Abstract

Introduction

Adults rarely present with tethered cord syndrome, and this review examines whether it is justifiable to perform surgical intervention in this group.

Methods

Between 2003 and 2017, we performed surgical intervention in 32 adults with tethered cord syndrome. The age range varied from 22 to 65 years. Twenty-six had pain, 20 had motor deficits, and 18 had sensory deficits, whereas 17 presented with sphincter disturbances. Three had undergone surgery for meningomyelocele as infants. Six patients had major spinal deformity in the shape of kyphosis or scoliosis. All patients underwent digital radiographs and MR scans of the whole spine. The oldest with a leaking open meningocele was 41 years old.

Results

The mean follow-up was 3.2 years. Twenty-one out of 26 patients presenting with pain had their VAS scores improve significantly; 14 had motor deficits which improved. However, sensory deficits got better in only 7 out of 18 patients, and sphincter improvement was documented (via urodynamics studies and bladder ultrasound) in only 4 out of 17 patients. In 15 cases, surgery was performed under neurophysiological monitoring, and overall improvement was documented in 11 of these patients compared with 7 of the remaining 17 patients. Surgery for spinal deformity was performed in 6 patients, and deformity correction as well as pain reduction was achieved in all.

Conclusion

Surgery leads to significant reduction of pain by untethering and in those with spinal deformity by correction of the same. Improvement in sensory changes and sphincter problems occurred in few patients. Neuromonitoring certainly has improved our results.
