In chronic low back pain (CLBP) patients, study of altered brain metabolites in the anterior cingulate cortex (ACC) using magnetic resonance spectroscopy (MRS) could reveal the detailed pathology of CLBP and depression. The aim was to detect the central difference between CLBP and controls by means of measuring the metabolites in the ACC, and to analyze the correlations between depression and metabolites in ACC. ⋯ Lower NAA levels and higher Glx/creatine and Glx/myoinositol ratios in the ACC of CLBP participants compared with controls were revealed. The result suggests the hypothesis that excessive Glx leads to neuronal dysfunction and/or death, which was reflected as a low NAA level in the ACC of individuals with CLBP. Measurement of these metabolites using MRS potentially helps evaluate CLBP patients' condition and psychological status objectively.

Case ReportsDifferential Diagnosis of a Pathological Spine Fracture.
A 71-year-old woman with a 10-month history of atraumatic low back pain was referred to physical therapy after an insidious exacerbation of symptoms. Red flags raised suspicions for spinal compression fracture, necessitating the physical therapist to contact her physician and recommend imaging. ⋯ Following bone scintigraphy and an ultrasound-guided biopsy of a liver lesion, she was diagnosed with metastatic breast cancer. J Orthop Sports Phys Ther 2018;48(7):595. doi:10.2519/jospt.2018.7768.

Chiropractic care is popular for low back pain, but may increase the risk for acute lumbar disc herniation (LDH). Low back pain is a common early (prodromal) symptom of LDH and commonly precedes LDH diagnosis. Our objective was to investigate the association between chiropractic care and acute LDH with early surgical intervention, and contrast this with the association between primary care physician (PCP) care and acute LDH with early surgery. ⋯ Both chiropractic and primary medical care were associated with an increased risk for acute LDH requiring ED visit and early surgery. Our analysis suggests that patients with prodromal back pain from a developing disc herniation likely seek healthcare from both chiropractors and PCPs before full clinical expression of acute LDH. We found no evidence of excess risk for acute LDH with early surgery associated with chiropractic compared with primary medical care.

The etiology of low back pain (LBP) is complicated and the diagnosis can be difficult. Superior cluneal nerve entrapment neuropathy (SCN-EN) is a known cause of LBP, although the middle cluneal nerve (MCN) can be implicated in the elicitation of LBP. ⋯ The MCN consists of sensory branches from the dorsal rami of S1-S4. It sandwiches the sacral ligament between the posterior superior and inferior iliac spine as it courses over the iliac crest. Its entrapment at this hard orifice can lead to severe LBP with leg symptoms. An MCN block effect is diagnostically useful. Less invasive MCN neurolysis under local anesthesia is effective in patients who fail to respond to observation therapy.

Lumbar paraspinal muscle morphology has recently been evaluated in several studies with conflicting results. Several studies have performed single-slice evaluations of paraspinal muscle morphology, whereas other studies have done a multi-level assessment; this methodological difference might explain the observed different results. Our study evaluated if a single-slice axial measurement is representative of the entire lumbar musculature. ⋯ No single-level FSF or CSA is representative of the whole lumbar spine. A standardized multi-level evaluation of the paraspinal musculature should be used in future research.
