The hallmark symptoms of ulnar neuropathy at the elbow is paresthesia (tingling). This can progress to a loss of sensibility. Muscle weakness is usually experienced as a loss of dexterity.
[[Ulnar neuropathy]] at the wrist ([[ulnar tunnel syndrome]]) is associated with variable symptoms, as the ulnar nerve separates near the hand into distinct motor and sensory branches.
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. Next is constant numbness (loss of sensibility). The final stage is intrinsic hand muscle atrophy and weakness.
In contrast, when ulnar neuropathy occurs at the wrist (
