Secondary stenosis of the same level of the spinal canal and bilateral intervertebral foramina is a result of imaging and is considered to be secondary spinal stenosis, which is mainly due to a variety of factors such as trauma, degenerative changes, medically induced injuries, and other pathologies. 1. Trauma: When the spinal canal encounters trauma, the bony and fibrous structure of the spinal canal may be damaged, and the fracture mass may project into the spinal canal, which leads to secondary spinal stenosis, so that the patient will show secondary stenosis of the same level of the spinal canal and bilateral foramina on the imaging examination. 2. Degenerative changes: secondary spinal stenosis can also be caused by age, occupation and other factors that lead to degenerative changes in the intervertebral disc, which will lead to a decrease in the effective volume of the spinal canal, thus secondary spinal stenosis occurs. 3. Medical injury: Secondary spinal stenosis can also be caused by surgical trauma, surgical scarring, and other surgical procedures that result in excessive laminectomy, causing instability of the vertebral body, which can lead to secondary spinal stenosis. 4. Other lesions:If the patient suffers from infectious diseases, tumors and other diseases, it may also lead to secondary spinal stenosis. Patients with secondary stenosis of the same level of the spinal canal and bilateral intervertebral foramina on imaging should consult a doctor in time and follow the doctor’s instructions.
