A pick device for debriding and preparing a bone surface has a handle, a cannulated debridement shaft and a drill wire. The shaft has an open lumen to receive a drill wire through a proximal end of the handle. The drill wire has a tip end to scrape bone surfaces to create micro-fractures to enhance tissue and cell regeneration. The distal tip can be oriented and provided in a pre-set angle of 30, 45 or 60 degrees relative to the cannulated shaft. The drill wire has a diameter of at least 1.0 mm, preferably in a range of 1 to 3 mm and most preferably 1.45 mm and flexibly bends at the removable distal tip. The drill wire is made of Nitinol, has a stop affixed to the proximal end to limit micro-fracture penetration at the distal end and the distal end has a trocar tip to cut bone tissue.
