About the research
The goal of this observational study is to understand how hip function changes over 24 months in adults with minimally displaced femoral neck fractures who are treated without surgery. The study will also describe outcomes for patients who receive surgery as part of their usual clinical care.
Participants will:
- Receive treatment chosen through shared decision-making with their orthopaedic surgeon; the study will not change their clinical care.
- Complete questionnaires about hip function, pain, quality of life, mobility, and daily activities.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- Acute minimally displaced femoral neck fracture, valgus-impacted or nondisplaced
- AO/OTA 31-B1 fracture pattern
- Presentation within 7 days of injury
Exclusion Criteria:
- Displaced femoral neck fracture
- Pathologic fracture
- Periprosthetic fracture
- Open fracture
- Previous ipsilateral femoral neck fracture
- Previous isilateral hip arthroplasty
- Polytrauma
- Delayed presentation to ED
Study population
Patients presenting to Stanford Health Care Emergency Department or Orthopaedic Trauma Clinic

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Non-operative management group

Procedure: Operative management
Non-operative management OTHER

Operative management PROCEDURE
Patient reported outcomes and functional outcomes at 6 weeks, 4 months, 12 months, and 24 months post injury
What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Changes in Modified Harris Hip Score
Time frame: 6 weeks, 4 months, 12 months post injury
Changes from baseline to 12 months. The modified Harris Hip Score (mHHS) is a measure of physical function scored from 0 to 100, where higher scores indicate better physical function and lower scores indicate worse physical function.
Secondary measures
Failure of non-operative management
Time frame: 6 weeks, 4 months, 12 months, 24 months post injury
Failure rate of non-operative management defined as conversion to hemiarthroplasty, or total hip arthroplasty.
Changes in Oxford Hip Score
Time frame: 6 weeks, 4 months, 12 months, 24 months post injury
Changes from baseline to 24 months. The Oxford Hip Score is a measure of physical function scored on the 0 to 48 scale. Each of the 12 items scored 0 to 4, higher scores indicating better physical function and lower scores indicate worse physical function.
Changes in health related quality of life
Time frame: 6 weeks, 4 months, 12 months, 24 months post injury
Changes from baseline to 24 months in EQ-5D-5L. EQ-5D-5L is a patient reported outcome measure to measure health related quality of life scored on a 5 to 25 scale where higher scores indicate worse health status and lower scores indicates better health status.
Changes to Barthel Index
Time frame: 6 weeks, 4 months, 12 months, 24 months post injury
Changes from baseline to 24 months. The Barthel index is a measure of a participant's level of functional independence in basic activities of daily living. It is scored on a 0-100 scale, where higher score indicating higher level of independence and lower score indicating higher level of dependence.
