The solitaire 25mm fishtail drill, rigid, item # 1400-9213, lot # 019337 was returned for evaluation.Visual inspection of the item shows the tip of the drill has fractured in a manner consistent with excessive torque forces applied to the drill.The missing portion of the drill was not returned.A function check of the returned item cannot be performed because the drilling tip of the device is missing.The length of the device was measured at 10.630¿.The device drawing specifies the length as 11.50¿, indicating approximately 0.870¿ of the drill is missing.Per the complaint, the missing drill tip was retained in the patient, and that the patient had very hard bone.The dhr (device history record) was reviewed; the drills were received and inspected with no non-conformances noted.The hardness measured within the specification for the device.The probable underlying root cause for the damage is excessive torque applied to the drill during use leading to loss of mechanical integrity and ultimately instrument deformation and fracture.Contributing factors include patient condition (hard bone, etc.).
