This document summarizes the case of a 49-year-old Thai female patient who presented with left hip pain for 5 hours after falling from her motorcycle. Examination revealed tenderness and limited range of motion of the left hip with shortening and external rotation of the left leg. X-rays showed a displaced Garden IV femoral neck fracture. The document then reviews femoral neck fracture epidemiology, anatomy, signs and symptoms, investigations, classification systems, management options including fixation versus arthroplasty depending on patient age and fracture characteristics, and potential complications.
