Internal fixation is a common orthopedic procedure in which a rigid screw is\nused to fix fragments of a fractured bone together and expedite the healing\nprocess. However, the rigidity of the screw, geometry of the fractured anatomy\n(e.g. femur and pelvis), and patient age can cause an array of complications\nduring screw placement, such as improper fracture healing due to misalignment\nof the bone fragments, lengthy procedure time and subsequently high radiation\nexposure. To address these issues, we propose a minimally invasive\nrobot-assisted procedure comprising of a continuum robot, called ortho-snake,\ntogether with a novel bendable medical screw (BMS) for fixating the fractures.\nWe describe the implementation of a curved drilling technique and focus on the\ndesign, manufacturing, and evaluation of a novel BMS, which can passively morph\ninto the drilled curved tunnels with various curvatures. We evaluate the\nperformance and efficacy of the proposed BMS using both finite element\nsimulations as well as experiments conducted on synthetic bone samples.\n
