Cubital Tunnel Surgery
in Rockhampton

What is going on

Cubital tunnel syndrome is compression of the ulnar nerve as it passes behind the medial epicondyle of the elbow — the funny-bone region. Patients describe pins-and-needles or numbness in the little and ring fingers, often worse with the elbow bent (driving, holding a phone, sleeping with the elbow flexed). More advanced cases bring weakness of pinch and grip, loss of dexterity (clumsiness with fine tasks like buttoning a shirt or handling coins), clawing of the ring and little fingers in long-standing compression, and visible wasting between the thumb and index finger as the small hand muscles supplied by the ulnar nerve atrophy. The condition is the second-most-common compression neuropathy of the upper limb after carpal tunnel; it can develop with no obvious trigger or follow elbow trauma, prolonged elbow flexion, or work activity.

Not sure if this is the right diagnosis? The elbow pain hub triages the differential by anatomical location.

What the operation involves

The standard operation is **in-situ cubital tunnel release** — a 5–8 cm incision behind the medial epicondyle, dividing the fascial roof of the cubital tunnel and releasing the nerve along its course. The nerve is left in its normal anatomical bed unless it subluxes anteriorly with elbow flexion, in which case anterior subcutaneous transposition is performed. The procedure is typically done under regional or general anaesthesia as a day case, takes around 30 to 45 minutes, and is closed with absorbable sutures and a soft dressing. Full clinical detail is on the education page, and the cubital tunnel syndrome education page covers the underlying condition.

For full clinical detail — incision, anaesthetic, post-operative instructions and the printable patient handout — see the cubital tunnel release education page or the elbow surgery overview.

How this case is handled

The practice's first consult typically focuses on confirming the diagnosis — examination, pattern of symptoms, and review of nerve-conduction studies — and ruling out other causes of medial elbow or hand symptoms (cervical radiculopathy, double-crush at wrist and elbow, thoracic outlet). Where compression is mild and symptoms are intermittent, a structured non-operative trial is offered first. Where there is wasting or constant numbness, surgery is brought forward. Hand therapy with Ruby Doolan at Extend Rehabilitation is used selectively post-operatively for patients with significant pre-operative weakness.

Fees, Medicare rebates and the surgery-quote process are on the fees page. The case for seeing a fellowship-trained surgeon — and what fellowship training adds — is set out separately. GPs can find the referral pathway, urgency triage and what to include in the letter on the referrer page.

What this operation is billed under

The procedure is covered by the following Medicare Benefits Schedule items. Surgeon, anaesthetist, assistant, hospital and prosthesis fees are quoted separately and in writing before surgery — see the fees page for the practice's quote process and an explanation of why surgical fees follow the Australian Medical Association schedule. Surgery does not proceed without itemised written informed financial consent.

Item 39339 Revision cubital tunnel decompression

Used for revision of a previous in-situ release

Item 39329 Extensive neurolysis of ulnar nerve

Patient questions we hear most

• Will the numbness in my little finger go away?

  Intermittent symptoms — pins-and-needles when the elbow is bent, transient numbness — usually resolve quickly after release, often within the first few weeks. Constant numbness has been there longer and represents more sustained nerve compression; it can take six to twelve months to settle, and in long-standing cases some residual numbness can persist. The earlier the surgery is done in the disease course, the more complete the recovery tends to be.

• Will my hand strength come back?

  Pinch and grip strength supplied by the ulnar nerve typically improve over months. Visible wasting of the small hand muscles takes longer to reverse than numbness, and may not fully recover if it has been present for a long time. That's the case for not delaying surgery indefinitely once nerve-conduction studies confirm significant compression. Patients with mild wasting tend to recover most or all of their strength; patients with severe long-standing wasting often regain meaningful — but not complete — function.

• Do I need a transposition or just a release?

  Most patients do well with simple in-situ release — the cubital tunnel is opened up, the nerve stays where it is, and recovery is straightforward. Anterior transposition (moving the nerve to the front of the elbow) is reserved for the minority of patients in whom the nerve subluxes out of its groove with elbow flexion, or for revision after a failed in-situ release. The decision is made intra-operatively after testing the nerve's behaviour with the elbow flexed and extended. Published outcomes are similar between in-situ release and transposition in straightforward primary cases.

• How long is the recovery?

  There is no formal immobilisation period. Light activities resume immediately. Driving is reasonable once the dressing is comfortable, usually three to seven days. Manual work, gripping, and lifting are held off for four to six weeks while the deeper soft tissues heal. Numbness improvement is often noticed in the first weeks; strength recovery and full settlement can take three to six months.

• Is cubital tunnel release the same as ulnar nerve surgery?

  Yes — these terms refer to the same operation. Cubital tunnel syndrome describes the underlying condition; cubital tunnel release (or ulnar nerve decompression at the elbow, or ulnar nerve surgery at the elbow) describes the surgical treatment. Some patients have ulnar nerve compression at the wrist (Guyon's canal) instead of the elbow — that's a different operation and the diagnosis is sorted out at consult.

• How much does cubital tunnel surgery cost? What does Medicare cover?

  The procedure is performed under regional or general anaesthesia, so a separate anaesthetist gap applies on top of the surgeon and hospital fees. The practice quotes the surgical fee in writing before booking — Medicare item, rebate and out-of-pocket gap shown separately. Most major private health funds offer no-gap arrangements; the fees page sets out the full process. Surgery does not proceed without itemised written informed financial consent.
