A bone clamp having a ratchet mechanism including ratchet teeth having rounded peaks with curved valleys therebetween and a curved pawl having a curvature similar to the valleys spanning the peaks of the ratchet teeth. The ratchet mechanism of the current invention distributes the interaction forces between the ratchet teeth and the pawl and therefore is resistive to shear stresses which could otherwise compromise the structural integrity of the ratchet mechanism.
