Boxer's Fracture

The purpose of this prospective randomized controlled clinical trial is to evaluate if functional treatment leads to a better functional outcome than a forearm cast and a finger splint in patients with fifth metacarpal neck fracture.

The goal of this clinical trial is to compare two different intramedullary fixation technique in patient diagnosed with deplased fifth metacarpal neck fracture. The main questions it aims to answer are: * Can percutaneous screw application be a more stable fixation method than intramedullary elastic nail application? * Can screw application create a significant difference in the recovery of grip strength in the early period compared to elastic nail application? Patients will be followed up at the 1st week, 1st month and 3rd month postoperatively. Functionality will be evaluated with Quick DASH score at the 3rd month. At the 1st and 3rd month controls, grip strength will be evaluated. At the same time, metacarpal shortening and angulations will be measured on x-ray. Researchers will compare percutaneous screw and elastic nail group to see grip strength, healing time and radiologic parameter difference.
