The literature describes the presence of intra-articular structures in the zygapophyseal (facet) joint (Bogduk & Engel 1984, Bogduk 1997). The largest of these structures is attached via synovium to the inner surface of the superior and inferior capsules. They project up to 5mm into the joint space. The apex of these structures is wedge-shaped and consists of densely packed collagen. Their func...

Thoracic posterior joints are putative pain generators; yet there is a paucity of information to assist the clinician in the diagnosis and treatment of dorsal spine pain. A safe and effective bent needle injection/arthrography technique is described which can assist in the diagnosis of some patients with thoracic zygapophyseal joint dysfunction.

OBJECTIVES: The aim of this study was to investigate the efficacy of ultrasound as a guiding tool for simulated cervical facet joint injections in cadavers. METHODS: A total of 40 ultrasound examinations at 5 levels (C6-7 to C2-3) were performed on 4 embalmed cadavers. The zygapophyseal joints were located with ultrasound. First, the transverse processes of C6 and C7 were established and the fa...

background & aim: lumbar spinal stenosis (lss) is a common condition. this congenital or acquired stenosis has multiple etiologies. the goal of this study was to describe intraoperative pathoanatomic findings of lumbar spinal stenosis observed within a black african population. methods & materials/patients: it was a retrospective and descriptive study performed at departmental teaching hospital...

conclusions a new approach to treat lumbar facet joint pain with prf is simple to perform and without serious complications. in view of the good long-lasting results obtained with the two reported cases, randomized control trials are necessary to validate this new approach. case presentation a 71-year-old patient presented because of persisting pain in the left gluteal region radiating to the l...

BACKGROUND In spite of the widespread performance of intra-articular zygapophyseal joint (IAZJ) injections, we know of no systematic analysis to date that examines the risks and types of adverse events when IAZJ injections are performed. OBJECTIVE To describe the type, incidence, and factors contributing to adverse events associated with fluoroscopically guided IAZJ injections. STUDY DESIGN...

The aim of this study was to investigate whether bilateral widespread pressure hypersensitivity exists in patients with unilateral carpal tunnel syndrome. A total of 20 females with carpal tunnel syndrome (aged 22-60 years), and 20 healthy matched females (aged 21-60 years old) were recruited. Pressure pain thresholds were assessed bilaterally over median, ulnar, and radial nerve trunks, the C5...
