Dr. Luis Hermida is an orthopedic surgeon who specializes exclusively in feet and ankles—nothing else.
Marta Debayle introduces Dr. Luis Hermida, an orthopedic surgeon who focuses solely on feet and ankles, trained in Argentina, Spain, and the United States. The episode begins with a poll asking listeners about their experiences with bunions and calluses. Dr. Hermida explains that bunions are a bony protrusion at the base of the big toe, primarily caused by genetics, with women over 50 being more susceptible. He clarifies that high heels do not cause bunions but can exacerbate existing ones. The discussion addresses common misconceptions, such as the ineffectiveness of bunion correctors and toe separators. Surgery is recommended only when bunions cause pain or limit daily activities, not for aesthetic reasons. Marta shares her personal comfort with high heels, and Dr. Hermida explains this is due to muscle and tendon adaptation. The conversation shifts to calluses, describing them as the skin's response to friction or pressure, with causes including foot architecture, viral infections like plantar warts, and improper footwear. Dr. Hermida advises against self-treatment with chemical patches and recommends professional care. They also cover topics like hammertoes, foot development in children, and the importance of proper shoe width and depth. Listener questions are addressed, including issues like plantar fasciitis, flat feet, and foot care for athletes. Dr. Hermida emphasizes genetic factors in conditions like flat feet and discusses the role of orthotics. The episode concludes with contact information for Dr. Hermida and plans for future guests on podiatry and gait analysis.
