Firstly some definitions for you all. More on treatment etc soon:

Definition: A Jones fracture is an injury to the fifth metatarsal bone of the foot. The fifth metatarsal bone is at the base of the small toe, and the Jones fracture occurs in the midfoot area (the top of the bone).

Why is this called a "Jones Fracture"?

This injury was first described in 1902 by Sir Robert Jones in an article titled "Fractures of the Base of the First Metatarsal Bone by Indirect Violence." He included descriptions of six patients (one being himself) who sustained fractures in this area without a direct impact (his injury occurred while dancing). This article included fractures we now classify as avulsion fractures, stress fractures, and what we presently refer to as a Jones fracture.

What are the symptoms of a Jones fracture?

Patients who sustain a Jones fracture have pain over this middle/outside area of their foot, swelling, and difficulty walking. Most often a Jones fracture is caused without significant injury or impact.
