Before I go further on bunions, there is another deformity that is often related to and can be found in conjunction with hallux abducto valgus.
This deformity has many different names, including tailor's bunion, bunionette, bunion on the little toe and pinky toe.
The term tailor's bunion came about due to tailors sitting crossed legged to sew in ancient times, causing a bump on the small toe side of the foot. In effect, this deformity is a mirror image of the bunion on the big toe.
Similar to Hallux valgus, where the big toe deviates toward the second toe, in a tailor's bunion the fifth toe moves toward the fourth toe. In many cases, there are bunions on both sides of the foot as the same forces that cause bunions also cause tailor's bunions. The result is a very wide splay foot with the big toe and small toe deviated toward the middle of the foot. This type of foot has major issues fitting shoes.
