OBJECTIVE: Anterior cervical corpectomy and fusion (ACCF) is employed in patients with localized cervical spinal stenosis (CSS). However, there are some disadvantages such as subsidence of the titanium mesh cage, slow fusion rates, breakage of the plate and screws, and donor-site complications. For patients with small posterior osteophytes, ossified or hypertrophy of the posterior longitudinal ligaments or ligamentum flavum, the range of decompression from the classic anterior cervical discectomy and fusion (ACDF) cannot meet the clinical requirements. However, employing ACCF is controversial. Therefore, it is necessary to seek a novel, safe and effective surgery that can combine the strengths of ACDF and ACCF. Our objective was to describe a novel anterior approach cervical surgery and investigate its clinical outcomes on segmental CSS at the C4-C6 levels 6 months postoperatively.
METHODS: A novel anterior cervical X-shape-corpectomy and fusion (ACXF) was performed to correct the CSS.
RESULTS: The patient's neurologic function and myodynamia of the extremities were improved significantly 3 and 6 months after surgery with good bony fusion. Neck pain also was relieved. Immediately postoperative and after 6-month images indicated no significant spinal stenosis. The patient's cervical curvature was improved after surgery without significant implant subsidence or loss of adjacent intervertebral height. There were no postoperative complications.
CONCLUSIONS: ACXF may be a safe and effective procedure for segmental CSS and an alternative for ACCF, as it has a wide operative field of view, sufficient decompression range, excellent transverse vertebral bony fusion, less internal fixation-related complications, and graft subsidence and no donor-site complications.
