Patients with dorsalis pedis tendon sheath cysts are usually difficult to heal on their own and require treatment, as follows: First, dorsalis pedis tendon sheath cysts are subjected to repeated friction by the oblique surface, the cysts will continue to grow and cannot be absorbed by themselves, so it is difficult to heal on their own. Second, more obvious, serious dorsalis pedis tendon sheath cysts, usually using hot compresses and other treatments will not shrink, need to use surgery to remove to cure. The recurrence rate is quite high because the cyst fluid is extracted by closed injection, which also easily recurs and produces cyst fluid, and the cyst wall still exists. Surgical treatment is required to completely remove the cyst and remove the cyst wall completely in order to cure the tendon sheath cyst completely. After surgery, the area should be bandaged with pressure to avoid the formation of a hematoma and the occurrence of infection.
