Bennett's fracture
Bennett's Fracture
Bennett's fracture (pronounced: BEN-its FRAK-chur) is a type of fracture that occurs at the base of the thumb, specifically affecting the first metacarpal bone. It is named after the Irish surgeon, Edward Hallaran Bennett, who first described it in 1882.
Etymology
The term "Bennett's fracture" is derived from the name of the surgeon who first described this condition, Edward Hallaran Bennett. The word "fracture" comes from the Latin fractura, meaning "a break".
Description
Bennett's fracture is a fracture-dislocation of the base of the first metacarpal bone, which forms the knuckle of the thumb. This injury is typically caused by a forceful impact, such as a punch or fall onto an outstretched hand. The fracture is intra-articular, meaning it extends into the joint space of the carpometacarpal joint (CMC), which can lead to arthritis if not properly treated.
Related Terms
- Fracture: A break in the continuity of the bone.
- Metacarpal bones: The five bones in the hand that connect the wrist to the fingers.
- Carpometacarpal joint (CMC): The joint at the base of the thumb, which is involved in Bennett's fracture.
- Arthritis: Inflammation of one or more joints, which can result from a poorly treated Bennett's fracture.
Treatment
Treatment of Bennett's fracture typically involves surgery to realign the fractured bone and joint. This is often followed by a period of immobilization with a cast or splint. Physical therapy may also be recommended to restore strength and mobility to the thumb.
