Anatomical study of the medial branches of the lumbar dorsal rami: implications for image-guided intervention.
Fluoroscopic-guided radiofrequency ablation of the lumbar medial branches is commonly performed to manage chronic low back pain originating from the facet joints. A detailed understanding of the course of medial branches in relation to bony and soft tissue landmarks is paramount to optimizing lumbar denervation procedures, particularly parallel placement of the radiofrequency electrode. The objectives of this study were to investigate the relationship of medial branches to anatomical landmarks and discuss the implications for lumbar denervation. ⋯ A detailed understanding of the relationship of medial branches to anatomical landmarks is essential to optimizing needle placement for lumbar denervation procedures. The current study suggests that a parasagittal placement, with increased cranial-to-caudal angulation of the electrode, may improve parallel tip alignment with the targeted medial branch and represent a potential alternative to the traditional technique.

Lumbar spinal stenosis is a prevalent and disabling cause of low back and leg pain in older persons, affecting an estimated 103 million persons worldwide. Most are treated nonoperatively. Approximately 600 000 surgical procedures are performed in the US each year for lumbar spinal stenosis. ⋯ Lumbar spinal stenosis affects approximately 103 million people worldwide and 11% of older adults in the US. First-line therapy is activity modification, analgesia, and physical therapy. Long-term benefits from epidural steroid injections have not been established. Selected patients with continued pain and activity limitation may be candidates for decompressive surgery.

Association Between Family History of Surgically Treated Low Back Pain and Adolescent Low Back Pain.
Cross-sectional. ⋯ Our findings suggest that adolescents who report a family history of LBP have higher odds of frequent LBP irrespectively of a family history of back surgery.Level of evidence: 4.

The specific radiological feature of osteoporotic vertebral compression fractures (OVCFs) is bone marrow oedema (BME) on magnetic resonance imaging (MRI). However, the relationship between BME and back pain (BP) is unclear. We investigated the value of MRI in assessing BP and discussed the relevant mechanisms by tissue biopsy. ⋯ BME signals on MRI can accurately predict the degree of BP, and the main mechanisms are related to the stimulation of fibrous tissue.
