Study summary

The goal of this clinical trial is to learn whether the surgical approach used for hemiarthroplasty can improve clinical and functional outcomes in adults with displaced femoral neck fractures.

The main questions it aims to answer are:

  • Does the direct anterior approach (DAA) result in superior postoperative functional recovery compared with the direct lateral approach (DLA)?
  • Are mortality, complications, hospital utilization, and readmission rates different between the two surgical approaches? Researchers will compare hemiarthroplasty performed using the direct anterior approach to hemiarthroplasty performed using the direct lateral approach to determine whether surgical approach influences postoperative function, complications, and survival.

Participants will:

  • Undergo hemiarthroplasty for displaced femoral neck fracture using a randomly assigned surgical approach (DAA or DLA)
  • Complete a baseline functional assessment using the Activities of Daily Living (ADL) questionnaire before surgery
  • Have perioperative data collected during hospitalization, including laboratory values, operative details, blood loss, transfusions, analgesic use, complications, length of stay, and in-hospital mortality
  • Attend follow-up clinic visits at 6 weeks and 3 months after surgery
  • Complete postoperative functional assessment using the Harris Hip Score at both follow-up visits
  • Have demographic data, complications, readmissions, and mortality monitored through review of electronic medical records

What researchers measure

Primary outcomes

  1. Harris Hip Score (HHS) - Postoperative Functional Outcome at 6 Weeks and 3 Months Following Hemiarthroplasty

    Functional outcome will be assessed using the Harris Hip Score (HHS), a validated 100-point scale evaluating pain, function, deformity, and range of motion, collected at 6 weeks and 3 months postoperatively.

    Time frame: 6 weeks and 3 months post-surgery

Secondary outcomes

  1. Incidence of Treatment-Related Complications Following Hemiarthroplasty

    Number of participants with one or more complications- Including intraoperative blood loss, blood transfusions, implant dislocation, implant failure, surgical site infection, and other adverse events.

    Time frame: During hospitalization and up to 3 months post-surgery
