OBJECTIVES: Lumbar facet joint syndrome (LFJS) is the cause of lower back pain in 15-54% of the patients. Clinical studies of cryotherapy for LFJS have reported promising outcomes. However, few studies have focused on the technical aspects of cryoneurolysis for LFJS. The aim of the study was to determine the size and shape of cryolesions in vitro and to determine how they are affected by the duration of freezing, size of the cryoprobe and distance and angulation to an osseous boundary layer...

OBJECTIVES: Chronic pain and long-term opioid use may lead to a persistent deficit in hedonic capacity, characterized by increased sensitivity to aversive states and insensitivity to natural rewards. Dispositional mindfulness has been linked with improved emotion regulation and pain coping. The aim of the current study was to examine associations between dispositional mindfulness, hedonic capacity, and pain-related interference in an opioid-using chronic pain sample. METHODS: Data were obtained from a sample of 115 chronic pain patients on long-term opioid therapy (68% females, M age=48...

Chronic joint pain is a widespread problem that frequently occurs with aging and trauma. Pain occurs most often in synovial joints, the body's load bearing joints. The mechanical and molecular mechanisms contributing to synovial joint pain are reviewed using two examples, the cervical spinal facet joints and temporomandibular joint. Although much work has focused on the macroscale mechanics of joints in health and disease, the combined influence of tissue mechanics, molecular processes, and nociception in joint pain has only recently become a focus...

Cervical arthroplasty is being recognized as an emerging alternative to anterior cervical fusion with comparable or superior outcomes. The authors describe the surgical nuances of 2-level cervical arthroplasty in a case of 2-level degenerative disease. In this surgical technique, conventional vertebral body distraction has been avoided to prevent facet distraction, which can be a cause of persistent postoperative neck pain. Good motion preservation was observed at the 1-year follow-up examination. The video can be found here: https://youtu...

SETTING: Interventional procedures directed toward sources of pain in the axial and appendicular musculoskeletal system are performed with increasing frequency. Despite the presence of evidence-based guidelines for such procedures, there are wide variations in practice. Case reports of serious complications such as spinal cord infarction or infection from spine injections lack appropriate context and create a misleading view of the risks of appropriately performed interventional pain procedures...

PURPOSE: Intervertebral disc degeneration is thought to contribute to low back pain. However, the pathophysiological mechanisms remain controversial. In a previous study, we developed an animal model that showed delayed gait disturbance after lumbar facetectomy in the rat. We believe that this gait disturbance was caused by low back pain, although the mechanisms of this gait abnormality remain unknown. The purpose of this study was to evaluate structural changes of the lumbar spine after facetectomy in the rat utilizing three-dimensional micro-computed tomography (3DμCT) compared to histology...

BACKGROUND: Septic arthritis of the atlantoaxial facet joint is extremely rare. Contiguous spread to the median atlantoaxial joints with subsequent dens erosion can lead to atlantoaxial instability. Misleading normal inflammatory markers can result in delayed diagnosis and catastrophic consequences. CASE DESCRIPTION: A 56-year-old man presented with right-sided neck pain that had lasted for 2 days. He did not have fever or chills, and his serum C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were normal...

OBJECTIVE: Hip morphology plays a significant role in the incidence and progression of hip osteoarthritis (OA). We hypothesized that hip shape would also associate with other key factors and tested this in a longitudinal community-based cohort combining radiographic, MRI, DXA, and clinical data. METHODS: Baseline dual-energy X-ray absorptiometry (DXA) images of the left hip of 831 subjects from the Tasmanian Older Adult Cohort (TASOAC) were analyzed using an 85-point statistical shape model...

: Poorly controlled pain is a global public health issue. The personal, familial and societal costs are immeasurable. Only a minority of European patients have access to a comprehensive specialist pain clinic. More commonly the responsibility for chronic pain management and initiating opioid therapy rests with the primary care physician and other non-specialist opioid prescribers. There is much confusing and conflicting information available to non-specialist prescribers regarding opioid therapy and a great deal of unjustified fear is generated...

Survival rate for childhood cancer has increased in recent years, reaching as high as 70% in developed countries compared with 54% for all cancers diagnosed in the 1980s. In the remaining 30%, progression or metastatic disease leads to death and in this framework palliative care has an outstanding role though not well settled in all its facets. In this landscape, surgery has a supportive actor role integrated with other welfare aspects from which are not severable. The definition of surgical palliation has moved from the ancient definition of noncurative surgery to a group of practices performed not to cure but to alleviate an organ dysfunction offering the best quality of life possible in all the aspects of life (pain, dysfunctions, caregivers, psychosocial, etc...

Advances in imaging and the development of injection techniques have enabled spinal intervention to become an important tool in managing chronic spinal pain. Epidural steroid injection (ESI) is one of the most widely used spinal interventions; it directly delivers drugs into the epidural space to relieve pain originating from degenerative spine disorders-central canal stenoses and neural foraminal stenoses-or disk herniations. Knowledge of the normal anatomy of the epidural space is essential to perform an effective and safe ESI and to recognize possible complications...
