Product Overview
Designed to help measure and evaluate pre- and post-THR leg length in conjunction with X-ray calibration and clinical judgement
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 accomodate 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.
