Frederick S. Kaplan, the Isaac and Rose Nassau Professor of Orthopaedic Molecular Medicine in Orthopaedic Surgery at the Perelman School of Medicine, has been awarded the Grand Hamdan International Award on Musculoskeletal Disorders. The honor notes that his “investigations of the rare diseases Fibrodysplasia ossificans progressiva (FOP) and Progressive osseous heteroplasia (POH) have uncovered mechanisms so pathogenically fundamental to tissue metamorphosis that they have challenged existing dogma far outside the usual realm of musculoskeletal medicine.” Dr. Kaplan was honored in a ceremony held in Dubai, United Arab Emirates, in December.
