Bilateral total hip arthroplasty: a simultaneous procedure
Insights
Bilateral total hip replacement is feasible but carries increased risks like phlebitis and myositis ossificans compared to unilateral procedures. Patients experienced longer hospital stays but similar mortality rates.
Area of Science:
- Orthopedic Surgery
- Arthroplasty Research
Background:
- Total hip replacement is a common procedure for hip joint issues.
- Simultaneous bilateral total hip replacement offers potential benefits but requires careful risk assessment.
Purpose of the Study:
- To compare the outcomes of simultaneous bilateral total hip replacement with unilateral total hip replacement.
- To evaluate the feasibility and associated risks of bilateral hip arthroplasty.
Main Methods:
- A comparative study involving 50 patients undergoing bilateral total hip replacement and 50 patients undergoing unilateral total hip replacement.
- Data collected included complications, range of motion, mortality, hospital stay, operating time, and blood loss.
Main Results:
- Bilateral hip replacement showed increased rates of phlebitis and myositis ossificans.
- Patients in the bilateral group had reduced range of motion, longer hospital stays (average 1 week longer), and approximately double the operating time and blood loss.
- No significant difference in mortality was observed between the groups, with one death in each.
- Notably, no infections were reported in the bilateral group.
Conclusions:
- Simultaneous bilateral total hip arthroplasty is feasible.
- This procedure is associated with a slightly increased risk profile compared to unilateral hip replacement.
Abstract:
Fifty patients undergoing bilateral total hip replacement as a simultaneous procedure at the Indiana University Medical Center were compared with 50 patients undergoing unilateral total hip replacement. There was an increase in phlebitis and myositis ossificans in the patients undergoing bilateral total hip replacement and while their range of motion was less, there was no difference in mortality with one death in each group. The hospital time for patients in the bilateral group averaged 1 week longer than for those with unilateral hip replacement. The operating time and blood loss in patients of the bilateral group was approximately twice that of patients in the control group. There have been no infections as yet in the bilateral group. On the basis of these preliminary results, we can consider bilateral total hip arthroplasty feasible although it carries a slightly increased risk.
