![]() ![]() Walking, running, jumping and agility type “cutting” can now be studied. Recent studies using wireless, pressure sensor insoles has enabled healthcare professionals and researchers to study the amount of pressure applied to the different parts of the foot during high level activity. The occurrence and type of Jones fracture corresponds with body weight and activity level. ![]() Lastly, a fracture in the shaft or zone 3 can take a very long time to heal and is frequently treated by performing surgery. The fracture that occurs at the junction of the base and the shaft it is in zone 2 and it might be fixed surgically. The first zone is a “chip” or avulsion fracture and treated conservatively in a cast or boot. The fractures are described by the area that they occur and it is one of three zones of the metatarsal. The muscles strong contracting force to help stabilize the foot / ankle from the lateral side can increase the pressure applied to the base of the bone. The bone accepts most of the body’s weight during gait and the Peroneus Brevis muscle inserts to that part of the metatarsal. The compression and sheer forces that are placed on that part of the bone are enormous in some people and body weight and activity level can pre-dispose them to the Jones Fracture. The fracture is thought to occur secondary to the accumulation of stress and pressure that is placed on that part of the 5 th metatarsal. He was the first to describe the fracture in the foot that occurs in the base of the 5 th metatarsal bone on the lateral aspect of the foot. The Jones Fracture is named after a British Orthopaedic surgeon, Sir Robert Jones. Other times the injury is so severe that it will require surgery. Rehabilitation seeks to restore normal foot mechanics, strengthen the core and lower extremity musculature and implement the use of a device that will help to “unload” that part of the foot. ![]() Sometimes the Jones Fracture can be treated through rest and rehabilitation. Several popular athletes have been sidelined due to a foot injury known as the Jones Fracture. You shouldn’t continue to exercise if you suspect that you have fractured your fifth metatarsal.Foot fractures often end the season for many athletes and improperly treated fractures have even ended careers. What shouldn’t I do if I have a fractured fifth metatarsal? The RICE regime should also be commenced. You should go to your nearest accident and emergency department as soon as possible. If you have or suspect you have a fracture of the fifth metatarsal bone you should not continue to perform activity on the foot. What should I do if I have a fractured fifth metatarsal? The acute spiral fracture of the distal third is seen especially in dancers who suffer this fracture if they lose their balance while on their toes (demi pointe) and roll over the outside border of the foot.The Jones’ fracture may be the result of the foot rolls inwards whilst the toes are pointed downwards) or, more commonly, as a result of overuse.The fracture of the tuberosity at the base of the fifth metatarsal is usually an avulsion injury (where the tendon pulls off a small piece of bone) that results from an acutely sprained ankle.How does a fracture of the fifth metatarsal happen?
