Many people lose their fingers due to various reasons, such as trauma, skeletal deformity, severe infection, etc. Partial loss of fingers, especially the thumb and index finger, not only affects the function of the hand, but also has an unacceptable impact on the appearance of the hand, which has a great impact on life, work and social life. With the economic development and improvement of living standard, in recent years, more and more people with missing fingers come to our hospital and often ask if there is a good way to repair the missing fingers and further improve the appearance of the hand while improving the function of the hand. In the past, there were two main repair options available: (1) surgical treatment, such as toe transplantation. (2) Non-surgical treatment, such as restoration with a glove-like prosthesis (silicone rubber component). If surgical treatment is used, the patient’s toe needs to be taken to repair the missing finger. This surgery is very traumatic and risky, especially considering the absence of the toe in the donor area, and most people would shy away from this method, especially for the families of babies with already imperfect fingers, who cannot accept the toe defect anymore and mostly give up on this treatment method. For this reason, many of our friends are quite interested in prosthetic fingers because they can improve the appearance of the hand without causing new trauma. However, this method is limited in improving the function of the finger and is mostly cosmetic. When pressed further, is there a better way to improve the appearance while enhancing the function of the hand, such as writing, holding chopsticks, shaking hands, etc.? In the past, we shook our heads helplessly because it is not easy to rebuild the function of the fingers. We were disappointed to see them leave the hospital and we, as doctors, did not help them solve their problems. With the rapid development and popularity of computer technology and three-dimensional printing technology, it is making a lot of impossible to become possible and imagination to become reality. Recently, Shanghai Ninth People’s Hospital 3D Printing Center has been established, with this platform and several years of dedicated research experience, we can provide simulation repair for missing fingers – especially for friends with missing distal finger joints, and make personalized 3D metal printed implant type prosthesis to print out your finger only! A new finger not only improves hand function and appearance, but also enhances social self-confidence, quality of life and better integration into society. What kind of method is this? It is a surgical implantation of a stump at the end of a missing finger, similar to dental implants in dentistry, and then the 3D metal printed finger body is fixed to the stump, which is easy to operate, highly simulated, stable, and can be removed when you don’t want to wear it, easy to load and unload, and easy to care for and clean. The surgery can be performed under local anesthesia and you can go home on the same day, making it a short, low-risk and easy procedure. Since the finger prosthesis is made of titanium, it has no effect on general weight retention. The following are some published examples for reference only, the specific efficacy of each patient depends on the different circumstances.
