Abstract
Orthopaedic screws play a major role in treatment of orthopaedic injuries such as fracture fixation, tendon and ligament injuries and limb alignment and lengthening and shortening procedures. These screws have evolved over the years, and improved in terms of pullout strength and the site of fixation.
Though there was not much evolutionary design in orthopaedic screws, after the advent of AO trauma in 1958 by Maurice Muller and other Swiz surgeons, machine screws has gained its importance and evolved according to the fixation methods.
The parts of the screw are head, shaft, thread and tip. Each has its own significance. Screws are classified according to the size, shape, biomechanical property, material design and special screws. The two types of machine screws include cortical and cancellous screws. Special screws include Herbert screws, Interfragmentary screws, Pedicle screws and malleolar screws.
The other types of screws include dynamic hip screw, locking bolt, condylar screw and mini screw.
Currently, there has been a recent shift in the process of development of bioabsorbable screws, gained importance in intra-articular fracture fixation and ligament injury fixation.
