From staff: surgeon operating on pt's hip and surgical instrument (torque screwdriver) broke.From op report: complications: broken screw driver tip that prolonged case.I was eventually able to remove trial cone body.Initially i could not engage the threads to remove the trial component since the tip of screw driver had sheared off.We attempted to remove entire construct, but the distal stem was well engaged.I irrigated the region where the screw driver is inserted, and this appeared to clear the hole.I was able to engage a new screw driver to loosen the proximal body trial.The articulating surface region was visible inspected as well as palpated.We did not visualize the broken piece within the surgical site.Post-op xrays showed no evidence of the broken piece within the patient's body.Manufacturer response for 3.5 hex screwdriver, (brand not provided) (per site reporter).Zimmer rep took pieces.He was in the room for the case as well.
