Answer

No gross anatomic differences in the course of the nerve are noted between the sexes. However, the following have been noted [77] :

  • Men develop perioperative ulnar neuropathies [28] at the elbow [78] more frequently than women do [76] ; cubital tunnel syndrome is 3-8 times more common in men

  • Women have 2-19 times more fat content in the medial elbow overlying the tubercle of the ulnar coronoid process

  • The tubercle of the coronoid process is 1.5 times larger in men

Contreras et al suggested that the coronoid process may be a potential site for ulnar nerve compression in men and that the increased subcutaneous fat around the ulnar nerve in women may provide a protective advantage against acute ulnar neuropathy. [77]
