Resumen

Durante las últimas dos décadas, el número de cirugías de columna realizadas anualmente ha aumentado de forma constante, y estos procedimientos se acompañan de un número cada vez mayor de estudios de imagenología postoperatoria para su interpretación. La TC es precisa para identificar la ubicación e integridad de los implantes, evaluar el éxito de los procedimientos de descompresión y artrodesis intervertebral, y detectar y caracterizar las complicaciones relacionadas. Aunque la TC de columna postoperatoria suele ser limitada debido a los artefactos causados por los implantes metálicos, la optimización de parámetros y las técnicas avanzadas de reducción de artefactos metálicos, incluyendo la reconstrucción iterativa y los métodos de extrapolación monoenergética, pueden utilizarse para reducir la gravedad de los artefactos metálicos y mejorar sustancialmente la calidad de la imagen. Los implantes y prótesis de columna comúnmente utilizados y recientemente disponibles incluyen tornillos y alambres, varillas estáticas y extensibles, injertos óseos y materiales biológicos, jaulas intersomáticas y prótesis de disco intervertebral. La evaluación por TC y el espectro de complicaciones que pueden presentarse tras la cirugía de columna y la artroplastia intervertebral incluyen las relacionadas con la posición e integridad de implantes y prótesis, la degeneración de segmentos adyacentes, colecciones, fístulas, pseudomeningoceles, fugas de líquido cefalorraquídeo e infecciones del sitio quirúrgico. El conocimiento de las numerosas técnicas y dispositivos de cirugía de columna ayuda a diferenciar los hallazgos postoperatorios esperados de las complicaciones. Se revisan los diversos tipos de instrumentación para cirugía de columna y los implantes espinales comúnmente utilizados. Los autores también describen e ilustran los hallazgos normales de columna postoperatoria, los signos de una cirugía exitosa y el amplio espectro de complicaciones postoperatorias que pueden ayudar a los radiólogos a generar informes que aborden los aspectos que el cirujano necesita conocer para un manejo óptimo del paciente.

abstract = "During the past 2 decades, the number of spinal surgeries performed annually has been steadily increasing, and these procedures are being accompanied by a growing number of postoperative imaging studies to interpret. CT is accurate for identifying the location and integrity of implants, assessing the success of decompression and intervertebral arthrodesis procedures, and detecting and characterizing related complications. Although postoperative spinal CT is often limited owing to artifacts caused by metallic implants, parameter optimization and advanced metal artifact reduction techniques, including iterative reconstruction and monoenergetic extrapolation methods, can be used to reduce metal artifact severity and improve image quality substantially. Commonly used and recently available spinal implants and prostheses include screws and wires, static and extendable rods, bone grafts and biologic materials, interbody cages, and intervertebral disk prostheses. CT assessment and the spectrum of complications that can occur after spinal surgery and intervertebral arthroplasty include those related to the position and integrity of implants and prostheses, adjacent segment degeneration, collections, fistulas, pseudomeningoceles, cerebrospinal fluid leaks, and surgical site infections. Knowledge of the numerous spinal surgery techniques and devices aids in differentiating expected postoperative findings from complications. The various types of spinal surgery instrumentation and commonly used spinal implants are reviewed. The authors also describe and illustrate normal postoperative spine findings, signs of successful surgery, and the broad spectrum of postoperative complications that can aid radiologists in generating reports that address issues that the surgeon needs to know for optimal patient management.",
