Prosthesis of lower extremities or lower limb prosthesis. In human anatomy, the lower limb or pelvic member is each of the two extremities that are attached to the trunk through the pelvis by the hip joint. They have the function of supporting the weight of the body in the bipedal position and making possible the displacements by means of the contraction of its powerful musculature.
Within the lower limb there are several zones; each lower member consists of several main segments:
The pelvic waist or pelvis. It is a bony ring that is formed by the sacral bone in the posterior region and the right and left coxal bones. Both join in front at the symphysis pubis that closes the ring.
Thigh: his skeleton is a single bone; The femur. In this area transfemoral prosthesis or prothesis above the knee would be located
Patella: It is the area of union between the thigh and the leg. There are different types of knee prostheses .
Leg: formed by the tibia and the fibula or fibula. In this area the leg prosthesis is located, or also called transtibial or transtibial prosthesis.
Ankle: Region in which the leg is joined with the foot.
Pie, in turn formed by three segments: Tarso, Metatarso, Falange. Foot prosthesis
