Alignment, Planning, and Logistics of Limb Deformity

Description

In this comprehensive lecture presented by Dr. Austin Fragomen, the intricacies of limb deformity analysis are explored, drawing heavily on established methodologies, particularly those developed by Dror Paley and his colleagues. The crucial premise emphasized is the necessity of accurately measuring and understanding limb deformities before any corrective interventions can be undertaken. The lecture begins with an overview of deformity analysis principles, focusing on measurements derived from radiographic images, and elucidates how normal population averages are utilized to establish benchmarks for diagnosing deformities.



Throughout the presentation, Dr. Fragomen discusses various mechanical angles essential for analyzing limb deformities, including intra- and extrathoracic measurements such as the lateral proximal femoral angle and the medial proximal tibial angle (MPTA), outlining their significance in understanding deviations from normal joint mechanics. Emphasizing the importance of a comprehensive approach to assessment, he introduces concepts such as direct and indirect leg length discrepancies, highlighting the pitfalls of relying solely on visible measurements and advocating for detailed calculations that account for potential hidden deformities.



Dr. Fragomen further engages the audience with illustrative case studies, detailing specific patients' deformities, mechanical axes, and the resulting treatment plans. He stresses critical analysis of leg length discrepancies and relationship dynamics between femoral and tibial alignment to ensure effective treatment strategies. Emphasizing the multifaceted nature of limb deformities, the lecture concludes with an acknowledgment of the complexities involved in rotational deformities and the array of surgical options available to address these issues, all while reiterating the indispensable role of detailed measurements and assessments in successful clinical outcomes.
