Tendon ornithischian dinosaurs, ossified axial muscle tendons form a latticework along the neural and haemal spines on the tail, presumably for support. Tendon A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to bone, while tendons connect muscle to bone for a proper functioning of the body. Histologically, tendons consist of dense regular connective tissue fascicles encased in dense irregular connective tissue sheaths. Normal healthy tendons are composed mostly of parallel arrays
Tendon transfer used to restore a single function. Transfer of one tendon to restore multiple functions will compromise strength and movement. These are examples of commonly performed tendon transfers. Many of the lower extremity tendon transfers were performed during the nineteenth century to improve ambulation in polio patients due to post-poliomyelitis paralysis. In the beginning o twentieth century, tendon transfers were used to correct congenital talipes equina. Tendon transfers were extensively performed during World Wars I and II to patients with upper extremity injuries. Tendon transfer A tendon transfer is a surgical process in which the insertion of a tendon is moved,
