The Orthofix Limb Reconstruction System consists of an assembly of clamps ( usually two or three) which can The options for treatment with the LRS System. manipulate limb so that both pairs of bone screws are parallel. Apply LRS rail with standard straight clamps, and tighten clamp locking screws. Spacing screw. ➞. Using the rail fixator from Orthofix as an example (Orthofix LRS, Verona, Italy), these can be summarised as follows: There should be at least.

There should be at least three pins per segment of bone held by the fixator. Average lengthening achieved was 4. Table 3 Details of treatment. Positions 1 and 5 are used in the lgs and distal clamps.
Next, incise the orthofixx corresponding to the third seat of the distal clamp template. Conclusion The rationale and technique for femoral lengthening with a monolateral rail fixator have been described. Hydroxyapatite-coated pins should be considered mandatory when external fixators are used in lengthening.
Management of complex tibial and femoral nonunion using the Ilizarov technique, and its cost implication. Active involvement and participation of the patients is necessary for successful LRS treatment.
Orthofix Fixation System Medical Devices. Therefore, bifocal lengthening in the femur should not be used as a technique for congenitally short limbs.
Again, ensure the knee flexion technique is carried out. Soft tissues tend orthoffix prefer a slower rate of distraction and may be at risk of increased fibrosis if distracted at a faster rate [ 10 — 12 ].
The average shortening was 5. A Straight Clamp Template 2. General recommendations When using a rail fixator for femoral lengthening, several important principles can be used to ensure orhhofix control of the bone segments. This ensures central placement of the pin across the diameter of the femur.
Femoral lengthening with a rail external fixator: tips and tricks
The study was approved by ethical committee of our institution. Among these failed cases, one presented after 19 years of injury distal one-fourth tibia and underwent multiple earlier procedures. With circular systems, the possibility of correction of the deformity after lengthening is useful. This article has been cited by other articles in PMC. Principles of External Fixation.
Orthofix Limb Reconstruction
A 10—mm wide osteotome is then used to create a complete division of the lateral half of the circumference of the femur before the blade is advanced across the diameter of the bone Fig. The stability provided through the fixation device irrespective of whether this is external or internal is not static. The basic Application Technique for the LRS is now described, using as an example a three clamp assembly for bone transport in a femur with a medium-sized distal defect.
You are leaving the website of Orthofix International. Initially we managed with implant removal, radical debridement and fixed the nonunion with the LRS in operation theatre under all aseptic condition under suitable anesthesia under facility of an image intensifier [ Figure 1 ].

Part I, The Influence of stability of fixation and soft tissue preservation. In our patients the outcome of bony consolidation was better than functional llrs. Pain The higher peak forces and accompanying muscle orthofkx generated by bifocal lengthening produce greater pain.
Journal List Indian J Orthop v. Irrespective of the device used, close adherence to the principles of lengthening by Ilizarov [ 12 ], De Bastiani [ 3 ] and others is important. Control of segments Many devices are available for femoral lengthening. Use of a sandwich clamp in the middle is needed Fig.
Variables affecting time to bone healing during limb lengthening. Issues in femoral lengthening Muscle tension The muscles acting across the femur are responsible for many of the problems lrx arise during lengthening.
Management of complex long bone nonunions using limb reconstruction system
Insert the first pin using this knee flexion technique 1. Bone lengthening, Femur, External fixator. Augustin G, et al. Lower Extremity Product Gallery. The osteotomy is low energy and preserves the soft tissue envelope and vascularity. The osteotomy for lengthening orthofxi or without acute correction of deformity is performed in the same manner as described for the subtrochanteric region.
Many years of clinical experience have confirmed the efficacy of the device, providing good outcomes for the indications above as well as facilitating improvements over the original surgical technique. Circular and monolateral external orthoofix are used most commonly, although intramedullary devices are also popular for skeletally mature patients.
This can be minimised if the pins inserted into the distal segment are placed transfixing the quadriceps muscle in flexion. Separate Box For Instrumentation Tray contains the screw guides. Only then is the far cortex divided and the osteotomy completed by osteoclasis. National Center for Biotechnology InformationU.
