Ulnar neuropathy can progress to weakness and atrophy of the muscles in the hand (interossei and small and ring finger lumbricals).

The hallmark symptoms of ulnar neuropathy at the elbow (cubital tunnel syndrome) is paresthesia (tingling).

In cubital tunnel syndrome (ulnar neuropathy at the elbow), sensory and motor symptoms tend to occur in a certain sequence.

Initially, there may be intermittent paresthesia and loss of sensibility of the small and ulnar half of the ring fingers.

Variations in anatomy such as the anconeus epitrochlearis muscle are common and their relationship to ulnar neuropathy is uncertain.

[5] Compression of the ulnar nerve at the medial elbow may occur with an epitrocheloanconeus muscle, an anatomical variant.

[12] For pain symptoms, medications such as NSAID, amitriptyline, or vitamin B6 supplementation may help although there is no evidence to support this claim.

The ulnar nerve is identified and released from its fascia proximally and distally up to the flexor carpi ulnaris heads.

[4] People with diabetes mellitus are at higher risk for any kind of peripheral neuropathy, including ulnar nerve entrapments.

[4] Cubital tunnel syndrome is more common in people who spend long periods of time with their elbows bent, such as when holding a telephone to the head.

[4] Flexing the elbow while the arm is pressed against a hard surface, such as leaning against the edge of a table, is a significant risk factor.

[4] There is some evidence that soft tissue compression of the nerve pathway in the shoulder by a bra strap over many years can cause symptoms of ulnar neuropathy, especially in very large-breasted women.
