Purpose Cervical disc herniation is a common pathology. It can be treated by different surgical procedures. We aimed to list and analyzed every available surgical option. We focused on the comparison between anterior cervical decompression and fusion and cervical disc arthroplasty. Results The anterior approach is the most commonly used to achieve decompression and fusion by the mean of autograft or cage that could also be combined with anterior plating. Anterior procedures without fusion have shown good outcomes but are limited by post-operative cervicalgia and kyphotic events. Posterior cervical foraminotomy achieved good outcomes but is not appropriate in a case of a central hernia or ossification of the posterior ligament. Cervical disc arthroplasty is described to decrease the rate of adjacent segment degeneration. It became very popular during the last decades with numerous studies with different implant device showing encouraging results but it has not proved its superiority to anterior cervical decompression and fusion. Anterior bone loss and heterotopic ossification are still to be investigated. Conclusion Anterior cervical decompression and fusion remain the gold standard for surgical treatment of cervical disc herniation.
In a cohort of 20 patients with 15-year clinical and radiological follow-up, the Bryan CTDR has demonstrated a sustained clinical improvement and implant mobility over time, despite a moderate progression of degenerative processes at the prosthetic and adjacent levels.
Introduction: Management of surgical site infections (SSI) after
instrumented spinal surgery remains controversial. The debridement-irrigation, antibiotic
therapy and implant retention protocol (DAIR protocol) is safe and effective to treat deep
SSI occurring within the 3 months after instrumented spinal surgery.Methods: This retrospective study describes the outcomes of patients treated
over a period of 42 months for deep SSI after instrumented spinal surgery according to a
modified DAIR protocol.Results: Among 1694 instrumented surgical procedures, deep SSI occurred in
46 patients (2.7%): 41 patients (89%) experienced early SSI (< 1 month), 3 (7%)
delayed SSI (from 1 to 3 months), and 2 (4%) late SSI (> 3months). A total of 37
patients had a minimum 1 year of follow-up; among these the modified DAIR protocol was
effective in 28 patients (76%) and failed (need for new surgery for persistent signs of
SSI beyond 7 days) in 9 patients (24%). Early second-look surgery (≤ 7days) for
iterative debridement was performed in 3 patients, who were included in the cured group.
Among the 9 patients in whom the modified DAIR protocol failed, none had early second-look
surgery; 3 (33%) recovered and were cured at 1 year follow-up, and 6 (66%) relapsed.
Overall, among patients with SSI and a minimum 1 year follow-up, the modified DAIR
protocol led to healing in 31/37 (84%) patients.Conclusions: The present study supports the effectiveness of a modified DAIR
protocol in deep SSI occurring within the 3 months after instrumented spinal surgery. An
early second-look surgery for iterative debridement could increase the success rate of
this treatment.
