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 Type
OBSERVATIONAL
Enrollment
33
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.
