- MP collateral ligament injury:
- injury mechanism: finger is flexed and forced to one side (w/ radial injury, the finger is flexed in an ulnar direction);
- indications for ORIF:
- wide displacement of avulsion chip ( > 2-3 mm) on x-ray;
- if fragment involves > 20% of articular surface;
- ulnar collateral ligament injuries (or frx) in the little MP joint should be treated more aggressively than injuries involving the other
digits because the abductor digiti quinti will pull the digit in an ulnar direction;
