背景技术Background technique
在骨折治疗中，如何根据骨骼结构进行复位和固定是非常重要的内容，这将直接影响到骨折部位的复原程度，成为手术成败的关键。从解剖学上看骨主要由骨质、骨膜、骨髓等构造。骨质分骨密质和骨松质两类，骨密质致密坚实，耐压性强，布于骨的表面。骨松质位于骨的内部，由交织成网的骨小梁构成，结构疏松。骨小梁的排列方向，多数都与该骨的承受压力的方向一致。骨小梁可以分为主要张力骨小梁、次要张力骨小梁及主要压力骨小梁、次要压力骨小梁，在不同部位骨小梁走形方向不同。人体的骨骼在骨折再塑过程的变化规律显示，骨折后如有移位，在凹侧将有明显骨痂形成，其内部骨小梁将沿着压应力的传递方向排列，而在凸侧将有骨的吸收。In fracture treatment, how to perform reduction and fixation according to the bone structure is very important, which will directly affect the degree of recovery of the fracture site and become the key to the success of the operation. Anatomically, bone is mainly composed of bone, periosteum, and bone marrow. Bone is divided into two types: cortical bone and cancellous bone. The compact bone is dense and firm, with strong pressure resistance, and is distributed on the surface of the bone. Cancellous bone is located inside the bone and is composed of interwoven bone trabeculae with a loose structure. Most of the alignment directions of bone trabeculae are consistent with the direction of the bone bearing pressure. Trabecular bone can be divided into primary tension trabecular bone, secondary tension trabecular bone, primary stress trabecular bone, and secondary stress trabecular bone. The direction of trabecular bone deformation is different in different parts. The change law of human bones in the process of fracture remodeling shows that if there is displacement after fracture, there will be obvious callus formation on the concave side, and the internal bone trabeculae will be arranged along the direction of compressive stress transmission, while on the convex side there will be callus formation. There is bone resorption.
传统骨折内固定物置入后由于内置物的容积占位效应，破坏断端骨小梁，影响两个断端的骨小梁的生长、并恢复其连续性，髓内外骨痂生长不均衡，尤其是老年人骨质疏松性骨折，可能骨皮质愈合后，骨松质愈合较差，影响骨骼愈合强度，有时候可能导致骨折延迟愈合及再骨折。After the traditional fracture internal fixation is placed, due to the volume occupying effect of the implant, the bone trabecula at the stump end is destroyed, the growth of the bone trabecula at the two stump ends is affected, and its continuity is restored, and the growth of the extramedullary callus is uneven, especially It is an osteoporotic fracture in the elderly. After the cortical bone heals, the cancellous bone heals poorly, which affects the bone healing strength, and sometimes may lead to delayed fracture union and re-fracture.
随着骨科内固定技术的不断发展，非常有必要设计新的固定装置，使骨折治疗在生物学及生物力学原理的指导下，使骨折的皮质与主要骨小梁同时生长重建，实现髓内外骨折同时愈合。这样会加快骨折愈合速度、提高骨折愈合质量和强度，降低骨折不愈合、延迟愈合、内固定物松动、断裂等并发症的发生率。With the continuous development of orthopedic internal fixation technology, it is very necessary to design a new fixation device, so that the fracture treatment can be guided by the principles of biology and biomechanics, so that the cortex of the fracture and the main trabecular bone can grow and reconstruct at the same time, so as to realize extramedullary fractures. Heal at the same time. This will accelerate the fracture healing speed, improve the quality and strength of fracture healing, and reduce the incidence of complications such as fracture nonunion, delayed union, internal fixation loosening, and fracture.
