COMPARATIVE ANALYSIS OF THE THREE NEW DESIGNS OF TIBIAL NAILS WHICH ELIMINATE THE USE OF ORTHOPEDIC SCREWS

Abstract

The idea to design a tibial nail which eliminate the use of orthopedic screws was given by the study of surgical techniques imposed by the classical tibial nails. Classical nails had some important disadvantages as the difficulty of manipulation and positioning in the bone and, in the same time, the complicate orientation and displacement of the distal screws using the nail guide. Also, all these operations can give failures or/and wrong holes in the bone which can make tibia more breakable. In the same time, all these extra-operations can increase the surgical operation time with unpredictable effects for the fixation of the fracture. All these three design of the tibial nail proposed by our multi -disciplinary team have one single principle, different as the classical nails: the attachment of the nail to the bone is made in the medullary tibial channel using metallic components.
