Limb - lengthening using IM nails has satisfactory outcomes
American Academy of Orthopaedic Surgeons, Saturday, March 18, 2000
[for Professionals mainly]
The Ilizarov fixator, a circular frame and tensioned wires, has many benefits that accelerate bone union through early weight bearing and allows correction of angulation, translation and rotation during the lengthening period, the researchers said. However, there are disadvantages such as pin site infection, limitation of joint motion by soft tissue fixation, patient discomfort because of bulky size and greater risk of neurovascular injury, they said.
Developed by J.M. Guichet, MD, in 1986, the GEN diaphyseal lengthening system gradually lengthens long bone using an intramedullary nail ...
