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

Study population

The study population will consist of adult patients undergoing hemiarthroplasty for displaced femoral neck fracture at Meir Medical Center during the study period.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Adults aged 18 years or older Patients undergoing hemiarthroplasty (partial hip replacement) during the study period at Meir Medical Center Ability to provide for participation in the study

Exclusion criteria

Exclusion Criteria:

Revision surgery performed during the index hospitalization Inability to complete postoperative follow-up Inability to provide (e.g., dementia or presence of a legal guardian) Pre-injury mobility status of bedbound or wheelchair-bound Polytrauma patients Prior fixation or arthroplasty of the contralateral hip within the previous year

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for May 2026; primary completion for May 2028, 24 months later.

Of 20 observational studies under Femoral Neck Fractures, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 120. This study's planned 24 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 30, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
