Clinical and Functional Outcomes of Lateral vs Posterior Hemiarthroplasty

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.

About this study

This study is a prospective, single-center, randomized clinical trial designed to compare the clinical, functional, and radiological outcomes of hemiarthroplasty performed via lateral and posterior surgical approaches in elderly patients with displaced intracapsular femoral neck fractures.

Between March 2016 and June 2019, eligible patients were randomized in a 1:1 ratio to undergo hemiarthroplasty using either the lateral or posterior approach. Randomization was performed using a computer-generated sequence. All procedures were performed or supervised by experienced orthopedic surgeons following standardized surgical and postoperative protocols.

Clinical parameters, perioperative data, and radiological indices including cortical index, Singh index, and Dorr classification were recorded. Functional outcomes were assessed using the Parker and Palmer Mobility Score (PPMS) and the Harris Hip Score (HHS). Patients were followed for a minimum of 12 months.

The primary outcome measure was the prosthetic dislocation rate within 12 months postoperatively. Secondary outcomes included intraoperative periprosthetic femoral fracture rate, functional scores, complications, and mortality. The study was conducted in accordance with the principles of the Declaration of Helsinki, with approval obtained from the local ethics committee, and written informed consent was obtained from all participants or their legal representatives.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age 60 years or older
  • Displaced intracapsular femoral neck fracture
  • Treated with hemiarthroplasty
  • Ability to provide informed consent by the patient or a legal representative

Exclusion criteria

  • Pathological femoral neck fractures
  • Previous surgery on the affected hip
  • Polytrauma patients
  • Periprosthetic fractures

Treatment and study plan

Posterior approach hemiarthroplasty

Procedure

Hemiarthroplasty performed using the posterior surgical approach.

Lateral approach hemiarthroplasty

Procedure

Hemiarthroplasty performed using the lateral surgical approach.

Primary outcomes

  1. Prosthetic dislocation rate

    Time frame: Within 12 months postoperatively

    Incidence of postoperative prosthetic hip dislocation following hemiarthroplasty.

Secondary outcomes

  1. Intraoperative periprosthetic femoral fracture rate

    Time frame: During surgery

    Incidence of intraoperative femoral fractures occurring during hemiarthroplasty.

  2. Harris Hip Score (HHS)

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

    The Harris Hip Score is a clinician-based outcome measure ranging from 0 to 100 points, where higher scores indicate better hip function.

  3. Parker and Palmer Mobility Score (PPMS) change

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

    The Parker and Palmer Mobility Score is a validated mobility assessment scale ranging from 0 to 9 points, where higher scores indicate better mobility.

  4. One-year mortality

    Time frame: Within 12 months postoperatively

    All-cause mortality within one year after surgery.
