A case report. ⋯ TB should always be considered as a differential diagnosis of sacral lesions, and identifying multidrug resistance is equally important in its treatment. Lumbopelvic fixation is a safe and reliable option as it unloads the S1 segment by achieving fixation in the lumbosacral spine and iliac wings.

Case report. ⋯ We used DTI to diagnose a symptomatic lesion as an extra-foraminal lumbosacral lesion caused by compression of the L5 spinal nerve at the foramina. Because DTI can quantitatively measure damage to nerve fibers, it may be advantageous for the diagnosis of far-out syndrome.

Cross-sectional study using T1ρ magnetic resonance imaging (MRI) of lumbar spine in healthy young adults. ⋯ The data of this study showed a significant difference in IDD onset between sexes. T1ρ values correlate with Pfirrmann degenerative grade in young adults. However, the wide distribution of T1ρ values in healthy intervertebral disc highlights the low sensitivity of Pfirrmann grade to detect the early IDD changes. T1ρ can be potentially used as a clinical tool to identify early IDD and to create a reliable quantitative scale.

Intermittent Cyclic Mechanical Tension (ICMT) was applied to end plate chondrocytes by using an FX-4000T Flexercell Tension Plus unit (Flexcell International Corporation, Hillsborough, NC). Changes of end plate chondrocytes were observed after ICMT stimulation. ⋯ Our results directly showed that ICMT induced the calcification and downregulation of ankh gene expression of end plate chondrocytes, which may be caused by the endogenous TGF-β1.

A retrospective review. ⋯ The use of wider intervertebral cages leads to a significantly lower rate of subsidence, but a longer cage does not necessarily offer a similar advantage. Wide cages are protective against subsidence, and the widest cages should be used whenever feasible for interbody fusion in the lumbar spine to protect indirect compression and promote arthrodesis.
