Metacarpal fractures are some of the most common hand injuries encountered in plastic surgery — and knowing when to treat conservatively versus when to operate is critical. In this episode, we review evidence-based management of metacarpal fractures, focusing on nonoperative thresholds, fixation techniques, and practical surgical pearls.
Key topics include:
Nonoperative care: Angulation tolerances by digit, when splinting is enough, and why rotational deformity is never acceptable.
Operative indications: Shortening >5 mm, articular step-off >1 mm, or >25% articular involvement .
Fixation techniques: Percutaneous K-wires, plates, lag screws, intramedullary fixation, and external fixation — with pros/cons for each .
Thumb metacarpal base fractures: Why Bennett and Rolando fractures demand surgical attention.
Comparative studies: Evidence suggesting intramedullary pinning may offer superior outcomes for fifth metacarpal neck fractures .
By the end of this episode, you’ll have a framework for approaching metacarpal fractures in both hand call and exam scenarios.
