Once the collateral ligament is calcified, there is no way to restore it to its normal state. The reason for calcification of the collar ligament is mainly due to various acute and chronic adverse factors, which stimulate the collar ligament for a long time, so that the collar ligament is repeatedly stretched and repeatedly forms exudation, and after the exudation is not absorbed in time and the inflammation is not cured in time, calcium ions will be gradually deposited on the ligament, which will gradually calcify the collar ligament in a longer time. Calcification is an irreversible process, once the ligament and become bony tissue, there is no way to make it return from bony tissue to soft tissue nature through treatment, so once the collar ligament is calcified, it cannot be restored.
