The right size depends on the bone and surgical site the Standard 5½" works well for small bones like phalanges or hand bones, while the Medium 6" suits mid-sized areas like the wrist, ankle, or smaller long bone fragments. For larger bones such as the femur or tibia, the Large 8" gives you the wider jaw span and stronger grip needed to hold bigger fragments securely. Always match the clamp size to the fragment thickness and surgical depth to maintain stable, damage-free fixation throughout the procedure.
