What is a Tailor’s Bunion?
Tailor’s bunion, also called a bunionette, is a prominence of the fifth metatarsal bone at the base of the little toe. The metatarsals are the five long bones of the foot. The prominence that characterizes a tailor’s bunion occurs at the metatarsal head, located at the far end of the bone where it meets the toe. Tailor’s bunions are not as common as bunions, which occur on the inside of the foot, but they are similar in symptoms and causes.
Why is it called a tailor’s bunion? The deformity received its name centuries ago, when tailors sat cross-legged all day with the outside edge of their feet rubbing on the ground. This constant rubbing led to a painful bump at the base of the little toe, or tailor’s bunion pain.
Causes of Tailor's Bunion (Bunionette)
Often a tailor’s bunion is caused by an inherited faulty mechanical structure of the foot. In these cases, changes occur in the foot’s bony framework, resulting in the development of an enlargement. The fifth metatarsal bone starts to protrude outward, while the little toe moves inward. This shift creates a bump on the outside of the foot that becomes irritated whenever a shoe presses against it.
Sometimes a tailor’s bunion is actually a bony spur (an outgrowth of bone) on the side of the fifth metatarsal head.
Regardless of the cause, the symptoms of a tailor’s bunion are usually aggravated by wearing shoes that are too narrow in the toe, producing constant rubbing and pressure.
Symptoms of Tailor's Bunion (Bunionette)
The symptoms of tailor’s bunions include redness, swelling and pain at the site of the enlargement. These symptoms occur when wearing shoes that rub against the enlargement, irritating the soft tissues underneath the skin and producing inflammation.
Diagnosis of Tailor's Bunion (Bunionette)
Tailor’s bunion is easily diagnosed because the protrusion is visually apparent. X-rays may be ordered to help the foot and ankle surgeon determine the cause and extent of the deformity.
