Spinopelvic fixation provides a strong fixation for unstable pelvic ring fractures. However, the technique is usually performed with the patient in the prone position, with the applied weight on the anterior superior iliac crests aggravating fracture displacement. We developed a novel approach for minimally invasive percutaneous spinopelvic fixation that is performed with the patient in a lateral (side lying) position. We describe the application of our technique for the treatment of a bilateral pelvic ring and acetabulum fracture in a 79-year-old woman injured in a traffic accident...

STUDY DESIGN: This 2-step prospective randomized parallel trial evaluated postural stability in 65 back pain participants (61.6±7.9 y) and 50 nonback pain participants (61.2±8.6 y) in a first step using the MFT-S3-Check. In a second step, postural stability and questionnaires were evaluated in back pain participants before and after therapy with either whole body vibration therapy or classic physiotherapy. OBJECTIVE: The first aim was to investigate whether the MFT-S3-Check is suitable to evaluate differences in postural stability in back pain and nonback pain participants...

Wearable technology is an exciting industry that has gained exponential traction over the past few years. This technology allows individuals to track personal health and fitness parameters and is becoming more and more precise with modern advancements. As these devices continue to increase in accuracy and gain further utilities in health monitoring, their potential to influence orthopedic care will also grow. Orthopedic surgeons may use this technology to monitor the perioperative course of their patients, who can remotely communicate various parameters related to care without needing to physically be seen by their providers...
