Use of Osteoplug TM polycaprolactone implants as novel burr-hole covers

Introduction: The aim of this study was to evaluate the outcome of Osteoplug TM , a novel biodegradable polymer burr-hole cover implant, used in patients with burr holes done for drainage of chronic subdural haematoma. Methods: 12 patients with chronic subdural haematoma had Osteoplug TM implants inserted into their burr holes after evacuation of the haematoma. Osteoplug TM is a biodegradable polycaprolactone implant with a mushroombutton shape, designed specifically to fit into a 14-mm diameter burr hole. It has an upper rim of 16-mm diameter and a body diameter of 14 mm, with a honeycomb-like architecture of 400–600 μm pore size. The Osteoplug TM
