Technique for Lateral Opening Wedge Distal Femoral Osteotomy Using Patient‐Specific Instrumentation for Genu Valgum and Patellar Instability

Arthroscopy Techniques, EarlyView.
Abstract Recurrent lateral patellar instability poses a technical challenge to orthopaedic surgeons. Isolated soft‐tissue procedures through medial patellofemoral ligament reconstruction or lateral release show unacceptably high failure rates. Lateral opening wedge distal femoral osteotomy addresses underlying bony malalignment and reinforces the soft ...

Use of Free Flaps in the Reconstruction of the Ventral Skull Base: A Systematic Literature Review

Head &Neck, EarlyView.
ABSTRACT Background Reconstruction of the ventral skull base represents a challenge in head and neck surgery. When local or regional flaps are insufficient, microvascular free flaps offer a reliable reconstructive option. Methods A systematic literature review was conducted following PRISMA guidelines to identify studies on ventral skull base ...
