Fracture of the Hook of Hamate

What is a fracture of the hook of hamate?

A hook of hamate fracture is a break in a small bone located near the base of the little finger, just above the wrist. Physiotherapy at Ace Physio Sports can play a crucial role in promoting recovery and restoring full hand function after this type of injury.

What causes a fracture of the hook of hamate?

The hook of hamate is commonly fractured as a result of a direct impact to the palm of the hand. This often occurs in sports such as hockey — for example, when the stick strikes the ground instead of the puck, forcefully driving the handle into the palm and causing a fracture of the hook of hamate.

What are the symptoms of a hook of hamate fracture?

A hook of hamate fracture typically causes pain on the little finger side of the palm and results in a weakened grip. Additional symptoms may include:

  • Tenderness when pressure is applied to the palm
  • Swelling or bruising in the affected area
  • Numbness or tingling in the ring and little fingers (if nearby nerves are irritated)
  • Pain during activities requiring grip strength, such as lifting or holding objects

What should I do if I think I have a fractured hook of hamate?

A fracture of the hook of hamate requires prompt medical attention. If you suspect this type of injury, you should immediately stop all activity and visit your nearest accident and emergency department for assessment. In the meantime, to help reduce pain and control swelling, apply ice to the palm. The most effective method is to use crushed ice wrapped in a moist towel or cloth and apply it to the affected area for up to 20 minutes at a time.

Fractured hook of hamate physiotherapy

Attending your nearest accident and emergency department is essential for the accurate diagnosis of a fractured hook of hamate. An X-ray or CT scan will be required to clearly assess the bones in your hand and wrist. Based on these findings, the most appropriate course of treatment can be determined. In some cases, surgery may be necessary to remove the fractured portion of the hook of hamate, followed by a brief period of immobilisation using a cast or splint to support healing.

Following the removal of your cast or splint, a physiotherapist can help alleviate your pain and guide you to regain full joint flexibility and muscle strength. Physiotherapy treatments may include:

  • Manual therapy: Techniques to improve joint mobility and reduce stiffness.
  • Targeted exercises: Strengthening and stretching exercises to restore normal hand and wrist function.
  • Electrotherapy: Modalities such as ultrasound or laser therapy to reduce pain and promote tissue healing.
  • Soft tissue mobilization: Approaches to improve scar tissue flexibility and reduce adhesions.
  • Functional training: Activities designed to support the return of everyday movements and enhance grip strength.

What should I avoid if I have a fractured hook of hamate?

If you have or suspect you have fractured your hook of hamate, you should avoid using the injured hand until it has been properly assessed by a medical professional. Continuing to use the hand may worsen the injury, delay healing, or lead to complications such as nerve irritation or long-term weakness. Seek immediate medical attention to ensure a correct diagnosis and appropriate treatment.

What are the long term effects of a hook of hamate fracture?

Unfortunately, hook of hamate fractures often do not heal on their own due to the difficulty in achieving effective immobilisation of the fracture site. Proper immobilisation is essential for the hook of hamate to reattach to the main body of the hamate bone. However, because this area is challenging to stabilise, surgical removal of the fractured fragment is frequently recommended. In most cases, surgical removal results in a full recovery with no long-term complications, and individuals are typically able to resume normal activities within a few months. However, if nearby structures—such as nerves—were damaged at the time of the fracture, recovery may take longer.
