Objective: The follow-up-study was part of a data-collection of multiple sites internationally for an IDE - study in the United States to determine the safety and efficacy of the implant.
Methods: From February 2002 to November 2004 240 patients were treated at our hospital with the Coflex interspinous device. 200 patients were evaluated (83%). The main indication for the device was in 152 patients spinal stenosis (76%).
Results: Data evaluation shows in 86% an improvement of severe low back pain leading to an significant improvement of their walking distance. 83% of patients had a walking distance preoperative <1000 m, 88% of patients postoperative >1000 m. We found a high rate of patient satisfaction: 91% satisfied or very satisfied, 93% would have surgery again. 6 complications have been reported of which 4 complications lead to an implant removal (2%).
Conclusions: Coflex allows for dynamic stabilisation after neural decompression significantly reducing back pain without fusion. The treatment of spinal canal stenosis with Coflex is save and effective.
