METHODS: The study population was 48 patients; the orthopedic defect site was located on the right side in 22 and on the left side in 26 cases. The graft material was antigen-free equine-derived collagen bone cleaned with an enzymatic treatment.
RESULTS: Clinical and radiographic healing times were virtually similar; graft osseointegration needed from two to three months longer to heal.
CONCLUSION: The outcome after grafting with an equine-derived bone substitute was satisfactory. Further study is needed to demonstrate its statistically significant effectiveness in the treatment of orthopedic defects like those in this series.
