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.
