About

James D. Michelson is a leading orthopaedic researcher whose work centers on the biomechanics of the foot and ankle, with a particular focus on the flexor hallucis longus (FHL) tendon and its role in gait and pathology. His major contributions have fundamentally reshaped our understanding of hallux rigidus, a common and painful condition of the big toe. Through meticulous biomechanical studies, Michelson demonstrated that the FHL functions isometrically during normal walking, providing crucial dynamic stability to the first metatarsophalangeal joint. His landmark 2008 paper, "Contribution of the Flexor Hallucis Longus to Loading of the First Metatarsal and First Metatarsophalangeal Joint," which has garnered 60 citations, challenged prevailing clinical assumptions by revealing how restricted FHL gliding directly alters joint loading mechanics, offering a new causative framework for hallux rigidus. Complementing this, his 2008 study on "Evidence of isometric function of the flexor hallucis longus muscle in normal gait" (41 citations) provided foundational evidence for this previously unrecognized muscle behavior. Michelson’s work bridges the gap between basic science and clinical practice, offering orthopaedic surgeons and researchers a deeper, more functional understanding of foot mechanics that directly informs surgical decision-making and rehabilitation strategies.
