The diagnosis is made with general, diagnostic x-rays consisting of three views: AP or anteroposterior view, oblique view, and lateral view. These should be made with the foot in full flexion.
In the case of acute fracture in an athlete, a single screw with or without bone graft can be placed into the 5th metatarsal through the proximal end. Per doctor preference and the size of the metatarsal anything from a 4.5mm to 6.5mm, cannulated or solid screw can be used. The length of the screw also varies depending on where the fracture is and again how long the metatarsal is. Even after the screw is inserted some nonunions may still occur in which case a bone graft is done, the graft usually coming from the hip, or the distal tibia.
A Jones fracture often does not heal for several reasons. This location is an area of poor blood supply. In medical terms it is a watershed area between two blood supplies. In addition there are various tendons attaching in the area pulling the fracture apart causing motion at the site of healing.
This is also called a Pseudo-Jones fracture.
Dancer's fracture is a fracture caused by a tendon pulling off a small portion of bone. There are two small muscles on the end of this bone, one of the main causes of the bone piece not rejoining; non-union or delayed union is common. Other treatments commonly encouraged are increased intake of vitamin C and calcium.
These fractures are not as severe as a Jones fracture.
