    Ley de Violencia Escolar en Chile desde la percepción y valoración de sostenedores municipales
    (2019) Bravo, José; Varela, Jorge J.; Pereira, Adrián; González, Rodrigo; Guerrero, Valeria
    Desde la creación de la Ley de Violencia (N°20.536) en Chile hemos visto importantes avances en diferentes reformas del sistema escolar chileno. No obstante, desconocemos la percepción y valoración que tiene esta legislación para los diferentes actores del sistema escolar de nuestro país. Para el presente estudio se aplicó una encuesta semi-estructurada a 96 sostenedores municipales a lo largo de Chile en la cual se abordaron tres dimensiones respecto de la (1) evaluación general de la ley, (2) implementación de la ley y (3) valoración general de esta. Como resultado se encontró que si bien la gran mayoría de los sostenedores reportan conocer la ley, que las principales estrategias de la misma se están implementando en los establecimientos a su cargo y que consideran que la normativa es un aporte a la gestión de la convivencia y a la prevención de la violencia escolar, finalmente la calificación final evidencia una valoración baja de éste cuerpo normativo por parte de los sostenedores.

    Spondylolysis Repair Using a Minimally Invasive Modified Buck Technique with Neuronavigation and Neuromonitoring in High School and Professional Athletes: Technical Notes, Case Series, and Literature Review
    (2021) Yurac, Ratko; Bravo, José; Silva, Álvaro; Marré, Bartolomé
    Background: Spondylolysis is a defect in the pars interarticularis of the vertebra that occurs frequently in high-performance young athletes. Although nonsurgical management is the mainstay of treatment, surgery is an option for patients with persistent symptoms despite multiple cycles of nonsurgical treatment. Performing a minimally invasive technique reduces complications, postsurgery pain, and hospitalization time and leads to a quick recovery. The aim of this study was to report the clinical results of a series of 3 patients treated with a modification of the Buck technique with a minimally invasive approach. Methods: Three high-performance athletes between 17 and 18 years old who were managed nonsurgically for at least 6 months underwent a modified Buck technique repair with a minimally invasive approach using cannulated compression screws, with neuronavigation and neuromonitoring. Patients were followed at least 6 months with computed tomography scans to assess consolidation and fixation status. Following rehabilitation and in the absence of pain, all 3 athletes returned to their respective sports. No complications were reported. Results: All patients presented with bilateral spondylolysis, at L3 in 1 case and at L5 in 2 cases. Patients received conservative management for 12-36 months before surgery. After surgery, consolidation was obtained at 4 months in all patients, who returned to their sports activities in <6 months. Conclusions: The proposed technique shows the advantages of performing minimally invasive surgery in young high-performance athletes, ensuring consolidation and early return to sports activity without complications.
