Abstract
Objective: To investigate the clinical efficacy of the Zero-profile fusion cage (Zero-P) combined with Traditional Chinese Medicine-directed drug delivery technique in the treatment of cervical spondylotic myelopathy, and to assess its impact on potential postoperative complications. Methods: 13 patients with cervical spondylotic myelopathy were selected from January 2022 to October 2023. The intraoperative bleeding volume, operation duration, and hospitalization days were recorded, the incidence and improvement of postoperative complications were observed, and the pain index and cervical function index were analyzed, including Visual Analogue Scale (VAS) score, Japanese Orthopedic Association (JOA) score, Neck Disability Index (NDI) index, etc. Results: The operation duration of patients was 65–110 (81.92 ± 13.47) min; mean intraoperative blood loss was 12.30 ± 7.80 ml, and mean postoperative hospital days were 9.62 ± 3.52 days. All patients in this group were followed up over 3 months after surgery, and the study found that the VAS, JOA, and NDI scores improved significantly compared with the preoperative difference (P < 0.01); and the VAS, JOA, and NDI scores 1 month postoperative improved significantly compared with 1 week postoperative (P < 0.01). In addition, the incidence of postoperative complications of the Zero-P system was low, with no incision infection, implant rejection, fracture, displacement, cerebrospinal fluid leakage, recurrent laryngeal nerve injury, and laryngeal edema; one patient had mild dysphagia (7.69%) and nine patients had throat dryness and discomfort (69.23%), which completely disappeared after 1 week of TCM-directed drug treatment and symptomatic treatment. Conclusion: Zero-P system interbody fusion has a significant effect on cervical spondylotic myelopathy, with a low incidence of postoperative complications and fast improvement speed, which can effectively enhance the impact of surgery on cervical spondylotic myelopathy patients, thus it is worthy of application and promotion.
