The lack of grip after surgery of the tendon of the dorsum of the hand can be recovered through physical therapy and strengthening of functional exercises. The length of tendon is shorter than normal after surgical repair of ruptured tendon of the back of the hand, and it needs to be fixed in a plaster cast after surgery. Prolonged fixation will cause localized adhesion around the tendon, and the phenomenon of poor grip will occur, which is a common phenomenon in tendon injuries. This is a common phenomenon in tendon injuries. You can use hot water to burn your hands and massage the surgical site to promote the recovery of adhesion. At the same time, we should strengthen the functional exercise, such as active fist, to promote the functional recovery of the adhesion site, after a period of rehabilitation training, the symptoms of tight grip can be relieved or even disappear. If the hand grip is not tight after hand back tendon surgery, it is recommended that the patient go to the hospital for medical examination, improve the examination, and receive regular treatment.
