"who returned to basketball after surgery. This condition, which occurs in adolescents and adults, can be associated with previous trauma. The true cause is not known. Most commonly, hallux rigidus is thought to be caused by wear and tear of the first metatarsophalangeal joint. In 1988, Hattrup and Johnson described the following radiographic classification system: Early treatment for mild cases of hallux rigidus may include prescription foot orthotics, shoe modifications (to take the pressure off the toe and/or facilitate walking), specialized footwear ('rocker-sole' shoes), medications (anti-inflammatory drugs) or injection therapy (corticosteroids to reduce inflammation and pain).

The corpus callosum forms the floor of the longitudinal fissure that separates the two cerebral hemispheres. It also forms part of the roof of the lateral ventricles. The corpus callosum has four main parts; individual nerve tracts that connect different parts of the hemispheres. These are the rostrum, the genu, the trunk or body, and the splenium. A narrowed part between the trunk and the splenium is known as the isthmus. The front part of the corpus callosum, towards the frontal"
