[Two treatment approaches for lumbar disc herniation and sequester migration to the second and third McCulloch's windows: transpedicular and translaminar sequestrectomy (ridit analysis)].

Herniated intervertebral discs with severe sequester migration should be divided in accordance with localization of the main sequestration. Transpedicular endoscopic approach is advisable for sequester in the third and rarely the second McCulloch's windows. Translaminar microsurgical approach is preferred for sequestration in the second and rarely the third McCulloch's windows. Clinical outcomes after translaminar microsurgical sequestrectomy and transpedicular endoscopic surgeries are similar. However, postoperative back and leg pain regression, neurological recovery and improvement of quality of life according to the Oswestry scoring system are more common after transpedicular surgery.
