Trapeziumectomy
What is a Trapeziumectomy?
The trapezium is one of the eight wrist (carpal) bones which lies at the base of the thumb. The trapeziumectomy procedure involves the removal of the trapezium bone, filling the gap with a sling of tendon taken from the forearm. The procedure can result in some weakness in power and pinch grip, and so in some cases, patients may prefer to opt for fusion.
What should I expect after my Trapeziumectomy?
Following your trapeziumectomy your wrist will be placed in a cast and you will have limited use of your hand. Approximately two weeks after the operation, the wound will be cleaned and any visible stitches will be removed. There may be some initial bruising and swelling.
Following this you will see the hand therapist and a splint or further cast will be applied. This should be worn for a further four weeks. The hand therapist will give you advice regarding exercises to aid recovery. It is quite normal to lose strength in the thumb initially and it can take up to a year to regain this strength.
What are the risks of a Trapeziumectomy?
This type of hand and wrist operation is routine and complications are rare. There is a small risk of the following resulting from the procedure:
Infection – the risk is very low and can be managed well with antibiotics
Pain – the thumb may feel uncomfortable for up to six months, while the scar within the joint consolidates and settles
Stiffness – occasionally patients may have problems with increased stiffness in their hand following a trapeziumectomy
Nerve injury – localised numbness around the wound and over the thumb may occur, which usually resolves with time
When can I return to driving after a Trapeziumectomy?
You will not be able to drive for the first six weeks following the procedure.
