[Arthroplasty of the hip using a double cup]

|October 1, 1981
Summary
This double-cup arthroplasty, cementing only the acetabular cup, shows promising results for hip osteoarthritis. It effectively manages pain and improves mobility, with complications comparable to traditional methods.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
Context:
- Hip arthroplasty is a common procedure for debilitating hip conditions.
- Traditional total hip prostheses involve cementing both acetabular and femoral components.
- A double-cup arthroplasty technique, where only the acetabular cup is cemented, has been developed.
Purpose:
- To evaluate the efficacy and safety of a double-cup arthroplasty technique.
- To assess complication rates, radiographic outcomes, and functional results.
- To determine the suitability of this technique for specific patient populations.
Summary:
- The study involved 67 hips undergoing double-cup arthroplasty with acetabular cup cementing only.
- Complications included dislocation, cement seal issues, ossification, and femoral neck fracture, with overall rates comparable to traditional methods.
- Follow-up in 45 cases for at least one year showed frequent but non-alarming X-ray signs of injury.
- Pain relief and mobility improvement were comparable to total hip prostheses, especially in stiff hips.
Impact:
- This double-cup arthroplasty offers comparable pain relief and mobility to total hip prostheses.
- It is indicated for hip osteoarthritis in patients aged 40-65 unresponsive to conservative treatment or unsuitable for osteotomy.
- Crucially, the technique preserves options for future total hip replacement surgery.
