A Broken Drill-bit Fragment Causing Severe Radiating Pain after Cervical Total Disc Replacement: A Case Report

Removal of Broken Cannulated Drill Bit

Breaking of surgical drill bits and subsequent dislodging in the bone are quite common in the field of orthopedics. Even though a few methods have been reported to remove dislodged drill bits, we present a novel method to remove a broken drill bit without additional instruments or a secondary incision. A broken cannulated drill bit within the locking screw hole inside the neck of a femur was retrieved using a depth gauge with a curved tip that hooked onto the edge of the drill bit. By employing a clockwise and counter-clockwise twisting, the broken drill bit was retrieved through the proximal reaming tract. The 4mm tract, which was established by proximal reaming, immensely facilitated safe and time-efficient removal of the drill tip without further trauma or prolonging the surgery time. With our technique, the removal was simple and safe without further soft tissue trauma and blood loss. We advocate this approach for implementation in similar cases.
