Wrist Replacement (Wrist Arthroplasty) is a surgical procedure in which the diseased or damaged joint is replaced with an artificial joint(prosthesis). Young active patients and individuals with high physical demands are not considered good candidates for Total Wrist Replacement.
Symptoms:
- Pain
- Stiffness
- Swelling
- Reduced range of motion
Indications:
- Wrist Osteoarthritis
- Rheumatoid arthritis
- Post traumatic arthritis
Anaesthesia:
Wrist replacement is carried out under general or regional anaesthesia.
Implant components:
Implants are made from plastic and metal. It has two components:
1.Radial Component:
This fits against the end of the radius bone. It is made up of two pieces: Flat metal piece with a stem that attaches down into the canal of the bone and a plastic cup that fits onto the metal piece, forming a socket.
2. Distal Component:
This replaces the small wrist bones. It is globe shaped that fits into plastic socket on the end of the radius. It is attached by two metal stems that fits into hollow bone marrow cavities of the carpal and metacarpal bones of the hand.
Recovery:
You will be in recovery room for about 3-4 hrs under anaesthetist observation, following this you can be shifted to the room.
The surgeon will instruct you regarding home care during initial weeks of surgery.
Wound Care:
The surgeon will apply stitches or staples to close the wound and they will be removed approximately two weeks after surgery. You should avoid getting the wound wet.
Diet:
A balanced diet with calcium and iron supplements is necessary for tissue healing and muscle strength. Make sure you drink lots of fluids. There is no diet restriction unless you are diabetic or have been advised earlier.
Activity:
Regaining function of the hand following TWA is largely dependent on post-operative physiotherapy. Physiotherapy should be started early beginning with gentle mobilization exercises and gradually progressing to resisted exercises.
