Proximal femoral nail antirotation versus hemiarthroplasty: A study for the treatment of intertrochanteric fractures

Injury, 05/11/2012

Tang P et al. – For elderly patients with intertrochanteric fractures, Proximal femoral nail antirotation (PFNA) was superior to hemiarthroplasty according to the operative statistics, but there were no significant differences in functional outcome.

Methods

  • A retrospective study was performed in the institution, 303 consecutive patients were followed up with mean age of 81.7years.
  • 147 were treated with PFNA, and 156 were underwent hemiarthroplasty.
  • The average follow-up period was 39.9months.
  • The mortality at 1month, 1year, 3years and the total was 6.6%, 18.6%, 27.6% and 30.3%, respectively.

Results

  • There were no significant differences between the groups in terms of demographic data.
  • There were statistical significances in the operative statistics, especially the anaesthesia, operation lasting time, blood loss, blood transfusion and the drainage.
  • There was no significant difference in Harris Hip Score between PFNA and hemiarthroplasty group, but the detail items were quite different.
  • Significant difference was found in the excellent-to-fine rate (PFNA 90.2% and hemiarthroplasty 79.6%).
  • Complications occurred in 34 patients, although incidences of complications were higher in hemiarthroplasty group (14.1% vs. PFNA 8.96%), no statistical difference was found.
