INTRODUCTION: Percutaneous needle trephination is a well known neurosurgical procedure. The aim of this study was to develop a new instrument, which allows a stable fixation of an 18-G spinal needle in order to improve handling and precision of percutaneous needle trephinations. METHODS AND INSTRUMENTATION: The needle stabilizer was designed in a T-shape fashion morphologically similar to a corkscrew. The length of the uncovered needle tip is adjustable for individual requirements. RESULTS: Using the new needle stabilizing device a total number of 18 percutaneous needle trephinations were performed for the following indications: subdural hematoma, epidural hygroma, bifrontal air accumulation, superficial tumor cyst, superficial brain abscess. No complications have been observed. DISCUSSION: Our experience using this device shows that the modified technique fulfils criteria for clinical acceptance such as simplicity, low risk, reliability and cost effectiveness.
