Interlocking medullary nails have been widely used in the treatment of long bone fractures especially in tibia and femur. But with increasing use of nails, many preoperative, intra-operative and post-operative complications have been reported. We have experienced 3 cases of very rare complication, fracture of tibia shaft which occurred during removal of interlocking medullary nail after complete healing of original tibial fracture. We report these rare complications with literature review.
