A doctor may place the hand in a splint to protect it while it heals.
Tendons cannot heal unless the ends are touching. This does not not occur in a complete tear. In most cases, a torn tendon must be repaired surgically – the sooner the better.
Recovery improves when surgery is performed soon after the injury occurs and is normally performed 7-10 days after an injury.
Surgical:
There are several different procedures to repair a torn tendon depending on the nature of the tear. Tears can be straight across, torn at an angle and pulled from the bone. Each specialized surgical procedure includes special sutures or stitches as they are commonly called.
