Evidence Checklist: Cubital Tunnel Syndrome (Ulnar Nerve Entrapment at Elbow)

Neurological evaluation documenting ulnar nerve symptomsCritical

Examination by a neurologist or hand specialist documenting numbness, tingling, and weakness in the ring and little fingers, grip weakness, and positive Tinel sign at the elbow.

EMG/nerve conduction study confirming ulnar neuropathy at elbowCritical

Objective electrodiagnostic testing isolating ulnar nerve entrapment at the elbow, documenting severity (mild, moderate, or severe).

Nexus opinion linking cubital tunnel syndrome to serviceCritical

A medical opinion stating it is "at least as likely as not" that your ulnar neuropathy is connected to military service, repetitive duties, or a service-connected injury.

Documentation of dominant vs. non-dominant hand

Medical records noting which hand is dominant — the dominant extremity receives a higher rating under the peripheral nerves schedule.

Imaging studies if structural cause suspected (MRI or ultrasound of elbow)

Imaging to identify bone spurs, cysts, or other structural causes of ulnar nerve compression at the cubital tunnel.

Treatment records (splinting, physical therapy, surgery)

Records showing conservative treatment attempts (night splinting, NSAIDs, activity modification) and any surgical intervention (ulnar nerve transposition or decompression).

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Completed DBQ Peripheral Nerves ConditionsCritical

Standardized form capturing ulnar nerve involvement severity, sensory and motor deficits, and functional impact.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
