Internal fixation of digital metacarpal fracture plate is a common surgical method for the treatment of digital metacarpal fracture. During the procedure, the fractured bone is placed back in place and then a plate is used to hold the fracture together. This method can restore the stability of the fracture site and promote fracture healing. During surgery, the surgeon will select the appropriate plate for fixation based on the location and severity of the fracture. Titanium plates are usually made of stainless steel or titanium alloy and are strong and rigid enough to support the fracture site. The doctor will attach the plates to both sides of the fracture and use screws or wires to attach the fracture to the plates. After surgery, the patient needs to undergo a period of rehabilitation training to restore the function and strength of the finger. During recovery, the patient may need physical therapy and functional exercises to help the finger return to normal function.
