2025 guideline displaced femoral neck fracture total hip arthroplasty versus hemiarthroplasty recommendations
Quick answer
If this is a displaced intracapsular femoral-neck fracture in an older adult, the single best default option is usually bipolar hemiarthroplasty.
Choose total hip replacement (THR/THA) instead only when the patient is a strong, specific candidate: independently mobile outdoors before the fracture, cognitively intact, medically fit for a longer operation, active with a reasonable life expectancy, and ideally has pre-existing symptomatic hip osteoarthritis or inflammatory arthritis.
Why:
- THR can offer a small functional and long-term quality-of-life advantage in selected, active patients.
- But it has more dislocation risk, a longer/more complex operation, and often more blood loss or complications.
- Bipolar hemiarthroplasty is generally quicker, lower risk, and gives reliable pain relief and early weight bearing for the typical frail or lower-demand older patient.
- Recent guidelines align with this: AAOS says THA may provide functional benefit in properly selected displaced fractures but with more complications; NICE recommends considering THA only for independently mobile, medically suitable patients.
So, if forced to pick without individual details: bipolar hemiarthroplasty.
Do not apply that answer to every fracture. In a young patient, or with a nondisplaced fracture, the best treatment may instead be internal fixation. The final surgical choice should account for age, pre-injury mobility, cognition, medical fitness, acetabular arthritis, fracture pattern, and the surgeon/team’s experience.
Evidence includes a 2023 network meta-analysis of 5,703 patients (Ramadanov et al., PMID: 37626370) and the AAOS hip-fracture guideline, which supports THR selectively rather than routinely.

THR/THA vs bipolar hemiarthroplasty for displaced femoral-neck fracture
| Publication | Design and population | Main findings | Practical meaning |
|---|---|---|---|
| Falotico et al., 2025 PMID: 40731418 | Overview of 20 systematic reviews, including about 29,980 patients. Directly assessed THA versus hemiarthroplasty for displaced femoral-neck fracture. | THA had fewer revisions (RR 0.67, 95% CI 0.48-0.93), modestly better early function, and slightly better quality of life. Hemiarthroplasty was about 20 minutes faster. No clear differences in mortality, infection, periprosthetic fracture, or dislocation in the pooled overview. | Best recent synthesis: THA has a long-term functional/revision advantage, but the absolute functional benefit is generally modest. Hemiarthroplasty remains attractive when minimizing operative burden matters. |
| McCafferty et al., 2025 PMID: 40919063 | Methodological systematic review of 9 RCTs reporting no statistically significant difference in reoperation between THA and hemiarthroplasty. | Median reoperation: 5.0% THA vs 7.9% HA. However, the neutral results were statistically fragile: a median of only 3 changed outcomes could alter significance. | This does not prove THA is superior, but it cautions against interpreting earlier "no difference in revision" conclusions as definitive. |
| Ramadanov et al., 2023 PMID: 37626370 | Network meta-analysis of 33 RCTs, 5,703 patients comparing fixation, HA, and THA in displaced and nondisplaced fractures. | THA ranked highest for 2-year quality of life and hip function; HA ranked second. Reoperation risk ranked lowest with THA, then HA. Fixation had less blood loss and shorter operating time. | In arthroplasty candidates, THA tends to optimize function and longer-term survivorship, while HA is less invasive. Results mix displaced and nondisplaced fractures, so do not apply them indiscriminately. |
| Li and Luo, 2021 PMID: 33658055 | Systematic review/meta-analysis of 19 studies, largely observational, with very large administrative-data contribution. | HA had less blood loss, shorter surgery, and fewer dislocations. Mortality, overall complications, reoperation, infection, pulmonary embolism, and MI were not significantly different. | Reinforces the perioperative advantage of hemiarthroplasty, but its pooled population and nonrandomized evidence make it less decisive than the major RCT. |
| HEALTH Trial, Bhandari et al., 2019 PMID: 31557429 | Landmark multicenter RCT: 1,495 independently ambulatory patients aged 50+ with displaced femoral-neck fracture. THA vs HA, 24-month follow-up. | Secondary hip procedures: 7.9% THA vs 8.3% HA, no significant difference. Dislocation/instability: 4.7% THA vs 2.4% HA. Function modestly favored THA but was judged clinically unimportant at 24 months. Mortality was similar. | The highest-quality direct trial supports selective, not routine, THA. Even among independently mobile patients, THA did not materially reduce reoperations at 2 years and carried more instability risk. |
What is actually “new” in trials?
The newest 2025 randomized trial found in the search was about surgical approach for THA (direct anterior versus direct lateral), not THA versus hemiarthroplasty. Therefore, the HEALTH trial remains the largest pivotal direct randomized comparison of THA versus hemiarthroplasty, while the 2025 papers mainly synthesize or reassess the accumulated RCT evidence.
Bottom line from current evidence
| Patient profile | More evidence-supported choice |
|---|---|
| Frail, low-demand, cognitive impairment, limited mobility, major comorbidity, short expected independent-life span | Bipolar hemiarthroplasty |
| Independently mobile outdoors before fracture, medically fit, cognitively intact, active, likely to remain independently functional for over 2 years, especially with pre-existing symptomatic acetabular arthritis | Consider THR/THA |
| General displaced intracapsular fracture without clear “high-function” features | Bipolar hemiarthroplasty is still the safer default |
This matches the NICE recommendation: offer arthroplasty for displaced intracapsular fractures, and consider THA rather than HA only for patients who walked independently outdoors, are medically suitable, and are expected to remain independent in activities of daily living beyond 2 years.
