To explore the apparent diffusion coefficients of intervertebral discs in an asymptomatic pediatric cohort. ⋯ In our knowledge, our study provided the first diffusive properties of asymptomatic intervertebral discs in an adolescent cohort. ADC of NP was slightly higher than adults'. ADC evolutions of AAF were correlated with lordosis concavity which pointed out the role of compressive strain on fluid transport properties. This study could furnish information about segment homeostasis for exploration of pediatric spinal pathologies.

This study aimed to evaluate the progression of hip pathology and risk factors after ASD surgery. ⋯ This study identified the prevalence and risk factors for the progression of hip osteoarthritis after ASD surgery. Physicians need to pay attention to the hip joint pathology after ASD surgery.

Evidence has shown that lumbar vertebral endplate defects are clinically relevant and closely related to disc degeneration, but the relationship between endplate defects and bone mineral density (BMD) remains unclear. This study aimed to explore the association between endplate defects and BMD-related values in patients with lumbar degenerative disc disease (LDD). ⋯ The present study demonstrated that the occurrence of endplate defects was associated with greater lumbar BMD values in patients with LDD. This association varies for different defect subtypes and segments. The results indicated that endplate defects should be taken into consideration in osteoporosis treatment to alleviate disc degeneration.

To evaluate lumbosacral transitional vertebrae (LSTV) frequency in patients with low back pain and lumbar disc herniation (LDH) and to analyze correlations between LSTV presence and intervertebral disc degeneration. ⋯ A LDH is more common in the presence of a LSTV. Female sex is highly correlated with herniation. Three or more intervertebral disc levels are affected in the presence of an LSTV. Significantly higher degeneration incurs at the M1 and M2 intervertebral levels. Sacralization is a risk factors for a lumbar disc herniation.

The contents and subtypes of sacral cysts are sophisticated in many cases. We applied multiple dimensional magnetic resonance imaging (MRI) reconstruction to preoperatively clarify the specific subtype of sacral meningeal cysts. ⋯ MRI reconstruction based on the three-dimensional fast imaging employing steady-state acquisition T2 sequence precisely tracked the nerve roots of sacral cysts and guided the optimal strategy during surgery.
