The full-endoscopic uniportal technique for decompression of the anterior craniocervical junction using the retropharyngeal approach: an anatomical feasibility study in human cadavers and review of the literature.

Objective: Acute or progressive myelopathy may necessitate direct anterior decompression of the craniocervical junction and odontoidectomy. Different techniques with individual advantages and disadvantages can be used. In addition to the gold standard-the transoral approach-there is also increasing experience with the endoscopic transnasal technique.

Full-endoscopic uniportal retropharyngeal odontoidectomy for anterior craniocervical infection.

Background: Infections of the anterior craniocervical junction may require surgery. There are various techniques with individual advantages and disadvantages. This study evaluates the full-endoscopic uniportal technique via the anterior retropharyngeal approach for odontoidectomy, decompression, and debridement.

Operation of Soft or Calcified Thoracic Disc Herniations in the Full-Endoscopic Uniportal Extraforaminal Technique.

Background: Surgery for thoracic disc herniation and stenosis is comparatively rare and often demanding. The goal is to achieve sufficient decompression without manipulating the spinal cord and to minimize surgical trauma and its consequences. Individual planning and various surgical techniques and approaches are required.

Surgical treatment of cervical subaxial intraspinal extradural cysts using a full-endoscopic uniportal posterior approach.

Purpose: Symptomatic intraspinal extradural cysts of the cervical subaxial spine are rare, but usually require surgery. Conventional posterior decompression is the gold standard. However, there is increasing experience with endoscopic surgical techniques.

Decompression of the anterior thoracic spinal canal using a novel full-endoscopic uniportal transthoracic retropleural technique-an anatomical feasibility study in human cadavers.

Surgery for thoracic disc herniation and spinal stenosis is comparatively rare and often demanding. The goal is to achieve sufficient decompression without manipulating the spinal cord. Individual planning and various surgical techniques and approaches are required.

Full-endoscopic Uniportal Odontoidectomy and Decompression of the Anterior Cervicomedullary Junction Using the Retropharyngeal Approach.

Study Design: A study of a series of consecutive full-endoscopic uniportal decompressions of the anterior craniocervical junction with retropharyngeal approach.

Objective: The aim of this study was to evaluate the direct anterior decompression of the craniocervical junction in patients with bulbomedullary compression using a full-endoscopic uniportal technique via an anterolateral retropharyngeal approach.

Summary Of Background Data: Acute or progressive myelopathy may necessitate direct anterior decompression of the craniocervical junction and odontoidectomy.

Decompression for cervical disc herniation using the full-endoscopic anterior technique.

Objective: Resection of a cervical disc herniation using a full-endoscopic technique with an anterior approach.

Indication: Fresh disc herniation with monoradicular symptoms in the upper extremity.

Contraindications: Pure neck pain, cervical myelopathy, older and calcified disc herniations, higher grade of instability and deformity.

Full-endoscopic posterior foraminotomy surgery for cervical disc herniations.

Objective: Surgery for cervical disc herniation with full-endoscopic posterior access.

Indications: Cervical disc herniation and neuroforaminal pathology with radicular symptoms.

Contraindications: Neck pain alone, cervical myelopathy or pathologies with central nervous system symptoms, instabilities requiring correction/instabilities.

[Decompression for cervical disc herniation using the full-endoscopic anterior technique - German version].

Objective: Resection of a cervical disc herniation using a full-endoscopic technique with an anterior approach.

Indication: Fresh disc herniation with monoradicular symptoms in the upper extremity.

Contraindications: Pure neck pain, cervical myelopathy, older and calcified disc herniations, higher grade of instability and deformity.

A New Electromagnetic Navigation System for Pedicle Screws Placement: A Human Cadaver Study at the Lumbar Spine.

Introduction: Technical developments for improving the safety and accuracy of pedicle screw placement play an increasingly important role in spine surgery. In addition to the standard techniques of free-hand placement and fluoroscopic navigation, the rate of complications is reduced by 3D fluoroscopy, cone-beam CT, intraoperative CT/MRI, and various other navigation techniques. Another important aspect that should be emphasized is the reduction of intraoperative radiation exposure for personnel and patient.

Navigation of pedicle screws in the thoracic spine with a new electromagnetic navigation system: a human cadaver study.

Introduction: Posterior stabilization of the spine is a standard procedure in spinal surgery. In addition to the standard techniques, several new techniques have been developed. The objective of this cadaveric study was to examine the accuracy of a new electromagnetic navigation system for instrumentation of pedicle screws in the spine.

Bilateral spinal decompression of lumbar central stenosis with the full-endoscopic interlaminar versus microsurgical laminotomy technique: a prospective, randomized, controlled study.

Background: Extensive decompression with laminectomy, where appropriate, is often still described as the method of choice when operating on degenerative lumbar spinal stenosis. Nonetheless, tissue-sparing procedures are becoming more common. Endoscopic techniques have become the standard in many areas because of the surgical advantages they offer and the benefits for rehabilitation.

[Decompression of lumbar lateral spinal stenosis: full-endoscopic, interlaminar technique].

Objective: Decompression in lumbar recess stenosis in a full-endoscopic technique using an interlaminar approach.

Indications: Lumbar recess stenosis due to ligamentous, osseous, discogenic compression, and/or juxta-facet cysts.

Contraindications: Pure back pain, instability/deformity requiring correction, pure foraminal stenosis.

Anterior cervical discectomy and fusion: comparison of titanium and polyetheretherketone cages.

Background: Titanium (TTN) cages have a higher modulus of elasticity when compared with polyetheretherketone (PEEK) cages. This suggests that TTN-cages could show more frequent cage subsidence after anterior cervical discectomy and fusion (ACDF) and therefore might lead to a higher loss of correction. We compared the long term results of stand-alone PEEK- and TTN-cages in a comparable patient collective that was operated under identical operative settings.
