The Quadriceps Angle: Reliability and Accuracy in a Fox (Vulpes vulpes) Pelvic Limb Model

To evaluate the effect of measurement technique and limb positioning on quadriceps (Q) angle measurement, intra- and interobserver reliability, potential sources of error, and the effect of Q angle variation.Cadaveric radiographic study and computer modeling.Pelvic limbs from red foxes (Vulpes vulpes).Q angles were measured on hip dysplasia (HD) and whole limb (WL) view radiographs of each limb between the acetabular rim, mid-point (Q1: patellar...
