INTRODUCTION AND AIM: Minimally invasive surgery (MIS) of the spine prevents the collapse of osteoporotic vertebral fractures (OVF) with lower complication and bleeding rates than open surgery. However, the possibility of hidden blood loss (HBL) has been recently described, referring to the loss of blood diffused into tissues and lost through hemolysis. This study aimed to estimate the postoperative impact of HBL in patients undergoing MIS for OVF. MATERIALS AND METHODS: This was a retrospective study of a series of patients who had MIS for OVF...

INTRODUCTION: as the population pyramid gets inverted, more active and longer lives are lived, geriatric patients with high energy trauma (HET) become more frequent; requiring more resources, getting worse results with more perioperative complications, coupled with a fragile state of health and osteopenia, make these fractures difficult to manage. With the hypothesis that the incidence of pelvic and acetabular fractures in the elderly due to HET is higher than that reported in the world literature, the research question was generated: What is the incidence of pelvic and acetabular fractures in the elderly due to HET, in a 5-year period? MATERIAL AND METHODS: with the authorization of the Ethics Committee, an observational study of a retrospective cohort was carried out, using medical records, identifying the incidence of these fractures, surgically treated in our institution Clínica Las Vegas, Medellin, Colombia, a level III hospital, from July 1, 2016 to June 30, 2021...

UNLABELLED: Bone as a material varies its composition and mechanical properties throughout life. Although these variations are better understood in adulthood, there is little experimental information on the variation of these properties in early stages of development. The objective of this study is to analyze the mechanical behavior and chemical properties of cortical bone tissue from two animal species in these earliest stages. MATERIAL AND METHODOLOGY: Twenty specimens of cortical bone were manufactured from bovine and ovine species that were in different stages of development (feeding exclusively on breast milk, in the transition period to feed or pasture, and young animals but on a solid food diet)...

BACKGROUND: The World Health Organization (WHO) declared COVID-19 a pandemic on March 11, 2020. Patients who tested positive for COVID-19 experienced a higher overall rate of post-surgical complications and hospital mortality. OBJECTIVE: To compare the asociation of post-surgical complications presented in post-surgical hip patients with and without history of COVID-19 infection. MATERIAL AND METHODS: Prospective cohort study. The inclusion criteria were: post-hip surgery adults with and without a history of COVID-19 infection who attended their post-surgical follow-up consultation...

OBJECTIVE: Description and analysis of the relation between the proximal humerus fracture patterns and the traumatic injury of the axillary nerve. Material and method Prospective, observational study of a consecutive case series that analysed proximal humerus fractures. Radiographic evaluation was performed, and AO (Arbeitsgemeinshaft für Osteosynsthesefragen) system was used to classify the fractures. Electromyography was used to diagnose the axillary nerve injury. RESULTS: Thirty-one patients on 105 who had a proximal humerus fracture met inclusion criteria...

BACKGROUND AND OBJECTIVE: Synthesis with cannulated screws is one of the accepted methods in femoral neck fractures, although its optimal configuration is a subject in continuous debate. The main objective was to compare the results of the patient with a femoral neck fracture fixed with three screws in triangle and inverted triangle configuration in the frontal plane. MATERIALS AND METHODS: Retrospective and comparative study of 53 patients with femoral neck fracture, operated between 2015 and 2022 with fixation with three cannulated screws, 22 with a triangle configuration (triangle group) and 31 in an inverted triangle (inverted triangle group)...

INTRODUCTION: Tibial plateau fractures are injuries prone to postoperative infection, with its reported incidence being higher than that of other fractures, between 5% and 12%.
