BackgroundMetacarpal fractures are among the most common fractures of the hand. They may lead to loss of function if treated improperly. These injuries can be treated conservatively. However, if significant shortening, rotational deformity and angulation occur, surgical treatment is required. In this article, results of metacarpal fractures treated with open reduction and internal fixation with mini plates were presented.MethodsWe retrospectively reviewed the clinical and radiologic records of twenty-nine consecutive patients with 37 metacarpal fractures treated by open reduction and internal fixation with low profile mini plate fixation between 2006 and 2013. Surgical treatment with dorsal approach was planned for cases with unacceptable shortening, rotational deformity, and angulation. Early active motion was begun in all cases postoperatively. Patients were permitted to use their hands in daily activities four weeks after surgery. For objective assessment, total range of joint motion was measured. Rotational deformity of the fingers was assessed. Grip strength and quick DASH scores were compared with the uninjured side. Metacarpal shortening was evaluated radiologically, and angulation was measured.ResultsMean age was 35.1 years (19-61 years) and mean follow-up period was 32 months (6-39 months). While mean operation time was 8.48 days (2-23 days), mean shortening was 7.58 (2-30) mm. In cases with radiologically documented union, mean angulation in the posteroanterior plane was 8.13 (0-42) degrees preoperatively and 3.55 (0-28) degrees postoperatively. In lateral X-rays, mean angulation was 8.22 (0-39) degrees preoperatively and 3.66 (0-28) degrees postoperatively. Mean quick DASH score was 3.6 (0-11.4). Mean grip strength measurements by Jamar hand dynamometer were 41.05 (±8.3) kg for fractured hands, 44.7 (±9) kg for normal hands. No significant relationship was found between normal hand and fracture hand by Mann-Whitney U test.ConclusionAs in general fracture treatment principles, goals in metacarpal fracture treatment are obtaining an anatomical and stable reduction, fracture union and beginning early movement to avoid loss of function. Open reduction and low profile titanium plate application in metacarpal fractures is the choice of treatment in suitable cases as it meets the above mentioned treatment principles.
