Beginning (b)(6) 2012, us and (b)(6) customers were sent an urgent pt safety advisory informing them of the need for proper care and preventative maintenance of their zimmer air dermatome.Customers were informed that improperly maintained instruments may cause donor site injuries or result in damage to the graft.Customers were requested to contact zimmer to schedule maintenance for the device in accordance with the instructions for use.The device was returned to the mfr for repair and eval.The service record indicates that the device was manufactured on 08/15/1994 and has no repair history at zimmer surgical.Eval of the device observed nicks along the leading edge of the control bar and wear to the ears and leading edge of the head.It was also noted that this device had older style of reciprocating arm and thickness control lever.The master blade was flushed and the motor speed was within specs.It was observed that there was an air leakage at the connection between the hand piece housing and neck of the device.Prior to repair, the device was outside calibration spec on the left side at zero and 0.0200" thickness settings.Side to side calibration failed at all tested thickness settings.The customer's reported event could not be determined; however, lack of preventative maintenance could have caused the internal damage to the motor over time, potentially leading to intermittent failure.The cause of the damage to the head and lack of calibration is likely due to the user not maintaining the device per preventative maintenance and improper handling.
