Abstract
The aims of spinal deformity surgery are to achieve balance, relieve pain and prevent recurrence or worsening of the deformity.The main types of osteotomies are the Smith-Petersen osteotomy (SPO), pedicle subtraction osteotomy (PSO), bone-disc-bone osteotomy (BDBO) and vertebral column resection (VCR), in order of increasing complexity.SPO is a posterior column osteotomy in which the posterior ligaments and the facet joints are removed and correction is performed through the disc space. A mobile anterior disc is essential. SPO is best in patients with +6-8 cm C7 plumbline. The amount of correction is 9.3° to 10.7°/level (1°/mm bone).PSO is a technique where the posterior elements and pedicles are removed. Then a triangular wedge through the pedicles is removed and the posterior spine is shortened using the anterior cortex as a hinge. The ideal candidates are patients with a severe sagittal imbalance. A single level osteotomy can produce 30° 40° of correction. A single level osteotomy may restore global sagittal balance by an average of 9 cm with an upper limit of 19 cm.BDBO is an osteotomy done above and below a disc level. A BDBO provides correction rates in the range of 35° to 60°. The main indications are deformities with the disc space as the apex and severe sagittal plane deformities.VCR is indicated for rigid multi-planar deformities, sharp angulated deformities, hemivertebra resections, resectable spinal tumours, post-traumatic deformities and spondyloptosis. The main indication for a VCR is fixed coronal plane deformity.The type of osteotomy must be chosen mainly according to the aetiology, type and apex of the deformity. One may start with SPOs and may gradually advance to complex osteotomies.

Resumen
Los principales tipos de osteotomías son la osteotomía de Smith-Petersen (SPO), la osteotomía de sustracción de pedículos (PSO), la osteotomía ósea-disco-ósea (BDBO) y la resección de columna vertebral (VCR), en orden de complejidad creciente.SPO es una osteotomía de columna posterior en la que los ligamentos posteriores y las articulaciones de las facetas se eliminan y la corrección se realiza a través del espacio discal. Un disco anterior móvil es esencial. SPO es mejor en pacientes con plumbline C7 de + 6-8 cm. La cantidad de corrección es de 9,3 ° a 10,7 ° / nivel (1 ° / mm de hueso) .PSO es una técnica en la que se eliminan los elementos posteriores y los pedículos. Luego se retira una cuña triangular a través de los pedículos y la espina posterior se acorta utilizando la corteza anterior como una bisagra. Los candidatos ideales son pacientes con un desequilibrio sagital severo. Una osteotomía de un solo nivel puede producir 30 ° 40 ° de corrección. Una osteotomía de un solo nivel puede restablecer el equilibrio sagital global en un promedio de 9 cm con un límite superior de 19 cm.BDBO es una osteotomía realizada por encima y por debajo de un nivel de disco. Un BDBO proporciona tasas de corrección en el intervalo de 35 ° a 60 °. Las principales indicaciones son deformidades con el espacio discal como el ápice y las deformidades severas del plano sagital. VCR está indicado para deformidades rígidas multiplanares, deformidades anguladas agudas, resecciones de hemivertebra, tumores espinales resecables, deformidades postraumáticas y espondiloptosis. La principal indicación de un VCR es la deformidad del plano coronal fijo. El tipo de osteotomía debe elegirse principalmente de acuerdo con la etiología, el tipo y el ápex de la deformidad. Uno puede comenzar con los SPOs y puede avanzar gradualmente a osteotomías complejas

Minimally invasive spine surgery (MISS), spurred by technological advancement and the desire to optimize patient outcomes, has reshaped the delivery of surgical spine care over the past several decades. The advantage of MISS lies in its ability to adequately treat the pathology while minimizing tissue injury. MISS has been shown to decrease blood loss and length of stay compared to open approaches for select indications.
La cirugía de columna mínimamente invasiva (MISS), impulsada por el avance tecnológico y el deseo de optimizar los resultados de los pacientes, ha reformado la prestación de atención quirúrgica de la columna durante las últimas décadas. La ventaja de la MISS radica en su capacidad para tratar adecuadamente la patología y minimizar la lesión tisular. MISS se ha demostrado que disminuye la pérdida de sangre y la duración de la estancia en comparación con los abordajes abiertos para indicaciones seleccionadas.

The concept of minimally invasive surgery has gained increasing popularity in the last several decades in large part due to the great leaps forward witnessed by many subspecialties. The triumphs of minimally invasive innovation have included the transition from the morbidity of median sternotomy, or thoracotomy for open cardiothoracic procedures, to percutaneous catheter-based cardiac vessel and valve procedures, and the transition from open arthrotomy during sport procedures in the shoulder or knee to a specialty dominated almost entirely by the arthroscope….
