Odontoid remodeling with occipital condyle stabilization in patients with metastatic C2 involvement.

The occipitocervical junction (OCJ) is a complex anatomical region crucial for protecting the lower brain stem, upper spinal cord, and lower cranial nerves. Instability in this area can lead to severe outcomes such as chronic pain, neurological deficits, or death. Various surgical techniques have been developed for OCJ stabilization, particularly using occipital condyle screws, which have shown promise in providing stability and preserving neck rotation.

Additionally, we investigate the impact of surgical experience on outcomes by comparing early and late cases operated on with neuronavigation.

Can Dynamic Spinal Stabilization Be an Alternative to Fusion Surgery in Adult Spinal Deformity Cases?

Background: Rigid stabilization and fusion surgery are widely used for the correction of spinal sagittal and coronal imbalance (SCI). However, instrument failure, pseudoarthrosis, and adjacent segment disease are frequent complications of rigid stabilization and fusion surgery in elderly patients. In this study, we present the results of dynamic stabilization and 2-stage dynamic stabilization surgery for the treatment of spinal SCI.

Does long segment subarachnoido-subarachnoid shunt prevent posttraumatic and postinfectious spinal arachnoid cyst recurrence?: technical note and case series.

Syringomyelia associated with extensive spinal adhesive arachnoiditis (SAA) can be defined as a rare but progressive disease with potentially devastating clinical consequences. Diagnosis can be challenging due to the absence of specific clinical findings, confusion with other pathologies, and late imaging modalities. The treatment strategy for syringomyelia associated with extensive SAA should include direct drainage of the syringomyelia, and dissection of the adhesive arachnoid with expansive duraplasty.

Use of Dynamic Spinal Instruments (Dynesys) in Adult Spinal Deformities According to Silva-Lenke and Berjano-Lamartina Classifications.

Background: Adult spinal deformities (ASD) present complex challenges in spine surgery. The diverse nature of these deformities requires a comprehensive understanding of their classification and treatment options. Traditional approaches, such as fusion and rigid stabilization are associated with complications, including screw loosening, breakage, proximal junctional kyphosis (PJK), and pseudoarthrosis.

The clinical and radiological course of these values was monitored, and their interaction with all spinal radiological parameters was revealed.

Should Iliac Wing Screws Be Included in Long Segment Dynamic Stabilization?

Background In this article, clinical satisfaction and radiological results are discussed in a series of patients where the iliac wings participate in dynamic stabilization. Dynamic stabilization is an effective alternative surgical treatment method, especially in clinical pictures that go with pain due to minor instabilities. Practically the unique surgical instrument used in multilevel instabilities is the Dynesys system.

Comparison of Two Minimally Invasive Techniques with Endoscopy and Microscopy for Extraforaminal Disc Herniations.

Objective: Extraforaminal disc herniations are extraordinary herniations because they are located outside the foraminal bony borders and compress the root exiting at the corresponding level, whereas in median or paramedian herniations, the root 1 level below is compressed. Percutaneous endoscopic discectomy (PED) and microscopic extraforaminal discectomy (MEFD) are 2 popular contemporary techniques that have been performed extensively for these herniations since the 1970s.

Methods: In this study, we retrospectively analyzed 118 patients who underwent either PED (66 patients) or MEFD (52 patients).

A new concept of motion preservation surgery of the cervical spine: PEEK rods for the posterior cervical region.

Background: Laminectomy may cause kyphotic postoperative deformity in the cervical region leading to segmental instability over time. Laminoplasty may be an alternative procedure to laminectomy, as it protects the spine against post-laminectomy kyphosis; however, similar to laminectomy, laminoplasty may cause sagittal plane deformities by destructing or weakening the dorsal tension band.

Objective: Using finite element analysis (FE), we attempted to determine whether a posterior motion preservation system (PEEK posterior rod system concept) could overcome the postoperative complications of laminectomy and laminoplasty and eliminate the side effects of rigid posterior stabilization in the cervical region.
