Key result
Total hip arthroplasty and hemiarthroplasty linked to ~86% fewer major reoperations versus internal fixation.
Why the study?
The optimal treatment for patients aged 55 to 70 years with displaced intracapsular femoral neck fracture remains controversial.

Comparison
Internal fixation vs bipolar hemiarthroplasty vs total hip arthroplasty

Does arthroplasty (HA or THA) improve outcomes compared to internal fixation in patients aged 55-70 with displaced femoral neck fractures?
Absolute Event Rate: 2.8% vs 27%
In patients aged 55-70 with displaced femoral neck fractures, arthroplasty (THA or HA) is associated with significantly lower reoperation rates and better patient-reported outcomes compared to internal fixation.
Bartels et al. (2017) conducted a cohort in Displaced intracapsular femoral neck fracture (n=2,713). Total hip arthroplasty (THA) vs. Internal fixation (IF) was evaluated on Major reoperations. Total hip arthroplasty (2.8%) and hemiarthroplasty (3.8%) were associated with lower major reoperation rates compared to internal fixation (27%) for displaced femoral neck fractures.
