The cost of finger joint replacement mainly includes the cost of surgery and prosthesis, which is related to a variety of factors such as individual’s physical condition, the level of hospital, the source of joint material, etc. Generally speaking, it ranges from 40,000 yuan to 50,000 yuan. Joint replacement is a mature restorative surgery. When a patient suffers from dysfunction or serious loss of function in a joint, the original joint needs to be replaced by an artificial joint to play a role. Generally speaking, the function of the artificial joint is no different from that of the original joint, and the quality of life of the patient can be greatly improved. Joint replacement surgery can be considered when a patient has joint surface damage caused by trauma or when a disease causes degenerative joint changes. If the patient has significant infection at the finger joints or in the surgical area, such as abscesses or ulcers, or active infection such as pneumonia and systemic decubitus ulcers, the patient is not eligible for surgery and the infection should be controlled before surgery is performed. Older patients, patients with high blood pressure, or patients with heart disease should be admitted to the hospital for a pre-operative examination before undergoing surgery. Detailed information about the cost of the surgery should be consulted at the hospital and the surgery should be performed at a regular hospital.
