What are the categories of orthopedic consumables such as trauma, joints and spine? Anything else? What products are included in each category?

1. Generally speaking, orthopedics can be divided into three categories. Some hospitals are not clearly divided. In general, it is joints, spine and trauma. Joints include the whole human body joints: knee joint, hip joint, elbow joint, wrist joint, ankle joint, knuckle joint and shoulder joint, all of which can be replaced. Some are biology and cement, some are imported and made in China, and some are revised and primary. The spine is divided into cervical vertebrae, thoracic vertebrae and lumbar vertebrae, with anterior and posterior approaches. According to the anatomical structure of the vertebral body, there are pedicle screws, interbody fusion cages, dynamic fixation between spinous processes, domestic and imported ones, as well as vertebroplasty (PKP, PVP) and vertebral body replacement. There are many injuries, mainly steel plates and intramedullary nails. I was injured, and some joints and spinal fractures were also injured. Usually, the injury is a limb fracture outside the joint spine.

2. There are many kinds of steel plates, which can't be finished in one or two sentences. Generally, companies have training and materials to read, so I won't say much. Usually, I mainly remember more, so it is not difficult.

3. The third question suggests that brothers should look at anatomy and mechanics more. Both T-type and L-type are named according to anatomical structure. Shape and structure, 45 or inside and outside, front and back, proximal and distal are all anatomical concepts. When the anatomy is familiar and the bone structure is familiar, these are not problems.

4. To understand the difference between cortical bone and cancellous bone nail, we should know what cortical bone is and what cancellous bone is. If we are familiar with it, it will be difficult to solve it.

There is no special book for orthopedic consumables, but our company will have some information. Many of them are non-medical majors. It is a little difficult to learn at first, but you can solve the problem by looking at anatomy. Orthopedic implants are designed according to anatomy, so it is not difficult to read them well.

Finally, I think it's so difficult to write. Give me some points. I've been working on joints and spine, so you can ask questions. Thank you!
