Manufacturer Narrative
Analysis of historical records: orthofix (b)(4) checked the internal records related to the controls made on the axial screw code 53014 (which is the broken component of the clamp code 53530) lot v1398289 before the market release.No anomalies have been found.The original lot, manufactured in 2015, was comprised of (b)(4) units.All of them have already been distributed to the market.According to orthofix (b)(4) historical records, no other notifications have been received in regards to this specific device lot.Technical evaluation: the technical evaluation of the device involved will be performed as soon as the device becomes available.Medical evaluation: the information available on the case was sent to our medical evaluator.A preliminary medical evaluation was performed and will be finalized once further information on the event will be available.Orthofix (b)(4) has requested the distributor to provide further information on the event such as what treatment was being performed, when exactly did the screw break, copies of the pre and post operative x-rays (initial and second surgery), and device availability for the technical evaluation.Unfortunately this information has not yet been made available.As soon as further information is available, orthofix (b)(4) will provide you with a follow up report.Orthofix (b)(4) continues monitoring the devices on the market.
 
Event Description
The information provided by the local distributor indicates: product code: 53530 (adv straight clamp).Batch number of the axial screw code 53014: v1398289 (lot traced from combination of components during manufacturing).Qty: 1.Hospital name: (b)(6) hospital.Surgeon name: (b)(6).Date of initial surgery: (b)(6) 2016.Date of revision surgery: (b)(6) 2016 body part to which device was applied: left femur.Surgery description: screw was broken when submitted to torque.Patient information: (b)(6), male, in good health condition.Problem observed during: clinical use on patient.Event description: screw was broken when submitted to torque.It was replace to another dispositive.The device failure had adverse effects on patient (loss of distraction/correction achieved).The initial surgery was completed with device.The event did not lead to a clinically relevant increase in the duration of the surgical procedure.An additional surgery was required following device failure (performed on (b)(6) 2016).Copies of the operative reports and copies of the x-ray images are not available.Patient current health condition: submitted for a review.On (b)(6) 2016, orthofix (b)(4) received the following additional information: patient current state of health: the patient is recovering well.(b)(4).
