Lengthening with no associated deformities can be carried out with specific internal devices, such as lengthening nails activated by the patient movement or specific magnetic remote controls. In these procedures, an osteotomy is performed and a lengthening nail is inserted. After consolidation, the device must be removed. In some cases, bone lengthening is carried out by using external fixation.
The Fitbone™ Intramedullary Limb-Lengthening System was developed in partnership with Professor Baumgart. The product was launched in 1997. Since then, this innovative treatment concept has grown into a global success story. The Fitbone TAA Intramedullary Lengthening system is intended for limb lengthening of the femur and tibia. With appropriate pre-operative planning, it is possible to ensure good limb alignment so that the limb is correct at the end of lengthening.
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.
