Bone cement distribution patterns in percutaneous kyphoplasty (PKP) is the key factor in keeping the vertebral stabilization and curative effect. However, the same cement volume can result in different bone cement distribution patterns and can thereby lead to different clinical outcomes. Therefore we investigated associations between cement distribution patterns and the occurrence rates of recompression in cemented vertebrae after PKP for patients with osteoporotic vertebral compression fractures (OVCFs). ⋯ Percutaneous kyphoplasty, osteoporotic vertebral compression fracture, bone cement distribution patterns.

Intraspinal cement leakage is a catastrophic complication of percutaneous vertebroplasty (PVP). Percutaneous endoscopic spinal surgery (PESS) for intraspinal cement leakage has rarely been reported. ⋯ Endoscopes, cement leakage, minimally invasive surgery, percutaneous vertebroplasty.

Observational Study
Pressure-Induced Referred Pain as a Biomarker of Pain Sensitivity in Fibromyalgia.
Fibromyalgia (FM) syndrome is characterized by widespread pain, fatigue, and generalized increased pain sensitivity. Appropriate and simple pain models are methods employed to assess pain mechanisms that can potentially lead to improved treatments. Pressure pain thresholds (PPTs) or mapping the referred pain area produced by pressure stimulation at suprathreshold intensities are used to assess pain mechanisms. The optimal suprathreshold stimulation intensity to elicit referred pain with minimal discomfort for patients with FM has yet to be determined. ⋯ Referred pain, pain sensitivity, fibromyalgia, central sensitization, suprathreshold, pressure pain threshold, biomarker, facilitated pain mechanisms.
