A 2-and-5-year evaluation of clinical outcomes in the treatment of degenerative spinal stenosis with concomitant low back pain by decompression with or without additional stabilization using the coflex? ? Interlaminar Technology for FDA Actual Conditions of Use Study.
The first objective addresses coflex? performance in actual conditions of use settings at two years and at five years relative to pivotal trial device performance. The second objective compares coflex? performance in actual conditions of use settings to decompression alone using data from the completed randomized ESCADA study comparing coflex? to decompression alone.
