- Discussion:
- tend to rotate which is poorly tolerated;
- 5 deg of MCP rotation leads to > 1.5 cm of digital overlap;
- Operative Treatment:
-
screw fixation for metacarpal frx
-
screw menu;
- when ORIF is indicated, interfragmentary
lag screw fixation is used;
- in large adults, 2.7 mm screws are used;
- in smaller pts, 2.0 mm screws are used;
- if screws are used w/o a plate, requires that the frx length will be at least
twice diameter of the metacarpal;
- a minimum of at least 2 screws are used;
- 2 screws will provide sufficient resistance to shear & torsional stress;
