Int.Ref.: (b)(4).In digitaldiagnost systems, there are two types of detectors: portable and fixed.The portable skyplate detectors can be used for free exposures and can be removed from the bucky unit.The fixed detectors are permanently installed in the bucky unit subsystem.The bucky unit for fixed detectors has a metal center indicator which is used to locate the center of the detector when direct view is blocked by the table.This facilitates proper patient positioning in relation to the detector and the tube assembly so that the anatomy of interest is centered upon image.The center indicator is located on the bottom of the bucky unit and protrudes approximately 6 mm from the front panel for ease of access.During use, the center indicator is swung out of its parking position so that it is positioned parallel to the floor and extended from the table.The customer reported taking free exposures of a patient's hand/finger with the portable skyplate detector.The skyplate detector was placed on the table directly above the fixed bucky unit.The patient was positioned in front of the table with his/her legs facing the table base with the fixed bucky unit.For the final projection, the patient was asked to turn to his left side.While turning, the patient made contact with the parked center indicator resulting in a cut to the patient¿s knee.The cut required medical attention.The investigation revealed that there was no system malfunction.The patient's injury was exacerbated due to the patient positioning.Free exposure of a patient may occur, although less common than with use of the fixed bucky unit, and is anticipated for imaging of smaller anatomy (i.E.Hand or elbow).The conventional patient positioning under this scenario has the patient sitting near the short side of the table as this provides sufficient room for the patient¿s knee.During this hazardous situation, the patient was positioned in proximity to the center of the table, where the foot switches for table movement and the center indicator are located.The suboptimal patient positioning resulted in the inadvertent patient injury.As a result, the customer decided to remove the centering indicator and use the tray drive function for alignment purposes only.Risk estimation determined that no unacceptable risk was present.Going forward, the issue shall be further monitored and trended.The event was originally reported to the authorities as not enough information was available to make a definite reportability decision.Since that time, additional information was received which revealed that the event does not meet the criteria for reporting.Correction: h1 from seroíous injury to injury.H6 patient, result and conclusion code.
