Have you been told you need fusion surgery for your neck?

You may be eligible to participate in a clinical study.

This clinical study is evaluating whether the Posterior Cervical Stabilization System (“PCSS”) improves fusion rates for cervical fusion patients when used as part of Circumferential Cervical Fusion.

Study Hypothesis: Patients who receive circumferential fusion with PCSS will have a higher rate of fusion and fewer surgical failures.

Innovative, Investigational Treatment Technology

The Posterior Cervical Stabilization System (“PCSS Device”) is a small titanium implant that is surgically placed in the facet joints on the back side of the neck. PCSS, as part of posterior cervical fusion (PCF, see image), is designed to be used with an ACDF to immobilize and stabilize the spine, which may improve fusion rates.

Prior to placing the implants into the facet joints, the doctor will prepare the target joints with PMT surgical instruments and then deliver PCSS through a small tube to minimize muscle and tissue damage. The PMT surgical instruments are commercially available and indicated for posterior cervical fusion in patients with degenerative disc disease.

What clinical information is already available for PCSS?

PCSS is an investigational device. Providence Medical Technology, the company that designed PCSS, conducted a clinical study in the Philippines using a similar device that was also placed into the facet joints.

This study demonstrated:9,10

  • A decrease in pain
  • Lower Neck Disability Index (NDI) scores — a quality of life scale
  • High fusion rate

In addition, surgeons in the U.S. have used the PCSS and similar devices in their patients with favorable outcomes and a low reported device-related complication rate of 3.4%.11

In a biomechanical study, the combination of ACDF (anterior fusion) and a PCF (posterior fusion) using PCSS significantly increased spinal stability versus ACDF alone.12

Prior to deciding whether to participate in the study, please discuss the risks and benefits of PCSS and the study with your doctor.

Official Study Name

Safety and Effectiveness of Posterior Cervical Stabilization System (PCSS) as an adjunct to posterior cervical fusion (PCF), when used in combination with ACDF in the treatment of multi-level cervical degenerative disease. (“FUSE Study”)
