Abstract:

BACKGROUND: Treatment methods of intertrochanteric fracture are various, which can be divided into extramedullary fixation system, intramedullary fixation system and arthroplasty. Different treatment methods have their own advantages and disadvantages. With the deepening of research, relevant controversial issues have become the hotspot of clinical research.
OBJECTIVE: To review the improvement of internal fixation device for intertrochanteric fracture, the changes of operative methods and the related controversial issues, thus providing reference for further clinical research.
METHODS: The first author retrieved CNKI, WanFang, PubMed, Web of Science and SpringerLink databases with the keywords of “intertrochanteric fracture, osteoporosis, hip fracture, fracture fixation, internal, arthroplasty, displacement, hip, bone plates, internal fixators, prosthesis implantation, aged” in Chinese and English, respectively. Relevant studies published from January 2008 to August 2018 were collected, and finally 56 eligible studies were included for analysis by reading the title and abstract.
RESULTS AND CONCLUSION: (1) With the in-depth study on the characteristics of anatomy and biomechanics of proximal femur, the intertrochanteric fracture classification system is gradually developing and improving to correctly evaluate the severity of fracture and determine the prognosis. (2) There is no unified “gold standard” for the surgical treatment of intertrochanteric fracture. Therefore, individualized treatment plan should be selected for the patient dialectically. (3) As a “turn-of-the-century surgery” in the history of orthopedic surgery, arthroplasty is increasingly applied in elderly patients with intertrochanteric fractures, but the surgical indications should be strictly controlled. (4) There are many controversial issues in the treatment of intertrochanteric fracture, and a large number of multi-center and big data clinical studies are still needed to solve the problem. (5) The rapid development of digital medicine will change the treatment pattern of intertrochanteric fracture.
