## TL;DR

This case report describes a rare hand injury combining a Bennett fracture-dislocation and a trapezium fracture, successfully treated with a minimally invasive K-wire technique.

## Contribution

The paper presents a rare combined hand injury and demonstrates the effectiveness of Iselin K-wire fixation in its treatment.

## Key findings

- The patient showed satisfactory clinical and radiological outcomes at six months post-treatment.
- Imaging was crucial for identifying the combined fractures and guiding treatment.
- Minimally invasive techniques like Iselin K-wire fixation can lead to good functional results.

## 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.
