The influence of the rib cage on the severity of thoracic spine burst fractures

Coluna/Columna; 21 (1), 2022
ABSTRACT Objective: To analyze the anatomic influence of the ribs related to the severity of thoracic spine burst fractures. Methods: A retrospective review of 28 patients with thoracic spine burst fractures hospitalized by the Spine Group of the Hospital Ortopédico de Passo Fundo between January 2002...

Osteoporotic spine fractures treated with kyphoplasty or vertebroplasty: a meta-analysis

Coluna/Columna; 21 (2), 2022
ABSTRACT Kyphoplasty (KP) and vertebroplasty (VP) are both widely adopted treatments for patients with osteoporotic vertebral fractures (OVF), however, which of these techniques is more effective has not yet been established. We performed a systematic review of articles, followed by meta-analysis, in an ...

Hounsfield units use in spinal surgery planning: systematic review and meta-analysis

Coluna/Columna; 21 (3), 2022
ABSTRACT Bone mineral density is a crucial factor in the success or failure of osteosynthesis in spine surgery; it shows the onset of osteoporosis and related complications. Its evaluation is verified by dual-energy X-ray absorptiometry (DEXA) and Hounsfield Unit (HU) measurement by CT scan. Objective: D...

Finite element analysis of thoracic vertebral stability supported by the fourth spine

Coluna/Columna; 21 (4), 2022
ABSTRACT Objective: In traumatic injuries of the thoracic spine, three variables are analyzed to make decisions: morphology of the injury, posterior ligamentous complex and neurological status; currently the fourth column is not evaluated; our objective was to determine the biomechanical behavior of the...

Enfermedad ósea de Paget: reporte de caso
Paget's disease of bone: case report

La enfermedad ósea de Paget es una alteración metabólica generada por un disbalance entre la actividad osteoclástica y osteoblástica, llevando a un proceso de remodelación inadecuado que genera cambios en la estructura ósea. Aunque en muchos casos puede ser asintomática, se asocia a complicacione...

Percutaneous instrumentation without arthrodesis for thoracolumbar burst fractures (a3/a4, b): a retrospective study

Coluna/Columna; 20 (4), 2021
ABSTRACT Objective: There is still no consensus as to the treatment options for thoracolumbar burst fractures, although these fractures are widely described in the literature. The aim of this study was to evaluate the clinical and radiological outcomes of percutaneous instrumentation without arthrodesis...

Spinal deformity index and quality of life of patients with a densitometric diagnosis of osteoporosis

Coluna/Columna; 20 (4), 2021
ABSTRACT Objective: To evaluate the existence of a possible significant correlation between the quality of life of outpatients with osteoporosis and the Spinal Deformity Index (SDI), a radiographic method for semiquantitative assessment of the spine that enables the identification of prevalent and incid...

Estudio comparativo entre fijador externo versus placa volar de estabilidad angular en las fracturas de radio distal

Las fracturas del radio distal están entre las patologías más comunes en el área de la emergencia, actualmente los tratamientos más utilizados son la fijación con alambres de Kirschner y fijador externo (AKFE), o la osteosíntesis con placas volares de estabilidad angular (PVEA), realizamos un estu...

Comparación del tratamiento de las fracturas supracondíleas de húmero Gartland II y III con técnica de Dorgan versus técnica Cruzada. Hospital General del Sur “Dr. Pedro Iturbe”+

Se comparó la osteodesis por técnica lateral de Dorgan con la técnica Cruzada tradicional o de “Banderillero” en fracturas supracondíleas de húmero Gartland II y III. Se realizó un estudio descriptivo correlacional con diseño experimental. Se incluyeron 24 pacientes, los cuales se distribuyero...

Efeitos de três diferentes métodos de treinamento físico sobre os biomarcadores do estresse oxidativo e qualidade óssea de ratas no período da periestropausa

O sedentarismo associado à diminuição da concentração plasmática de estrogênio aumenta o estresse oxidativo e promove alterações na homeostase óssea, culminando na osteopenia, que pode evoluir para osteoporose, aumentar a fragilidade óssea e o risco de fraturas. Assim, o presente estudo teve c...
