Objective. Determine outcomes of cooled radiofrequency ablation (C-RFA) the genicular nerves for treatment chronic knee pain due to osteoarthritis (OA).
The past two decades have witnessed a surge in the use of cervical spine joint procedures including injections, nerve blocks and radiofrequency ablation to treat chronic neck pain, yet many aspects remain controversial.
Background. Transforaminal epidural steroid injections (TFESI) have demonstrated efficacy and effectiveness in treatment of radicular pain. Despite little evidence efficacy/effectiveness, interlaminar (ILESI) are advocated by some as primary therapy for pain due to purported greater safety.
Cross-sectional cohort study of chronic low back pain (CLBP) patients and matched controls.To explore the interplay between vertebral endplate damage adjacent paraspinal muscle (PSM) quality, to test their association in a with CLBP controls.Nonspecific is challenging diagnose, part, due uncertainty regarding source pain. Delineating interactions among potential mechanisms may enhance diagnosis treatment customization.We collected advanced MRI imaging on 52 adult subjects, including 38 14...
The aim of this study was to investigate the psychometric properties Oswestry Disability Index (ODI) in a large cross-sectional cohort individuals with chronic low back pain by defining its internal consistency, construct structure and validity, ability differentiate between different degrees functional limitation. A total 837 consecutive outpatient patients were studied. consistency ODI assessed Cronbach's α, exploratory factor analysis, validity confirmatory discrimination determined item...
Background and objectives No previous study has assessed the outcomes of cooled radiofrequency ablation (C-RFA) medial branch nerves (MBN) for treatment lumbar facet joint pain nor compared its effectiveness with traditional RFA (T-RFA). This evaluated 6-month pain, function, psychometrics, medication usage in patients who underwent MBN C-RFA versus T-RFA Z-joint pain. Methods In this blinded, prospective trial, positive diagnostic blocks (>75% relief) were randomized to or T-RFA. The...
Radiofrequency ablation (RFA) of the medial branch nerves for facet-mediated low back pain demonstrates clinical benefit 6-12 months and possibly up to 2 years. This study investigated function, pain, medication use outcomes RFA lumbar facet syndrome in a cohort with long-term follow-up.Individuals evaluated tertiary academic practice between January, 2007-December, 2013, 18-60 years age, radiologic diagnosis syndrome, who underwent ≥1set diagnostic blocks resultant >75% relief subsequent...
Baclofen commonly is used to manage spasticity caused by central nervous system lesions or dysfunction. Although both intrathecal and oral delivery routes are possible, no study has directly compared clinical outcomes associated with these 2 of treatment.To compare levels, pain, sleep, fatigue, quality life between individuals receiving treatment versus baclofen.Cross-sectional matched cohort survey study.Urban academic rehabilitation outpatient clinics.Adult patients spasticity, treated...
Setting. Interventional procedures directed toward sources of pain in the axial and appendicular musculoskeletal system are performed with increasing frequency. Despite presence evidence-based guidelines for such procedures, there wide variations practice. Case reports serious complications as spinal cord infarction or infection from spine injections lack appropriate context create a misleading view risks appropriately interventional procedures. Objective. To evaluate adverse event rate at...
Fluoroscopically guided cooled genicular nerve radiofrequency ablation (RFA) is an increasingly performed procedure for chronic, refractory knee pain due to osteoarthritis. Traditionally, partial sensory denervation has been accomplished through of the superomedial, superolateral, and inferomedial nerves. However, recent cadaveric studies have demonstrated additional nerves significant anatomic variation that impact current protocols.We describe updated protocol accounts varied location...
Abstract Objectives Although the effectiveness of lumbar medial branch radiofrequency ablation (RFA) for treatment zygapophyseal joint (z-joint)–mediated low back pain has been characterized, few studies have described outcomes in patients selected using a guideline-concordant paradigm ≥80% relief with dual comparative blocks (MBBs). We investigated long-term according to this paradigm. Design Cross-sectional cohort study. Methods The medical records 111 consecutive were reviewed; 85 met...
This study compares two pain intensity metrics, calculated percentage reduction (CPPR) and patient-reported (PRPPR), in patients undergoing medial branch nerve blocks (MBB) to determine their comparability agreement. A retrospective review of prospectively enrolled consecutive MBB with axial spine from multiple centers. Data was collected via self-report diaries analyzed using linear regression models, concordance correlation coefficients (CCC), Bland-Altman plots. One hundred fifty yielded...
