Summary
Femoral fractures after hip arthroplasty, often caused by minimal trauma, require surgical intervention. Treatment involves internal fixation, with some cases needing revision surgery or specialized prostheses.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Ipsilateral femur fractures post-hip arthroplasty present a significant clinical challenge.
- These fractures frequently occur with minimal trauma and are associated with predisposing factors like osteoporosis or prosthesis loosening.
Purpose of the Study:
- To analyze the incidence, characteristics, and treatment outcomes of ipsilateral femur fractures following hip arthroplasty.
- To evaluate the effectiveness of various surgical fixation methods for these complex fractures.
Main Methods:
- Retrospective review of 30 cases of ipsilateral femur fractures after hip arthroplasty between 1979 and 1989.
- Surgical treatment details including fixation with compression plates, intramedullary cement augmentation, and prosthesis revision were analyzed.
Main Results:
- Fractures occurred in 2.3% of primary and 2.9% of revision arthroplasty cases, with a mean patient age of 63 years.
- The majority of fractures (70%) were located below the prosthesis tip.
- Operative treatment was performed in 29 patients, with compression plating being the primary method.
Conclusions:
- Ipsilateral femur fractures after hip arthroplasty are a serious complication requiring surgical management.
- Diverse fixation strategies, including revision arthroplasty, are necessary to address these challenging fractures effectively.
