External fixation is a surgical procedure for the treatment of fractured or deformed bones. It implies the use of a device – commonly called a fixator – worn outside the body. The fixator is connected to the bone with bone screws, or pins, that pass through the skin, and sometimes to muscles to connect the external fixator to the bone in order to hold the bone in place and to anchor the fixator securely. Sometimes wires are used with or instead of pins to hold the bone pieces in place. External fixation is an alternative procedure to internal fixation, and in some cases, the two methods are used in conjunction with each other. External fixation typically can be applied for temporary stabilization, fracture treatment, and management of deformities that are congenital or have arisen after healing from trauma injuries.
The Orthofix Limb Reconstruction System™ (LRS) is a series of modular monolateral external fixators used in reconstructive procedures for treatment of short stature, bone loss, open fractures, non-union, and angular deformities
The MiniRail External Fixation System consists of small rails and screws for fixation of small bones when a condition does not allow for implanting internal devices. The MiniRail is designed to help with a variety of deformity corrections and lengthening procedures of small bones and joints in the foot and upper limb.
The Ilizarov System has experienced many modifications over the last fifty years. The TrueLok™ Ring Fixation System, developed at Texas Scottish Rite Hospital for Children (TSRHC) in Dallas, Texas, is one of the modern variants of the original fixator, but preserves many of the original principles of Professor Ilizarov. It consists of aluminum rings available in different sizes, connected to the bone through metal wires or/and bone screws. The relative movements of the rings allow the correction of almost all the bone deformities in upper and lower limbs and in the foot.
TL-HEX is a dynamic, 3D external fixation system that combines hardware and software to correct bone deformities. This hexapod-based system functions as a 3D bone segment-repositioning module. In essence, the system consists of circular and semi-circular external supports secured to the bones by wires and half-pins, interconnected by six struts.
