Metacarpal fractures: treatment and complications.

Metacarpal fractures comprise between 18-44 % of all hand fractures. Non-thumb metacarpals account for around 88 % of all metacarpal fractures, with the fifth finger most commonly involved [19]. The majority of metacarpal fractures are isolated injuries, which are simple, closed, and stable. While many metacarpal fractures do well without surgery, there is a paucity of literature and persistent controversy to guide the treating physician on the best treatment algorithm. The purpose of this article is to review non-thumb metacarpal anatomy and treatment protocols for nonoperative management of stable fractures, and compare existing literature on surgical techniques for treatment of acute fractures and complications.
