We performed a retrospective analysis of all cases of lumbo-sacral or sacral metastases presenting with compression of the cauda equina who underwent urgent surgery at our institution. Our objective was to report our experience on the clinical presentation, management and finally the surgical outcome of this cohort of patients. ⋯ Surgical intervention for MSCC involving the lumbo-sacral junction or sacral spine has a high but acceptable complication rate (6/20, 30 %), and can be important in restoring/preserving neurological function, assisting with ambulatory function and allowing patients to return to their previous residence.

To examine disc degeneration at levels adjacent and next adjacent to the fractured vertebra and to analyses, if the disc degeneration is determined by the endplate fracture. Thoracolumbar burst fracture is one of the most common spinal injuries. The diagnostic (clinical and imaging) approach and treatment of a fractured vertebra is well established; however, some controversy remains. The associated disc degeneration is less well known after 9-12 months of the short segment pedicle screw fixations. There is a major controversy whether spinal trauma with vertebral endplate fractures can result in posttraumatic disc degeneration. No study to date, however, has assessed disc degeneration of the AO type A3 thoracolumbar fractures without neurologic deficits after pedicle screw fixations. ⋯ Disc degeneration usually occurs at level adjacent to the fractured endplate of thoracolumbar burst fractures. Endplate fracture is strongly associated with disc degeneration. No correlation between fixation level and disc degeneration is seen in this study.
