Dislocation after hip hemiarthroplasty in elderly patients occurred in 6% of cases, often within 19 days. Male sex, mental disease, and smaller femoral neck offset were key risk factors.

Area of Science:

  • Orthopedic Surgery
  • Geriatric Medicine
  • Biomedical Engineering

Background:

  • Hip fractures are common in the elderly, often requiring surgical intervention.
  • Modular unipolar hemiarthroplasty is a common treatment for hip fractures in elderly patients.
  • Post-operative dislocation of hemiarthroplasty implants can lead to significant morbidity.

Purpose of the Study:

  • To identify clinical and radiographic factors predisposing to dislocation after modular unipolar hemiarthroplasty in elderly patients.
  • To analyze the incidence and timing of hemiarthroplasty dislocation.
  • To investigate the association between dislocation and patient mortality.

Main Methods:

  • Retrospective review of 217 elderly patients undergoing hip hemiarthroplasty with a modular unipolar implant.

  • Evaluation of dislocation versus nondislocation as the primary outcome measure.
  • Analysis of clinical data (sex, mental disease) and radiographic parameters (femoral neck offset, center edge angle).

    • Main Results:

    • The overall incidence of dislocation was 6%, with an average time to dislocation of 19.3 days post-surgery.
    • Significant clinical predictors for dislocation included male sex and pre-existing mental disease.
    • Radiographic findings associated with dislocation were a smaller femoral neck and contralateral femoral neck offset, and a smaller center edge angle.
    • Patients experiencing dislocation had a higher mortality rate.

    Conclusions:

    • Male sex, mental disease, and specific radiographic parameters like smaller femoral neck offset are significant risk factors for hemiarthroplasty dislocation in the elderly.
    • Early identification of these risk factors may aid in surgical planning and patient selection to reduce dislocation rates.
    • Hemiarthroplasty dislocation in this population is associated with increased mortality, underscoring the importance of implant stability.
