Objectives: To demonstrate the recovery of lumbar sagittal pelvic alignment and sagittal pelvic balance after surgical reduction of lumbar spondylolisthesis and establish the benefits of the surgery for reduction and fixation of the lumbar spondylolisthesis with 360o circumferential arthrodesis for 2 surgical approaches by clinical and functional evaluation. Method: Eight patients with lumbar spondylolisthesis treated with surgical reduction and fixation of listhesis and segmental circumferential fusion with two surgical approaches were reviewed. They were evaluated before and after treatment with Oswestry, Visual Analogue for pain and Odom scales, performing radiographic measurement of lumbar sagittal alignment and pelvic sagittal balance with the technique of pelvic radius. Results: Oswestry scales and EVA reported improvement of symptoms after treatment in 8 cases; the Odom scale had six outstanding cases reported. The lumbar sagittal alignment presented a lumbosacral lordosis angle and a lumbopelvic lordosis angle reduced in 4 cases and increased in 4 other cases; pelvic sagittal balance increased the pelvic angle in 4 cases and decreased in 3 cases and the sacral translation of the hip axis to the promontory increased in 6 cases. Conclusion: The surgical procedure evaluated proved to be useful by modifying the lumbar sagittal alignment and the pelvic balance, besides reducing the symptoms, enabling the patient to have mobility and movement and the consequent satisfaction with the surgery.
Purpose: During the coronavirus disease 2019 pandemic, Colombian government declared a lockdown, forcing children to stay at home. The authors aimed to analyze the change in the pattern of trauma-related visits during the lockdown.Methods: We carried out a retrospective descriptive study on injured children aged 17 years or younger who visited the emergency department of a tertiary pediatric hospital in Bogotá, Colombia from March 15 through May 15, 2019 (control period) and the same period in 2020 (lockdown period). Between the 2 periods, baseline characteristics and injury profiles were compared.Results: Among the study population (n = 1,485), 1,122 and 363 children visited the emergency department during the control and lockdown periods, respectively. In the midst of 73.9% decrease in numbers of overall visits between the 2 periods, a 67.6% decrease was noted in number of trauma-related visits. Regarding the proportions, trauma-related visits increased from 7.9% to 9.8%. During the lockdown, increases occurred in the proportions of the following variables: children younger than 5 years (25.5% to 50.7%; P < 0.001), mechanisms other than blunt, minor fall or traffic accident (e.g., bite, 3.9% to 6.6%; P = 0.032), child abuse (1.2% to 4.1%; P = 0.003), hospitalization (4.6% to 35.8%; P < 0.001), open wound (21.1% to 36.9%; P < 0.001), the use of computed tomography (6.3% to 9.9%; P < 0.001), and abnormal imaging findings (28.8% to 31.7%; P = 0.003).Conclusion: During the lockdown, children with trauma may show an increase in overall severity, and also a higher risk of abusive trauma. This finding indicates a sensible need of educating families in prevention of domestic injury.
Este número especial nace a partir de dos iniciativas desarrolladas en el IX Encuentro de Teoría Arqueológica de América del Sur (taas), realizado en Ibarra, Ecuador, en junio del 2018. Las iniciativas reflexionan sobre diversos enfoques metodológicos e interpretaciones destinadas a cuestionar el uso de la autoridad arqueológica y la autenticidad etnográfica como medios para legitimar la lógica de colonialidad dominante en América Latina. A partir de una reflexión conjunta sobre la situación y proyección de la teoría y la práctica arqueológica y sus implicancias en el Sur de América, los encuentros iniciados por el taas han propiciado más espacios de diálogo e intercambio entre instituciones, colectivos, comunidades y academias. Estos espacios, que hace más de dos décadas no tenían la misma llegada ni sincronía con otros eventos científicos, se han vuelto lugares comunes y se han mantenido latentes, potenciados a su vez gracias a los grandes cambios que vivimos actualmente en Latinoamérica y el mundo.
