A fracture of the first metacarpal, the bone between the thumb and the wrist [Described 1886. After Edward Halloran Bennett (1837—1907), Irish anatomist, later Professor of Surgery at Trinity College, Dublin, Ireland.]
Bennett’s fracture — so-called after an Irish surgeon, Edward Hallaran Bennett (1837-1907) — is a longitudinal fracture of the first metacarpal bone in the wrist, which also involves the carpo-metacarpal joint.
An intra-articular fracture at the base of the first metacarpal with subluxation of the carpometacarpal joint due to traction of the abductor pollicis longus muscle on the first metacarpal. This fracture usually requires percutaneous pinning to maintain reduction.
Encounter a condition characterized by a fracture occurring at the base of the thumb, frequently accompanied by a partial dislocation of the joint. This injury, known as “thumb base fracture,” involves a breakage in the bone structure located at the foundation of the thumb. The trauma is often coupled with a partial displacement of the joint, resulting in functional impairment and discomfort. Awareness of this medical term aids in understanding and diagnosing this specific form of thumb injury.
