Abstract
A syrinx involves cystic dilation of the central canal of the spinal cord due to the accumulation of cerebrospinal fluid and often results in a neurological deficit. While treatment options vary, surgical management is often utilized and requires an open durotomy. A 70-year-old female presented with one year of progressive low back pain with associated leg numbness, urinary incontinence, bilateral foot drop, and imbalance resulting in multiple falls. MRI revealed a terminal syrinx at the level of the conus medullaris. She underwent an uncomplicated T12-L1 laminectomy for syrinx fenestration and syringo-subarachnoid shunt placement, resulting in improved bladder/bowel function, strength, sensation, and ambulation. The necessary midline durotomy was closed with a running 6-0 prolene suture fastened at the start and end of the suture line with the novel use of the COR-KNOT MICRO(TM) device (LSI Solutions, Victor, New York, US). We present the successful surgical management of a progressively symptomatic terminal syrinx using a syringo-subarachnoid shunt and the novel use of the COR-KNOT MICRO(TM) titanium fastener device for dural closure. Earlier shunting should be considered in the disease course of terminal syrinx, and the successful novel use of a titanium fastener on the dura warrants further investigation.
