What Researchers Did
The researchers reviewed their experience with an experimental rat model for femoral head osteonecrosis and various therapeutic options tested using this model.
What They Found
They found that incising the periosteum and cutting the ligamentum teres in rats consistently induced coagulation necrosis of the femoral epiphysis, leading to an osteoarthritis-like disorder. The necrotic tissue was progressively replaced by architecturally abnormal and biomechanically weak bone. Six diverse therapeutic options were studied using this model, including hyperbaric oxygen, enoxaparin, and core decompression.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a review of an animal model, the direct applicability of these findings to human patients is limited due to physiological differences between rats and humans.
