Early postoperative complications of thoracolumbar fractures in patients with multiple trauma according to the surgical timing / Complicaciones postoperatoriass de fracturas toracolumbares en pacientes con traumatismo múltiple según el momento de la cirugía

Introduction and objetctives: Our objective was to compare the rate of complications in thoracolumbar fractures that occurred during the early postoperative period in patients with multiple high-energy trauma according to the time of surgery. As a secondary objective, to estimate which variables were associated with surgery before 72h. Material and methods: Retrospective analysis of a series of patients with thoracolumbar fractures and multiple associated injuries in other anatomical regions due to high energy trauma. Surgically treated in an occupational trauma referral center, by the same surgical team and during the period between January 2013 and December 2019. Results: We analyzed a sample of 40 patients (39 men and 1 woman). The rate of complications was independent of surgical delay (before and after 72h) (p=0.827). There were statistically significant differences between early and later surgery groups in the variables age, systolic blood pressure, initial SOFA score and presence of neurological damage (p=0.014; p=0.029; p=0.032; p=0.012). The overall surgical delay was correlated with the SOFA score (p=0.007). Conclusion: The rate of early postoperative complications did not show significant differences between the early and late surgery groups. We observed that the patients who had been operated before 72h from trauma were younger, had more association with neurological syntoms, presented higher blood pressure values and less physiological damage. Surgical delay was positively correlated with SOFA score on arrival.(AU)

Introducción y objetivos: Nuestro objetivo es comparar la tasa de complicaciones acontecidas durante el postoperatorio temprano de fracturas toracolumbares en pacientes con traumatismos múltiples de alta energía según el momento de la cirugía. Como objetivo secundario, estimar qué variables se asociaron el desarrollo de la cirugía antes de las 72h. Materiales y métodos: Análisis retrospectivo de una serie de pacientes con fracturas toracolumbares y múltiples lesiones asociadas en otras regiones anatómicas por traumatismo de alta energía. Tratados quirúrgicamente en un centro de derivación de trauma laboral, por el mismo equipo quirúrgico y durante el período comprendido entre enero de 2013 y diciembre de 2019. Resultados: Se incluyeron 40 pacientes (39 hombres y una mujer). La tasa de complicaciones tempranas fue independiente del momento de la cirugía (antes o después de las 72h) (p=0,827). Se presentaron diferencias estadísticamente significativas entre ambos grupos en las variables edad, presión arterial sistólica, puntuación SOFA inicial y presencia de daño neurológico (p=0,014; p=0,029; p=0,032; p=0,012). La demora quirúrgica global se correlacionó con el puntuación SOFA al ingreso (p=0,007). Conclusión: La tasa de complicaciones en el postoperatorio temprano de fracturas toracolumbares no mostró diferencias significativas entre los grupos de cirugía temprana y tardía. Los pacientes operados antes de las 72h del trauma fueron más jóvenes, presentaron valores más elevados de presión arterial, menor daño fisiológico y asociaron síntomas neurológicos con mayor frecuencia. La demora quirúrgica se correlacionó positivamente con la puntuación SOFA al ingreso.(AU)

Cirugía mínimamente invasiva en el tratamiento de fracturas tóracolumbares / Minimally invasive surgery in the treatment of thoracolumbar fractures

Objetivo: Analizar y describir una serie de fracturas tóraco-lumbares traumáticas tratadas con cirugía mínimamente invasiva. Material y métodos: Analizamos una serie de 26 pacientes con fracturas traumáticas tóraco-lumbosacras entre 2010-2017. Las imágenes pre-operatorias fueron clasificadas usando la clasificación AO. Analizamos en forma pre y post operatoria: escala visual analógica, volumen de pérdida sanguínea, duración de la hospitalización, complicaciones, cirugías asociadas en otros órganos, extracción de implantes en el largo plazo, estado neurológico pre y post quirúrgico y mortalidad.Los pacientes con historias clínicas completas, TAC pre-operatoria y un seguimiento mínimo de 12 meses fueron incluidos (18 hombres y 8 mujeres). La edad promedio fue de 28.7 años (21-84 años); seguimiento promedio de 28 meses (13-86 meses). Dieciocho pacientes fueron manejados con instrumentaciones percutáneas, 8 recibieron vertebroplastias, y en 5 casos se realizó además algún gesto de artrodesis. Resultados: La EVA mejoró 7 puntos promedio respecto al pre-operatorio; el promedio de sangrado fue de 40 mL, no observamos ningún caso de empeoramiento neurológico. La duración promedio de la hospitalización fue de 3.9 días. Cuatro enfermos necesitaron alguna cirugía en otro órgano producto de sus politraumatismos.Los tornillos percutáneos fueron removidos en 9 casos luego de la consolidación. Como complicaciones tuvimos: 1 hematoma retroperitoneal autolimitado, una fractura pedicular y una cánula de cementación rota adentro de un pedículo. Conclusión: La cirugía mínimamente invasiva en trauma espinal es una alternativa válida que permite estabilización, movilización precoz y logra buenos resultados en términos de control del dolor con baja tasa de complicaciones

Objective: To analyze and describe a series of trauma-related thoraco-lumbo-sacral vertebral fractures managed with minimally invasive surgery. Methods: We retrospectively review the charts and images of 26 patients with thoracolumbar spine fractures between 2010-2017. Pre-op images were assessed and fractures were classified according to the thoraco-lumbar trauma AO Spine classification. We analyzed pre and post-surgical visual analog scale (VAS), blood loss during surgery, hospital length of stay, complications, associated surgical procedures, long term post-op implant removal, pre and post neurological status and mortality.Patients with a complete case record, pre-op CT scans and minimum 12-month follow up were included (18 males and 8 females). Mean age was 28.7 years (21-84 years); mean post-op follow up was 28 month (13-86 months). Eighteen patients were managed with percutaneous instrumentation, 8 patients also received percutaneous vertebroplasty, and 5 patients underwent also some arthrodesis procedure. Results: VAS improved 7 points as compared to the pre-op score; mean blood loss was 40 mL, we did not observed any neurological deficit worsening. Mean hospital length of stay was 3.9 days. Four patients needed surgical procedures involving other organs due to politrauma. Percutaneous screws were removed in 9 cases after fracture consolidation. Complications were: one case of self-limiting retroperitoneal hematoma, one case of pedicle screw fracture and one cement broken cannula into the pedicle. Conclusion: Minimally invasive surgery in spine trauma is a valid option allowing stabilization, early mobilization, and leading to good outcomes in terms of pain control and a lower complication rate

[Rationale and complications of the anterior-lateral extrapleural retroperitoneal approach for unstable thoracolumbar fractures: Experience in 86 consecutive patients]. / Fundamentos y complicaciones del abordaje anterolateral extrapleural-retroperitoneal en fracturas inestables toracolumbares: experiencia en 86 pacientes consecutivos.

OBJECTIVES: To describe the rationale, pros and cons, and complications of the anterior-lateral extrapleural retroperitoneal approach for unstable (TLICS>4) thoracolumbar fractures. PATIENTS AND METHODS: Clinical and radiological data and outcomes from a cohort treated surgically via said approach were retrospectively reviewed. All patients were operated on exclusively by 5 neurosurgeons trained in spine surgery. RESULTS: Between June 1999 and December 2015, 86 patients underwent surgery (median age 42years, most common level: L1). Approximately 32.5% presented with a preoperative neurological defect. After surgery (mean duration: 275minutes), 75.6% presented with no neurological sequelae and only one-third required blood transfusion. Median postoperative stay was 7days. Correction of kyphosis was considered adequate and suboptimal but acceptable in 91% and 9% of the patients, respectively. Complications occurred in 36 patients, the majority being transient. We observed failure of the construct in 2 cases (collapse of an expandable cage and extrusion of a locking screw). No infections, vascular or visceral lesions, permanent neurological worsening or mortality occurred during hospitalisation. One patient ultimately needed additional posterior fixation due to persistence of pain. Median follow-up was 252days (27.9% was lost to follow-up). CONCLUSIONS: The extrapleural extraperitoneal approach provides solid anterior reconstruction, allows wide decompression of the spinal canal, and permits adequate and long-lasting correction of kyphosis. The rates of infection, construct failure, need for reoperation and vascular or visceral lesions are minimal.

Prognostic value of an immediate lateral standing X-ray with a TLSO in patients with a thoracolumbar burst fracture.

UNLABELLED: The final collapse of a "stable" thoracolumbar burst fracture is difficult to predict. This collapse was prospectively studied radiologically in patients with T12 or L1 burst fractures who, after evaluating the admission x-rays and the CT scan with the patients themselves, opted for a rigid thoracolumbar brace with support in the sternal manubrium (TLSO). On the other hand, patients with rigid braces sometimes have low back pain on follow-up (due to overload of the L5-S1 joints). HYPOTHESIS: the standing lateral x-ray with only a TLSO for support (intrinsic mechanical stability) provides information on the final collapse and could also provide information on the low back pain. The study included 50 patients (20 males and 30 females, age: 63+14 years) admitted during 2011 and 2012, with 2 losses to follow-up. VARIABLES: Farcy index and local kyphosis (Cobb at 3 vertebrae). X-Rays: admission, with TLSO (immediate: Rx0), and at 3 and 6 months. They were compared with the final clinical and radiological results. It was decided to surgically intervene in 4 patients after Rx0. There were no painful sequelae at the fracture level, and 16/44 (31%) had low back pain. Using linear regression mathematical models, the increase in the Farcy index (Rx0-Rx admission) was associated with the appearance of low back pain and with local kyphosis (Rx0-Rx admission), and with the final kyphosis. It is advisable to perform a lateral standing X-ray after TLSO for information on the final collapse of the fracture and the appearance of accompanying low back pain.
