Study Design Prospective consecutive series. Objective To Evaluate the role of exchange nailing in non union of fractures of long bones of lower limb. Summary of Background data Exchange Nailing which includes removal of current intramedullary nail, reaming of medullary canal and placement of larger diameter nail shows increased union rate as seen in various studies. Methods A Prospective study of 25 cases of non union in fractues of tibia and femur previously operated with I. M Nailing were treated by Exchange Nailing and observations were made regarding various parameters like size of exchange nail and time of union of fracture.
