7 TRAUMA IMPLANTS & INSTRUMENTSOrthopaedic RulerRuler with Radio Opaque 1.0mm scaleImperialUsed to measure Pin, Wire, Drill and Screw diameter.ORTHOPAEDIC RULER001498 Orthopaedic Ruler Imperial 150mm £26.50001496 Screw and Drill Gauge 60mm £19.50VI Metric RulerFollowing requests, our Metric Ruler has been over-hauled to provide agreater range of hole sizes, making it the most comprehensive Metric Rulerwe have seen on the market.Hole sizes - 0.9, 1.0, 1.1, 1.25, 1.4, 1.5, 1.6, 1.8, 2.0, 2.5, 2.7, 3.0, 3.2, 3.5,4.0, 4.5, 5.0, 5.5 and 6.5mm.VI METRIC RULER001504 Metric Ruler - VI. 150mm £36.50Xray Marker with ScaleUsing digital media regardlessof whether the xray was takenon an analogue or digital xraymachine it is very important toincorporate a reliable scale.When viewed on differentscreens an xray may appear tobe a different size. This isparticularly important when the original is not available for comparison.When sending digital radiographs to colleagues for opinion a scale isespecially important. VI’s Left and Right Markers are 50mm long andinclude a scale marked at 5mm intervals. For use when measuringparticular structures or lesions the marker should be positioned at thesame level as the structure under examination. A purpose designed standis available which incorporates a clip to hold the appropriate marker.XRAY MARKERS WITH SCALEXRAYMARK1 Xray Marker with Scale. Left and Right £6.75XRAYHOLD1 Xray Marker Stand £37.50While digital radiography has huge benefits it can be difficult to scaleimages. The problem is compounded when prints aremade for viewing by a third party. e.g. BVA/ KCElbow Dysplasia Scheme where accuratemeasurements down to 2mm are veryimportant. The new Ruler is 120mm long andgraduated in 1.0mm increments. Placed at thelevel of the bone or joint under investigation atthe time of radiography it will enable accuratescaling of lesions. Also available in 500mmlength. Reduced visibility over 70 kV 16mAs.RADIO OPAQUE RULERTaking radiographswhere the area ofinterest is not close tothe platecreates somechallenges in scaling.This is true of bothdigital andanalogue systems.When using theradiograph fortemplating implantse.g. total hipreplacement it is very important to make accurate measurements.The Reference Ball is 25mm in diameter and is attached to a stable baseby a flexible neck which allows the Ball to be placed at the same levelabove the plate as the area of interest. Using a spherical object as areference eliminates errors created by ruler type reference which mightnot be quite parallel with the plate.X-ray from Alex Li001495 Radio Opaque Ruler 120mm £36.50Radiographic Reference BallAlso available in a 10mm version for smaller patients.RADIOGRAPHIC REFERENCE BALLXRAY25MM Radiographic Reference Ball 25mm diameter £72.50XRAY10MM Radiographic Reference Ball 10mm diameter £77.50Chandler’s Gonadal ShieldCHANDLER’S GONADAL SHIELDExposure of the patient’sgonads to radiation isundesirable particularly whererepeated imaging is likely.The Gonadal Shield uses asimilar ‘goose neck’arrangement on a solid baseas is used in the referenceball.
