Background:
Slack or kinking of the spinal cord due to compression lesions is rare.
Case Description:
A 73-year-old woman sustained a vertebral compression fracture at L1 following a fall. Progressive vertebral collapse caused upward displacement of the conus medullaris and slackening of the spinal cord, leading to bilateral thigh pain and myelopathic symptoms. Decompression and fixation surgery were performed. Due to osteoporosis, screws were inserted through the endplates and augmented with bone cement to prevent implant failure. Postoperatively, the patient's symptoms resolved, and her neurological function improved.
Conclusion:
When the spinal cord becomes slack due to compression at the thoracolumbar junction, symptoms of both cauda equina tension and myelopathy may develop. Surgical decompression and fixation can restore the spinal cord morphology and improve neurological function.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
