Event or Problem Description
It was reported that, during an ankle arthroscopy, the tip of a ferkel microfracture pick broke within the patient's bone.After performing x-rays exam, it was decided to leave the foreign body in the bone as removing it would cause more damage.It is unknown how the surgery was completed, but the surgery was not significantly delayed as consequence of the allegation.The patient has recovered satisfactorily from the surgery.All available information has been disclosed.If additional information should become available, a supplemental report will be submitted accordingly.
Additional Manufacturer Narrative
The reported 90 degree ferkel microfracture pick, used in treatment, has not been returned for evaluation to the mansfield site.However a photograph was supplied.Examination of the photograph confirmed the reported complaint of the distal tip of the device breaking off.The device is over nine years old and has not had any previous incidents.An exact root cause cannot be determined with confidence; however, factors that could have contributed to the reported event include: excessive force applied during insertion.Improper site preparation.The instruction for use outlines precautionary statements and instructions in regards to the use of the device to avoid damage or non-functionality.A review of the manufacturing and complaint records was performed for the reported lot, there were no indications that would suggest that the device did not meet product specifications upon release into distribution.Further investigation is not warranted at this time.In conclusion: the definitive root cause of the pick fracture and subsequent retained foreign body (tip) could not be definitively concluded; however, arthroscopic instrument breakage is a known potential surgical complication and compliance use of instrument and/or pressure or application of excessive torque could have been contributing factors.Patient impact beyond the non-implantable retained foreign body could not be determined, although possible localized pain/discomfort, corrosion, micro-motion and/or migration of the broken tip could not be ruled out.It was communicated that the procedure was completed with the same device without any significant delay and reported the patient ¿recovered satisfactorily¿, adding, ¿this shouldn't cause the patient any issues¿.No further medical assessment can be rendered at this time.
