This 37 year lady came to us with complain of pain while walking and hard swelling in her left heel area. On examination a callus on her left heel diagnosed. Surgical excision planned under local anaesthesia. For better dissection, Blade No -- 11 is used. At the junction of callus and normal tissue which can be felt clearly by palpation, the knife is introduced in an oblique fashion. While dissecting one can feel by the smooth movement of knife edge at the edge of callus. After complete removal watch the callus, its shape and the cavity to ensure complete removal . Just scrape the edge of the cavity to make it smoother for better healing. Pressure dressing is necessary and rest to the part for one day. With proper dressing and wound care this wound heals in a span of 7 to 10 days.
