What is a flexor tendon injury?
Flexor tendons are the strong bands of tissue that let you bend your fingers and thumb. They run from the muscles in your forearm into your hand, where they move through small tunnels of tissue that help keep them in place. As these tendons sit close to the skin on the palm side of your hand, they can be damaged by a deep cut. A tendon can also tear or pull away from the bone if a finger is forcefully pulled during sport. The injury may affect part of the tendon or go all the way through it. How much damage there is will usually shape the treatment you need.
What causes a flexor tendon injury?
A cut across the palm, finger or wrist is one of the most common ways to damage a flexor tendon.
An injury can also happen when a finger is pulled suddenly while you’re trying to keep it bent. This is sometimes called ‘Jersey finger’, and is often seen in contact sports when a finger catches on another player’s clothing.
Activities that place a lot of force through your fingers, such as climbing, can put these tendons under strain.
Some conditions, such as rheumatoid arthritis, which causes inflammation around the joints, can also weaken tendons and make them easier to injure.
What are the symptoms of a flexor tendon injury?
The clearest sign is often that a finger or thumb no longer bends as it normally would.
You may also notice:
- Pain when you try to bend the injured finger
- Tenderness around the injured area
- Numbness if a nearby nerve has also been affected
- A recent cut or pulling injury around the finger, palm or wrist
If you’ve had a deep cut and can’t move your finger normally afterwards, it’s important to have it checked promptly.
How is a flexor tendon injury diagnosed?
Your specialist will start by assessing the injury and asking you to move the affected finger or thumb. This helps them see which movements have been affected and how well the tendon is working. They’ll also check the feeling in your finger, as a deep cut can sometimes damage nearby nerves.
If the bone may have been injured, you might need an X-ray.
How is a flexor tendon injury treated?
Treatment depends on how badly the tendon has been damaged.
If only part of the tendon is torn, it may heal without an operation. A full tear usually needs surgery to rejoin it.
Your specialist will explain what they’ve found and what each option would mean for your recovery, so you know what to expect before treatment begins.

Treatment routes for a flexor tendon injury
Treatment is designed to help the tendon heal while keeping your hand moving as safely as possible. Your treatment plan will depend on the injury and how you use your hand each day.
A partial tendon tear may be treated with a splint, which supports your hand or finger while it heals.
You’ll usually be given specific exercises by your care team to help restore movement without putting too much pressure on the tendon. They’ll explain when you can safely start doing more activities involving your affected hand.
Recovery goals after a flexor tendon injury treatment
Phase 1 goals:
Protect the healing tendon with your splint Start the gentle movements recommended by your hand therapist
Phase 2 goals:
Gradually use your hand for lighter everyday tasks when advised Continue working on comfortable movement while the tendon becomes stronger
Phase 3 goals:
Build towards more demanding tasks as your strength returns Work towards the activities that matter to you
