Polokoff Bone File is a widely used instrument in surgery to aid in mild bone reshaping. Orthopedic neurosurgical procedures such as craniotomies or spinal surgeries such as discectomies require manipulation and handling of very delicate tissue such as nerves or brain tissue itself as well as a vast amount of vasculature. This file can be used to reshape or whittle down bone fragments that are sharp or jagged and could cause injury to any of the above tissue. Additionally this file is available with a short head and fine serrations or a long head with medium serrations.
