Abstract:
The use of silicone elastomer implants in podiatric surgical practice is presently a well accepted treatment modality. However, there are instances of failure, and the present study describes a total collapse and fragmentation of a metatarsophalangeal joint prosthesis. Defects are demonstrated by scanning electron microscopy, while physical and chemical reasons for the occurrence as stated in the current literature are reviewed.
