The term 'THIN, AS A FRACTURE' can be described as a 'HAIRLINE' which is an 8 letter word. A HAIRLINE fracture is a type of fracture that occurs in thin bones such as those found in the hands and feet. It is a very small break in the bone that is usually caused by repetitive stress or trauma. The fracture is so small that it may not be visible on an X-ray. Symptoms of a HAIRLINE fracture include pain, swelling, and tenderness in the affected area. Treatment typically involves rest, ice, and elevation of the affected area.
