The invention relates to an airfoil type lumbar-isthmus internal fixator, which belongs to the field of medical devices, and is suitable to be applied to lumbar spondylolysis surgeries. The airfoil type lumbar-isthmus internal fixator is composed of an airfoil (1) and a fixator body (2); and the airfoil type lumbar-isthmus internal fixator is characterized in that: the airfoil (1) is in the shape of an arc sheet, and the fixator body (2) is of a U-shaped structure. An appropriate internal fixator is selected to carry out a surgery according to the diagnosis: firstly, the depth and azimuth of the surgery are determined, and a surgical opening is operated; and then, an internal fixator is implanted in the surgical opening and fixed to a surgery-required position, thereby achieving the purpose of the surgery.
Description
technical field [0001] The invention relates to an airfoil-shaped lumbar isthmus internal fixer, which belongs to the field of medical equipment and is suitable for lumbar isthmus surgery. Background technique [0002] Lumbar spondylolysis is a discontinuous bone defect in the isthmus between the upper and lower articular processes of the lumbar spine on one or both sides, also known as spondylolysis or nonunion of the isthmus. [0003] Lumbar spondylolisthesis is one of the common causes of low back pain, and it is also an important cause of spondylolisthesis. The basic lesion is the fracture of the isthmus bone, the loss of the ability of the vertebral facet joints to resist shear stress, the instability of the lumbar spine, and finally the loss of the vertebral body. Slip forward. The main symptom is lumbago and leg pain. The location and nature of the pain are different. It can be continuous or intermittent. There are also those who only have pain when they are overwork...
