Bilateral Bennett's fracture: A case report

Salvatore Cassaro et al. Trauma Case Rep. .

Abstract

Bennet's fracture represents one of the most common injuries of the hand district, involving the base of the thumb, and it is affects children and elderly patients the most. The fracture is caused by direct axial trauma to a partially flexed first metacarpal and it is always intra-articular: the fracture line separates the palmar ulnar aspect of the first metacarpal base from the remaining first metacarpal. The fracture pattern is such that the first metacarpal shaft moves dorsally, proximally, and radially due to the pull of the abductor pollicis longus, extensor pollicis longus, extensor pollicis brevis, and the adductor pollicis brevis, which remain attached to the fracture fragment. The surgical treatment consists of closed reduction with percutaneous pinning or open reduction with either pins or interfragmentary screws. The decision to treat these fractures with either open reduction or closed reduction is still a matter of debate. To the best of our knowledge, there are no cases of bilateral Bennett's fracture reported in literature. The aim of this paper is to present a rare case of bilateral Bennet's fracture, the decision of two different treatments, and the good clinical outcomes.

Keywords: Bennet fracture; Bilateral fracture; Hand fracture; Percutaneous pinning; Surgical treatment.
