Percutaneous vertebroplasty (PVP) is a common surgical method for osteoporotic vertebral compression fractures (OVCFs). The puncture method and location of the puncture needle can directly affect bone cement distribution in the vertebra. This retrospective study aimed to compare the clinical efficacy and safety of PVP using the cross-puncture and bilateral conventional puncture for the treatment of Genant grade 0-1 OVCFs. ⋯ Cross-puncture and bilateral conventional puncture were both effective methods for the treatment of Genant grade 0-1 OVCFs. However, the cross-puncture was more advantageous in terms of the bone cement leakage rate, amount of bone cement injected, bone cement distribution grade, and complications.

To determine the effect of obesity on clinical, radiographic, and surgical outcomes after lateral lumbar interbody fusion (LLIF) versus minimally invasive surgery (MIS) transforaminal lumbar interbody fusion (TLIF) and compare the effectiveness of LLIF versus MIS TLIF in treating obese patients. ⋯ Obesity was associated with poorer overall radiographic and surgical outcomes after MIS TLIF but not LLIF. In obese patients in our cohort, LLIF provided superior improvements in spinopelvic parameters and surgical characteristics. BMI should be considered when deciding between LLIF and MIS TLIF.

Craniopharyngioma is a benign, locally invasive tumor of the sellar-suprasellar region. Surgery can be curative but may require sacrifice of the pituitary stalk, which often leads to hypopituitarism. The risk/benefit of this maneuver is not well understood. ⋯ Our review indicates that stalk sacrifice is often required to achieve a durable cure in patients with craniopharyngiomas. While stalk sacrifice increases the risk of post-operative endocrinopathy, even if the stalk is preserved many patients will still become hypopituitary.

The causal relationship between mitochondrial DNA copy number (mtDNA-CN) and intervertebral disc degeneration (IVDD) remains unclear. The study aimed to investigate the causal relationship between mtDNA-CN and IVDD using Mendelian randomization analyses. ⋯ The study revealed that there is no causal relationship of mtDNA-CN on the risk of IVDD, nor does IVDD have a significant causal effect on mtDNA-CN. Although the study did not find a significant causal relationship, it provides valuable insights into the complex interplay between genetic factors and IVDD. Further research is needed to explore to better understand the underlying mechanisms of this condition.
