Tendon sheath cysts can be seen in the Department of Orthopaedics or the Department of Hand and Foot Surgery, which specializes in tendon sheath cysts; orthopaedics may also be chosen in hospitals of lower grades or where the division of departments is unclear. 1. Hand and Foot Surgery: Tendon sheath cysts are common benign swellings on the surface of the body, most of them are round swellings formed due to the excessive movement of the tendon sheaths, resulting in the increase of intra-articular exudation, and their contents are usually liquid with the outer layer of cystic wall tissues, which are mostly found in the carpal joints. Hand and foot surgery belongs to orthopedics department, which is specialized in handling hand and foot diseases, and there are surgical instruments in the department that specialize in handling fine parts of the hand and foot, which can deal with tendon sheath cysts more accurately. 2. Orthopedics: Some hospitals may not have the department of hand and foot surgery due to the limitation of hospital level or unclear division of departments, etc. Patients can choose to go to orthopedics for consultation. Although tendon sheath cysts belong to the specialty of hand and foot surgery, hand and foot surgery is a branch of orthopedics, and professional orthopedic surgeons can also optimize the treatment of tendon sheath cysts. If a tendon sheath cyst is diagnosed, it is recommended that it be treated early in order to minimize the adverse effects of the disease.
