BACKGROUND: This study examined short- and long-term improvements in motor performance, quantified using wearable sensors, in response to facet spine injection in degenerative facet osteoarthropathy patients. METHODS: Adults with confirmed degenerative facet osteoarthropathy were recruited and were treated with medial or intermediate branch block injection. Self-report pain, health condition, and disability (Oswestry), as well as objective motor performance measures (gait, balance, and timed-up-and-go) were obtained in five sessions: pre-surgery (baseline), immediately after the injection, one-month, three-month, and 12-month follow-ups...

BACKGROUND: Headache (HA) is a significant cause of morbidity globally. Despite many available treatment options, HAs that are refractory to conservative management can be challenging to treat. Third occipital nerve (TON) and greater occipital nerve (GON) irritation are potential etiologic agents of primary and cervicogenic HAs that can be targeted using minimally invasive treatment options such as nerve blocks or radiofrequency ablation. However, a substantial number of patients that undergo radiofrequency ablation do not experience pain relief despite a positive diagnostic medial branch block (MBB)...

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-procedural oral analgesic use in patients receiving continuous thermal radiofrequency ablation versus patients receiving pulsed dose radiofrequency immediately followed by continuous thermal radiofrequency ablation for zygopophaseal joint disease...

Ultrasound-guided cervical medial branch block (CMBB) is commonly performed to diagnose and treat head, neck, and shoulder pain. However, its use at the C7 level has been shown to be less accurate than at other levels, which may increase the chance of injury owing to the imprecision of needle site provided by the ultrasound guide. We report the first case of iatrogenic spinal cord injury from an ultrasound-guided C7 CMBB. The patient, upon receiving this procedure, had fainted shortly after experiencing an electrical sensation that ran from the neck to the toe...

OBJECTIVE: To compare the visibility and procedural parameters between a standard spinal needle and a new laser-etched needle (LEN) in real-time ultrasonography guided lumbar medial branch access in a phantom of the lumbosacral spine. METHODS: We conducted a prospective single-blinded observational study at a rehabilitation medicine center. A new model of LEN was manufactured with a standard 22-gauge spinal needle and a laser etching machine. Thirty-two inexperienced polyclinic medical students performed ultrasonography-guided lumbar medial branch access using both a standard spinal needle and a LEN with scanning protocol...

No major complications have been associated with the ultrasound-guided continuous adductor canal block (cACB). We present a case of iatrogenic pseudoaneurysm in a branch of the superficial femoral artery in a 44-year-old patient after a cACB for knee surgery. Both anesthesia and surgery were completed uneventfully. The postoperative day 3 examination showed a complete quadricep impairment and a large hematoma in a medial-anterior part of the thigh, and laboratory tests reported hemoglobin = 7.2 g dL. The computed tomography scan revealed the pseudoaneurysm (16 × 16 × 18 mm) that was successfully embolized after selective catheterization...

PURPOSE OF REVIEW: This review offers a critical examination of the biomechanical model that posits the posterior elements as a substantial contributor to pain in vertebral fracture. Further, the review assesses the treatment of posterior-element-associated pain in the setting of vertebral compression fracture in relation to vertebral augmentation. RECENT FINDINGS: In 2015, the only prospective randomized trial comparing percutaneous vertebroplasty with facet blockade was published in which authors found that percutaneous vertebroplasty produced better pain relief and function based on Oswestry Disability Index, Roland Morris Disability Questionnaire, and visual analog scale in the short term (≤1 week)...

Low back pain (LBP) is a major medical and economical problem, because of its high incidence. Indeed, 70-85% of adult people will suffer from this kind of pain once in their life. We will focus in this article on chronic LBP, which represent an annual prevalence of 30% and more specifically on mechanical pain, with our without radiation into the legs. In case of failure of traditional analgesia combining drugs and physical therapies, we can propose interventional pain relief. This involves a series of diagnostic blocks (medial branch blocks), followed by the treatment (radiofrequency ablation)...

As the population ages, more patients are developing degenerative changes of the spine and associated pain. Although interventional procedures for axial and radicular spine pain have been available for decades, common imaging modalities have relied on ionizing radiation for guidance. Over the past decade, ultrasound has become increasingly popular to image both peripheral musculoskeletal and axial structures. This article reviews the use of ultrasound in the guidance of spine procedures, including cervical and lumbar facet injections and medial branch blocks, third occipital nerve blocks, thoracic facet and costotransverse joint injections, sacroiliac joint injections, and caudal and interlaminar epidural injections...

BACKGROUND: Guidelines have been published that recommend discontinuing anticoagulants in patients undergoing interventional pain procedures. The safety and effectiveness of these guidelines have not been tested. OBJECTIVES: The present study was performed to determine if continuing or discontinuing anticoagulants for pain procedures is associated with a detectable risk of complications. METHODS: An observational study was conducted in a private practice in which some partners continued anticoagulants while other partners routinely discontinued anticoagulants...

UNLABELLED: In lumbar pain patients an aetiopathogenic diagnosis leads to a better management. When there are alarm signs, they should be classified on an anatomical basis through anamnesis and physical examination. A significant group is of facet origin (lumbar facet syndrome [LFS]), but the precise clinical diagnosis remains cumbersome and time-consuming. In clinical practice it is observed that patients with an advanced degenerative disease do not perform extension or rotation of their lumbar spine when prompted to extend it, but rather knee flexion, making the manoeuvre meaningless...

From March 2012 to February 2013, 37 patients experiencing plantar heel pain for ≥6 months despite treatment with physical therapy and other conservative treatment modalities were followed up. If neurogenic heel pain originating from the first branch of the lateral plantar nerve was present, with or without the medial calcaneal nerve, diagnostic nerve blocks to these nerves were performed for confirmation. If the pain was determined to be of neurogenic origin, radiofrequency neural ablation (RFNA) was applied to the corresponding sensory nerve endings...

OBJECTIVE: This study explores the prevalence of facet joint pain in chronic Whiplash Associated Disorder (WAD). DESIGN: Forty-seven patients with chronic WAD were scheduled for medial branch blocks of the cervical spine. METHODS: The patient's localization of the pain together with established pain maps guided to the first level of zygapophyseal joint to be tested. The joint was anesthetized by injecting bupivacaine (0.5 ml; 5 mg/ml) to the medial branches of the cervical dorsal rami above and below the joint...

We report 2 cases of successful treatment of neck and back pain with bipolar radiofrequency ablation (RFA) of the cervical and lumbar facet joints in patients with an automatic implantable cardioverter defibrillator (AICD).Two patients with complex cardiac histories and AICD devices were treated with bipolar RFA of the facet joints. One presented with axial neck pain and the other with axial back pain. The histories and physical examinations were consistent with facetogenic pain. Diagnostic medial branch block resulted in more than 70% pain relief lasting for several days, allowing patients to perform routine daily activities without significant pain...

BACKGROUND: Low back pain is a disabling and common condition, whose etiology often remains unknown. A suggested, however rarely considered, cause is neuropathy of the medial branch of the superior cluneal nerves (mSCN)-either at the level of the originating roots or at the point where it crosses the iliac crest, where it is ensheathed by an osseo-ligamentous tunnel. Diagnosis and treatment have, to date, been restricted to clinical assessment and blind infiltration with local anesthetics...

BACKGROUND: Facet joint pain is a common cause of low back pain. There are no physical exam findings that provide a reliable diagnosis. Diagnosis is made by medial branch block injections (MBB). Once the source of pain has been determined, radiofrequency neurotomy (RFN) can be performed. Previous studies have shown that RFN reduces level of pain and improves function. No study has tried to correlate MBB results with outcomes after RFN. OBJECTIVES: (1) Estimate percentage decrease in pain, decrease in analgesic use, and increase in activity tolerance after facet joint radiofrequency neurotomy (2) Determine correlation between percentage pain relief or duration of pain relief after MBB and RFN outcomes...

BACKGROUND AND OBJECTIVES: Intravascular (IV) injection of local anesthetics is a potential cause of false-negative results after lumbar medial branch nerve blockade (L-MBB) performed to diagnose facetogenic back pain. The aim of the present study was to identify the relationship between the needle type and the incidence of IV injection in patients undergoing L-MBB using fluoroscopy with digital subtraction imaging (DSI). METHODS: In this prospective randomized study, we compared the incidence of IV uptake of contrast medium using the Quincke needle and Whitacre needle under real-time DSI during L-MBB...

BACKGROUND: Low back pain is an extremely common and often chronic condition. In some cases, this is due to an irritative arthropathy of zygapophyseal joint involving the medial branch of the dorsal ramus of the spinal nerve. Percutaneous radiofrequency thermocoagulation appears to be the most effective treatment to date, among a range of different treatments. In this paper, the technique is described as performed at out institution. METHODS: In supine position and under fluoroscopic control, a radiofrequency electrode is inserted into different articular zygapophyseal complexes to thermocoagulate ramifications of the medial branch of the dorsal primary ramus of the spinal nerve...

Fluoroscopy guidance is useful to confirm anatomical landmark and needle location for spine intervention; however, it can lead to radiation exposure in patients, physicians, and medical staff. Physicians who used fluoroscopy should be cognizant of radiation exposure and intend to minimize radiation dose. We retrospectively reviewed three lumbar spine intervention procedures (nerve root block, medial branch block, and facet joint block) at our institution between June and December, 2014. We performed 268 procedures on 220 patients and found significant difference in radiation dose between two groups classified by performing physicians...
