A bad cervical spine will not directly lead to a bad lumbar spine. However, in clinical work, we often encounter patients with bad cervical spine, degeneration and hyperplasia of the lumbar spine, instability of the lumbar spine, and even lumbar disc herniation. The indirect causes that may be involved are mainly seen in the following aspects: 1. Patients themselves have bone proliferation and degeneration, such as the elderly, and the overall spine is subject to strength loss and spinal instability, which leads to cervical spondylosis as well as lumbar disc herniation at the same time, mainly due to lesions in the overall spine. 2. Certain cervical spondylosis can lead to corresponding symptoms in the lower extremities, such as spinal cord-type cervical spondylosis, which can For example, spinal cord cervical spondylosis can lead to weakness in the lower limbs, unsteadiness in standing, and a feeling of stepping on cotton when walking. This situation will lead to increased load on the lumbar region, and also easily cause accidental injury to the lumbar region, which will lead to injury and strain on the lumbar region, and even lead to degeneration and hyperplasia of the lumbar spine, resulting in lumbar disc herniation.
