Calcified thoracic disc herniations present a rare and challenging entity. Due to the close proximity to the spinal cord and relative narrowing of the spinal canal, the optimal approach remains a matter of debate. While the transthoracic approach is usually preferred, we adapted a new technique described in 2012: the transdural posterior approach. Our aim was to evaluate its benefits in patients with giant thoracic disc protrusions. We retrospectively reviewed all patients treated in our neurosurgical department from July 2012 to March 2020. Demographics, pre- and postoperative clinical status, and operative technique and complications were extracted and analyzed. In total, 12 patients underwent a posterior transdural resection of giant calcified thoracic hard discs between 2012 and 2020. All patients underwent a posterior decompression (laminectomy, hemilaminectomy, or laminoplasty). The median duration of surgery was 152 min. Transient postoperative neurological deterioration occurred in 4 patients, with complete recovery until time of discharge. No patient underwent a surgical revision. The transdural resection of giant calcified thoracic hard discs through a posterior approach provides an excellent decompression with sufficient visualization of the spinal cord and a satisfying postoperative outcome.

钙化胸椎间盘突出症是一种罕见且具有挑战性的实体。由于靠近脊髓且椎管相对狭窄，最佳方法仍然存在争议。虽然通常首选经胸入路，但我们采用了 2012 年描述的新技术：经硬膜后入路。我们的目的是评估其对巨大胸椎间盘突出患者的益处。我们回顾性回顾了 2012 年 7 月至 2020 年 3 月在我们神经外科接受治疗的所有患者。提取和分析了人口统计学、术前和术后临床状况、手术技术和并发症。2012 年至 2020 年期间，共有 12 名患者接受了巨大钙化胸椎间盘的后部经硬膜切除术。所有患者都接受了后路减压（椎板切除术、半椎板切除术或椎板成形术）。手术的中位持续时间为 152 分钟。4 名患者出现一过性术后神经功能恶化，直至出院时完全康复。没有患者接受手术翻修。通过后入路经硬膜切除巨大钙化胸椎间盘提供了良好的减压和充分的脊髓可视化和令人满意的术后结果。
