The AO Principles of Fracture Management Mission The AO’s mission is promoting excellence in patient care and outcomes in trauma and musculoskeletal disorders. AO Principles 1,2 1 Fracture reduction and ﬁxation to restore anatomical relationships. 2 3 4 Fracture ﬁxation providing absolute or relative stability, as required by the “personality” of the fracture, the patient, and the injury. Preservation of the blood supply to soft-tissues and bone by gentle reduction techniques and careful handling. Early and safe mobilization and rehabilitation of the injured part and the patient as a whole. Intended Use, Indications and Contraindications, Adverse Events Intended Use The Femoral Neck System (FNS) is intended for temporary ﬁxation, correction or stabilization of bones in the femoral neck. Indications • Femoral neck fractures (AO type 31-B) Contraindications • Pertrochanteric fractures (AO type 31-A1 and 31-A2) • Intertrochanteric fractures (AO type 31-A3) • Subtrochanteric fractures Additionally, this system should not be used for cases where there is a high incidence of: • Sepsis • Malignant primary or metastatic tumors • Material sensitivity • Compromised vascularity Adverse Events As with all major surgical procedures, risks, side effects and adverse events can occur. While many possible reactions may occur, some of the most common include: Problems resulting from anesthesia and patient positioning (e.g. nausea, vomiting, dental injuries, neurological impairments, etc.), thrombosis, embolism, infection, excessive bleeding, iatrogenic neural and vascular injury, damage to soft tissues incl. swelling, abnormal scar formation, functional impairment of the musculoskeletal system, Sudeck’s disease, allergy/hypersensitivity reactions and side effects associated with hardware prominence, malunion, non-union, device breakage, device loosening. Additional device speciﬁc adverse events that may occur: Pain, device migration (e.g. wire migration and penetration into the pelvic cavities), bone damage and bone fracture. 3
