Radiofrequency ablation joint

John Tran, Philip W H Peng, Karen Lam, Ehtesham Baig, Anne M R Agur, Michael Gofeld
BACKGROUND AND OBJECTIVES: The knee joint is the most common site of osteoarthritis. While joint replacement is considered an ultimate solution, radiofrequency denervation may be contemplated in some cases. Radiofrequency ablation requires precise localization of the articular branches innervating the joint capsule. The objective of this cadaveric study was to determine the source, course, relationships, and frequency of articular branches innervating the anterior knee joint capsule. METHODS: Fifteen knees were meticulously dissected...

AIMS: Paroxysmal atrial fibrillation (PAF) commonly recurs after radiofrequency catheter ablation (RFCA). This study aimed to assess left atrial appendage (LAA) volume and function by transesophageal echocardiography (TEE) and to explore its value in predicting PAF recurrence after RFCA. METHODS: Eighty patients with PAF were recruited. The left atrial (LA) and LAA volume and function were measured by transthoracic echocardiography (TTE) and TEE before ablation...

BACKGROUND: Patients who undergo radiofrequency ablation of atrial fibrillation with a light conscious sedation often feel pain during the procedure which can be difficult to relieve with pharmacological pain treatment alone. In a quasi-experimental study, it was found that visualization together with usual pain medication reduced the amount of analgesics used. In addition, patients spontaneously expressed pain significantly fewer times outside the scheduled measurements. No difference was found in the perception of pain intensity or anxiety and procedure length in the study...

Background: Current sacroiliac joint (SIJ) cooled radiofrequency (RF) is based on fluoroscopic anatomy of lateral branches (LBs) in three specimens. Recent studies confirm significant variation in LB positions. Objectives: To determine if common fluoroscopic needle placements for cooled SIJ RF are adequate to lesion all S1-3 LBs. If not, would different targets improve lesion accuracy? Methods: The LBs of 20 cadavers were dissected bilaterally (40 SIJs), and 26 G radiopaque wires were sutured to the LBs...

Sacroiliac joint (SIJ) pain is an important cause of lower back problems. Multiple SIJ injection techniques have been proposed over the years to help in the diagnosis and treatment of this condition. However, the SIJ innervation is complex and variable, and truly intra-articular injections are sometimes difficult to obtain. Different sacroiliac joint injections have shown to provide pain relief in patients suffering this ailment. Various techniques for intraarticular injections, sacral branch blocks and radiofrequency ablation, both fluoroscopy guided and ultrasound guided are discussed in this paper...

BACKGROUND AND OBJECTIVES: Chronic hip pain from osteoarthritis and other degenerative conditions is a common problem. A few publications have recently reported analgesic success of radiofrequency (RF) procedures on nerves innervating the hip, but interpretation is hampered by lack of clarity regarding indications, clinical protocols, anatomic targets, and longevity of benefit from RF procedures. METHODS: We reviewed the following medical literature databases for publications on RF procedures on the hip joint for chronic pain: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Google Scholar through February 28, 2017...

Radiofrequency facet ablation (RFA) has been performed using the same technique for over 50 years. Except for variations in electrode size, tip shape, and change in radiofrequency (RF) stimulation parameters, using standard, pulsed, and cooled RF wavelengths, the target points have remained absolutely unchanged from the original work describing RFA for lumbar pain control. Degenerative changes in the facet joint and capsule are the primary location for the majority of lumbar segmental pathology and pain. Multiple studies show that the degenerated facet joint is richly innervated as a result of the inflammatory overgrowth of the synovium...

Sacroiliac joint (SIJ) dysfunction is a common cause of low back pain in the athlete, especially in sports with repetitive, asymmetric loading. Complex anatomy and broad pain referral pattern make diagnosis difficult. Identifying three or more positive physical examination maneuvers for the SIJ improves examination sensitivity and specificity. Imaging is rarely helpful in establishing the diagnosis but is often used to rule out other pathology. Conservative management with activity modification, medication, physical therapy, manipulation and bracing is first line treatment...

INTRODUCTION: We report a case of a lost metal platelet from a radiofrequency ablation probe (VAPR VUE Radiofrequency System, Cool Pulse 90, DePuy, Synthes, Switzerland) in the shoulder joint during elective arthroscopic cuff repair. To the best of our knowledge, this kind of an incident during elective arthroscopy has not been described in the literature so far. In addition, we present an algorithm on how to deal with such an incident. CASE REPORT: A 69-year-old woman underwent an arthroscopic subacromial decompression and rotator cuff repair for a torn supraspinatus tendon...

Osteoid osteoma has been reported infrequently around the elbow joint, and is usually treated with radiofrequency ablation or open excision. Elbow arthroscopy is useful for excision of accessible lesions, and the accompanying elbow stiffness can be treated concurrently. This report describes an arthroscopic excision of an osteoid osteoma located in the juxta-articular distal humeral bone. An initial adhesiolysis and capsulectomy is performed to gain access to the region above the capitellar articular margin...

BACKGROUND: Low back pain is the leading cause of years lost to disability with approximately 15%-25% of the chronic back pain population suffering from lumbar facet arthropathy. No large-scale study has sought to systematically identify inciting events for lumbar facet arthropathy. The aim of this study is to quantify the proportion of individuals with lumbar facetogenic pain who report a specific precipitating event(s) and to determine if there is a correlation between these events and treatment outcome...

Lumbar facet cysts are frequently found in patients with facet degeneration and segmental instability. When the facet cyst is localized in the neural foramina and lateral recess or becomes large, it can cause radiculopathy or neurogenic claudication. These symptomatic cysts are typically treated interventionally with drainage and a corticosteroid injection or attempts via overinflation to rupture the cyst; however, these procedures have a significant recurrence rate (up to 50%) and often need to be repeated or lead to lumbar surgery if unsuccessful...

Lower back pain (LBP) is a global public health issue and is associated with substantial financial costs and loss of quality of life. Over the years, different literature has provided different statistics regarding the causes of the back pain. The following statistic is the closest estimation regarding our patient population. The sacroiliac (SI) joint pain is responsible for LBP in 18%-30% of individuals with LBP. Quadrapolar™ radiofrequency ablation, which involves ablation of the nerves of the SI joint using heat, is a commonly used treatment for SI joint pain...

A 12-year-old girl presented with a history of cervical mass, and one week of throat discomfort and dyspnea. Five years ago, the patient was diagnosed as Hashimoto's thyroiditis and hyperthyroidism; she received antithyroid drug treatment, but the result was not satisfactory. B-ultrasonic showed that the size of thyroid gland was 8.1 cm×3.2 cm in the left and 8.2 cm×4.8 cm in the right. After iodine 131 combined with radiofrequency ablation (RFA) treatment, throat discomfort and recumbent breathing difficulties disappeared, and B-ultrasonic showed that the size of thyroid reduced to 2...

INTRODUCTION: A small subset of patients who underwent successful vertebral compression fracture (VCF) augmentation procedures may develop subsequent pain requiring spinal injections. In a retrospective analysis, we determined whether the pain was related to the original fracture site or to another area within the lumbar or thoracic spine. The pain occurred either at the same/adjacent level and/or non-adjacent level as the VCF. Interventional treatments primarily targeted the facet joints, specifically in the form of facet joint blocks and/or radiofrequency ablation to the medial branches...

Introduction: Tumors invading the sacrum and/or ilium often represent incurable metastatic disease, and treatment is targeted toward palliation of symptoms and control of pain. As systemic opioid therapy is frequently inadequate and limited by side effects, a variety of interventional techniques are available to better optimize analgesia. Using six patients as a paradigm for interventional approaches to pain relief, we present a therapeutic algorithm for treating sacroiliac tumor-related pain in the oncologic population...
