Gavriil Abramovich Ilizarov is the orthopedic surgeon who pioneered this technique. The Ilizarov technique is used in surgical processes to treat open or complex bone fractures, to reshape or lengthen the limb bones and also the cases of infected non-unions of bones that cannot be treated with any other technique.
The Ilizarov Apparatus is comprised of external fixators such as rods, Kirschner’s wires and rings. The Ilizarov apparatus is unlike the conventional external fixators. Those fixators consist of the limb just like in the shape of a cylinder and makes use of wires instead of pins so as to fix the bone to the rings.
The Ilizarov’s Principle of Distraction Osteogenesis is used for Ilizarov Limb Lengthening Method. The new bone is introduced in between the bone surfaces which has been carefully and gradually pulled in a controlled manner. The Neovascularisation is the result of the initial distraction that stimulates the formation of a new bone. Simultaneously, there is histogenesis of skin, muscles and nerves. The new bone in bone diseases (pseudo-arthrosis, osteomyelitis and fibrous dysplasia) replaces the pathological bone with the normal bone. This is regarded as the revolutionary concept and with the help of Ilizarov Technique, many diseases are successfully treated that earlier had no treatment.
Some bunions occur over the years while the other may progress rapidly. Some bunions are painful while the others are not and not this does not depend on the size. Following are the causes:
Transosseous Osteosyntheis is the other name used for limb lengthening procedure. By making use of drill, the 1.5 mm diameter wires are then passed through the skin and bones. The extended ends of the wires are fixed to rings with unique wire-fixation bolts. All these rings are fixed and connected with each other with the help of threaded rods. When the rings are properly fixed, the Ilizarov frame gets a steady support to the affected limb. The Corticotomy procedure is then performed which means cutting the bone (osteotomy) where the bone’s periosteum is preserved. The distraction is produced by making adjustments in the rods as preferred in between the bone ends and all the deformities also gets corrected. After the procedure the external ring fixator is also removed.
This surgery is also known as bone shortening, femoral lengthening, bone lengthening and femoral shortening. The aim of this surgery is to correct LLD and connected deformities by protecting the function of joints and muscles. The surgery is done for-
Height lengthening (limb lengthening) is a modern day procedure and this minimally invasive procedure is performed by making a surgical cut in the thigh bones or in the leg, in order to promote the mending and lengthening of any leg deformities. The deformity correction technique is used to replace the missing bone or to straighten or lengthen the bone deformed segments. Both children and adults can benefit from this procedure and it eliminates deformities which is due to injuries, birth defects, knock-knee deformities, trauma and the bow-legged patients having one leg shorter than the other leg. Distraction Osteogenesis is the procedure by which the correction of deformities and lengthening of the bones is done when there is gradually growing of soft tissue sand new bone.
