Metatarsalgia, Calluses, and Callosities of the Feet
In this chapter, anatomic and biomechanical features of the foot were described in detail, as well as the clinical characteristics of metatarsalgia, calluses, and plantar callosities, with their respective causes. The differential diagnoses of plantar cutaneous lesions and the most appropriate therapeutic procedures to the main diseases are outlined. In addition, orthopedic deformities of the toes and their skin consequences are described. Many illustrations are included to complement and help explain the different aspects of the diseases discussed.

A bony bump that forms on the joint at the base of the big toe. A bunion forms when the big toe pushes against the next toe, forcing the joint of the big toe to get bigger and stick out.
Inflammation and swelling of a bursa. A bursa is a fluid-filled sac which forms under the skin, usually over the joints, and acts as a cushion between the tendons and bones.
Excision of a condyle. Plantar condylectomy has been presented as a procedure indicated in the correction of dislocated metatarsophalangeal joints.
A benign adnexal neoplasm composed of epithelial cells that show tubular (usually distal ductal) differentiation, derived from sweat glands.
Any skin disorder consisting of a growth that appears horny.
Bony projections that form along joint margins, commonly referred to as bone spurs.
A surgical operation whereby a bone is cut to shorten or lengthen it or to change its alignment.
A sensation of tingling, tickling, pricking, or burning of a person’s skin with no apparent physical cause.
Inflammation of a synovial (joint-lining) membrane, usually painful, particularly on motion, and characterized by swelling, due to effusion (fluid collection) in a synovial sac.
