscle, humeral-ulnar aponeurosis, and medial ligaments of the elbow. This condition may follow trauma or occur in association with processes which produce nerve enlargement or narrowing of the canal. Manifestations include elbow pain and PARESTHESIA radiating distally, weakness of ulnar innervated intrinsic hand muscles, and loss of sensation over the hypothenar region, fifth finger, and ulnar aspect of the ring finger. (Joynt, Clinical Neurology, 1995, Ch51, p43)

Childhood-onset of recurrent headaches with an oculomotor cranial nerve palsy. Typically, ABDUCENS NERVE; OCULOMOTOR NERVE; and TROCHLEAR NERVE are involved with DIPLOPIA and BLEPHAROPTOSIS.

Disease involving the ULNAR NERVE from its origin in the BRACHIAL PLEXUS to its termination in the hand. Clinical manifestations may include PARESIS or PARALYSIS of wrist flexion, finger flexion, thumb adduction, finger abduction, and finger adduction. Sensation over the medial palm, fifth finger, and ulnar aspect of the ring finger may also be impaired. Common sites of injury include the AXILLA, cubital tunnel at the ELBOW, and Guyon's canal at the wrist. (From Joynt, Clinical Neurology, 1995, Ch51 pp43-5)
