Interlocking Nails are the preferred mode of treatment for fractures of long bone such as femur, tibia and humerus with minimal insertion. Presently, more than 95 per cent of femoral fractures and unstable tibial fractures can be treated with interlocking nails. Interlocking nails are inserted into the intramedullary canal and act as an immobilization device to hold the ends of the fractured bone. Different kinds of interlocking nails are designed to suit different requirements. The main function of intramedullary nailing is to help restore the shape of the fractured long bones to its natural, pre-injured state. The comprehensive system comprises intuitive instrumentation and a large choice of anatomical implants.
