title: The Fixion expandable stem hemiarthroplasty for displaced femoral neck fracture: technical features and pilot study.
abstract: BACKGROUND
  Management of displaced femoral neck fracture in elderly patients is challenging due to the patient's high risk profile, poor quality bone stock and muscle weakness.
  
  
  METHODS
  Fifty-one patients with displaced (Garden 3-4) intracapsular femoral neck fractures were treated with a newly designed Fixion expandable stem hemiarthroplasty implant and followed thereafter for a minimum of 6 months.
  
  
  RESULTS
  Thirty patients (58.8%) had concomitant diseases graded 3-4 by the ASA scoring system. Two patients (4.8%) incurred deep wound infections that necessitated hardware removal. One case (2.6%) of dislocation was treated by closed reduction. Forty-two patients (82.4%) survived >6 months and cooperated with the study protocol. Mild groin/thigh pain was reported by 11 patients (26.2%). Twenty-six (61.9%) had lost 1-2 out of 4 grades of mobility.
  
  
  CONCLUSIONS
  Fixion implant may be considered a further step in the evolution of femoral joint hemiarthroplasty. In the short term, it has proven to be as effective as cemented implant and to be user-friendly for the surgeon. It is also anticipated to be feasible whenever revision is required.
