It mostly impacts on the tendons and causes a microscopic tear of them. As a result, it may cause the formation granulation tissue and fibrosis.
1. Epicondylitis: This is due to single or multiple tears in the common extensor origin, periostitis, proliferation of extensor carpi radialisbrevis(ECRB), etc.
