Flexor tendons help control movement in the hand. An injury to the forearm, fingers, thumb, wrist, or hand can damage the flexor tendons and affect movement. Symptoms include pain and the inability to move the hand, fingers, or thumbs. Injuries are usually caused by a deep cut, or an athletic injury, but rheumatoid arthritis can also weaken the flexor tendons, causing them to tear.

Treatments for Flexor Tendon Injuries


A splint, also known as a brace, is a rigid device that holds a body part in place so that it is unable to move. It is usually used as a treatment for a suspected fracture, sprain/ligament damage, or other injury. It can be applied by first responders in the event of trauma. Splints can reduce pain, aid in proper healing, and can also prevent further injury. They can be worn for several days or weeks to hold the body part in place for the duration of healing time.

Surgery for Flexor Tendon Injuries

Tendons can tear straight across, at an angle, or be pulled right off of the bone, so there are many different methods surgeons use to repair them. All the methods involve sutures, also known as stitches. Flexor tendon surgery is typically an outpatient procedure; the doctor applies a dressing and splint, and the patient goes home on the same day of the surgery. The patient's fingers and wrist will be placed in a bent position to keep tension off the repaired tendon.
