A typical clinical course of failed internal fixation in middle-aged patient. a A 56-year-old male patient with history of alcohol consumption sustained a left displaced femoral neck fracture. b Three cannulated screws were applied within 6 h and acceptable reduction was achieved. c Postoperative 6 months, there was still non-union with screw backout. d Screws were removed and hemiarthroplasty was performed. The case highlighted a common but catastrophic course of middle-aged patients with FNFs, even good reduction was achieved during primary fixation
