Current Concepts Review - Tendinosis of the Elbow (Tennis Elbow). Clinical Features and Findings of Histological, Immunohistochemical, and Electron Microscopy Studies*

摘要: Tendon injuries can be divided into several categories on the basis of nature their onset and tissues involved. Acute tendon injuries, such as laceration flexor tendons fingers, are traumatic in nature. Chronic overuse result multiple microtraumatic events that cause disruption internal structure degeneration cells matrix, which fail to mature normal tendon; at times, tendinosis35. The healing acute has been studied from perspective body's response lacerations well after operative intervention35,67. Tendinosis is incompletely understood. Although term tendinitis used frequently often indiscriminately, histopathological studies have shown specimens obtained areas chronic do not contain large numbers macrophages, lymphocytes, or neutrophils26,35,59. Rather, tendinosis appears a degenerative process characterized by presence dense populations fibroblasts, vascular hyperplasia, disorganized collagen. This constellation findings termed angiofibroblastic hyperplasia48. It clear why painful, given absence inflammatory cells, nor it known collagen fails mature. If assumed essentially same pathogenesis regardless where occurs body, then examination patients who tennis elbow serve model for investigation pain other regions reported, rotator cuff, Achilles tendon, patellar ligament, adductors hip, triceps, flexors extensors elbow, plantar fascia7,26,27 …
