Abstract: BACKGROUND: Tubular bone fractures of limbs are common in traumatic orthopedics, among which anatomic intramedullary nailing has been gradually applied in clinical treatment in recent years, and has achieved good curative effect.
OBJECTIVE: To summarize the application characteristics, advantages and development direction of anatomic intramedullary nailing in tubular bone fractures of limbs.
METHODS: PubMed, Web of science, CNKI, Wanfang and VIP were searched for articles published from January 1900 to May 2020. The key words were “tubular bone, anatomic intramedullary nail, ulna, radius, humerus, femur, tibia, fibula” in Chinese and English. Totally 379 articles were initially examined, and 34 were finally included for review and analysis according to inclusion and exclusion criteria.
RESULTS AND CONCLUSION: (1) The development history and application characteristics of anatomic intramedullary nailing in tubular bone of limbs were introduced in this paper, which was considered to have a broad clinical prospect. (2) Intramedullary nailing is gradually replacing external fixation in the treatment of tubular bone fracture, and anatomical intramedullary nailing will become the first choice of treatment. (3) Anatomic intramedullary nailing provides a better choice for intramedullary fixation of tubular bones of limbs and reduces the occurrence of related complications because its main nailing structure is more in line with the unique design of tubular bone marrow cavity of human body and the combination of distal and proximal screws with the main nailing to provide stronger holding force and anti-rotation ability. (4) The anatomic intramedullary nails have been applied in foreign countries and later in China. For example, the ZNN anatomic intramedullary nails produced by Zimmer Company in the United States are mostly used in the treatment of lower limb tubular bone fractures. In China, the anatomic intramedullary nails have just been introduced into the treatment of hip fractures (intertrochanteric and subtrochanteric fractures) and are rarely used in the treatment of tibial shaft fractures. (5) In the future, the new generation of anatomic intramedullary nails will combine biological detection, information sensing and other technologies more efficiently, so as to realize the technology and intelligence of materials.
