Summary
Dislocation is a common reason for total hip arthroplasty revision. Specific factors like femoral head size and surgical approach increase dislocation risk, while specialized liners do not significantly reduce it.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Arthroplasty Research
Background:
- Dislocation following total hip arthroplasty (THA) is a frequent cause for revision surgery.
- Understanding the characteristics of hips revised for dislocation is crucial for improving patient outcomes.
Purpose of the Study:
- To determine the characteristics of revision THA specifically for dislocation.
- To identify typical features associated with hips revised due to dislocation.
Main Methods:
- Prospective multicenter study involving 30 centers.
- Included first revision THA cases performed between January 1, 2010, and December 31, 2011.
- Excluded multiple revisions.
Main Results:
- Dislocation accounted for 10.4% of first revision THA (219 cases).
- Predictive risk factors included a 22.2mm femoral head, posterolateral approach, older age, and elevated rim liners.
- Dual mobility cups showed no significant difference in revision rates for dislocation compared to flat rim liners.
Conclusions:
- The observed rate of THA revision for dislocation is lower than reported in existing literature.
- Elevated rim or constrained liners did not demonstrate improved outcomes in preventing dislocation compared to standard liners.
