Event Description

It was reported that during the total hip replacement surgery, after measurement, the insert 60mm was chosen to be used.While implanting, the insert was completely inside the cup, but it was not close to fit, it could still be moved.A call for help from the s&n was done and it was informed that it could be re-implanted after soaking in ice water, but after soaking in the ice water for 5 minutes, the situation occurred again.Then, it was tried to soak it in hot water, and it still could not be tightened.After repeated trials for more than an hour, the patient had already had a lot of bleeding.Inquiring the s&n again, it was decided to change the cup and failed again.At that time, the patient had more blood loss and arrhythmia.Then the surgeon had to take out the acetabular prosthesis, replaced it with the 62mm acetabular cup prosthesis, and successfully implanted the 62mm high cross-linked liner.The surgery was completed after more than 2 hours delay.

Manufacturer Narrative

It was reported that the 60mm insert was inside the cup when implanting, but it was not close to fit; it could still be moved.The surgeon had to replace it with the 62mm cup, and successfully implanted the 62mm liner.The affected r3 acetabular liner, r3 ceramic liner and r3 three hole acetabular shell, used intreatment, were returned.A lab report noted yellowish staining in the porous region of the shell.This is most likely to be biological in nature from body contact during the procedure.Scratches were found the liner and ceramic liner, which possibly occurred from instrument contact during the procedure.A review of the manufacturing records for the listed batches did not reveal any deviation from the standard manufacturing processes.A review of the complaint history for the listed parts revealed no prior complaints for this failure mode.Dimensional analysis performed on the shell and the liner noted the critical locking features were within spec.The supplier found no deviations on the ceramic liner during manufacturing.At this time, we have no reason to suspect that the products failed to meet any product specifications at the time of manufacture.A relationship, if any, between the devices and the reported event could not be corroborated.No medical documents were received for investigation.Therefore no medical assessment can be performed at this time.The root cause of the connection problem could not be determined.However, a user/procedural variance cannot be ruled out as a contributing factor.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.Smith and nephew will continue to monitor for future complaints and investigate as necessary.
