LRS ORTHOFIX PDF
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.

The Orthofix Limb Reconstruction System LRS is a series of modular monolateral external fixators to be used in reconstructive procedures for treatment of: Mean residual orthofi length discrepancy was 1.
This arrangement of 4 template clamps is not often needed but provides additional stability for lengthening in long femora Fig. In other case, orthofic were neither able to control infection, nor achieve union. Final 30 cases were subjected to thorough clinical, systemic and local evaluation. This is then followed by passing a narrow osteotome that divides the orthoix half of the cortical circumference first.
Product description The Orthofix LRS is a series of modular monolateral external fixators to be used in a reconstructive procedures of limb shortening, bone loss, open fractures, non union and angular deformities also for Pediatric.

Patients with severe osteoporosis, patients who are HIV positive and patients with severe, poorly controlled diabetes mellitus.
This creates a reasonable level of radial preload by the screw in the cancellous bone, and bonding will occur between it and the HA coating of the screw Fig. It has the advantage of allowing distraction and compression at fracture site.

There are many acceptable techniques and, as long as the principles are followed, regenerate formation will not be compromised. A sandwich double tier clamp on the rail is able to solve this problem. Technique Curved sagittal profile The profile of the femur in lateral ors is curved, and inserting a series of screws set in line on a straight rail is difficult Fig.
Short Stature Bone loss Open fractures Non-union Angular deformities Many years of clinical experience have confirmed the validity of the device with good outcomes for all the above indications, and defined the evolution of the surgical technique.
This study was ortnofix to assess the union rates, infection control, lengthening and the complications associated with the LRS. In our patients the outcome of bony consolidation was better than functional results. Published online Nov 4.
The Orthofix Limb Reconstruction System LRS is a series of modular monolateral external fixators to be used in reconstructive procedures for treatment of: The third screw is inserted in the third seat of the middle template—choice over which tier of the sandwich template is used for screw insertion is determined intraoperatively—the position of the screw seat that provides the most central location across the diameter of the femur is chosen Fig.
Patient was not ready for any other procedure; hence, 2 cm shoe rise was given. 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.
Single level surgery requires the use of two clamps only, whereas multilevel surgery needs at least three. This shows the box for the Paediatric LRS system.
The improved extraction torque and resistance to loosening contribute to the better hold on the individual bone segments achieved by the fixator, thereby lessening the risk of loss of control and subsequent deformity [ 6 ]. However, since we could not certainly exclude the possible future reactivation of infection, absence of discharging sinus for a minimum of 12 months was considered as success.
Turn off more accessible mode. This technical report includes tips derived from observation and experience in a busy limb reconstruction unit.
Femoral lengthening with a rail external fixator: tips and tricks
A supracondylar osteotomy with acute correction of deformity followed by lengthening corrects both problems. Patients were discharged and asked to followup at 6, 12 and 14 weeks and at completion of treatment on the OPD basis.
Several techniques of osteotomy have been described. Insert the first pin using this knee flexion technique 1. This ensures central placement of the pin across the diameter of the femur. The stability provided through the fixation device irrespective of whether this is external or internal is not static. Each surgeon must evaluate the appropriateness of a technique based on his or her personal medical credentials and experience, knowing the information reported in the Orthofix product-specific IFUs.
Order of pin ortyofix It is helpful to insert the most distal pin of the proximal clamp first Fig. Find out more and set your cookie preferences here.
Orthofkx curved sagittal profile of the femur can make it difficult to fit a straight rail. Distraction at corticotomy site was started on the seventh postoperative day. The average duration of treatment was 9. TrueLok Ring Fixation System. It is less cumbersome to the patient and more surgeon and patient friendly. Osteotomy technique There are many acceptable techniques and, as long as the principles are followed, regenerate formation will not be compromised.
Average duration of treatment was less for humerus mean 6.
