Necessity of fusion following decompression surgery in patients with single-level lumbar stenosis: study protocol for an open-label multicentre non-inferiority randomized controlled clinical trial.

Background: The necessity of spinal segment fusion after decompression is one of the most controversial and unresolved issues in single-level lumbar spinal stenosis surgery. To date, only one trial carried out 15 years ago focused on this problem. The key purpose of the current trial is to compare the long-term clinical results of the two surgical methods (decompression vs.

Endoscopic Endonasal Resection of the Odontoid Process in a Patient with Chronic Injury of the C1 Transverse Ligament.

Atlas dislocation after transverse ligament injury is one of the most rare types of trauma to the upper cervical level. If magnetic resonance imaging of the craniovertebral junction reveals the Kassam line passing through the cervix of the odontoid process, a transnasal approach can be used for surgical treatment. Here, we present a case in which an endoscopic endonasal approach was used to treat chronic traumatic transligamentous atlas dislocation.

Minimally Invasive Surgical Treatment for Vertebral Artery Compression in a Patient with One-Sided Ponticulus Posticus and Ponticulus Lateralis.

Background: Kimmerle anomaly is characterized by ossification of the posterior atlanto-occipital membrane with formation of a complete or incomplete bony ridge in the area of the groove for the vertebral artery (VA) (ponticulus posticus [PP]). In some cases, the bony ridge may also be formed at the level of the VA emerging from the transverse process of the С1 vertebra (ponticulus lateralis [PL]). Simultaneous 1-sided formation of PL and PP is very rare.

Minimally invasive surgical treatment for Kimmerle anomaly.

Introduction: Kimmerle anomaly is the bony ridge between the lateral mass of atlas and its posterior arch or transverse process. This bony tunnel may include the V3 segment of the vertebral artery, vertebral vein, posterior branch of the C1 spinal nerve, and the sympathetic nerves, which results in the clinical symptoms of this disease. Reports on the surgical treatment of Kimmerle anomaly are rare.

Anterior transarticular C1-C2 fixation with contralateral screw insertion: a report of two cases and technical note.

Purpose: Anterior transarticular fixation of the C1-C2 vertebrae is a well-known technique that involves screw insertion through the body of the C2 vertebra into the lateral masses of the atlas through an anterior transcervical approach. Meanwhile, contralateral screw insertion has been previously described only in anatomical studies.

Methods: We describe two case reports of the clinical application of this new technique.
