Tendon and degeneration or weakening of the tendons, which may eventually lead to tendon rupture. Tendinopathies can be caused by a number of factors relating to the tendon extracellular matrix (ECM), and their classification has been difficult because their symptoms and histopathology often are similar. The first category of tendinopathy is paratenonitis, which refers to inflammation of the paratenon, or paratendinous sheet located between the tendon and its sheath. Tendinosis refers to non-inflammatory injury to the tendon at the cellular level. The degradation is caused by damage to collagen, cells, and the vascular components of the tendon, and is known to
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,
