The difficulty and delayed healing has lead most surgeons to perform surgery on the bone and fixate it with hardware. Unfortunately, these fractures don’t usually heal quickly. These people must pay close attention to the amount of high-level activity that they perform and wear shoes designed to support and dissipate stress within their feet. These new studies indicate that a person that with a cavus foot or a “high arch” is more susceptible to these fractures. Previously, the use of force mats or plates were not able to capture the true nature of the mechanics of the foot during high level activity.
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. Foot fractures often end the season for many athletes and improperly treated fractures have even ended careers.
