Genu Valgum: An inward slant of the thigh in which the knees are close together and the ankles far apart. Genu valgum can develop due to skeletal and joint dysplasias (e.g., OSTEOARTHRITIS; HURLER SYNDROME); and malnutrition (e.g., RICKETS; FLUORIDE POISONING).Genu Varum: An outward slant of the thigh in which the knees are wide apart and the ankles close together. Genu varum can develop due to skeletal and joint dysplasia (e.g., OSTEOARTHRITIS; Blount's disease); and malnutrition (e.g., RICKETS; FLUORIDE POISONING).Surgical Stapling: A technique of closing incisions and wounds, or of joining and connecting tissues, in which staples are used as sutures.Femur: The longest and largest bone of the skeleton, it is situated between the hip and the knee.Tibia: The second longest bone of the skeleton. It is located on the medial side of the lower leg, articulating with the FIBULA laterally, the TALUS distally, and the FEMUR proximally.Knee Joint: A synovial hinge connection formed between the bones of the FEMUR; TIBIA; and PATELLA.Epiphyses: The head of a long bone that is separated from the shaft by the epiphyseal plate until bone growth stops. At that time, the plate disappears and the head and shaft are united.Bone Malalignment: Displacement of bones out of line in relation to joints. It may be congenital or traumatic in origin.Corpus Callosum: Broad plate of dense myelinated fibers that reciprocally interconnect regions of the cortex in all lobes with corresponding regions of the opposite hemisphere. The corpus callosum is located deep in the longitudinal fissure.
