Abstract: BACKGROUND: Unstable distal clavicle fractures need surgical treatment, and there is no gold standard for the intraoperative implants. The improvement of the implants and the progress of technology are the focus of research in recent years.
OBJECTIVE: To summarize the new progress of the treatment of distal clavicle fracture with internal fixation, to explore the principles and advantages and disadvantages of various surgical treatment methods, and to guide the direction of further research.
METHODS: Chinese database of Wanfang, VIP, and China National Knowledge Infrastructure was searched by the first and the second authors. The search terms were “distal clavicular fracture; classification; biomechanics; internal fixation; tendon reconstruction; complications; prognosis”. At the same time, the English database of PubMed and Web of Science was retrieved with the search terms of “patella fracture, classification, biomechanics, implants, tendon reconstruction, complications, prognosis”. The retrieval period was from July 2015 to August 2020. A total of 466 articles were retrieved. According to the inclusion and exclusion criteria, 48 articles were finally selected and summarized. 
RESULTS AND CONCLUSION: (1) Unstable fracture of distal clavicle needs to be treated by operation, which should not only consider fracture treatment, but also consider the instability caused by coracoclavicular ligament injury. (2) There are many kinds of implants for distal clavicle fracture, but there is no unified gold standard. (3) Surgical treatment methods include Kirschner wire tension band internal fixation, hook plate internal fixation, locking plate internal fixation, ligament strengthening, and reconstruction technology. Ligament reconstruction technology is more and more popular; the improvement of the internal object and technology is the focus of research.

Key words: distal clavicle fracture, implants, internal fixation, tendon reconstruction, biomechanics, review
