Fractures of the Base of the Fifth Metatarsal Bone: A Critical Analysis Review.

»: Fractures of the proximal fifth metatarsal (PFMT) are one of the most common foot injuries, accounting for 61% to 78% of all foot fractures, but full consensus on their classification, diagnosis, and treatment has not yet been reached.

»: The most commonly accepted classification is that of Lawrence and Botte, who divided the location of PFMT fractures into 3 zones with respect to their healing potential.

»: Avulsion fractures of the tuberosity of the base (zone 1) generally heal well, and nonoperative treatment is commonly recommended.
