Abstract
The combination of a trapezium fracture and a Bennett fracture-dislocation is rare in hand trauma, posing both diagnostic and therapeutic challenges. Anatomical reduction and stabilization of the thumb metacarpophalangeal (MCP) joint, along with optimal management, are key to achieving a good outcome. We present the case of a 20-year-old motorcyclist with this lesion, treated with closed reduction using the Iselin K-wire fixation. Clinical and radiological results were satisfactory at six months follow-up. This case highlights the importance of imaging to detect combined lesions and emphasizes the role of minimally invasive fixation techniques for good results.
