Prospective Study of Fusion Rates Using Spira-C Device for Anterior Cervical Discectomy and Fusion Surgery — ACDF  

Cervical Radiculopathy Clinical Trial

Official title: A Prospective Clinical Pilot Study Of Fusion Rates Using Spira™-C Titanium 3-D Printed Interbody Device For Anterior Cervical Discectomy And Fusion

Status Terminated

Clinical Trial Summary

The objective of this study is to perform a prospective, single-arm clinical evaluation utilizing the Spira™-C 3-D printed titanium interbody device for treatment of degenerative disc disease and spinal stenosis of the cervical spine to evaluate fusion status and patient reported outcomes. The primary objective is fusion status or bony healing within the device. Patient reported outcomes, i.e. pain, function, and quality of life will also be measured postoperatively.

Clinical Trial Description

This is a post-market, single-arm, prospective clinical study to evaluate fusion status and patient reported outcomes using the Spira-C titanium interbody cage for degenerative disc disease where single-level ACDF surgery is indicated. The treatment group will consist of 40 subjects treated with the Spira™-C interbody device at one level. Patients with a diagnosis of cervical degenerative disc disease and/or spinal stenosis, radiculopathy or myelopathy and planning to undergo a 1-level ACDF surgery between C3-C7 will be screened and consented, if eligibility requirements are met. Once the subject has been enrolled and the surgery has taken place; data will be collected regarding the surgical details will be collected. Subjects will be followed up postoperatively at 6-weeks, 3-months, 6-months, and 12-months as per standard of care, at the private practice or clinic. Subjects will be asked to complete questionnaires regarding pain, function, and quality of life before and after surgery during the postoperative follow-up visits. Radiographic assessments will be performed at all postoperative visits; fusion status will be measured using cervical x-rays and CT scan at 12 months. Radiographs will also be utilized to assess for device-related complications, including implant failure. Any clinically significant complications related to the device will be recorded as an adverse event. This study design reflects the current standard of care for cervical degenerative disc disease and spinal stenosis with symptoms of radiculopathy or myelopathy. Data collected from subjects treated with the Spira™-C Interbody Device will be compared to historical data based on literature review of polyetheretherketone (PEEK) cage fusion rates and patient reported outcomes. Anterior cervical discectomy and fusion using an interbody device with plate and screw fixation is the treatment of choice after conservative therapies (non-surgical, i.e., physical therapy, epidural steroid injections, pain medications) have been exhausted. ;
