This paper provides a concise overview of fractures of the tibia and fibula, the two long bones of the lower leg. It examines the anatomy and relative vulnerability of these bones, identifies common causes such as high-energy impacts and sports injuries, and outlines the populations most frequently affected. The paper then describes the characteristic symptoms of a fracture, the diagnostic process including X-ray and CT imaging, and the range of treatment options available — from casting and splinting for minor fractures to surgical intervention with metal hardware for more severe breaks. The importance of early diagnosis and proper rehabilitation is emphasized throughout.
The human body contains four specific long bones: the femur, humerus, tibia, and fibula. The tibia and fibula are located in the lower part of the leg, between the knee and the ankle. The tibia is the larger of the two and serves as the primary weight-bearing bone, but it is also the most common long bone to fracture. Because serious complications can arise from a fractured tibia or fibula, it is vitally important to "be aware of the early warning signs" (Semer, 2001, p. 205). Failure to treat a fracture early can result in permanent damage, including disability, paralysis, or even amputation. With proper treatment, however, a fracture of the tibia, the fibula, or both can "heal without complications and a person is able to resume his or her normal activities" (Semer, 2001, p. 205).
The tibia is a strong bone and difficult to fracture; nevertheless, people frequently manage to break even their strongest bones. High-energy impacts — such as those sustained in a motorcycle or car crash — are a common means of fracturing the tibia or fibula. The most common causes, however, are sports injuries: falling while skiing, colliding with others during football or soccer, or sustaining some other type of force-impact trauma. Because of the amount of energy required to fracture these bones, those most commonly affected are young, active individuals who engage in sports and extreme activities such as rock climbing or skydiving.
If someone has fractured their tibia or fibula, the most common symptoms include "pain, inability to walk or bear weight on the leg, deformity or instability of the leg, bone 'tenting' the skin or protruding through a break in the skin, and occasional loss of feeling in the foot" ("Tibia (Shinbone) Shaft Fractures"). When these symptoms are present, a medical examination is essential. The physician will look for bruising, swelling, bones protruding under or through the skin, and instability of the leg.
The doctor will most likely order an X-ray of the lower leg, as a fracture can readily be identified on a radiograph. A fracture of the tibia or fibula appears as a dark line or crack in the bone. In the case of a more serious fracture, the bone will be visibly cracked and separated into two or more distinct pieces (Von Laer, 2004, p. 371). If the X-ray suggests that the fracture may extend into the knee or ankle area, a computed tomography (CT) scan is often recommended, as it can provide more detailed information about the severity and extent of the injury.
