Abstract
OBJECTIVE Spondylodiscitis refers to infection of the intervertebral disk and neighboring structures. Outcomes based on instrumentation type are not well reported in the literature, but are important in establishing guidelines for surgical management of spondylodiscitis. This study aims to clarify the effect of instrumentation material selection on clinical and radiographic outcomes in patients with spondylodiscitis. METHODS Studies that evaluated the use of polyetheretherketone (PEEK), titanium, allograft, and/or autologous bone grafts for spondylodiscitis were identified in the literature. Radiographic and clinical data were analyzed using a meta-analysis of proportions, with estimated risk and confidence intervals reported for our primary study outcomes. RESULTS Thirty-two retrospective studies totaling 1088 patients undergoing surgical management of spondylodiscitis with PEEK, TTN, allograft, and autologous bone graft instrumentation were included. There were no differences in fusion rates (p-interaction = 0.55) with rates of fusion of 93.4% with TTN, 98.6% with allograft, 84.2% with autologous bone graft, and 93.9% with PEEK. There were no differences in screw loosening (p-interaction = 0.52) with rates of 0.33% with TTN, 0% with allograft, 1.3% with autologous bone graft, and 8.2% with PEEK. There were no differences in reoperation (p-interaction = 0.59) with rates of 2.64% with TTN, 0% with allograft, 1.69% with autologous bone graft, and 3.3% with PEEK. CONCLUSIONS This meta-analysis demonstrates that the choice of instrumentation type in the surgical management of spondylodiscitis resulted in no significant differences in rate of radiographic fusion, screw loosening, or reoperation. Future comparative studies to optimize guidelines for the management of spondylodiscitis are needed.

Posterior Decompression and Fusion for Cervical Spondylodiscitis due to Osteoradionecrosis after Head-and-Neck Cancer Radiotherapy: Two Case Reports. J Orthop Case Rep 2024; 14:11-16.

Abstract
Introduction Cervical spondylodiscitis due to osteoradionecrosis (ORN) after head-and-neck cancer radiotherapy is a severe complication. However, there are few reports on the surgical treatment of this condition. Case Report We report two cases of cervical spondylodiscitis due to ORN, which were successfully treated with posterior decompression and fusion. The first case was in a 73-year-old male patient with spondylodiscitis at C3-C5, due to ORN. A posterior fusion of the spine (C2-T1) was performed, and a biopsy was conducted at a site separate from the incision for fusion. The second case was in a 76-year-old female patient with spondylodiscitis due to C4-C7 ORN. Cervical posterior decompression and fusion (C2-Th2) were performed, and decompression (C5-6) was conducted through an incision separate from that for the fusion.An anterior approach was avoided in both cases because of radiation-induced tissue changes. For these two patients with cervical spondylodiscitis due to ORN, surgery resulted in an improvement of infection and neurological deficits by posterior spinal fusion, isolation from decompression or biopsy of the infected area, and antibiotic treatment. Conclusion Posterior decompression and fusion are effective for spondylodiscitis in the cervical spine after head-and-neck radiotherapy, treating both infection and neurological deficits. Spinal fusion that avoids the level of the infected vertebral body and decompression from separate skin incision sites may prevent the spread of infection. An anterior approach should be avoided because the risk of esophageal perforation and posterior pharyngeal wall defects is high.

Abstract
BACKGROUND Surgical treatment of vertebral osteomyelitis, discitis, and epidural abscesses is indicated in the setting of failure of antibiotic therapy, neurological deficits, epidural abscess, or spinal instability/deformity. Historically, surgical treatment mandated aggressive debridement and spinal stabilization. However, there is growing evidence that direct debridement may not be necessary and may contribute to morbidity. The purpose of this study was to evaluate the efficacy of posterior instrumentation without debridement in treating spinal infections. METHODS A retrospective medical record review was performed to identify patients treated with posterior instrumentation for spontaneous spinal infections. Success of treatment was determined based on postoperative ambulatory status, surgical complications, and need for revision surgery. RESULTS Twenty-seven patients treated with posterior-only long-segmented rigid fixation without formal debridement of infected material were included. The most common indications for surgical intervention included spinal instability (67%), neurologic compromise (67%), and failure of prolonged antibiotic treatment (63%). There were no recurrent deep infections in 21 of 22 patients who had long-term follow-up. Four patients required revision surgery, and 3 additional patients requested elective hardware removal. Postoperatively, 70% were ambulatory with no assistive devices postoperatively. CONCLUSIONS Vertebral osteomyelitis/discitis are challenging medical problems. Single-stage long-segment fusion without formal debridement combined with antibiotics is effective in the management of spontaneous spinal infections. CLINICAL RELEVANCE The present study suggests that acute instrumentation without anterior debridement is associated with a resolution of infection and improvements in neurologic deficits in patient with spontaneous spine infections.
