Research was performed to assess the accuracy of plain film radiography in measuring translation of the talus during the anterior drawer (AD) test and the rotation of the talus during talar tilt (TT) stress testing, as well as to further define instability in the sagittal, coronal, and transverse planes. Twenty lower extremity specimens were positioned in a Telos ankle stress apparatus, and respective lateral and AP radiographs were taken during simulated AD and TT testing. Positional measurements were estimated from the films, and then a three-dimensional (3D) tracking system was employed to calculate these displacements. The anterior talofibular ligament and calcaneofibular ligament were sectioned to simulate an unstable ankle, followed by repeat measurement using both techniques. Movement calculated using the 3D system was compared to that of plain radiographs using a paired t-test. The average positional changes ascertained by plain film radiographs were found to be substantially lower than those measured by the 3D system in both AD and TT tests in the intact and sectioned states.

About drphilipw
Dr. Philip Wrotslavsky specializes in the diagnosis and treatment of infant, children and adult patients with medical conditions of the foot, ankle and lower leg structures.
Dr Wrotslavsky completed his orthopedic fellowship (Chief Fellow) at The Limb Reconstruction Fellowship Program at the International Center for Limb Lengthening in Baltimore, Maryland under the guidance of Dr. Dror Paley and Dr. John Herzenberg. His fellowship experience included the in-depth study, prevention, and treatment of limb threatening foot conditions, infections, diabetic charcot neuroarthropathy, nonunions, malunions, and congenital and posttraumatic limb deformities. He has adopted techniques derived from the science of distraction osteogenesis.He is adept at utilizing the full gamut of orthopedic fixation materials, including screws, wires, plates, intramedullary rods, and monolateral and circular fixators (Ilizarov and Taylor Spatial Frame) in the treatment and correction of deformities.
His 4 years of podiatry foot and ankle surgical residency training took place in an inner city hospital in New York City, where he worked with a multidisciplinary team of general, podiatric, orthopedic and vascular physicians and surgeons and provided a wide variety of foot and ankle care including wound care, ankle arthroscopy, diabetic limb salvage and reconstruction, flatfoot reconstruction, neurological cavo-varus foot reconstruction and management of trauma to the foot and ankle.
Dr Wrotslavsky's fellowship and residency training has taught him to perform a full biomechanical exam identifying lower extremity pathology from spine to foot.He enjoys working with a team of physicians identifying the patients’ pathology and providing the appropriate treatment.
