Toe and Metatarsal Fractures
The structure of the foot is complex, consisting of bones, muscles, tendons, and other soft tissues. Of the 26 bones in the foot, 19 are toe bones (phalanges) and metatarsal bones (the long bones in the midfoot). Fractures of the toe and metatarsal bones are common and require evaluation by a podiatrist. The foot and ankle surgeons of the North Shore Podiatry Group are on call 24/7 for emergency care.
What Is a Fracture?
A fracture is a break in the bone. Fractures can be divided into two categories: traumatic fractures and stress fractures.
Traumatic fractures (also called acute fractures) are caused by a direct blow or impact, such as seriously stubbing your toe. Traumatic fractures can be displaced or non-displaced. If the fracture is displaced, the bone is broken in such a way that it has changed in position (dislocated).
Signs and symptoms of a traumatic fracture include:
- You may hear a sound at the time of the break.
- "Pinpoint pain" (pain at the place of impact) at the time the fracture occurs and perhaps for a few hours later, but often the pain goes away after several hours.
- Crooked or abnormal appearance of the toe.
- Bruising and swelling the next day.
- It is not true that "if you can walk on it, it's not broken". Evaluation by a foot and ankle surgeon is always recommended.
They are tiny, hairline breaks that are usually caused by repetitive stress. Stress fractures often afflict athletes who, for example, too rapidly increase their running mileage. They can also be caused by an abnormal foot structure, deformities, or osteoporosis. Improper footwear may also lead to stress fractures. Stress fractures should not be ignored. They require proper medical attention to heal correctly.
Symptoms of stress fractures include:
- Pain with or after normal activity
- Pain that goes away when resting and then returns when standing or during activity
- "Pinpoint pain" (pain at the site of the fracture) when touched
- Swelling, but no bruising
Consequences of Improper Treatment
Some people say that "the doctor can't do anything for a broken bone in the foot." This is not true. In fact, if a fractured toe or metatarsal bone is not treated correctly, complications can develop. For example:
- A deformity in the bony architecture which may limit the ability to move the foot or cause difficulty in fitting shoes
- Arthritis, which may be caused by a fracture in a joint (the juncture where two bones meet), or may be a result of angular deformities that develop when a displaced fracture is severe or hasn't been properly corrected
- Chronic pain and deformity
- Non-union, or failure to heal, can lead to subsequent surgery or chronic pain.
Treatment of Toe Fractures
Fractures of the toe bones are almost always traumatic fractures. Treatment for traumatic fractures depends on the break itself and may include these options:
- Splinting - The toe may be fitted with a splint or removable cast to keep it in a fixed position.
- Surgical Shoe - Wearing a stiff-soled or surgical shoe protects the toe and helps keep it properly positioned.
- "Buddy taping" - the fractured toe to another toe is sometimes appropriate.
- Surgery - If the break is badly displaced or if the joint is affected, surgery may be necessary. Surgery often involves the use of fixation devices, such as pins.
Treatment of Metatarsal Fractures
Breaks in the metatarsal bones may be either stress or traumatic fractures. Certain kinds of fractures of the metatarsal bones present unique challenges.
For example, sometimes a fracture of the first metatarsal bone (behind the big toe) can lead to arthritis. Since the big toe is used so frequently and bears more weight than other toes, arthritis in that area can make it painful to walk, bend, or even stand.
Another type of break, called a Jones fracture, occurs at the base of the fifth metatarsal bone (behind the little toe). It is often misdiagnosed as an ankle sprain, and misdiagnosis can have serious consequences since sprains and fractures require different treatments. Your foot and ankle surgeon is an expert in correctly identifying these conditions as well as other problems of the foot.
Treatment of metatarsal fractures depends on the type and extent of the fracture, and may include:
- Immobilization, casting, or rigid shoe - A stiff-soled shoe or other form of immobilization may be used to protect the fractured bone while it is healing.
- Surgery - Some traumatic fractures of the metatarsal bones require surgery, especially if the break is badly displaced.
- Follow-up care - Your foot and ankle surgeon will provide instructions for care following surgical or non-surgical treatment. Physical therapy, exercises and rehabilitation may be included in a schedule for return to normal activities.
