Percutaneous kyphoplasty (PKP) is a minimally invasive procedure for the treatment of osteoporotic vertebral compression fractures (OVCFs). It is generally considered that there is little blood loss during the surgery. However, a significant perioperative hidden blood loss (HBL) is neglected. This study was to examine the amount of HBL and determine the influential factors during PKP. ⋯ HBL cannot be ignored in perioperative period, especially for poor physical condition and multiple fractures patients. Having a correct understanding of HBL can help improve clinical assessment capabilities, ensuring patients' safety.

To evaluate postoperative recurrence, survival and metastasis results and related factors of sacral chordoma. ⋯ Sacral chordoma tended to occur in elderly male patients and locate below sacral 3 level. The recurrence rate was high, especially for tumor above sacral 3 level. Wide surgical margin is very important for good local control. The patients with metastasis had poor prognosis.
