Intra medullary rods are used mainly to align the broken bones and to prevent further dislocation of bones. IM rods are placed into the bone marrow canal. During the procedure a ball tipped guided wire is used to insert the nails and rods. The fluoroscopic images are used to confirm the position of the instruments. Mallet or hammer is used to drive pins into the medullary canal thereby preventing the rotation of the pins.

AMPUTATION refers to the surgical removal of the limb or extremity. It can be classified into above knee or below knee amputation. Myodesis refers to a surgical technique in amputation in which the muscles is attached to the bone directly in order to stabilize the bone.
