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.

Patients with foreign body sensitivity where material sensitivity is suspected, tests should be made prior to implanting. Technique Order of pin insertion The same technique for locating the maximal width of the ortofix before drilling across is used. The incision is either longitudinal or transverse and the fascial incision likewise.

Complications were classified according to Paley classification as problem, obstacle or true complication. Order of pin insertion 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. Pin tract infection resolved with regular dressing before removal of frame. Clin Orthop Relat Res. The union occurred in Consequently, regenerate formation is usually good, provided the general principles of osteotomy are followed.

Soft tissues tend to prefer a slower rate of distraction and may be at risk of increased fibrosis if distracted at a faster rate [ 10 — 12 ]. Other two cases were infected nonunion of femur. TrueLok Ring Fixation System. Disadvantages Varus and procurvatum control Gradual development of varus and procurvatum occurs with proximal femoral lengthening, irrespective of the type of external fixator device used.

Bone lengthening, Femur, External fixator. Age related changes in lymphocyte development and function.

Final results of our study is shown in [ Table 4 ]. Out of 30 cases, 28 were males with a mean age of Limb lengthening by callus distraction callotasis J Pediatr Orthop. Chapter 8, Rockwood and Green’s fracture in adults.

Only when the drill, drill and screw guides are passed down orthlfix bone and held, is the knee extended then and placed on the operating table. Published online Nov 4. Expert Rev Med Devices. The higher peak forces and accompanying muscle tension generated by bifocal lengthening produce greater pain.

The Orthofix Limb Reconstruction System LRS is a series of modular monolateral external fixators to be used in reconstructive procedures for treatment of: It is helpful to insert the most distal pin of the proximal clamp first Fig. Linton PJ, Dorshkind K.

The straight clamp templates have been assembled on the rail. Active and passive mobilization of adjacent joint was encouraged the day following operation.

Femoral lengthening with a rail external fixator: tips and tricks

Each pin should be inserted across the diameter of the bone and avoid eccentric intracortical insertion. Confirmation of completion of the osteotomy is through the manipulation of the two segments and by X-ray.

Limb Reconstruction is the discipline which attempts to correct anatomy and restore function in a deformed or deficient limb. This is to avoid deformity that may occur when a greater amount of lengthening is attempted from a single site.

Muscle releases are usually necessary for this group of conditions. Start by marking out the location of the proposed osteotomy. Support Materials Support Materials.

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. This ensures that the lateral aspect of quadriceps including the iliotibial tract is transfixed in flexion Fig.

The osteotomy is low energy and preserves the soft tissue envelope and vascularity. It is inevitable that some movement ors lost, albeit temporarily, during the period of lengthening.
