[Classification of continuous multilevel vertebral fractures].

Currently there is still little information about multilevel vertebral fractures (MVF), in addition to the fact that there are no classifications that help us group them in a simpler way, and guide us on their prognosis. The objective of this work is to propose a new classification of continuous type MVF, based on the number of end plates injured of the vertebral bodies and their severity, where we form four groups. A review of continuous MVF cases that we found in our hospital over a 6-year period was carried out, managing to designate 100% of the fractures, by their characteristics, to the corresponding group.

[Radiation exposure of the spine surgeon].

Introduction: in general, spine surgeons seek to minimize soft tissue damage by using less invasive approaches, which causes them to use intraoperative images much more frequently than other surgical specialties; therefore, they are at increased risk of radiation exposure.

Objective: the aim of this work was to analyse the amount of radiation to which the spine surgeon is exposed in different scenarios.

Material And Methods: a prospective study with a descriptive, longitudinal non-randomized data source.

Giant Cell Tumor of the Thoracic Spine in a Young Female Patient in a México City Spine Center: A Case Report.

BACKGROUND Giant cell tumors of the bone (GCTB) are rare, locally aggressive benign neoplasms that primarily occur in the metaphyses of long bones. In less than 2% of cases, GCTBs arise in the spine, predominantly below the sacrum. We report the clinical manifestations, diagnostic approach, and successful surgical treatment of a patient with a GCTB of the thoracic spine.

Spinal canal invasion as a predictor of neurological deficit in traumatic vertebral burst fractures.

Background: This study correlated the extent of spinal canal compression from retropulsed traumatic burst cervical, thoracic, and lumbar spine fractures with the severity of neurological dysfunction.

Methods: One hundred and sixty-nine patients with cervical, thoracic, or lumbar sub-axial traumatic burst fractures were seen in an emergency department from 2019 to 2021; 79.3% were men, averaging 37 years of age.

[Traumatic spondyloptosis C7-T1 without neurologic deficit].

Traumatic spondyloptosis is a serious injury usually caused by high-energy trauma; It consists of the anterior or posterior dislocation of 100% or more of the underlying vertebral body, which can become a total injury of the spinal cord, producing a neurological deficit; this type of injury represents stage 4 and 5 of Allen-Ferguson. A 50-year-old man who suffers a car accident, he receive frontal impact when he was a driver, colliding with the retaining wall, referred from another hospital to emergency room, managed with C7 hemicorpectomy, c7-t1 discectomy, spondylodesis with anterior plate (C6-T1), and posterior approach + Fascetectomies of C7-T1, facet joint screws C6 and transpedicular fixation of T1. Subaxial cervical spondyloptosis is relatively rare clinical entity, a complete clinical examination is important in diagnosis, taking in considerations the injury mechanism.

[Morphometric analysis of cervical pedicles in a Mexican population].

Background: Knowledge of the morphometric anatomy of cervical pedicles is essential for the safe and accurate placement of pedicle screws during instrumentation of the cervical spine. Screw placement in the lumbar and thoracic vertebrae is considered as a safe practice, unlike the cervical vertebrae due to the risks involved. There are few reports on this technique.

[Fracture dislocation of the thoracolumbar spine in pregnant patient: diagnostic by image and treatment].

Background: Fracture dislocations of the thoracolumbar spine are, to a great extent, associated with neurologic deficit and instability, so a large percentage of them require surgical treatment. Being pregnant does not rule out the possibility of having this type of lesions. There are only a few bibliographic references concerning these cases and medical and treatment ignorance about them is frequent.

[Neurologic changes in patients with traumatic cord lesion based in the analysis of the sequential clinical history].

Objective: To determine changes in neurological status in patients with traumatic cord lesions before and after surgical treatment.

Material And Methods: We conducted a descriptive cohort study, and measured 61 points of neurologic evaluation (sensory, motor, reflexes) of the Sequential Clinical History.

Results: We studied 28 patients with complete cord lesion (ASIA A) and 16 with incomplete cord lesions (9 ASIA B, 4 ASIA C, and 3 ASIA D).

[Metabolic changes and nutritional status in the spinal cord injured patient ASIA A. Evaluation and monitoring with routine laboratories, a feasible option].

Introduction: Spinal Cord Injury ASIA A (tetraplegia) is a frequent pathology that may affect population regardless of age, sex or race, and that can induce metabolic abnormalities that may worsen the nutritional status of these patients. There are no existing specific protocols to treat these disorders in the specialized units in Mexico.

Material And Methods: We analyzed 16 patients at the Spine Clinic SS-DF, 18 years or older without any drug treatment or any previous disease, known or diagnosed when admitted to the hospital.
