Brief Summary
Prostheses use subsequently became prevalent and a number of studies were conducted. However, prosthesis-associated heterotropic ossification (HO) in the segments with prostheses was reported in 2005, which disrupted mobility and caused fusion. In the present study, we aimed to investigate the clinical outcomes, HO incidence, and prosthesis mobility in the patients following the operative use of Alpha-D disc prosthesis as developed and used by the authors to treat cervical disk diseases.

Study Arms (1)
Alpha-D cervical disc prosthesis
Alpha-D cervical disc prosthesis was developed jointly by the Spine Center of Koç University Faculty of Medicine and Toledo University Bioengineering Department. It was designed as a single unit to ensure user-friendly administration for surgeons, and it was designed and manufactured to reproduce the movements of the normal cervical movement segment.

Eligibility Criteria
We included 33 patients with cervical disc hernia and associated radiculopathy upon radiological examination, who underwent a cervical discectomy and received cervical disc protheses (CDP; arthroplasty) with a single-level anterior discectomy.
You may qualify if:
- cervical disc hernia
- underwent cervical discectomy and received cervical disc prostheses
You may not qualify if:
- history of cervical surgery,
- kyphotic deformity,
- rheumatological or other systemic diseases,
- severe osteophytes caused by advanced degenerative disc disease
- severe spinal stenosis
