[Incidence of pelvic and acetabular fractures in the elderly due to high energy trauma].

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.

Results: a cumulative incidence of 1.

[Functional evaluation with the KSS (Knee Society Score) scale at 3 and 6 months after ligament reconstruction in patients with multi-ligament knee injuries in a third level hospital].

Multiligament injuries of the knee joint are characterized by the involvement of two or more major ligaments, anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), lateral collateral ligament (LCL), posteromedial corner (PMC) and posterolateral corner (PLC). Statistically, multiligament injuries are rare as they are found in less than 0.02% of all traumatic knee injuries; however, different aggregate injuries are what make this pathology a serious health and functional condition.

Personalized Interventional Surgery of the Lumbar Spine: A Perspective on Minimally Invasive and Neuroendoscopic Decompression for Spinal Stenosis.

Pain generator-based lumbar spinal decompression surgery is the backbone of modern spine care. In contrast to traditional image-based medical necessity criteria for spinal surgery, assessing the severity of neural element encroachment, instability, and deformity, staged management of common painful degenerative lumbar spine conditions is likely to be more durable and cost-effective. Targeting validated pain generators can be accomplished with simplified decompression procedures associated with lower perioperative complications and long-term revision rates.
