Clinical and radiological features of hybrid surgery in multilevel cervical degenerative disc disease.

2015

Purpose: Although several studies have established the safety and efficacy of cervical disc arthroplasty (CDA) as compared to anterior cervical discectomy and fusion (ACDF), few studies have investigated the role of hybrid surgery (HS) that incorporates ACDF and CDA techniques in multilevel cervical degenerative disc disease (MLCDDD). Methods: This prospective study enrolled patients with MLCDDD who underwent HS. Twenty consecutive patients who underwent HS were compared with patients who underwent ACDF and CDA at the same level of surgery. Patients were followed up for more than 2 years. Intraoperative parameters, clinical features and outcome scores were recorded. Radiological assessments…

ADDISC lumbar disc prosthesis: Analytical and FEA testing of novel implants

2023

The intact intervertebral disc is a six-freedom degree elastic deformation structure with shock absorption. 'Ball-and-socket' TDR do not reproduce these properties inducing zygapophyseal joint overload. Elastomeric TDRs reproduce better normal disc kinematics, but repeated core deformation causes its degeneration. We aimed to create a new TDR (ADDISC) reproducing healthy disc features. We designed TDR, analyzed (Finite Element Analysis), and measured every 500,000 cycles for 10 million cycles of the flexion-extension, lateral bending, and axial rotation cyclic compression bench-testing. In the inlay case, we weighted it and measured its deformation. ADDISC has two semi-spherical articular s…
