Background Cervical involvement in ankylosing spondylitis (AS) is particularly disabling and has been poorly studied yet. Actual radiologic scoring design to assess disease progression does not provide a comprehensive picture of the cervical AS. [1] Association with clinical features such as psoriasis are discussed. Objectives We aimed radiographic AS clinico-biological parameters associated th...

STUDY DESIGN Comparative assessment of randomized controlled trials of caudal and lumbar interlaminar epidural injections in chronic lumbar discogenic pain. OBJECTIVE To assess the comparative efficacy of caudal and lumbar interlaminar approaches of epidural injections in managing axial or discogenic low back pain. SUMMARY OF BACKGROUND DATA Epidural injections are commonly performed utiliz...

fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...

DESPITE Steindler's (1959) admirable lectures on the subject, pain in orthopiedic practice remains a difficult problem. To some extent the difficulty is exaggerated by the adoption of diagnoses based on pathological processes which are insusceptible of proof-diagnoses for which it is impossible to establish an association between symptoms and their alleged origin, let alone a direct causal link...

BACKGROUND The cervical zygapophyseal joints may be a primary source of pain in up to 60% of individuals with chronic whiplash associated disorders (WAD) and may be a contributing factor for peripheral and centrally mediated pain (sensory hypersensitivity). Sensory hypersensitivity has been associated with a poor prognosis. The purpose of the study was to determine if there is a change in measu...

BACKGROUND One of the potential side effects with radiofrequency ablation (RFA) includes painful cutaneous dysesthesias and increased pain due to neuritis or neurogenic inflammation. This pain may require the prescription of opioids or non-opioid analgesics to control post-procedural pain and discomfort. OBJECTIVES The goal of this study is to compare post-procedural pain scores and post-proc...
