Jersey Finger

Jersey finger is an injury to the tendon that bends the tip of the finger. It occurs when the tendon is forcefully pulled away from the bone, often during activities where the finger is suddenly straightened while gripping.

This injury commonly occurs in contact sports, such as rugby, when a player grabs another player’s clothing and the finger is forcibly extended.

The result is an inability to bend the fingertip, which can significantly affect grip and hand function. Early assessment is important, as this injury usually requires surgical repair for the best outcome.

‍

Diagnosis is based on clinical assessment, including examination of finger movement.

The inability to actively bend the fingertip is a key finding.

X-rays may be performed to check for an associated fracture.

‍

Jersey finger typically requires surgical treatment.

Initial management may include:

• Splinting to protect the finger
• Avoiding further use

Definitive treatment usually involves surgical repair of the tendon, followed by a structured rehabilitation programme.

‍

Surgical repair involves reattaching the tendon to the bone.

The procedure is typically performed under regional or general anaesthetic. The aim is to restore tendon function and allow the finger to bend normally.

Following surgery, the tendon must be protected during healing.

‍

Recovery following surgery is structured and closely supervised.

Recovery typically involves:

• Use of a protective splint
• Early controlled movement guided by hand therapy
• Gradual return to normal function over time

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:

• Infection (around 1%), usually treated with antibiotics
• Swelling or stiffness, which may take time to settle
• Scar sensitivity
• Nerve irritation or injury (rare)
• Ongoing pain or discomfort, which typically improves over time
• Recurrence of symptoms (uncommon)
• Residual symptoms, particularly if the condition was advanced before treatment
• Tendon rupture or failure of repair
• Reduced range of movement

Very rarely, a condition known as complex regional pain syndrome (CRPS) can occur, leading to prolonged pain and sensitivity.

You should seek urgent medical advice if you are unable to bend the tip of your finger following an injury.

Early treatment is important, as delayed repair can affect recovery and long-term function.
