Flexor tendon injuries affect the tendons that allow you to bend your fingers and thumb. These tendons run from the forearm into the hand and fingers and are essential for grip and fine movement.
Injury usually occurs following a cut to the hand or fingers, although it can also result from forceful trauma. Because these tendons sit close to the skin, they can be damaged even by relatively small wounds.
A flexor tendon injury often results in an inability to bend the affected finger or thumb. Prompt assessment is important, as early treatment gives the best chance of restoring movement and function
Symptoms usually occur immediately after injury and may include:
In some cases, movement may be partially affected depending on the extent of the injury.
Symptoms usually occur immediately after injury and may include:
In some cases, movement may be partially affected depending on the extent of the injury.
Diagnosis is based on clinical assessment, including examination of finger movement and tendon function.
The inability to actively bend a finger or thumb is a key finding.
Imaging is not always required but may be used in more complex cases to assess associated injuries.
Flexor tendon injuries usually require surgical repair.
Initial management may include:
Definitive treatment typically involves surgical repair of the tendon, followed by a structured rehabilitation programme.
Surgical repair involves rejoining the ends of the damaged tendon using specialised techniques.
The procedure is typically performed under regional or general anaesthetic. The aim is to restore tendon continuity and allow movement to return.
Following repair, the tendon must be protected while it heals.
Recovery following flexor tendon repair is structured and closely supervised.
Recovery typically involves:
Full recovery can take several months, and adherence to rehabilitation is essential for a good outcome.
As with any surgical procedure, there are potential risks, although these are uncommon.
Possible complications include:
Your surgeon will discuss the expected outcomes and risks before treatment.
You should seek urgent medical assessment if you are unable to bend a finger or thumb following an injury, particularly if there is a cut to the hand.
Early treatment is important, as delayed repair can affect recovery and long-term hand function.
