Jones Fractures
A Jones fracture is a break in the fifth metatarsal; the long bone located along the outside of the foot that connects to the little toe. The fifth metatarsal plays an important role in balance, stability, and movement. Every time you stand, walk, run, or change direction, this bone helps support and distribute weight across the foot. Because it is exposed to significant forces during everyday activities, it can be vulnerable to injury.
Jones fractures are frequently seen in athletes who participate in sports involving running, jumping, cutting, and rapid changes in direction. However, they are not limited to athletes. Anyone can experience this injury, including people who are walking on uneven ground, stepping awkwardly off a curb, or participating in routine recreational activities.
A Jones fracture is often slower to heal because it occurs in a portion of the fifth metatarsal that has a relatively limited blood supply compared to other areas of the bone.
Blood delivers oxygen, nutrients, and healing cells to injured tissues. When a fracture occurs in an area with less blood flow, the body’s ability to repair the bone can be less efficient, which may prolong healing.
- Sharp pain is usually the first and most noticeable symptom of a Jones fracture. The discomfort is typically felt along the outside of the foot near the base of the little toe. Some individuals describe hearing or feeling a pop at the time of injury.
- Swelling commonly develops around the fracture site. The outer side of the foot may become swollen within hours of the injury and remain swollen for several days. In some cases, the swelling may extend into nearby areas of the foot.
- Bruising is another common symptom. Blood from the injured tissues may collect beneath the skin, causing discoloration that can appear blue, purple, or dark red. Bruising may become more noticeable over the first few days following the injury.
- Difficulty placing weight on the foot.
Jones fractures are generally classified as either acute fractures or stress fractures. An acute Jones fracture occurs suddenly after an injury such as twisting the foot, rolling the ankle, or landing awkwardly. A stress Jones fracture develops gradually from repetitive loading of the foot over time and is commonly seen in runners and athletes who participate in high-impact sports.
- Acute Jones fractures often involve sports where running, jumping, pivoting, and sudden changes in direction place repeated stress on the outer portion of the foot. Basketball, soccer, football, tennis, volleyball, and track and field athletes are among those most commonly affected. Falls can also cause a Jones fracture. Landing awkwardly after a jump or stepping incorrectly onto an uneven surface may place enough force on the bone to cause it to break.
- Stress Jones fractures can be caused by repetitive stress that gradually weakens the bone over time. Each impact creates tiny areas of damage that the body normally repairs. However, when stress is applied faster than the bone can recover, these small injuries can accumulate and eventually lead to a fracture. This type of stress-related injury is often seen in runners, military recruits, dancers, and individuals who participate in frequent high-impact activities. It can also occur in older people with osteoporosis or osteopenia (low bone density).
Certain foot structures may also increase the risk of developing a Jones fracture. People with high arches often place more pressure along the outside of the foot, increasing stress on the fifth metatarsal. Similarly, some individuals naturally walk or run in a way that places greater force on the outer edge of the foot.
Sudden increases in training intensity, duration, or frequency can also contribute to the development of stress fractures. This is particularly common among athletes who rapidly increase their activity levels without allowing adequate time for recovery.
An osteoporotic Jones fracture on the other hand can occur with little provocation at all.
Diagnosis begins with a detailed discussion of your symptoms and medical history. Your orthopedic specialist will ask when the pain began, whether there was a specific injury, and what activities make the symptoms worse.
Understanding how the injury occurred can provide important clues. A sudden onset of pain following a twisting injury may suggest an acute fracture, while gradually worsening discomfort may indicate a stress-related injury.
Your Orthopedic Associate will perform a physical exam to evaluate the foot for swelling, bruising, tenderness, and areas of localized pain on the outer side of the foot where Jones fractures occur.
Your ability to stand, walk, and bear weight will also be assessed. The physician may examine the overall alignment of the foot and ankle and evaluate nearby structures to rule out other potential causes of pain.
Imaging studies are typically needed to confirm the diagnosis. X-rays are usually the first test performed and can often clearly show the location and severity of the fracture.
In some cases, particularly when a stress fracture is in its early stages, the injury may not be immediately visible on X-rays. If symptoms strongly suggest a Jones fracture despite normal X-ray findings, additional imaging may be recommended.
Magnetic resonance imaging (MRI) can detect subtle stress injuries and provide detailed images of both bone and surrounding soft tissues. Computed tomography (CT) scans may also be used to provide a more detailed view of the fracture and evaluate the extent of the injury.
Accurate diagnosis is important because several different types of fractures can occur in the fifth metatarsal. Determining the precise location of the break helps distinguish a Jones fracture from other injuries affecting the outer side of the foot.
If you are experiencing persistent foot pain, swelling, tenderness, or difficulty walking after an injury, the orthopedic specialists at Orthopedic Associates of Northern California in Chico can provide a thorough evaluation and accurate diagnosis to help determine the cause of your symptoms.
