Snapping fingers, also called stenosing tenosynovitis, are not likely to heal on their own. This is because stenosing tenosynovitis results in a significant jamming of the tendon with the surrounding tendon sheath tissue. For example, frequent movement of the finger results in the gradual formation of an inflammatory lesion between the tendon and the tendon sheath of the finger, resulting in the formation of an enlarged and deformed tendon. Because the elasticity of the tendon sheath itself is limited, once the tendon is deformed, the pressure is relatively high, which will lead to the formation of obvious resistance between the tendon and the tendon sheath, resulting in the inability to move and the emergence of snapping fingers. In this case, it is necessary to open the tendon sheath with a small needle or surgery to release the pressure on the tendon, so that the finger can resume normal activity. Surgery is also the best option, as the needle may cause the stenosis of the tendon sheath to reappear. Surgery removes some of the growths and the more severe compression of the tendon, thus effectively curing the stenosis of the tendon sheath.
