Introduction:
A retrospective study was performed in patients with a lumbar disc herniation treated with the Coflex interspinous U implant.
Material And Methods:
A total of 200 patients who underwent surgery for lumbar disc herniation were evaluated; 100 were assigned to the Coflex group and 100 underwent microsurgery only. A clinical assessment and serial X-rays were performed. All patients were followed-up for 5 years.
Results:
Our study reveals that the use of the device was more effective (statistically significant) for delayed instability than the surgical technique by itself (p < 0.01).
Conclusion:
The use of this device delays vertebral collapse and therefore the instability of the operated segment.
