[ Symptomatic Triple-Region Spinal Stenosis (TRSS): case report and narrative Literature Review].

Introduction: Simultaneous spinal stenosis in three regions of the spine is an unusual condition that demands proper clinical evaluation and imaging. Currently, there are no established guidelines for its diagnostic and therapeutic approach.

Objective: The objective of this study is to describe, based on a case report, the clinical presentation, treatment, and patient progression concerning triple stenosis, contrasting it with available evidence through a narrative review of the literature.

Three-level thoracic disc herniation: transthoracic decompression without fixation.

Thoracic disc herniation is a rare pathology compared to the rest of the herniated discs. Due to their difficult access to the area of compromise and proximity to the spinal cord they represent a real challenge for the spine surgeon. The objective is to report an atypical case with three symptomatic dorsal disc herniations which required surgical treatment.

Association between Modic changes and intervertebral vacuum phenomenon severity in patients undergoing percutaneous cement discoplasty.

Background: Modic changes and intervertebral vacuum phenomenon (IVP) are considered spinal degenerative changes. The correlation between Modic and IVP has not been analyzed in the literature.

Purpose: To analyze the correlation between IVP severity, Modic changes, and subchondral sclerosis across the lumbar spine in patients with lumbar degeneration.

Accuracy of intraoperative neuromonitoring during percutaneous cement discoplasty.

Introduction: Percutaneous cement discoplasty is a minimally invasive procedure to treat low back pain due to advanced degenerative disc disease in elderly patients. Complications of this procedure has been described such as infection, vertebral fracture, cement leakage and nerve injury. Intraoperative neuromonitoring is used to detect the latter.

Percutaneous Cement Discoplasty for Degenerative Low Back Pain with Vacuum Phenomenon: A Multicentric Study with a Minimum of 2 Years of Follow-Up.

Background: To report clinical results after percutaneous cement discoplasty (PCD) in a multicentric case series with a minimum of 2 years of follow-up.

Methods: Between December 2014 and January 2019, 180 patients with low back pain and advanced degeneration were treated with percutaneous discoplasty in 2 centers. The inclusion criteria were as follows: patients 65 years or older, with mechanical low back pain with or without spinal stenosis, who did not respond to conservative management.

Symptomatic Atlas Hypoplasia in a Latin-American Patient: Case Report and Literature Review.

Background: Atlas hypoplasia is an infrequent cause of upper cervical stenosis. Only 24 cases in nonsyndromic adult population have been published. We are not aware of previous reports describing isolated fully formed atlas hypoplasia in a Latin-American patient.

[La Frailty as a predictor index in spine surgery].

Introduction: Frailty is a term used to quantify the physiological age of patients. Higher levels of frailty correlate with higher complications and mortality rates after different surgical procedures. The objective of this work is to evaluate the relationship between frailty and the complications and mortality rates after elective spinal surgeries within 90 days.

Chylothorax, a rare complication after anterior lumbar interbody fusion. Case report.

Introduction: Chylous leakage into the retroperitoneum is a rare complication after spinal surgery using an anterior retroperitoneal approach. Chylothorax is the presence of lymphatic fluid in the pleural cavity and it is even less frequent during these surgeries. The aim of this work is to report the first case of isolated left chylothorax after a retroperitoneal Left Oblique Lumbar Interbody Fusion in supine position in an adult female patient.

Development of a New Therapy-Oriented Classification of Intervertebral Vacuum Phenomenon With Evaluation of Intra- and Interobserver Reliabilities.

Study Design: Diagnostic study, level of evidence III.

Objectives: Low back pain is a common cause of disability among elderly patients. Percutaneous discoplasty has been developed as a tool to treat degenerative disease when conservative management is not successful.

Percutaneous Cement Discoplasty for the Treatment of Advanced Degenerative Disc Conditions: A Case Series Analysis.

Study Design: Retrospective analysis. Level of evidence III.

Objectives: To describe the results after a minimum 1-year follow-up in patients treated with percutaneous discoplasty (PD), a minimally invasive technique to treat low back pain in elderly patients with advanced degenerative disc disease.

Short-term complication rate following orthopedic surgery in a tertiary care center in Argentina.

Introduction: Registration of adverse events following orthopedic surgery has a critical role in patient safety and has received increasing attention. The purpose of this study was to determine the prevalence and severity of postoperative complications in the department of orthopedic unit in a tertiary hospital.

Methods: A retrospective review from the postoperative complication registry of a cohort of consecutive patients operated in the department of orthopedic surgery from May 2015 to June 2016 was performed.

Percutaneous cement discoplasty for the treatment of advanced degenerative disk disease in elderly patients.

Purpose: The authors describe a percutaneous technique to treat advanced degenerative disk disease in elderly patients.

Method: A step-by-step technical description based on our experience in selected cases.

Result: Postoperative imaging results are presented as well as indications and recommendations.

Monosegmental combined anterior posterior instrumentation for the treatment of a severe lumbar tuberculous spondylodiscitis: case report and literature review.

Spinal tuberculosis (Pott disease) can produce severe deformities when it is not properly treated. Long instrumentations through single or combined double approaches are usually required to prevent and correct the deformity. The authors present a case of severe deformity secondary to tuberculous spondylodiscitis in the lumbar spine treated with a monosegmental instrumentation through a double approach in a patient with idiopathic scoliosis.

Usefulness of Tokuhashi Score in Survival Prediction of Patients Operated for Vertebral Metastatic Disease.

Study Design: Retrospective study.

Objective: Spinal metastasis can produce pain, deformity, neurological compromise and can decrease life expectancy. Surgical management is usually indicated for pain control, neurological decompression, and to avoid deformity progression.

Use of CT-guided periradicular injection for the treatment of foraminal and extraforaminal disc herniations.

Study Design:  Retrospective case series. Evidence level IV.

Objectives:  To evaluate surgical candidates with foraminal or extraforaminal lumbar disc herniation treated with CT-guided periradicular injection (CTGPI) as a valid treatment option for avoiding surgery.

The influence of anatomy (normal versus scoliosis) on the free-hand placement of pedicle screws: Is misplacement more frequent in patients with anatomical deformity?

Study Design:  Retrospective prognostic study.

Objective:  To evaluate whether patients with anatomical deformity due to scoliosis have a higher frequency of inaccurate pedicle screw insertion and related complications using the free-hand technique compared with those whose normal anatomy had been impacted by trauma.

Methods:  Consecutively treated trauma patients with otherwise normal anatomy (48 patients instrumented with 291 screws, group A) and scoliosis patients (24 patients instrumented with 287 screws, group B) were evaluated.
