GIZA Vertebral Body Replacement

Complaints that implants have been disassembled by surgeons because of unscrewing completely the locking screw.

A correction letter to the users was sent on March 28, 2017 Stating the following: Eden Spine Europe has become aware of extremely rare incidents of disassembly of Giza devices, which is distributed by Stryker Spine in the USA. These incidents have occurred in limited situations when a surgeon has needed to unscrew the device in order to readjust the distraction. To mitigate this risk, a more precise description of the unlocking procedure in the Giza Surgical Technique was added to prevent surgeons from fully unscrewing the locking screw. POTENTIAL HAZARD In the unlikely event the Giza device was to disassemble, the potential hazard is that the surgeon may decide either to reassemble the device or change the implant to a new device. This could potentially lead to a short surgical time delay of 2 to 10 minutes. RISK MITIGATIONS Eden Spine Europe and Stryker have added the following information in the Giza Surgical Technique to mitigate the risk of disassembly of the device: Note: If adjustment is needed, the implant locking mechanism must be unscrewed 3.5 to 4 rotations from the tightened position, to free the superior cylinder from the inferior one. No more than 4 counterclockwise rotations should be applied to the locking screw, as doing so could potentially lead to disassembly of the implant's locking mechanism. The GIZATM Vertebral Body Replacement surgical technique is available on Stryke Spine's website.
