Determination of the in vivo posterior loading environment of the Coflex interlaminar-interspinous implant.

Background Context: The in vivo loading environment of load-bearing implants is generally largely unknown. Loads are typically approximated from cadaver tests or biomechanical calculations for the preclinical assessment of a device's safety and efficacy.

Purpose: To determine the actual in vivo loading environment of an elastic interlaminar-interspinous implant (Coflex).

Survivorship of coflex Interlaminar-Interspinous Implant.

Background: The purpose of this study was to determine the indications for implantation of the coflex device (Paradigm Spine, LLC, New York, New York), assess long-term complications, and evaluate the long-term clinical outcomes of patients.

Methods: A total of 127 patients underwent placement of a coflex implant for various indications by one orthopaedic spine surgeon. The mean follow-up was 6.
