Cubital tunnel syndrome

Tingling in the little and ring fingers can begin at the elbow.

What it is

The ulnar nerve runs along the inner elbow. Compression here can affect hand sensation and strength. The nerve can also be compressed elsewhere.

Symptoms

Little-finger and partial ring-finger numbness may worsen with prolonged elbow bending or pressure. Clumsiness, weakness or muscle wasting may develop in more advanced cases.

Assessment

The elbow, wrist and hand are examined to locate the problem. Nerve conduction studies and ultrasound may clarify nerve function, position and compression.

Non-surgical treatment

Selected cases are managed by reducing pressure and sustained bending, sometimes with night-time protection. Progressive weakness or constant numbness deserves prompt assessment.

When surgery is considered

Surgery may be indicated for neurological deficit or persistent symptoms. Decompression or nerve transposition is chosen according to examination and nerve stability. Risks and possible incomplete recovery are discussed.

Recovery and follow-up

Recovery depends on previous nerve damage and treatment. Long-standing weakness may not fully resolve. Return to pressure, bending and loading is tailored to the procedure.

Frequently asked questions

Is this the carpal tunnel nerve?

No. Carpal tunnel involves the median nerve; this condition involves the ulnar nerve.

Does all little-finger numbness start at the elbow?

No. Other nerve locations and possible causes must be considered.

Why do my ring and little fingers tingle?

This distribution may reflect ulnar nerve involvement. Examination distinguishes elbow, wrist and other causes.

Can sleeping with a bent elbow worsen symptoms?

Sustained flexion can provoke symptoms in some people. Position changes or night protection may help selected cases.

Must the nerve be moved?

Not always. Simple release and transposition have different indications. Nerve stability and examination findings guide the choice.

Will strength fully recover?

This depends on previous damage and duration. Established weakness or wasting may persist; progressive weakness deserves prompt assessment.
