Lumbar facet joint subchondral bone density in low back pain and asymptomatic subjects

AbstractObjectiveTo report in vivo measurements of lumbar facet joint subchondral bone mineral density used in the description of facet joint loading patterns and to interrogate if low back pain is associated with changes in subchondral bone mineral density.Materials and methodsIn vivo measurements of lumbar facet joint subchondral bone mineral density (L1/2 to L5/S1) in Hounsfield units were performed on 89 volunteers (56 controls and 33 with low back pain) by computed tomography osteoabsorptiometry at subchondral regions between 1.5  mm and 2.5 mm below the joint surface. The facet surface was divided into five topographic zones: cranial, lateral, caudal, medial, and central.ResultsWe analyzed 1780 facet joint surfaces. Facets were denser (p

Conclusions: Clinical symptoms and spinal fusion efficiency were not significantly different between CBT and PS except for postoperative improvement in low back pain. The treatment effect on postoperative low back pain was smaller for CBT than for PS. PMID: 32213798 [PubMed - as supplied by publisher]

C, Hartmann S Abstract Pedicle fractures are rare and usually associated with repetitive stress, high-speed trauma, osteoporosis, unilateral spondylolysis, or instrumentation surgery. A review of the current literature on bilateral pedicle fractures of the lumbar spine revealed only a few cases listed as a complication of instrumentation or excessive decompression surgery. The authors present the clinical case of a 49-year-old man with exacerbating low-back pain and intermittent L5 radicular pain. The known comorbidities were rather remarkable for systemic lupus erythematosus and osteopenia. Radiological investiga...

Low back pain is one of most common musculoskeletal disorders around the world. One major problem clinicians face is the lack of objective assessment modalities. Computed tomography and magnetic resonance imaging are commonly utilized but are unable to clearly distinguish patients with low back pain from healthy patients with respect to abnormalities. The reason may be the anisotropic nature of muscles, which is altered in function, and the scans provide only structural assessment. In view of this, ultrasound may be helpful in understanding the disease as it is performed in real-time and comprises different modes that meas...

This study aimed to compare the biomechanical properties of the lumbar extensor myofascia in elderly patients with chronic low back pain and healthy people when resting and to analyze the relationship between the Japanese Orthopedic Association (JOA) score, visual analog scale (VAS) score, Cobb angle, and disease course and the biomechanical characteristics of the lumbar extensor myofascia. This case-control study included 40 elderly patients with chronic low back pain and 40 healthy volunteers. MyotonPRO was used to measure the biomechanical properties of the bilateral lumbar extensor myofascia (at L3/L4 level) in all par...

Magnetic resonance imaging of the spine showed high signal intensity, diagnosed as a cystic lesion in the epidural and bilateral intestinal psoas muscle. A computed tomography-guided needle biopsy and histological examination revealed bacteria from the family Mycobacteriaceae, and Mycobacterium bovis was identified using multiplex polymerase chain reac...

ConclusionThis is the first ever study reporting the changes in cerebral metabolic activity and multi ‐frame static brain18F FDG PET imaging after L2 DRG stimulation for discogenic low back pain. Predominantly an increased metabolic activity in nociceptive brain matrices are seen with an increased in F18F FDG uptake following L2 DRG stimulation.

We present a case report of an adult woman with AKL-positive ALCL, diagnosed by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA).A 59-year-old women with no history of breast implants, was admitted for a four-month low back pain. Initially, the patient was treated for a spondyloarthropathy, but due to persistence of the symptoms, a lumbosacral MRI was performed, showing changes in morphology and signal intensity in the vertebral body of L3, along with edema and a paravertebral collection that affected the left psoas muscle, suggesting granulomatous spondylodiscitis. Chest CT-scan showed mild left ...

Conclusion Based on preoperative Kambin's triangular working zone measurements from 3D CT/MR fusion images, F + outside-in should be selected when the working zone is smaller than the cannula diameter. This method successfully avoided POD in our study. Preoperative Kambin's triangular working zone measurements from 3D CT/MR fusion imaging can enhance patient safety during TELD.
