Tenosynovial cysts in the dorsal part of the foot often occur in patients in clinical practice. After the occurrence of a tenosynovial cyst in the dorsal part of the foot, there is no uniform and definite price for the specific treatment cost. This is because the cost varies depending on the size of the cyst and the treatment method. If a patient develops a tendon sheath cyst on the back of the foot and takes conservative treatment, local massage is performed in the outpatient clinic using traditional Chinese medicine techniques to rub the cyst, and local pressure bandages are given after the rubbing, and the cost of treatment is around 500-600 yuan. If the patient has a large tendon sheath cyst on the back of the foot, he or she should be hospitalized and undergo a routine surgical incision under local anesthesia to remove the cyst, which costs about $1000-1500. Therefore, patients who have a tendon sheath cyst on the back of the foot should go to the hospital promptly and the doctor will take symptomatic treatment according to the different conditions. In addition, the charges may vary slightly depending on the region and the level of the hospital.
