Series of orthopaedic knowledge introduction (Ⅷ)
Mar 15,2021
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...

Series of orthopaedic knowledge introduction (Ⅶ)
Mar 11,2021
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...

Mar 11,2021
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...

Calcaneal Fracture Mechanism Injury
Feb 01,2021
The calcaneus is the largest tarsal bone. Fractures of the calcaneus often involve injuries to other parts. Treatment requires anatomical reduction: restore the overall shape of the calcaneus; restore the subtalar joint flatness and the normal anatomical relationship between the three joint surfaces; restore the GissaneAngle, BohlerAngle, PriesAngle and the weight axis of the hind f...

Series of orthopaedic knowledge introduction (Ⅳ)
Jan 18,2021
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...

Series of orthopaedic knowledge introduction (Ⅲ)
Jan 15,2021
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 ...
