BACKGROUND: Osteoarthrosis of the lateral atlanto-axial joint (LAAJ) may be a cause of upper neck pain and headache. Intra-articular injection of steroids may provide only short-lasting relief. For intractable pain, arthrodesis of the joint might be considered. OBJECTIVE: To determine the success rates of arthrodesis of the lateral atlanto-axial joint for relieving neck pain and disability. DESIGN: Practice audit. SETTING: Private practice of senior author...

PURPOSE: To investigate the innervation pattern of the sacroiliac region, especially with regard to the sacroiliac joint (SIJ). Dorsal SIJ innervation was analyzed and described. Our main hypothesis was that nerves reach the SIJ dorsally, passing ligamental compartments, as this would explain dorsal SIJ pain. METHODS: To examine sacroiliac innervation, we followed the nerves in over 50 specimens over several years. Plastinated slices were evaluated, nerves in the region were stained histologically, and the data were summarized as 3D models...

BACKGROUND: Estimates of the prevalence of lumbar zygapophysial joint (Z joint) pain differ in the literature, as do case definitions for this condition. No studies have determined the prevalence of "pure" lumbar Z joint pain, defined as complete relief of pain following placebo-controlled diagnostic blocks. OBJECTIVE: The objective of this study was to estimate the prevalence of "pure" lumbar Z joint pain. METHODS: In a private practice setting, 206 patients with possible lumbar Z joint pain underwent controlled diagnostic blocks using one of two protocols: placebo-controlled comparative blocks and fully randomized, placebo-controlled, triple blocks...

OBJECTIVES: The study sought to assess the utility of controlled diagnostic blocks in patients with probable cervicogenic headache by determining the prevalence of sources of pain among the upper and lower synovial joints of the cervical spine. METHODS: Controlled diagnostic blocks were performed in 166 consecutive patients who clinically exhibited features consistent with a diagnosis of probable cervicogenic headache. Data were collected on how often a particular source of pain could be pinpointed and how often particular diagnostic blocks provided a positive yield...

BACKGROUND: Research into cervical spinal pain syndromes has indicated that the cervical facet joints can be a potent source of neck pain, headache, and referred pain into the upper extremities. There have been multiple diagnostic accuracy studies, most commonly utilizing diagnostic facet joint nerve blocks and an acute pain model, as Bogduk has proposed. Subsequently, Manchikanti has focused on the importance of the chronic pain model and longer lasting relief with diagnostic blocks...

OBJECTIVE: To determine the effectiveness of cervical medial branch thermal radiofrequency neurotomy in the treatment of neck pain or cervicogenic headache based on different selection criteria. DESIGN: Comprehensive systematic review. METHODS: A comprehensive literature search was conducted, and the authors screened and evaluated the studies. The Grades of Recommendation, Assessment, Development, and Evaluation system was used to assess all eligible studies...

OBJECTIVE: To determine the effectiveness of lumbar medial branch thermal radiofrequency neurotomy based on different selection criteria and procedural techniques. DESIGN: Comprehensive systematic review. METHODS: A comprehensive literature search was conducted, and all authors screened and evaluated the studies. The Grades of Recommendation, Assessment, Development, and Evaluation system was used to assess all eligible studies. OUTCOME MEASURES: The primary outcome measure assessed was the success rate of the procedure, defined by varying degrees of pain relief following neurotomy...

OBJECTIVES: To determine prevalence rates of hemorrhagic complications in patients who either ceased or continued anticoagulants during interventional pain procedures. METHODS: A total of 1,936 consecutive patients were prospectively monitored during a total of 12,723 injection procedures. The prevalence of hemorrhagic complications was tallied for a variety of procedures performed on patients who ceased or continued various anticoagulants. RESULTS: No hemorrhagic complications occurred in any patient who continued anticoagulants...

PURPOSE: Spinal column procedures require an accurate understanding of neural pathways relative to the anatomic structure. Since Bogduk's report in 1982, it has been known that the human lumbar posterior ramus of the spinal nerve (PRSN) comprise not two but three primary branches at least in some lumbar segments. The purpose of the current study was to examine the existence of the three primary branches in the thoracic and lumbar segments. METHODS: In this study, we investigated the anatomy of the human PRSN in the thoracic and lumbar segments...

Fracture liaison services (FLS) are an accepted approach to lowering rates of osteoporotic refractures. However, resource allocations to FLS are open to challenge, as most relevant cost analyses are based on anticipated, rather than observed, benefits. To support informed decision making, we have estimated the cost of operating an FLS, from the perspective of the Australian health system, with real life costs. On the basis of hospital records, we compared total costs of two cohorts of patients presenting with minimal trauma fractures (MTFs) at two hospital emergency departments (EDs) across a 6-month period (July to December 2010)...

The aim of this study was to determine the subdural haematoma recurrence rate in patients with symptomatic chronic subdural haematomas (CSDH) treated with either burr hole trephination (BHT) or minicraniotomy (MC) and to determine whether a statistically significant difference exists between the two techniques. A retrospective analysis of all consecutive patients with symptomatic CSDH treated with BHT or MC at the John Hunter Hospital Neurosurgery Department between July 2004 and July 2016 was performed. After inclusion/exclusion criteria were applied, 368 patients with 439 CSDHs were eligible...

Many conditions associated with chronic pain have no detectable morphological correlate. Consequently, the source of pain cannot be established by clinical examination or medical imaging. However, for some such conditions, the source of pain can be established using diagnostic blocks. The aim of this paper is to review the available evidence concerning the validity and utility of diagnostic blocks, and to identify areas where research is needed. Diagnostic blocks for cervical and lumbar zygapophysial joint pain have been extensively studied...
