Background:
First described in 1882, Bennett's fracture is an intra-articular fracture of the first metacarpal associated with a dislocation of the carpometacarpal joint. Usually, open reduction internal fixation is used to manage such fractures. However, closed reduction has shown good outcomes recently. This meta-analysis compares closed reduction to open reduction internal fixation in the management of Bennett's fracture.
Methods:
PubMed, Cochrane, and Google Scholar (pages 1-20) were searched until August 2023. The clinical outcomes consisted of post-traumatic arthritis, grip and pinch strengths, range of motion, functional scores, and mean adduction deformity.
Results:
Six retrospective studies were included in this meta-analysis. Our results show higher grip and pinch strengths, better extension and flexion of the thumb, and lower mean adduction deformity in the open reduction internal fixation group.
Conclusion:
Higher grip and pinch strengths, better extension and flexion of the carpometacarpal joint, and a smaller mean adduction deformity of the thumb in the open reduction internal fixation group. No differences were seen in the remaining outcomes. However, a higher rate of complications is associated with open reduction internal fixation. Nevertheless, more randomized controlled studies are needed to confirm such results.
Level Of Evidence:
III.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
