Tendon out of groove refers to soft tissue structures such as tendons, fascia, ligaments, synovium and other soft tissue structures that undergo structural changes such as deviation from their original position or dislocation. It is caused by trauma, strain injury, and sudden contraction of soft tissues. If you want to quickly restore the tendon out of the groove, you need to use manipulation to reset the treatment method, after the reset can be immediately effective. To relax muscle tension and spasm, one hand is used to press down on the starting point of the muscle in question, and the other hand is used to press down on the ending point of the muscle in question, pulling it in the direction of the long axis of the muscle. Then use the separation method, first along the longitudinal vertical direction of the out-of-trough soft tissue, maintain a certain amount of pressure, and do repeated pushing action on the soft tissue, so that the out-of-trough soft tissue gradually reset. The same method is used again, along the longitudinal direction, to rationalize the local soft tissues, so that the position of the reset soft tissues are more consistent. After resetting, it is best to use external immobilization treatment to fix the out of groove soft tissue for a period of time, so that the local injury can heal and prevent recurrence.
