Ulnar Neuropathy: Background, Anatomy, Pathophysiology
Ulnar compression [ tardy ulnar nerve palsy ] in the medial epicondylar region is generally from a valgus deformity of the bone. Campbell used slightly different terminology, lumping the epicondylar groove together with the medial epicondylar region and labeling the entire region the area of the retrocondylar groove.
Traumatic cubitus varus deformity should be recognized as another cause of cubital tunnel syndrome.

Results were excellent in 8 patients, good in 10, and fair in 8; 1 patient had a poor result. Zone 3 encompassing the superficial or sensory branch of the bifurcated nerve – Compression in zone 3 causes sensory loss to the hypothenar eminence, the small finger, and part of the ring finger, but it does not cause motor deficits; tardy ulnar nerve palsy causes are an aneurysm of the ulnar artery, thrombosis, and synovial inflammation.
Anatomy Course of ulnar nerve The ulnar nerve is the terminal branch of the medial cord of the brachial plexus and contains fibers from C8, T1, and, occasionally, C7.

Kaempffe and Farbach reviewed 27 patients who underwent partial medial epicondylectomies and were monitored for an average of 13 months. In two patients, the ulnar nerve was entrapped by scar tissue ulnag the abnormal position and the nerve developed a sharp V-shaped kink when the tardy ulnar nerve palsy was flexed.
