Meta Analysis
Timing of surgery in cauda equina syndrome with urinary retention: meta-analysis of observational studies.
The authors performed exploratory meta-analyses of observational cohort studies, evidence level III, examining whether earlier surgery makes a difference in outcome in terms of urinary function once cauda equina syndrome (CES) from a herniated lumbar disc has progressed to urinary retention (CESR). ⋯ This study supports early surgery for CES and indicates that CESR and CESI cases should not be analyzed together.

The authors report the first description since 1957 of a lumbar disc herniation as a cause of stump pain. Most amputees frequently experience stump pain or phantom pain. The pathophysiology of phantom pain is not clearly defined; however, there are well-defined reasons for stump pain such as infection, tissue necrosis, hematoma, wound breakdown, bone spur, neuroma, and so on. During the differential diagnosis, radiculopathy due to lumbar disc herniation must also be evaluated.
