We have developed a non-invasive measurement technique which can ultimately be used to quantify three-dimensional patellar kinematics of human subjects for a range of static positions of loaded flexion and assessed its accuracy. Knee models obtained by segmenting and reconstructing one high-resolution scan of the knee were registered to bone outlines(More)
Accuracies of a point-based and an intensity-based fluoroscopic methods of assessing patella tracking were determined by comparing the pattern of patellar motion with respect to orientation (flexion, internal rotation, and lateral tilt) and translation (lateral, proximal, and anterior) with the pattern of patellar motion measured using Roentgen(More)
Michel's anomaly is an extremely rare cause of congenital sensorineural hearing loss. We present a 2-1/2 year old white female with this inner ear defect associated with type I microtia and microdontia. Assessment of anatomic structures of the ear is critical in an infant with abnormal auditory brainstem responses to determine whether a structural lesion is(More)
Accuracy of a novel fluoroscopy-based method of assessing patellar tracking was determined by comparing the pattern of patel-lar motion with respect to orientation (flexion, internal rotation, and lateral tilt) and translation (lateral, proximal, and anterior) with the pattern of patellar motion measured using Roentgen Stereophotogram-metric Analysis (RSA)(More)
