Epidemiology
Coccygodynia is rare, and accounts for approximately 1% of patients presenting with musculoskeletal or spinal pain.[3] Concomitant low back pain is reported in up to 77% of cases.[4] True incidence in the US and globally is unknown, as coccygodynia is an under-recognized clinical entity. The male-to-female ratio is 1:5.[5][6] There are no known epidemiologic differences with respect to ethnicity. The mean age of onset is 40 years, but it can occur at any age.[7][8] Most cases are post-traumatic (60% to 70%), the rest are nontraumatic or idiopathic (30% to 40%).[5][7][8]
