Coflex Implant For Spinal Stenosis

The coflex® Interlaminar Technology is an Interlaminar Stabilization  device indicated for use in one or two level lumbar stenosis from L1-L5 in skeletally mature patients with at least moderate impairment in function, who experience relief in flexion from their symptoms of leg/buttocks/groin pain, with or without back …

The Coflex device was initially marketed as the “interspinous U” in France  but its correct designation is “interlaminar” device. It is made of a titanium alloy and designed to fit between two adjacent spinous processes in the lumbar spine, appearing as a U-shape on a lateral radiograph. There are clips on the superior and inferior aspects of the “U” which anchor on both sides of the superior and inferior spinous processes. The clips are staggered such that the superior clips are more anterior, which allow for consecutive levels to be implanted. The Coflex is also slightly different from other ISS in that it is intended to be implanted after a decompression of the canal has been performed at the affected levels. The device provides dynamic stabilization (it compresses on lumbar extension but also permits flexion) while providing relative distraction of the posterior elements throughout the range of motion.

coflexSpinal stenosis is a medical condition that narrows the cervical or lumbar spinal canal, which in turn compresses the nerve roots that run through it. It causes back, leg and neck pain, numbness in the buttocks, thighs or calves, pain that worsens with walking or exercise, leg weakness, and difficulty with walking and balance. Stenosis is typically treated with anti-inflammatory medication and pain relievers, and physical therapy to aid with posture and walking. Coflex impant Surgery is recommended when other measures to control spinal stenosis fail.

The Coflex implant is implanted within the spinal canal, with the application of a mallet ensuring that it is firmly implanted into the bone. On either side of the Coflex implant are metal “wings”. These wings are often crimped against the bone in order to ensure sufficient contact with the bone. The precise placement of the Coflex implant provides the spine with stabilization and proper height of the segment where the implant has been placed. The placement of the Coflex implant also ensures that irritated nerves will not be irritated again.
