This page contains information on the trapeziectomy procedure. You should ask your doctor or medical with any further questions you may have.
The cube-shaped bone which joins your thumb to your wrist is called the trapezium or the trapeziometacarpal joint (see figure 1).

This condition occurs when the joint is suffering deterioration. It is an on-going condition that wears away the covering of the cartilage, exposing the bone below to damage. Not surprisingly it can be very painful and cause immobility of the joint and lack of strength.
This surgical procedure helps to relieve pain and allows you to regain the use of your thumb and hand.
A simple alternative is to use a splint which will make the joint less painful – though it will be restrictive. Another alternative is to have a steroid injection into the joint to relieve the pain. Thirdly, you could have complete joint replacement using a metal/plastic artificial trapezium.
An alternative option for active younger patients is an arthrodesis. This procedure means a long-term option of screwing the two thumb bones together.
First of all you will receive one of several anaesthetic options and the surgeon will then operate for about an hour to an hour and a half.
The trapezium is accessed and removed via a small incision made in the back of the hand at the base of the thumb. To reconnect the wrist to the thumb, a ligament can be made from the tendon which travels past the trapezium.
The condition known as osteoarthritis of the thumb is a painful one. Having a trapeziectomy means relief from pain and improved mobility of both the thumb and hand.
