Acetabular revision with the bipolar prosthesis and particulate bone grafting
Seminars in Arthroplasty
|March 9, 1993
Summary
Bipolar revisions for acetabular defects offer durable reconstructions and excellent function when used with bone grafting and proper implants. This technique remains a viable option for persistent total hip arthroplasty instability.
Area of Science:
- Orthopedic surgery
- Arthroplasty
- Bone reconstruction
Background:
- Porous coated cementless acetabular components are widely successful.
- Acetabular revisions using bipolar prostheses and bone grafting are less common.
- Recalcitrant instability is a challenge in total hip arthroplasty.
Purpose of the Study:
- To evaluate the efficacy of bipolar revisions with particulate bone grafting for acetabular defects.
- To identify indications for bipolar revisions in complex cases.
Main Methods:
- Review of cases involving acetabular revisions with bipolar prostheses and particulate bone grafting.
- Focus on reconstructions for cavitary defects and use of appropriate implants.
Main Results:
- Durable reconstructions with excellent clinical function can be achieved.
- Bipolar revisions are effective when limited to cavitary defects and appropriate implants.
- Persistent instability of total hip arthroplasty is a key indication.
Conclusions:
- Bipolar revisions with bone grafting provide a successful reconstructive option.
- This technique is particularly valuable for specific acetabular defects and persistent instability.
- Clinical outcomes support the durability and functional success of these reconstructions.
