SMR 100'S MODULAR HIP STEM VASTAGO MODULAR DE CADERA The SMR 1OO’S stem is a modular system designed for hip replacement in cases of dysplasia, results of fractures and osteotomies. The stem features three components: proximal component, distal component and locking screw. The proximal component is available in sizes from 4Omm to 7Omm, The distal component is 1OOmm long. El vástago SMR 1OO’S es un sistema modular concebido para el recambio protésico de cadera en los casos de displasia, resultados de fracturas y osteotomías. El implante femoral consta de tres elementos: un componente...

PROXIMAL COMPONENT The modular proximal component solves the problem of restoring the physiological length of the limb and stabilizing the joint thanks to its four lengths 40, 50, 60 and 70mm and two CCD angles 125° and 135°. The mirror polished neck area has been studied to decrease polyethylene wear during flexion. In addition, the mirror finish eliminates the risk of fatigue cracks. El componente proximal modular consigue resolver el problema de la restauración fisiológica de la longitud y estabilidad de la articulación gracias a las quatro longitudes 40, 50, 60 y 70mm y los dos ángulos...

SMR 100'S MODULAR HIP STEM VASTAGO MODULAR DE CADERA Pre-operative assessment Thorough pre-operative planning enables the surgeon to adopt a correct approach to the operation and foresee certain situations that might arise. The objective is to choose the diameter and length of the distal component and size of the proximal component. Pre-operative choice of components is indicative, as the definitive size will be determined intra-operatively. Pre-operative planning requires an anterior-posterior X-ray of the pelvis and pre-operative templates of the SMR 100's stem (provided in the instrument...

Reaming of distal component Escariado componente distal EN Having completed the removal of the previous implant, proceed to reaming with the conical reamers (Ref. 120540714 ÷ 120540724*). (FIG.2) Reaming may be done manually with the “T” handle (Ref. 110381521) or with a motor, using the Jacobs Adaptor (Ref. 110381525). The instrument kit has reamers with diameters from 14 mm to 20 mm, in 1 mm steps, and 22 mm and 24 mm. Start with a reamer that’s one or two millimetres smaller than the measurement taken in pre-operative planning. The reamers must be inserted into the femoral canal till the...

SMR 100'S MODULAR HIP STEM VASTAGO MODULAR DE CADERA Insertion of distal component Inserción componente distal ES Use of the reamers yields information on the diameter and correct depth of the distal component in the cortical. Mount the distal component inserter (Ref. 120540410) on the chosen component (Ref. 120373914 ÷ 120373924*) and proceed to feed it into the previously prepared canal. Proceed to insertion with the distal component inserter advancing gradually and checking the depth, as far as the maximum, to obtain good torsional stability and avoiding any unexpected penetration under...

Preparation of the bone for the proximal component Preparación del hueso para el componente proximal EN Remove the distal component inserter (Ref. 120540410) from the distal component, screw the guide shaft for tubular reamer (Ref. 120540415) onto the distal component. (FIG.4a) When carrying out this operation, make sure it’s done in the right direction, as a mistake could irreparably damage the distal component and compromise all the successive phases. Now ream the proximal portion with the appropriate tubular reamer (Ref. 120540400) to prepare a housing for the proximal component....

SMR 100'S MODULAR HIP STEM VASTAGO MODULAR DE CADERA Insertion of trial proximal component Inserción componente proximal de prueba ES Insert the trial proximal component and lock it with the appropriate screw (Ref. 120540040 ÷ 120540070). Do not tighten excessively. (FIG.5a) Introducir el componente proximal de prueba, apretándolo con el tornillo adecuado (Ref. 120540040 ÷ 120540070). No apretar excesivamente. (FIG.5a) Trial reduction Mount the trial head (Ref. 110380860 ÷ 110380890, 110380960÷110380990, 110381060÷110381090) on the taper of the trial proximal component (Ref.120540140 ÷...

Insertion of the definitive proximal component Insertion of the definitive proximal component EN Remove the trial head and trial proximal component using the revision proximal component extractor (Ref. 120540420). Proceed with prudence in the extraction phase and make sure the correct direction is chosen, as a mistake could compromise all the successive phases. Take the definitive proximal component (having the same size as the trial one; Ref. 120362540 ÷ 120362570; 120363540 ÷ 120363570) and use the revision proximal component impactor (Ref. 120540411) to insert it in the Morse taper of...

SMR 100'S MODULAR HIP STEM VASTAGO MODULAR DE CADERA Blocking the proximal component Bloqueo del componente proximal ES Insert the locking screw (Ref. 120376140 ÷ 120376170) of the appropriate size for the proximal component used and tighten it with the screwdriver for revision/resection prosthesis (Ref. 120540405). When tightening the screw, use the non-rotation device (Ref. 120540412), which fits into the Morse taper, to prevent rotation during assembly. (FIG.7) The locking screw ensures additional anchoring between the distal and proximal components, as well as holding the Morse taper....

Extraction of SMR 100's proximal component Extracción componente proximal SMR 100's EN Should it be necessary to extract the proximal component of the SMR 100's stem, remove the locking screw, screw the extractor for revision proximal component (Ref. 120540420) into the locking screw hole and turn until it’s fully extracted. (FIG.8) En el caso de que sea necesario extraer el componente proximal del vástago SMR 100's extraer el tornillo de bloqueo, atornillar el extractor para componente proximal de révision (Ref. 120540420) en el agujero del tornillo de bloqueo y girar hasta haber...
