easily in any direction. Similarly, a weight-bearing cast shoe (cast boot, cast sandal) can help the patient walk during convalescence. Additionally, a castshoe can simply protect the patient's casted foot while helping to maintain better hygiene by preventing the cast from directly contacting potentially dirty or wet ground surfaces. Where the patient is not to walk on the injured limb, crutches or a wheelchair may be provided. The foot's under-sole portion of a leg cast may be extended terminating at the tip of the patient's toes, to create a rigid support that limits motion of the metatarsals in both weight bearing and non-weight bearing leg casts. These are referred to as toeplates in the orthopedic discipline of medicine. This addition may be applied to further support and stabilize the metatarsals by limiting motion through a higher degree of immobilization, as well as protecting the toes from additional blunt force trauma. Typically leg casts with no toeplate are prescribed for injuries to the foot and metatarsals. Ordinarily, a leg cast applied for the treatment of a stable ankle fracture would not use the toeplate design because there is no need to immobilize and limit the motion of the patient's toes. Cylinder In some cases, a cast may include the upper and lower arm and the elbow, but leave the wrist and hand free, or the upper and lower leg and the knee, leaving the foot and ankle free. Such a cast may be called a cylinder cast. Where the wrist or ankle is included, it may be called a long arm or long leg cast. Body Body casts, which cover the trunk of the body, and in some cases the neck up to or including the head (see Minerva Cast, below) or one or more limbs, are rarely used today, and are most commonly used in the cases of small children, who cannot be trusted to comply with a back brace, or in cases of radical surgery to repair an injury or other defect. A body cast that encases the trunk (with "straps" over the shoulders) is usually called a body jacket. These are often very uncomfortable. EDF cast An EDF (elongation, derotation, flexion) cast is used for the treatment of Infantile Idiopathic scoliosis. This method of treatment for correction was developed by UK scoliosis specialist Min Mehta. Scoliosis is a 3-dimensional problem that requires correction in all three planes. The
