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.

Attach the rail and two templates, seating this screw in the most distal position of the proximal clamp. Use of Ilizarov technique for treatment of nonunion of tibia associated with infection. Patients with severe osteoporosis, patients who are HIV positive and patients with severe, poorly controlled diabetes mellitus.
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. Bifocal femoral lengthening Advantages Shorter healing time The bone healing index the period for which external fixation is required divided by total gain in length—expressed as days per cm is not a constant figure.
Pain The higher peak forces and accompanying muscle tension generated by bifocal lengthening produce greater pain. 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.
The usual chosen sites of femoral osteotomy for lengthening are metaphyseal regions, often the subtrochanteric or supracondylar areas.
Osteotomy technique There are many acceptable techniques and, as long as the principles are followed, regenerate formation otrhofix not be compromised. Stefan Burkart leaves Entscheiderfabrik The last day of the fair at this year’s Medica was also the last J Orthofis Joint Surg Am. The most important disadvantage of distal femoral lengthening is interference with knee movement range.
Management of complex long bone nonunions using limb reconstruction system
Patil S, Montgomery R. Sites for lengthening The usual chosen sites of femoral osteotomy for lengthening are metaphyseal regions, often the subtrochanteric or supracondylar areas. Please enable scripts and reload this page. It is important to note orthofiz the most proximal screw of the proximal clamp is likely to be at a level where the second cortex for the screw will be across the femoral neck; perforating the femoral neck with a screw may leave the patient at risk of a femoral neck fracture after fixator removal.
De Bastiani G, et al. Turn off more accessible mode.
Average lengthening achieved was 4. Problems, Obstacles and complications of limb lengthening by the Ilizarov technique. This area in the proximal femur has an excellent blood supply from anastomoses between branches of the medial and lateral circumflex femoral vessels.
Chapter 8, Rockwood and Green’s orthofux in adults. Lower Extremity Product Gallery. This study was conducted to assess the union rates, infection control, lengthening and the complications associated with the LRS.
The co-operation of the physical therapist and patient is also important, since the patient must exercise the limb and joints.

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 ]. Active and passive mobilization of adjacent joint was encouraged the day following operation.
This case finally underwent for below knee amputation. Mean residual limb length discrepancy was 1. Short stature Bone loss Open fractures Non-union Angu lar deformities 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.
To lengthen this short tibia a metaphyseal osteotomy has been made between the clamps middle pictureand when callus begins to form, the distal clamp is moved down the rail, stretching the callus and lengthening the bone by the required amount.
Femoral lengthening with a rail external fixator: tips and tricks
After the skin and fascia orthofox and blunt dissection to the near cortex, the drill tip sheathed in the screw and drill guides that act as the soft tissue guard can be used as a trocar tip to determine the anterior and posterior limits of the femoral width.
The influence of sex hormone on coagulation and inflammation in the trauma patients.
Usually, this is only possible when the degree of curvature is small and the femur large. Using the drill tip in its drill and screw guides, locate the central part of the femur and drill across at right angles to the axis of the femur.
Patient should be involved in daily adjustment of the apparatus. Pin placement across the diameter of the femur maximises the hold of that segment. Short stature Bone loss Open fractures Non-union Ortjofix lar deformities 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 orthofxi technique.
They present with indolent infection, which is almost always associated with deformity, limb length discrepancy, joint stiffness, disuse osteoporosis and soft tissue atrophy.
The infection appeared to have been eradicated in most of our patients In the absence of this problem, femoral lengthening can be performed along the anatomical axis. When both reference pins are securely orhofix in their respective screw guides in the proximal and distal clamp templates, insertion of the remaining screws is a mechanical process as the position of the rail against the femur would have been determined by first two reference screws.
