Fibula - tubular, thin and long shin bone.  Shin rights. Fibula
 It consists of a body and two epiphyses, respectively, upper and lower. The distal or lower end of the bone is an important component of the ankle is called lateral or outer ankle. Lateral ankle stabilizer is an outer bone of the ankle joint.

The structure of the fibula

The body has a prismatic triangular bone shape, bent backward and twisted about the longitudinal axis. Fibula has three surfaces: rear, lateral and medial, which are separated from each other by three ridges.

The front edge has the shape of a sharp ridge and separates the lateral surface of the medial. The medial ridge located between the medial and posterior surfaces of the bones, and between the lateral and rear surfaces of the rear edge is located. On the rear surface located nutritional hole which extends distally nutrient feed. On the medial surface of the interosseous you can see the edge.

The upper epiphysis of the fibula head forms, which with the help of the articular surface is connected to the tibia. The upper portion of the head has a pointed tip shape, and is called the head. From the head of the body is separated by means of cervical fibula.

Lower epiphysis bone forms the lateral malleolus. Its outer surface is well detectable through the skin. On the medial surface of the lateral malleolus is articular surface, by which bone is connected to the outer part of the talus. Slightly higher on the fibula is a rough surface, which connects to the fibular notch of the tibia.

On the back surface of the outer ankle can see traces of peroneus longus tendon - malleolar sulcus.

Types of fractures fibula

Fractures are at different levels of the fibula. Advantageously, the bone breaks in the lateral malleolus. In turn, the lateral malleolus fracture of the tibia occurs at its various levels. Generally, a fracture fibula accompanied by dislocation or subluxation of the foot, shortening of bones and rupture of the distal syndesmosis interosseous.

There are oblique, comminuted, transverse and spiral fractures fragmentary fibula.

The main symptoms of a fracture include:  Options fractures large and fibula

  • pain on palpation of the outer ankle;
  • swelling;
  • pain when axial load on the bone;
  • ankle pain on motion.

Treatment of fractures of the fibula

The main purpose is to compare the conservative treatment and retention of bone fragments. Doctor traumatologist held reposition, through which eliminates the subluxation of the foot and displacement of the bone fragments. If the fracture between reposition reposition successful and satisfactory condition fragments, feet and legs are fixed with plaster cast or a special brace.

If you reposition does not give satisfactory results and the displacement of bone fragments preserved prescribe surgery fibula, which consists of several stages:

  • held open reduction of bone fragments;
  • eliminated a subluxation of the foot;
  • Bone fragments are fixed by means of implants (pins, screws, plates).
