What is Benett fracture dislocation?

Bennet fracture dislocation is a break at the base of the thumb near the joint that attaches the thumb to the wrist. It is associated with a dislocation of the bones. The most common injuries are from contact sports, such as football or boxing, as well as a fall onto the thumb. In most cases, the thumb is forced outward, away from the palm, farther than normal movement. 

What are the symptoms of Bennett fracture dislocation?

When does a Bennett fracture dislocation require surgery?

Dr. Azouz will review x-ray images of the hand to view the alignment of the bones and confirm the location of the fracture. In some minor cases, the fractured bone can be reduced and splinted for 4-6 weeks. However, surgery is usually recommended for optimal treatment, especially if the bone is broken in several places.

How is a Bennett fracture-dislocation surgery performed?

Dr. Azouz will repair the fracture with pins or screws. The displaced joint is reduced back into place. He will also repair any nearby damaged ligaments, nerves, or blood vessels.

What is the anesthesia for a Bennett fracture-dislocation surgery?

Dr. Azouz uses sedation and local anesthesia for the majority of hand surgeries. His patients are sedated in a deep sleep to help them relax. Dr. Azouz will inject a numbing medication that helps control pain and lasts for up to 24 hours.

What is the recovery for a Bennett fracture-dislocation surgery?

After the procedure, Dr. Azouz will routinely place a splint over the hand and wrist, which is usually worn for 4-6 weeks. Routine follow-up visits will be scheduled to monitor progress and to give instructions for caring for the pins. Dr. Azouz will also assess recovery to determine when patients can return to activities.

What is the cost of a Bennett fracture-dislocation surgery?

The cost of surgery varies widely and is dependent on the type of injury. Dr. Azouz will assess the injury with a medical history and physical examination. If there is a work-related injury, workers’ compensation carriers usually cover the cost if it is deemed medically necessary.
