Description

Technical Field

[0001] The invention relates to the technical field of postoperative fixation of osteoporotic spinal fractures, and in particular to a mobile fixation device for osteoporotic spinal fractures in the elderly. Background Art

[0002] As is known, osteoporosis can cause bones to become thinner and brittle, and become as loose and porous as sponges. Osteoporosis can easily lead to fractures. Osteoporosis mostly occurs in the elderly. Spinal fractures are a common disease in the elderly. After the elderly have undergone spinal fracture surgery, they still need external fixation to prevent the internal fixation at the spinal fracture and the spine hardened by bone cement from compressing the adjacent vertebrae and causing fractures. In summer, when patients wear external fixators, the external fixators are worn outside the clothes, which affects the appearance. The external fixators are worn inside the clothes. The external fixators are loose and cannot achieve the fixation effect. The external fixators are tight and can compress the patient's skin for a long time, which can cause the blood flow rate in the part where the patient contacts the external fixator to slow down. In addition, the part where the external fixator contacts the patient's skin is not ventilated. When the temperature is too high in summer, it is easy to sweat. Sweating in the part where the external fixator contacts the patient's skin will not only cause discomfort to the patient, but also the part where the external fixator contacts the patient's skin will be soaked in sweat for a long time, which can easily cause the part where the patient's skin contacts the external fixator to ulcerate. For this reason, we propose a mobile spinal fracture fixation device for osteoporosis in the elderly. Summary of the invention
