Anterior cervical V-Slot decompression and fusion for long-segment cervical ossification of the posterior longitudinal ligament: a follow-up study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cervical ossification of the posterior longitudinal ligament (OPLL) causes spinal cord compression due to spinal canal stenosis. Traditional anterior approaches such as anterior cervical discectomy and fusion (ACDF) and anterior cervical corpectomy and fusion (ACCF) have limitations, including restricted decompression range, extensive vertebral resection trauma, or insufficient stability. This study aimed to evaluate the efficacy and safety of a novel surgical technique-Anterior Cervical V-Slot Decompression and Fusion (ACVDF)-for treating long-segment OPLL. A retrospective analysis was conducted on 30 patients with multilevel OPLL who underwent ACVDF between December 2021 and March 2024. A curved grinding drill was used to precisely remove portion of the vertebral body and ossified tissue (≤ 50% of the sagittal diameter) through the V-shaped distracted intervertebral space, achieving direct decompression of long-segment OPLL During surgery. Postoperative follow-up 14.70 ± 1.62 months (12-18 months). Clinical outcomes were assessed using the Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, and imaging methods such as CT and MRI. All 30 patients successfully completed the surgery, with a mean operative time of 143.17 ± 10.96 min and intraoperative blood loss of 177.67 ± 49.45 ml. At the final follow-up, the JOA score improved from 8.50 ± 1.96 to 14.67 ± 0.71 (P < 0.05), with an excellent and good rate of 90.00%. The VAS score decreased from 6.53 ± 1.53 to 1.30 ± 0.79 (P < 0.05). The spinal canal occupancy rate decreased from 42.13 to 10.61% (P < 0.05). The Height of the fused segments was 62.70 ± 13.58 mm at 1 week postoperatively and increased to 62.94 ± 13.99 mm at the final follow-up (P > 0.05). Cervical range of motion (ROM) decreased from 51.57 ± 8.96° preoperatively to 33.07 ± 6.18° at the final follow-up (P < 0.05). The fusion rate reached 100% at the final follow-up. No complications such as dural tears or spinal cord injuries occurred during surgery. ACVDF can achieve direct decompression of long-segment OPLL while preserving anterior column structures, maintaining cervical stability, and getting favorable clinical outcomes. This technique provides a new safe and effective treatment option for long-segment OPLL.
