Trapeziectomy
(Base of Thumb Arthritis)

Relieve pain. Regain control. Restore your lifestyle.

What is a Trapeziectomy?

Trapeziectomy is a surgical procedure to treat arthritis at the base of the thumb — a common condition that can cause pain, weakness, and reduced function. The arthritis occurs at the joint between the thumb metacarpal and a small wrist bone called the trapezium.

Symptoms of Base of Thumb Arthritis

  • Pain during pinch movements (e.g. opening jars or peeling vegetables)
  • Weak grip strength due to pain
  • Swelling or a square-shaped appearance at the thumb base
  • A thumb that appears crooked or twisted
  • Resting or night-time thumb pain

Non-Surgical Treatment Options

If you’re experiencing significant joint pain in the thumb, there are several non-surgical treatments available to help relieve discomfort and improve function.

Medications

Your clinician may recommend the following:

  • Topical Treatments applied directly to the skin over the affected joint
    • Capsaicin cream – reduces pain by interfering with pain signals
    • Diclofenac gel – an anti-inflammatory that helps reduce swelling and ease discomfort
  • Over-the-Counter Pain Relief
    • Paracetamol – suitable for mild pain
    • Non-steroidal anti-inflammatory drugs (NSAIDs) – such as ibuprofen which helps relieve both pain and inflammation
  • Prescription Medications
    • Celecoxib – a prescription NSAID for more persistent pain
    • Tramadol – a stronger option that may be used short-term for more severe symptoms

Splinting

A splint helps support your joint and limit movement. It does not cure the problem but reduces the symptoms of the arthritis. You may be advised to wear a splint either just at night only to promote healing during rest, or throughout the day and night for more advanced pain or instability. The benefits of splinting include

  • Reducing strain on the joint
  • Promoting better alignment during daily tasks
  • Providing rest and support to aid healing

Injections

If medications and splinting do not provide sufficient relief, injections may be recommended. These injections deliver anti-inflammatory, lubricating or regenerative medication directly into the affected joint, helping to:

  • Reduce inflammation
  • Provide temporary but significant pain relief
  • Delay the need for more invasive treatments
  • Promote recovery

Trapeziectomy Surgery at Sozo

If non-operative treatments fail, surgery may be recommended. This aims to remove the trapezium bone to get rid of the arthritis pain. This is performed through a small incision either on the front or the back of the thumb. In the gap that is lift behind by removing the bone, a part of one of your tendons is placed to provide a cushion for movement. Sometimes that same tendon is used to reconstruct the ligament at the base of the thumb to improve the stability of the thumb.

What to expect after your operation

  • Stitches that are usually buried under the skin
  • A plaster cast and bandage which must be worn for the first 2 weeks
  • At 2 weeks, the scar will be uncovered and the cast switched for a lighter splint.
  • Swelling is normal and should reduce over time. Elevating your hand above your heart can reduce this.
  • Some pain for a number of weeks is also normal.
  • You will need to do some exercises in order to regain the movement of your thumb.
  • It usually takes approximately 12 weeks after surgery to recover.

What to Expect

  • Procedure Time: 45-60 minutes

  • Anaesthesia: Awake under local or regional anaesthetic

  • Same-Day Discharge: usually within 30 minutes of the procedure

  • Physiotherapy will be required and we will refer you to one of our Sozo Physio partners

  • Recovery: 12 weeks minimum

Risks & Complications

While rare, these may include:

  • Bleeding or wound infection

  • Ongoing pain or stiffness of the hand

  • Scar pain and tenderness

  • Chronic Regional Pain Syndrome

  • Permanent numbness or weakness of the thumb/hand
