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.

As with all types of devices used for femoral lengthening, the surgeon needs to appreciate the strengths and weaknesses of each and use the most appropriate.

In this example, proximal lengthening is combined with distal acute correction of a valgus deformity, b Lateral view of oethofix case in a where a sandwich clamp is used to ensure good purchase of the pins either on or near to the mid-axis of the femur. Orthofix Fixation System Medical Devices. Ilizarov treatment of tibial nonunions with bone loss.

Sites for lengthening The usual chosen sites of femoral osteotomy for lengthening are metaphyseal regions, often the subtrochanteric or supracondylar areas. Patients with foreign body sensitivity where material sensitivity is suspected, tests should be made prior to implanting.

If a bifocal lengthening is planned with the osteotomies in the subtrochanteric and supracondylar regions, the following sequence of screw insertion may minimise the problem of the curved sagittal profile. This rule applied to all our patients.

The drill is then placed in the middle of these two limits. Adult System3 includes krs definitive standard series of clamps and the Acute Correction Templates. National Center for Biotechnology InformationU.

However, whilst this is eminently possible when applying a straight rail to a straight bone, the sagittal profile of the femur is curved and some screws will inevitably not lie across the diameter of the bone. Final results of our study is shown in [ Table 4 ]. This is probably due to people of this age group are more prone for open fractures of long bones secondary to high velocity trauma RTA. This orthfix refused further treatment. Once radiological union of fracture site was visualized, 4 weeks were given for the consolidation and at the same time the corticotomy site was assessed.

Orthofi Titanium Femoral Nail. However, since we could not certainly exclude the possible future reactivation of infection, absence of discharging sinus for a minimum of 12 orthodix was considered as success. Distraction at corticotomy site was started on the seventh postoperative day.

Femoral lengthening with a rail external fixator: tips and tricks

In clinical practice, this effect only becomes significant if there was a preexisting valgus deformity in the femur and therefore a lateral shift of the mechanical axis already present; the lengthening along the anatomical axis will then accentuate this lateral shift of the axis and make it clinically significant. Thermal necrosis produced at the time of drilling is a cause of ring sequestra from local pin site infections. The incision is either longitudinal or transverse and the fascial incision likewise.

Simpson AH, et al. Patients with severe osteoporosis, patients who are HIV positive and patients with severe, poorly controlled diabetes mellitus. In our patients the outcome of bony consolidation was better than functional results.

Obstacles represented difficulties that required an operative intervention. Lower Extremity Product Gallery. Several strategies have been described for overcoming this problem.

The most important disadvantage of distal femoral lengthening is interference with knee movement range. The distal template is positioned in the usual position for a supracondylar osteotomy. Clin Orthop Relat Res.

National Center for Biotechnology InformationU. This is a prospective study carried out between April and September Higher peak forces may also be generated during the lengthening process, particularly so in congenitally short limbs. Hydroxyapatite-coated pins should be considered mandatory when external fixators are used in lengthening. Lengthening along the anatomical axis in the femur produces a medialisation of the knee and consequently, a lateral shift of the mechanical axis. Tray contains the screw guides.

Fourteen cases presented with infected implants. Stainless Steel Antegrade Nails. This arises because of quadriceps transfixation and tethering of the iliotibial band. When using a rail fixator for femoral lengthening, several important principles can be used to ensure optimal control of the bone segments.

Final 30 cases were subjected to thorough clinical, systemic and local evaluation. In the proximal clamp, screw seats 1, 2 and 4 numbered from the proposed osteotomy siteshould be used. Order of pin insertion It is helpful to insert the most distal pin of the proximal clamp first Fig.

ortofix It provides stable external fixation with the capacity to change the stiffness of fixation, and therefore, the fracture environment can be more precisely controlled.

There was no major complications like radial nerve palsy and joint stiffness, Furthermore, the monolateral axial external fixator was tolerated well and allowed movements of shoulder and elbow throughout the period of treatment. Orthofix Limb Reconstruction System.

Pin loosening was managed by pin reinsertion and intravenous antibiotics.
