The device met print specifications where measured.The instrument returned was confirmed to be broken/fractured.As returned, the lag screw inserter was fractured near the lag screw connection end.There are some minor scuffs on the inserter especially in the connection regions.The device was used for treatment.The scuffs indicate previous effective use of the inserter over its potential field age of approximately six years.Excessive torque loads may damage the screw inserter if applied in an off-axis manner or if the inserter is used without being fully seated on the lag screw.If the patient had hard bone, it may have also contributed to the fracture of the device.The usage history of the inserter is not known.A definitive root cause cannot be determined.This mdr was identified during an internal retrospective review to meet reporting requirements and therefore is being filed retrospectively.
