Avascular Necrosis of Femoral Head
Geriatric Orthopaedic Surgery & Rehabilitation, 2013 Avascular necrosis (AVN) of the femoral head is a relatively uncommon complication following an extracapsular hip fracture. Although it can occur following fixation of unstable 3-part or 4-part intertrochanteric fractures with significant posteromedial ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
