About this study
Official title: Anterior Cervical Disectomy And Fusion Using The Tritanium® C Anterior Cervical Cage For One Or Two-Levels: A Clinical And Radiographic Analysis Pilot Study
This is a prospective, single arm clinical study to evaluate fusion status and patient reported outcomes utilizing the Stryker Tritanium® C Anterior Cervical interbody device at one or two contiguous levels. Subjects that are recommended for surgical treatment of either a 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) between the levels of Cervical Spine 2 to Thoracic 1 (C2-T1) and diagnosed with degenerative disc disease will be screened for the study.
Read the detailed description
Degenerative disc disease of the cervical (neck) spine occurs when the discs between the vertebral bony bodies start to deteriorate or break down due to wear and tear over time. It is diagnosed as such once it is symptomatic and causes neck pain and radiculopathy (arm pain, weakness, and/or numbness). In order to correct the damaged disc and resolve radicular symptoms, anterior cervical discectomy and fusion surgery is commonly performed.
This is a prospective, single arm clinical study to evaluate fusion status and patient reported outcomes utilizing the Stryker Tritanium® C Anterior Cervical interbody device at one or two contiguous levels. Subjects that are recommended for surgical treatment of either a 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) between the levels of C2-T1 and diagnosed with degenerative disc disease will be screened for the study. Subjects will be followed up postoperatively per standard of care at 6-weeks, 3-monts, 6-months, 12-months and at 24-months at the private practice or hospital clinic. The primary end-point is Successful cervical spinal fusion as measured by dynamic (flexion and extension) x-rays and CT scan (using metal subtraction) at 12 months and as evidenced by the following three criteria: bony bridging, no presence of radiolucency, and no development of pseudoarthrosis at the treated cervical level.

Measured: 12 months postoperative
Secondary outcomes (7)

Measured: 24 months postoperative
Neck Disability Index for Pain and Function
Equal to or greater than a 15-point decrease in patient reported outcomes as measured by Neck Disability Index (0-100 point scale, 0 = least amount of disability, 100 = most severe disability) from baseline to 24-months.
Measured: 24 months postoperative
Short Form Health Survey-36 for Quality of Life
Equal to or greater than a 15-point improvement in patient reported outcomes as measured by SF-36 (0-100 point scale, 0=low favorable health state and 100 = most favorable health state) from baseline to 24-months
Measured: 24 months postoperative
Eating Assessment Tool - 10 for Dysphagia
Scores less than 3 or equal to baseline (scores 3 or higher may indicate problems with swallowing efficiently and safely) in patient reported outcomes as measured by Eating Assessment tool - 10 from baseline to 24-months.
Measured: 24 months postoperative
Neurological Deficit as defined by Cervical Spine Examination
Count of participants with new or worsening neurological cervical spine deficit as evaluated by cervical spine examination (motor and sensory) from baseline to 24-months
Measured: 24 months postoperative
Count of participants with development of pseudoarthrosis by month 12
Count of participants with development of pseudoarthrosis by month 24 as a result of device subsidence, migration, loosening or overall device failure.
Measured: 24 months postoperative
Count of participants with revision surgery by month 12
Count of participants with revision surgery by month 24 as a result of device subsidence, migration, loosening, or overall device failure.
Measured: 24 months postoperative
