Double Medical Compound Compression System CCS Clinical Q&A
Jun 28,2021
Q1: There is no antirotation effect when pressurized. But for Synthes it inserts two screws and then pressurizes, is the antirotation effect better? A: After inserting Lag Screw, the thread of it is tightly occluded with the bone. And when pressurize, the lag screw is pulled vertically and backward and does not rotate. So theoretically the fracture end and Lag Screw are not easy to rotate. If stil...

Series of orthopaedic knowledge introduction (09)
Mar 15,2021
Last issue we learned about the plasticity of bone. On this issue, we would like to talk about axial skeleton, which includes trunk bones and skull. To be specific, the trunk consists of 24 vertebrae, a sacrum, a coccyx, a sternum, and 12 pairs of ribs that contribute to the formation of the spine, the bony thorax, and the pelvis, respectively. The skull consists of 23 bones (the 3 pairs of ossicl...

Last issue we learned about membranous bone and chondrogenic bone. On this issue, we would like to talk about the plasticity of bone. To be specific, osteoporosis occurs when neuroregulation is reduced. People with palsy disease may suffer from bone decalcification, osteoporosis and bone resorption due to nerve injury, and even spontaneous fracture. Endocrine has a great influence on the deve...

The last issue we learned about the chemical composition and physical properties of bone. On this issue, we would like to talk about membranous bone and chondrogenic bone. Bone occurs in the mesodermal mesenchyma. From the 8th week of the embryo, the mesenchyma is membranous and being ossified gradually, which is called membranous bone. Or the mesenchyma first develop into cartilage...

The last issue we learned about blood vessels, lymphatic vessels, and nerves. On this issue, we would like to talk about chemical composition and physical properties of bone. Bone is composed of organic and inorganic matter. Organic matter is mainly composed of collagen fiber bundles and sticky polyglycoproteins which form the scaffold of bone and give it elasticity and toughness. The inorgan...

The last issue we learned about that bone is made up of sclerotin, periosteum and bone marrow. On this issue, we would like to talk about blood vessels, lymphatic vessels, and nerves. Blood vessels: the arteries of long bones include the trophising artery, epiphyseal artery, epiphyseal artery and periosteum artery. It can be divided into the diaphyseal system, epiphyseal - metaphyseal system, peri...
