Background: Trauma to the hand is very common and consequently, metacarpal fractures are not rare entities. Some of these fractures need surgery. Considering the diversity of surgical methods available for these kinds of fractures and also the importance of achieving full function and speedy return to work for patients that are mainly young workers or athletes, this study was undertaken to investigate the outcome of treating these fractures by mini-plates. Methods: Eighteen patients with open or comminuted fractures of metacarpal bones who were admitted to the emergency department of Sina Hospital between the years 2007 and 2010 underwent fixation surgery using mini-plates. Fourteen patients with 17 metacarpal fractures completed the study. Results: Thirteen out of 14 patients had complete fracture ::::union::::. The patient with non- ::::union:::: underwent revision surgery and bone graft. Four individuals developed an extensor lag of 15 degrees without functional impairment. Two patients had joint stiffness that was relieved after a period of physiotherapy and one developed wound dehiscence and discharge that improved with debridement and use of antibiotics without plate removal. Six patients had complaints regarding their hardware prominence and were satisfied after its removal. Overall, there was a 79% satisfaction rate upon the treatment. Conclusion: Despite the afore-mentioned complications, use of mini-plates seems to be a suitable treatment option for patients with comminuted metacarpal fractures. However, more studies with larger sample sizes are suggested to reach a firm conclusion.
