What is a ruptured FDP tendon?
The flexor digitorum profundus (FDP) is a muscle that has 4 tendons with one tendon attaching to the end of each finger on the palm side of the hand. A ruptured FDP tendon results in a person being unable to actively bend the end of their finger.
How long does it take a split tendon to heal?
Healing can take up to 12 weeks. The injured tendon may need to be supported with a splint or cast to take tension off of the repaired tendon. Physical therapy or occupational therapy is usually necessary to return movement in a safe manner. Expect movement to return gradually, with some stiffness.
How long does a damaged wrist tendon take to heal?
The repaired tendon will usually be back to full strength after about 12 weeks, but it can take up to 6 months to regain the full range of movement. Some people may never be able to move the affected finger or thumb as much as before it was damaged.
Can a flexor tendon be repaired?
Surgery will be required in order to repair the damaged tendon. A small incision is made to locate the ends of the tendon and they are then stitched back together. Flexor tendons are often difficult to get to and are located near important nerves so repair will generally occur under a general anaesthetic.
How do I test FDP?
The FDS to the middle finger is tested by holding the other 3 fingers in full extension, thereby immobilizing the profundis [FDP] (shown in black), and asking the patient to “bend the finger.” Note that the FDP flexes the DIP specifically, but will also flex the PIP indirectly as well.
What are the symptoms of a torn tendon in the foot?
When tendons become injured or torn, it can cause pain, swelling, weakness in the foot and ankle, and discomfort when standing, walking or playing sports.
What are the symptoms of a torn tendon in wrist?
Hand, elbow or wrist tendon injury symptoms
- Pain.
- Swelling.
- Bruising.
- Weakness in the affected area.
- A snapping or popping noise at the time of injury.
- Difficulty moving the hand, wrist or elbow.

What does a torn tendon in wrist feel like?
A torn ligament in the wrist is sometimes mistaken as a sprain. You might feel pain in the wrist at the time of the injury, and pain while moving the wrist after the injury. Even with rest, the pain may not decrease significantly, and there may be swelling, bruising, or a feeling of popping or tearing in your wrist.
What is the difference between FDP and FDS tendons?
FDP inserts at the base of the distal phalanx and flexes the DIP joint (tip: FD P is at the p oint of the finger). The FDS tendon divides into two slips that wrap around the FDP to insert into the sides of the middle phalanx. FDS flexes the PIP joint. The flexor tendons are enclosed in a synovial sheath that lubricates them and minimizes friction.
Where does the FDP tendon insert?
FDP inserts at the base of the distal phalanx and flexes the DIP joint (tip: FD P is at the p oint of the finger). The FDS tendon divides into two slips that wrap around the FDP to insert into the sides of the middle phalanx.
How do you test for FDs and FDP tendons?
The FDS and FDP tendons should be tested individually; it is not enough just to observe the child make a fist as tendon injuries can be easily overlooked or missed. To check FDS function, hold all adjacent fingers in extension and then release the finger you want to assess. Ask the child to flex the free digit at the PIP joint.
What are the flexor tendons of the thumb?
The flexor digitorum superficialis ( FDS) and flexor digitorum profundus ( FDP) are the flexor tendons of the fingers, and the flexor pollicis longus ( FPL) is the only thumb flexor. The flexor tendons travel distally from the forearm through the carpal tunnel and are named based on the forearm muscles from which they arise.
