Does diagnostic cervical zygapophyseal joint block for chronic cervical pain?
The prevalence of cervical zygapophyseal joint pain estimated in this clinical study is lower than that found in previous research setting studies, but our requirement for confirmation by a repeat block (which many patients declined) makes our estimate conservative; it is likely that the true prevalence is higher. Zygapophyseal joints are clearly a common source of pain in patients presenting with chronic neck pain, with or without headache. Cervical zygapophyseal joint pain is readily diagnosable, enabling patients to seek further, targeted treatment.
The WBC, ESR, and jWBC are extremely variable in adults with septic arthritis. Laboratory tests do not rule out septic arthritis with accuracy.
