Crystalline arthropathy and bone health.

PURPOSE OF REVIEW

The purpose of this review is to provide insight on the proposed association between crystal arthritis and bone health. Crystal arthritis is the most common type of inflammatory arthritis, and fractures contribute to significant morbidity and mortality, therefore, the relationship between the two is of clinical importance.

RECENT FINDINGS

There have been variable findings regarding hyperuricemia, low bone density and risk of fracture. A recent systematic review and meta-analysis of available literature showed a correlation between increased serum uric acid and lower risk of fracture. Less is known about calcium pyrophosphate deposition disease and bone health, although two large studies have suggested an association with osteopenia.

SUMMARY

A systematic review and meta-analysis of available data suggest a correlation between increased serum uric acid and lower risk of fracture. Findings support an association between bone health and crystal arthritis which warrants further study and may have implications for how we treat gout.
