INTRODUCTION: The aim of this study was to improve the management of cervical tumor osteolysis. A new modular rod-screw implant system for the posterior instrumentation of the occipito-cervical, cervical and cervico-thoracic spine (neon occipito cervical system, Ulrich, Germany) is available since 2000. K-wire guided pedicle screws are used, CT-guided instrumentation is possible. Previous studies have demonstrated increased biomechanical stability compared to established posterior cervical systems. METHODS: The cervical and cervico-thoracic spine of 8 patients (6 males, 2 females, mean age 62 years, range 48-77 years) with osteolysis due to plasmocytoma (n=2), bronchial (n=2), mammary (n=2), esophageal (n=1) and pancreatic (n=1) carcinoma were instrumentated since June 2001. RESULTS: A stable fixation without loosening or failure of the fixation system was achieved in all cases. No impairment of the neurogical status was observed. CONCLUSION: Posterior instrumentation of the cervical spine including the occipito-cervical and the cervico-thoracic region with a new modular angle-stable rod-screw implant system offers good stabilization and allows simultaneous decompression. Since tumor masses are predominantly located in the anterior portion of the spine blood loss can be reduced
