Last issue we learned about that bone, bone attachment and skeletal muscle make up our motor system. On this issue, we would like to talk about the bone which is a sort of framework to support our body under the influence of gravity. Bone is made up of sclerotin, periosteum and bone marrow. To be specific, sclerotin is composed of bone tissue and can be divided into compact bone and spongy bone by structure. The compact bones are distributed on the surface of bone. Spongy bones are like spongy, which consist of interwoven trabeculaes. Trabeculaes are aligned parallel to the direction of stress and tension on the bone, so that the bone can support heavy mass of our bodies. The periosteum is mainly composed of fibrous connective tissue, covering the surface of bone outside the articular surface where is rich in nerves, blood vessels and lymphatic vessels, and plays an important role in the nutritional regeneration and sensation of bone. The periosteum...

  Last issue we learned about the components of our body. So we have already known that the human body can be divided into 10 parts from appearance, meanwhile, many organs can compose 9 systems respectively. On this issue, we would like to talk about the first system of our body, motor system. To be specific, the motor system consists of bone, bone attachment and skeletal muscle, which accounts for about 50 to 70 percent of an adult's body weight. And the motor system performs support, protection and motor functions. The small bones of the entire body are connected in different forms to form regional skeletons, support bodies, protect internal organs, maintain body posture, give the basic structures of the body, and provide broad attachment points for skeletal muscles. The bone is also an important hematopoietic organ. In the meantime, the bones are able to store calcium, phosphorus and other minerals in the body. Skeletal muscle is the power device of the m...

  Treatment of Osteoporotic Vertebral Fractures. Both PVP and PKP can definitely relieve the pain symptoms of patients. The pain relief rate of osteoporotic vertebral compression fractures exceeds 90%, and the pain relief rate of tumorous vertebral body lesions is between 75%-90%. The operation of PVP is relatively simple, the operation time is short, no balloon expansion operation is required, the X-ray exposure time of the operator and the patient is shorter, and the incidence of puncture-related complications are relatively low, but the bone cement needs to be injected into the vertebral body under high pressure conditions, thus leading to a higher incidence of bone cement leakage. PKP uses the balloon expansion in the vertebral body to create a cavity. Under low pressure, high viscosity bone cement is injected into the vertebral cavity. The incidence of bone cement leakage is significantly reduced and its safety, compared with PVP, is greatly improved, especial...

  Treatment of Phalangeal Fractures. Phalange neck fracturesare common in children and rare in adults. This type of fracture is difficult to treat. Regarding the fixation method, we can use kirschner wire to restore and fix the fracture but this method requires exquisite surgical techniques otherwise the patient will possibly suffer some postoperative complications, for example, joint stiffness, delayed union, and nonunion caused by damage to articular cartilage and iatrogenic fractures due to multiple passage times of wires through the phalange. We can refer to the below picture for the tips of surgical techniques of kirschner wire fixation. If you do not prefer the fixation via kirschner wire, you can choose our mini locking fixation system, which provides a complete solution for phalange fractures. The plates are designed with low profile and anatomical contouring and can easily enrich the clinical choices for the phalange fractures. #Phalange Fra...

  Last issue we looked back on the history of anatomy. In this issue, we would like to talk about the components of our body, especially the systems of our body. The human body can be divided into 10 parts from the appearance, and each part can be subdivided into several small parts. Important parts of the human body are: head (including cranium, face), neck (including neck, nape), back, chest, abdomen, perineum (after four parts collectively called the trunk cadres) and left, right upper limbs, and left, right lower limbs. Cells are the basic units of the body. Cells and intercellular substance constitute organizations. The body's basic organization includes epithelial tissue, connective tissue, muscle tissue and nerve tissue. Several organizations together to form organs. According to different functions, many organs composes 9 systems respectively: motor system for movement of the body; digestive system f...

  One great scientist said, to understand orthopaedic medicine, one must first understand anatomy, and to understand anatomy, one must first understand its history and development . Medical records of anatomy began from Hippocrates, a famous ancient Greek doctor, who believed that the heart had two chambers and two chambers. Aristotle, another Greek scholar, did an animal dissection, suggesting that the heart is the center of blood circulation , and d istinguishing nerves from tendons , but he mistakenly applied the results of animal dissection to the human body . And, ancient Greek medical scientist Herophilus, he found and named " duodenum ," he named " prostate ", " the ciliary body ", " retina ", " lacteal and lymphatic ", studying the liver and pancreas , and female uterus and fallopian tubes . Galen's Classic of Medicine was an authoritative masterpiece of Western medicine before the 16th century. There were many anat...
