Brief Summary

This prospective, single-center, randomized clinical trial compared the clinical and functional outcomes of hemiarthroplasty performed via lateral versus posterior surgical approaches in elderly patients with displaced intracapsular femoral neck fractures. The primary objective was to compare prosthetic dislocation and intraoperative femoral fracture rates between the two approaches. Secondary outcomes included functional scores, radiological parameters, complications, and mortality.

Conditions

Femoral Neck Fractures; Hip Fractures; Hemiarthroplasty

Keywords

Lateral Hemiarthroplasty; Posterior Hemiarthroplasty; Surgical Approach; Functional Outcome; Harris Hip Score; Parker and Palmer Mobility Score

Outcome Measures

Primary Outcomes (1)

• Prosthetic dislocation rate

  Incidence of postoperative prosthetic hip dislocation following hemiarthroplasty.

  Within 12 months postoperatively

Secondary Outcomes (4)

• Intraoperative periprosthetic femoral fracture rate

  During surgery

• Harris Hip Score (HHS)

  Preoperative baseline and final follow-up at minimum 12 months postoperatively

• Parker and Palmer Mobility Score (PPMS) change

  Preoperative baseline and final follow-up at minimum 12 months postoperatively

• One-year mortality

  Within 12 months postoperatively

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: This study was conducted as an open-label trial. Due to the nature of the surgical interventions, blinding of surgeons and participants was not feasible.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER GOV
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Orthopaedic Surgeon

Model Details: Participants were randomly assigned in a 1:1 ratio to one of two parallel groups to undergo hemiarthroplasty using either the lateral or the posterior surgical approach. Each participant received only the assigned intervention.
