BACKGROUND: Posterior cervical fusion with @entity3799 ( @entity3799 ) is a novel allograft technology offering the potential to provide indirect neuroforaminal decompression while simultaneously enhancing fusion by placing the allograft in compression. OBJECTIVE: To analyze the clinical and radiological outcomes after posterior cervical fusion with @entity3799 in @entity1 with symptomatic anterior cervical @entity1516 . METHODS: Medical records of @entity1 who underwent posterior cervical fusion with @entity3799 for symptomatic @entity1516 after anterior cervical diskectomy and fusion were reviewed. Standardized outcome measures such as @entity227 ( @entity227 ) score for neck and arm @entity158 , @entity717 ( @entity717 ), and upright lateral cervical radiographs were reviewed. RESULTS: There were 19 @entity1 with symptomatic cervical @entity1516 . Preoperative symptoms included @entity4048 . The average follow-up was 20 months (range, 12-56 months). There was improvement in @entity227 score for neck @entity158 (P < .004), radicular arm @entity158 (P < .007), and @entity717 score (P < .06) after surgery, with 83%, 72%, and 67% of @entity1 showing improvement in their @entity227 neck @entity158 , @entity227 arm @entity158 , and @entity717 scores, respectively. Fusion rate was high, with fusion occurring at all levels treated for @entity1516 . There was a small improvement in cervical @entity1515 (mean difference, 2    5.17  ; P = .09) and slight worsening of C2-7 sagittal vertical axis after surgery (mean difference, 1.89    7.87 mm; P = .43). CONCLUSION: @entity3799 provides an important fusion technique, allowing placement of an allograft in compression for posterior cervical fusion in @entity1 with anterior cervical @entity1516 . Although there was improvement in clinical outcome measures after surgery, placement of @entity3799 had no clinically significant impact on cervical @entity1605 .
