Current trends in intraoperative neurophysiological monitoring among Asia-Pacific countries: an Asia-Pacific Spine Society survey.

Study Design: A prospective web-based survey.

Purpose: Although intraoperative neurophysiological monitoring (IONM) is critical in spine surgery, its usage is largely based on the surgeon's discretion, and studies on its usage trends in Asia-Pacific countries are lacking. This study aimed to examine current trends in IONM usage in Asia-Pacific countries.

Quality of life in surgical treatment of metastatic spine disease.

Study Design: Overall quality of life after surgical management of metastatic disease of the spine was prospectively assessed using a validated global health status quality-of-life instrument-the Edmonton Symptom Assessment Scale.

Objectives: To prospectively evaluate the efficacy of surgery in patients with metastatic spinal disease with respect to quality of life.

Summary Of Background Data: Management of spinal metastases is palliative and is aimed at improving quality of life at an acceptable risk.
