Early results after ProDisc-C cervical disc replacement

Abstract

<jats:p content-type="fine-print"><jats:italic>Object.</jats:italic> Cervical anterior decompression and total-disc replacement is currently being investigated as an alternative treatment in patients with symptomatic intervertebral cervical spondylosis with and without radiculopathy. The authors prospectively investigated the safety and efficacy of using the ProDisc-C disc for cervical arthroplasty in the treatment of symptomatic cervical spondylosis.</jats:p> <jats:p content-type="fine-print"><jats:italic>Methods.</jats:italic> Sixteen patients in whom a diagnosis of symptomatic cervical spondylosis had been established were prospectively treated with complete anterior cervical discectomy and ProDisc-C cervical disc arthroplasty. Overall 12 single- and four two-level procedures were performed (20 prostheses). Patients underwent pre- and multiple postoperative assessments (3 and 6 weeks and 3, 6, and 12 months).</jats:p> <jats:p content-type="fine-print">The median age of all patients was 50 years (range 32–60 years). Levels of surgery included seven C5–6, six C6–7, and three C4–5. Neck and arm pain as well as disability scores were significantly improved by 3 months and remained significantly improved at 1 year. No additional fusion surgeries were necessary at the affected or unaffected levels. Radiography revealed an affected disc motion from 4 to 12°. No surgery- or device-related complications were documented.</jats:p> <jats:p content-type="fine-print"><jats:italic>Conclusions.</jats:italic> Analysis of preliminary results involving ProDisc-C arthroplasty indicates significant improvement in pain and functional outcome scores. No spontaneous fusions at the level of surgery or at adjacent levels were noted. Long-term follow-up studies will be necessary before more definitive treatment recommendations can be formulated.</jats:p>

Local and global subaxial cervical spine biomechanics after single-level fusion or cervical arthroplasty

“…The complications led to changes in the design that have demonstrated more favorable clinical results [33]. Similar clinical results have been reported in trials using several other designs, including the Bryan cervical disc [8,16], porous coated motion (PCM) prosthesis [26], Frenchay artificial cervical joint [33,34], Prestige II implant [27], and the ProDisc-C [4].…”

Fusion versus Bryan Cervical Disc in two-level cervical disc disease: a prospective, randomised study

“…However, there are clues that ACDF may result in progressive degeneration of the adjacent segments [10,15]. To avoid this, there have been numerous attempts to develop and use artificial cervical discs [3,9]. Compared with cervical fusion, disc replacement offers the theoretical biomechanical advantage of preservation of motion at the operative level which reduces stresses at the adjacent level [6].…”

Investigation of pain, disability level and quality of life in patients with cervical disc prosthesis and peek cage

“…Bertagnoli ve ark. [10] ise servikal disk protezi uyguladıkları hastalarında cerrahi sonrasında ağrıda ve fonksiyonel katı-lımda ameliyat sonrası 6. ve 12. ay sonrasında anlamlı gelişmeler olduğunu açıklamışlardır. Yapılan başka bir çalışmada, servikal anterior "cage" ve servikal protez uygulanan 74 hastayı 24 ay takip etmişler ve sonuçta fonksiyonel hareketliliği sağlamak için "cage" ve füz-yon yerine protezin daha etkili bir yöntem olduğunu belirtmişlerdir.…”
