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.
