Primary malignant bone tumors and solitary metastases of the thoracolumbar spine: results by management with total en bloc spondylectomy.

Primary malignant spinal tumors and solitary vertebral metastases of selected tumor entities in the thoracolumbar spine are indications for total en bloc spondylectomy (TES). This study aimed to describe our oncological and surgical management and to analyze the treatment results by management with TES for extra- and intracompartmental solitary spinal metastases and primary malignant vertebral bone tumors. In 15 patients (3 malignant bone tumors and 12 solitary metastases), tumors were distributed in the thoracic (n = 8) and lumbar (n = 7) spine.

Postoperative epidural anesthesia preserves lymphocyte, but not monocyte, immune function after major spine surgery.

Unlabelled: Extensive spine surgery is associated with postsurgical pain. Epidural pain therapy may reduce postoperative stress responses and thereby influence immune functions. In a randomized, controlled, double-blinded prospective trial, 54 patients received either conventional patient-controlled IV analgesia (PCIA; morphine 3 mg/15 min) or patient-controlled epidural analgesia (PCEA; 0.
