Abstract
Purpose
The main purpose of this study was to compare the outcome of total hip arthroplasty (THA) via the direct anterior approach (DAA) using a dual-mobility cup (DMC) in patients with femoral neck fracture to those in patients undergoing elective THA for osteoarthritis.
Patients and methods
We retrospectively investigated 40 hips with femoral neck fracture (group A), and 81 hips with osteoarthritis (group B). THA via the DAA using the DMC was performed in both groups. A primary/secondary outcome variable were the presence of dislocation/operative time, intra- and/or peri-operative complication, and mortality.
Results
Dislocation did not occur in either group. The complication rate was slightly higher in group A than in group B, but not statistically significant.
Conclusion
THA with the DMC using the DAA was as effective for femoral neck facture as it was for elective THA in patients with osteoarthritis.
