Palmar approach for fixation of metacarpal fractures.

Between 2018 and 2020, 14 patients with closed metacarpal fractures requiring open reduction were operated on via a palmar approach. Reduction and fixation were done with screws or plates. We assessed range of motion, grip strength, Mayo score, possible nerve damage and cosmesis. The range of motion and grip strength were fully restored by 6 months after operation. Transient paraesthesiae in the digital nerve territory occurred in two patients and had resolved by 3 months. In selected patients the palmar approach for metacarpal shaft fractures can provide satisfactory cosmesis and function of the hand. This method can be useful in patients with history of hypertrophic scarring or in patients who would prefer to avoid a visible scar on the dorsum of the hand.Level of evidence: IV.
