Accidents Often Cause Foot and Ankle Injuries
Strains, sprains, and fractures are the most prevalent (more than one million people in US annually) ankle injuries, often occurs during sports and recreational activities. But people also commonly suffer these injuries while walking or falling from collapsing stairs or falling of a construction site. Such injuries of ankle are Adduction injuries, Abduction injuries, Pronation–External rotation injuries, Supination-External rotation injuries and Vertical compression injuries. These injuries are usually fracture of bones and strains of the ankle ligaments. An ankle joint is made up of 3 bones (tibia, fibula, and talus), a fibrous capsule which contains synovial fluid (allows smooth movements of the joint surfaces) and several ligaments that stabilize the joint. Ankle fractures are classified according to the location and type of ankle bone involved. The different types of ankle fractures are:
- Lateral Malleolus fracture in which the lateral malleolus, the outer part of the ankle, is fractured.
- Medial Malleolus fracture in which the medial malleolus, the inner part of the ankle, is fractured.
- Posterior Malleolus fracture in which the posterior malleolus, the bony hump of the tibia, is fractured.
- Bimalleolar fractures in which both lateral and medial malleolus bones are fractured.
- Trimalleolar fractures in which all three lateral, medial, and posterior bones are fractured.
- Syndesmotic injury, also called a high ankle sprain, is usually not a fracture, but can be treated as a fracture.
HEEL BONES FRACTURES
Fractures of Calcaneum bone: Calcaneum bone fractures are usually caused by fall from height onto the heels, thus both heels may be injured at the same time. The fracture may be (i) an isolated crack fracture usually in the region of tuberosity; or (ii) more often a compression injury where the bone is shattered like an egg shell. The degree of displacement varies according to the severity of trauma. The fracture may be one of the following types
- Undisplaced fractures resulting from a minimal trauma
- Extra-articular fracture where the articular surface remain intact, and the force splits the calcaneal tuberosity
- Intra-articular fracture when the articular surface of the calcaneum fails to withstand the stress. It is shattered and driven downwards into the body of the bone, crushing the delicate trabeculae of the cancellous bone into powder. This is commonest type of fracture.
Fractures of the Tarsal bones: Fracture of Talus bone: Fracture of neck of the talus results from forced dorsiflexion of the ankle. This may be associated with dislocation of the body of the talus backward, out of the ankle-mortise. Vascularity of the body of the talus may be compromised.
Fractures and dislocation of other Tarsal bones are uncommon.
Fractures of Metatarsal bones are caused by direct violence from a heavy object falling onto the foot. A metatarsal fracture can be caused by repeated stress without any specific injury (march Fracture).One or more metatarsal fractures of the shaft of the bones can be due to crush injuries.
Fractures of Phalanges of the Toes These are common injuries, most often resulting from fall of a heavy object, or twisting of the toes. The great toe is injured most commonly.
