Extraforaminal Full-Endoscopic Approach for the Treatment of Lateral Compressive Diseases of the Lumbar Spine.

Background: The authors conducted a 2-year retrospective follow-up to investigate the efficiency of an extraforaminal full-endoscopic approach with foraminoplasty used to treat lateral compressive diseases of the lumbar spine in 247 patients.

Methods: The visual analogue scale (VAS), Oswestry disability index (ODI), and MacNab scale were used to analyze the results collected during the preoperative and postoperative periods.

Results: The most common diagnosis was disk herniation with lateral recess stenosis, and the most common surgical level among patients was between L4 and L5 on the left side.

STERNUM TOMOGRAPHIC EVALUATION IN PECTUS PATIENTS: ANALYSIS OF SAGITAL PARAMETERS.

Objective: To evaluate the sagittal tomographic reformatting of the sternum using unpublished radiographic parameters (indexes and angles), comparing them between the different types of pectus, and controls.

Methods: 44 patients with pectus deformities and controls underwent chest CT for analysis. The types of pectus were classified into: inferior (IPC), superior (SPC) and lateral (LPC), and broad (BPE) and localized (LPE).

Use of a Customized Three-dimensional Guide in Preparing the Pilot Pedicle Hole in Spinal Deformities.

 The present study aimed to develop and evaluate the use of customized guides in patients undergoing surgery to correct vertebral deformity with a pedicular fixation system.  Four patients with spinal deformity (three with idiopathic scoliosis and one with congenital kyphoscoliosis) underwent surgical treatment to correct the deformity with a pedicular fixation system. Prototypes of 3D cost guides were developed and evaluated using technical feasibility, accuracy, and radiation exposure.

Dural Injury Treatment with a Full-Endoscopic Transforaminal Approach: A Case Report and Description of Surgical Technique.

Introduction: The objective of this study was to describe a surgical technique that uses transforaminal full-endoscopic access, which is different from the existing protocol, and to demonstrate another method of dural tear repair during endoscopic spine surgery.

Background: Endoscopic spine surgery was initially described for lumbar disc pathologies. Technical advances and new materials have made it possible to treat cervical and thoracic spinal degenerative disorders.

ANALYSIS OF STERNAL CURVATURE PATTERNS IN PATIENTS WITH PECTUS AND CONTROL.

Objective: To analyze reformatted sagittal sternal tomography images and classify sternal body curvature types, and compare different types of populations with one another and with normal individuals.

Methods: In total, 50 controls and 167 pectus patients were selected for chest CT to analyze the median sagittal plane, of whom 89 had mean age, 12 ± 10 years) and 78 (mean age, 14 ± 10 years). Clinical types of were classified as inferior, superior, or lateral and localized or broad The following types of sternal patterns were defined: gradual vertical curve, gradual posterior curve, gradual anterior curve, proximal third curve, middle third curve, distal third curve, anterior rectilinear, vertical rectilinear, and posterior rectilinear.

Cervical Myelopathy Secondary to Gout: Case Report.

Gout is a crystalline arthropathy frequent in the population, but gouty spondyloarthropathy, also called axial gout, is uncommon. The current case report presents a rare case of cervical myelopathy secondary to axial gout. A 50-year-old female patient, without previous pathologies, presented with loss of strength, altered sensitivity, and pyramidal release for 2 years.

The Role of Pedicle Screw Surface on Insertion Torque and Pullout Strength.

 Compare by mechanical tests the pullout resistance and the insertion torque of rough and smooth pedicle screws.  Pedicle screws with rough surface and smooth surface, with diameters of 4.8; 5.

CHANGES IN THE LUMBAR VERTEBRAL SEGMENT RELATED TO THE CAGE POSITION IN TLIF TECHNIQUE.

Objective: To evaluate the morphological changes on the intervertebral foramen and segmental lordosis related to the transforaminal lumbar interbody fusion (TLIF) positioning.

Methods: PEEK cages were placed in the disc space (L1-S1) of a polyurethane anatomical model. Cages of different heights (8 mm, 10 mm, 12 mm and 14 mm) were positioned in the posterior, medial or anterior part of the vertebral body surface, and the intervertebral foramen and segmental lordosis heights were measured after their insertion.
