Deep flexor tendon (FDP) insertion avulsion injury (also known as Jersey Finger) is a common Finger movement injury, divided into 5 types, in which the 5 type Finger FDP avulsion fracture is combined with comminuted fracture of the distal phalanx. The fracture block is divided into a far end, a near end and a palmar side. At present, the first choice of surgical treatment is selected for treating the type of injury, a common fixing method needs to use a kirschner wire to longitudinally fix a far-near end fracture block and a far-interphalangeal joint, in addition, a palm side avulsion bone block needs to be fixed by a drawing method, a polypropylene suture is drawn out from the back side of a deck after the bone block is sutured, and a button is used for knotting to play a pressurizing role. The k-wires and compression buttons are removed and functional exercises are started, typically 6 weeks after surgery. However, the suture drawn from the skin is pressed on the button, and has two problems, namely infection risk, need to be kept dry, regular disinfection and nursing, and the exposed kirschner wire and the risk seriously affect the hand function and the sanitary nursing of the patient; secondly, the button has mechanical compression effect on the nail plate and the nail bed, which causes irreversible deformity of the nail.
