Early in the disorder, primary complaint is typically medial elbow pain. Numbness and tingling may also be present in the 4th and 5th digits. The patient may also report non-painful "snapping" or "popping" during active and passive flexion and extension of the elbow.

Clinically Relevant Anatomy
[edit | edit source]
Cubital tunnel syndrome is an irritation or injury of the ulnar nerve in the cubital tunnel at the elbow. The ulnar nerve is comprised of nerve roots C8 and T1. The ulnar nerve can become compressed withiin the cubital tunnel at multiple levels including: the arcade of Struthers, the medial intermuscular septum, the medial epicondyle, Osborn's ligament at the cubital tunnel and the flexor-pronator aponeurosis.[1]
Mechanism of Injury / Pathological Process
[edit | edit source]
Cubital tunnel syndrome may be a result of direct or indirect trauma and is bulnerable to traction, friction, and compression. Traction injuries may be the result of longstanding valgus deformity and flexion contractures, but are most common in throwers due to extreme valgus stress placed on the arm. [2] Compression of the nerve at the cubital tunnel may occur due to reactive changes at the MCL, adhesions within the tunnel, hypertrophy of the surrounding musculature, or joint changes.[3]
Clinical Presentation[edit | edit source]
Early in the disorder, primary complaint is typically medial elbow pain. Numbness and tingling may also be present in the 4th and 5th digits. The patient may also report non-painful "snapping" or "popping" during active and passive flexion and extension of the elbow. A Wartenberg sign (abduction of the fifth digit due to weakness of the third palmar interosseous muscle) may be present. Active and passive ROM may not be decreased.
