Posterior realignment of basilar invagination with facet joint distraction technique.

Purpose: We describe our experience with management of basilar invagination (BI) with the atlantoaxial dislocation (C1/C2) joint reduction technique, including posterior atlantoaxial internal fixation.

Materials And Methods: From 2008 to 2018, eleven patients with atlantoaxial dislocation (AAD) and BI underwent surgical reduction using C1/C2 the joint reduction technique with a fibular graft/peek cage placement followed by C1 lateral mass/C2 pedicle screw fixation. In two cases that we originally planned to perform C1/C2 joint reduction, occiput-C2 pedicle screw fixation was performed instead due to intraoperative challenges.

Lung Adenocarcinoma Metastasis Mimicking Peripheral Nerve Sheath Tumor: Case Report and Review of Literature.

Root metastases of solid organ carcinomas are rare entities. Because of their rare occurrence, they can be confused with nerve sheath tumors, such as schwannomas or neurofibromas, when detected by magnetic resonance imaging. In this paper, we reported a case of a 72-year-old woman with S1 root metastasis originating from lung adenocarcinoma.

Giant cell tumor of the eleventh thoracic vertebra in a pediatric patient: an interesting case report and comprehensive literature review.

The impact of antibiotic-impregnated catheters on ventriculoperitoneal shunt infection.

Background/aim: Ventriculoperitoneal shunt infections remain an important problem and result mainlyfrom perioperative colonization of shunt components by skin flora. Antibiotic-impregnated shunts have been designed to prevent such colonization. T'his study evaluates the incidence of shunt infection after the insertion of antibiotic-impregnated shunts in a population of children with hydrocephalus.

Two-stage multilevel cervical spondylectomy for aneurysmal bone cyst.

Aneurysmal bone cyst is a benign tumor-like bony lesion with a propensity to develop in the pediatric population. It generally involves one vertebral level when localized to the spine. The degree of resection correlates highly with fewer recurrences.

Quantitative evaluation of the anatomical parameters for subaxial cervical spondylectomy: an anatomical study.

Object: The object of this investigation was to conduct a morphometric study in cadavers to determine anatomical structures, their relationships, and their morphometry for subaxial cervical spondylectomy.

Material And Methods: 80 patients suffering from low back pain were included in the study.

Operative illustrations of the Osborne's ligament.

The cubital tunnel syndrome is widely considered as the second most frequent compression neuropathy in the upper extremities although the existence of a compressive cause has not been determined conclusively. As far as we know, operational photography of compression of the ulnar nerve at the elbow is almost never found in the literature. In this paper, operational and pathological photographs of the Osborne's ligament as a cause of ulnar entrapment neuropathy at the elbow are presented.

Safe zone for C1 lateral mass screws: anatomic and radiological study.

Objective: To evaluate the possible complications of overpenetrated C1 lateral mass screws and to identify and define a "safe zone" area anterior to the C1 vertebra.

Methods: The study was performed on 10 cadavers and 50 random patients who had undergone computed tomographic scanning with contrast medium of the neck for other purposes. Atlas lateral mass screw trajectories were plotted, and the safe zone for screw placement anterior to the atlas vertebra was determined for each trajectory.

Freehand C1 lateral mass screw fixation technique: our experience.

Background: Although C1 lateral mass fixation technique is frequently performed in upper cervical instabilities, it requires the guidance of fluoroscopic imaging. The fluoroscopy guidance is time-consuming and has the risks of accumulative radiation. Biplane fluoroscopy is also difficult in upper cervical pathologic conditions because of the use of cranial fixations.
