Trapezium and Bennett Fracture - A Rare Base Thumb Fracture Pattern:A Case Report

Trapezium fracture is a rare entity whose treatment is controversial. The reported cases range from conservative treatment to surgical treatment with good reported results.

This paper reports a clinical case of trapezium-metacarpal fracture-dislocation associated with trapezius fracture and Bennett fracture, surgically treated with excellent functional and radiological results. The patient underwent open reduction and internal fixation with two screws, excision of fragments, and reinsertion of the anterior oblique ligament. At the year of follow-up, the patient presented no mobility limitations and recovered grip strength.

This case study allows us to conclude that open reduction and internal fixation with screws of the dorsal trapezium ridge fractures with ligament repair of the anterior oblique ligament is a valid treatment with the reproduction of good clinical results.
