Is primary chronic osteomyelitis a uniform disease? Proposal of a classification based on a retrospective analysis of patients treated in the past 30 years.

What Researchers Did

Researchers retrospectively analyzed 30 cases of primary chronic osteomyelitis of the jaw to establish a clinical classification based on patient data.

What They Found

The study analyzed 30 cases, finding a mean age of onset of 35 years (range 5-76 years) with incidence peaks in adolescence and after age 50. Six patients (five adults, one adolescent) presented with additional non-facial manifestations consistent with SAPHO syndrome, and microabscesses were noted in 11 cases.

Canadian Relevance

This study has no direct Canadian connection as it was conducted in a different geographical region.

Study Limitations

The study's retrospective design, small sample size of 30 cases, and single-center origin limit the generalizability of its findings.
