Summary
The Mennen plate offers a reliable internal fixation for fractures around hip and shoulder joint replacements. This technique showed satisfactory outcomes in most patients, even with severe bone loss or multiple revisions.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
- Radiology
Background:
- Fractures and aseptic loosening are complications following hip and shoulder joint replacements.
- Severe bone loss can complicate these fractures, necessitating advanced fixation techniques.
Purpose of the Study:
- To evaluate the efficacy of Mennen plate fixation for fractures associated with hip and shoulder joint replacements.
- To assess outcomes in patients with severe bone loss and aseptic loosening.
Main Methods:
- Internal fixation using the Mennen plate was performed on 18 patients with femoral or humeral fractures.
- Some patients also underwent revision joint replacement or bone grafting.
- Outcomes were assessed based on functional activity, pain, and radiographic evaluation.
Main Results:
- Satisfactory results were achieved in 15 out of 18 patients.
- Improvements in function, pain, and radiographic appearance were noted.
- While unsatisfactory in three patients with multiple revisions, their status improved compared to pre-operation.
Conclusions:
- Mennen plate fixation is a sufficient and straightforward technique for fractures near or below the stem in hip and shoulder joint replacements.
- For unstable femoral fractures or aseptic loosening with significant bone loss, Mennen plate fixation combined with long-stem revision total hip replacement and bone grafting is recommended.
