The occupational impact of single-level cervical disc arthroplasty in an active duty military population

Abstract

Introduction: Degenerative cervical disease is a common condition affecting the general population. This process can have a detrimental effect on operational readiness and is a concern for military spine surgeons. Cervical disc arthroplasty (CDA) is a relatively new surgical treatment for cervical disease. Objective: To evaluate the occupational impact of CDA used to treat single-level cervical disease in a high demand military population. Methods: Case series of 34 patients with prospective follow-up who had undergone single-level CDA at our institution. Results: Average follow-up was 21.4 months. Noncommissioned officer was the most common rank. C5-C6 was the most common operated level. 30/34 (88.2%) returned to active duty service. 4/34 (11.8%) went on to medical evaluation board for separation from active duty service. 28/30 (93.3%) returned to duty patients vs. 2/4 (50%) medical board patients reported relief with surgery. Average return to duty time was 8.5 weeks. All patients who returned to duty were able to maintain preoperative military occupational specialty. 8/30 (26.7%) were able to deploy postoperatively. Conclusion: CDA has the potential to allow return to high demand preoperative occupational activities in active duty military patients with single-level cervical disease.
