Manufacturer Narrative
As received condition of device: excessive force marks around the hexagon socket of the connecting screw, as well as the 11 mm hexagon profile below the handle grip.Product development event evaluation was completed: it was reported, that cold fusion occurred between the spherical head hex-screwdriver and the self retaining connecting screw.In consequence, the spherical end of the screwdriver broke off when trying to loosen the connecting screw.A note was added to the surgical technique, stating: ¿in case of difficulties to remove the connecting screw, push the insertion handle towards medial or lateral to neutralise soft tissue pressure.¿ device used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
 
Manufacturer Narrative
An investigation summary was performed.It was reported by the investigation of the complaint articles has shown that: the devices were received in an assembled condition; the insertion handle was still connected to the nail with the connection screw.The t-handle screwdriver was also send back and the complete spherical hexagon part is broken off, the fragment was enclosed.The manufacturing documents of all devices were reviewed and no complaint related issues were found.During the investigation it was possible to disassemble the devices with a straight standard hex-wrench by applying very high force.Afterwards it was possible to assemble and disassemble the devices as required.The review of the broken t-handle screwdriver has shown that the complete hexagon is broken off.The relevant dimensions at the fracture face cannot be verified anymore as the device did slightly twist at this point before it broke.The fracture face is homogenous, which indicates material conformity, and has the typical view of a forced rupture.Based on that, we conclude that the very high force that was applied onto the spherical shaped tip of the t-handle screwdriver during the attempt of loosening the connection screw did lead to the breakage of the device.However, based on the provided information we are not able to determine what finally caused the jamming between the nail, the insertion handle and the connection screw.One reason is possibly very strong tightening of the connection screw during assembling, which would explain the visible deformations at the broken hexagon and as well by the visible marks in clockwise direction of a wrench at the upper hexagon below the handle.An investigation that was performed on previous complaints has shown that also shown that soft tissue pressure can also lead to a jamming of the devices.Therefore a note was added to the tfna surgical technique guide, stating: ¿in case of difficulties to remove the connecting screw, push the insertion handle towards medial or lateral to neutralize soft tissue pressure.¿ device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
