Background: Metacarpal fractures either closed or open are common injuries and may account the most common fractures in the skeletal system. These fractures can be treated conservatively or operatively depending on the nature of the injury, fractures pattern and stability. Objective: To assess the functional outcome of injuries of metacarpal fractures after fixation by mini external fixator. Patients and Methods: This study was carried out on 15 patients presented with fractures in their metacarpals between February 2017 and November 2017 in the Orthopedics and Traumatology Department in Mahalla General Hospital. The study included. The mini-external fixator was used to fix the fractures within the first 24 hours and patients were followed up for 6-8 weeks with an average period of 7 weeks. Results: 13 patients were satisfied with this fixation by mini external fixator with full range of motion.
