* Accuracy Statement for devices with a measuring function:
Devices with a measuring function are considered non-critical, non-calibrated, and are intended for reference-only measurements. While it provides a helpful visual guide for relative measurements, it is not calibrated to specific precision standards. Measurements taken with this device should not be considered accurate enough for critical applications requiring strict dimensional tolerances. General manufacturing tolerances of +\- 1% at each graduation, or 2% of the full scale apply, but no conformance qualifications are provided or implied.

Utilizes a 5/32" (4 mm) threaded pin (dull on the outer end) in the iliac crest and a 1/8" (3,2 mm) pin in the greater trochanter. (The soft tissue is cleared away and a single drill hole is drilled in the trochanter to accommodate the distal pin, and the hole is marked with methyline blue so it can be easily found.)
Alternatively, a 7.3 mm cannulated screw that accepts a 3.2 mm pin may be used in the greater trochanter. Using the sliding caliper, the difference in leg length measurement before hip dislocation and after the THR procedure helps show the change in leg length.

Used intra-operatively to help determine the vertical distance of offset (if any) between the rotational center of the femoral head and the top of the greater trochanter. The measurement can then be used for verification, after femoral stem and head implantation but before final fixation, to help determine what adjustments (if any) are necessary to equalize the pre- and post-operative rotational center-trochanteric offset.

The flexible, adjustable arm can help reduce patient (and technologist) embarrassment or discomfort when it is required to be positioned in a sensitive area such as the inner thigh.
Fully positionable, this orthopedic X-Ray calibration and marking device features a 1" (25.4mm) stainless steel ball which, when properly positioned at bone level on a precise anatomical plane, will be this exact size when viewed from all angles, allowing it be used as a calibration marker in surgical planning software applications, helping to gauge the size of other components on that plane. This helps establish precise anatomical measurement.
