How long the wrist can be flexed after wrist tendon sheath cyst surgery varies from person to person, mainly related to the specific way of surgery, if minimally invasive surgery needs 2~3 weeks of timing after surgery, and direct incision needs 3~4 weeks to resume normal wrist activity function. 1. Minimally invasive surgery: refers to the removal of tendon sheath cysts under arthroscopy, which may preserve part of the tendon sheath. Minimally invasive surgery has a smaller incision, the tendon sheath damage is relatively less serious, and the recovery time is relatively shorter, usually about 2~3 weeks to resume normal wrist activity function such as bending. 2. Surgery: direct surgery to remove the diseased tendon sheath and cyst at the same time, wound healing takes some time, open surgery incision is relatively large, the degree of damage to the surrounding tissues is also relatively large, the recovery time is relatively longer, it usually takes 3~4 weeks to restore the normal function of the wrist activities. During the postoperative recovery period of wrist tendon sheath cyst, appropriate rehabilitation training can be carried out under the guidance of the doctor, such as practicing finger flexion and extension activities and wrist joint rotation. After wrist tendon sheath cyst surgery, the recovery time is different for different patients, so they should strictly follow the postoperative precautions and carry out rehabilitation training under the doctor’s guidance, which is conducive to accelerating the recovery of wrist movement function.
