The Labyrinth of Foot and Ankle Biomechanics: Pathologic Interactions between Kinematics and Morphology
Abstract: The foot and ankle is a complex structure of numerous articular relationships which operate to provide a stable base of support through active and passive tissue interactions. Altered morphology can lead to injury, instability, pathological deformity, and osteoarthritis. My lab’s goal is to characterize healthy, diseased, and post-surgical foot and ankle morphology and in-vivo function to improve clinical treatment of ankle pathologies leading to end-stage ankle osteoarthritis. Our recent studies have investigated the subtalar joint in patients that received a tibiotalar arthrodesis or total ankle replacement (TAR) surgery and found that subtalar joint kinematics are altered after tibiotalar arthrodesis, but we found minimal compensations in the motion of the subtalar joint of patients who had underwent TAR. Dynamic joint articulation measurements, such as joint space distance, coverage, and congruence can be investigated in combination with morphology analyses using statistical shape modeling to investigate the form and function relationship occurring at the subtalar joint following surgical intervention. Our ongoing studies highlight the complexity of the foot and ankle, the value of a robust 3D analyses, and the necessity to further investigate interactions of function and morphology to clinically evaluate flatfoot deformity, osteoarthritis, and injury mechanisms.
Biography: Dr. Amy Lenz studies foot and ankle orthopaedic biomechanics with a focus on characterizing healthy, diseased, and post-surgical foot and ankle morphology and in-vivo function to improve clinical treatment of ankle pathologies. Her expertise is in medical imaging, human biomechanics, and statistical shape modeling to integrate experimental and computational research to define relationships between 3D anatomy and dynamic movement.
