The study shows 44.1% Device Specific Complications with Vertiflex Superion plus 21.1% spinous process fractures.
The purpose of this study was to compare the short-term complications of the Vertiflex Superion interspinous spacer (SISS) with laminectomy or laminotomy and highlight device-specific long-term outcomes with SISS.
The study evaluated 189 SISS patients compared with 378 matched controls who underwent primary lumbar spine laminectomy or laminotomy. Results showed a total of 44.4% of patients in the SISS group experienced device-specific complications with 11.1% of patients experiencing device malfunction. A total of 21.1% experienced a spinous process fracture with 20.1% requiring device explantation, and 24.3% requiring subsequent spine surgery. The article concluded that Vertiflex Superion patients will likely need additional procedures with substantial cost to the healthcare system. [1]
