Most patients will have improvement or stabilization of preoperative symptoms. Twelve of the authors’ 13 patients underwent surgery. The average follow-up at that time was 2.2 years. Three patients presented neurologically normal. The follow-up publication on TCS and the normally positioned conus compared this subgroup to patients with TCS and a low-lying conus medullaris, which consisted of 60 patients (36).
- Strength: 75%t of patients with lower extremity weakness improved with surgery (36).
- Urinary and bowel function: For urinary complaints, two patients had normal urinary control at follow-up, one patient had improved control, and one patient with neurogenic bladder had no postoperative change. Of patients presenting with bowel complaints, all three had cessation of complaints at follow-up (36).
- Pain: Two patients presented with back pain that resolved after surgery. The one patient who did not undergo surgery presented with low back pain and radicular leg pain that was improved 6 months later (36).
