Updated for that medwatch report product not returned to the manufacturer then no visual examination could be performed.The surgeon inserted the cage and proceeded to anchor impaction.He noticed that the hole of the threaded rod was cracked when he retrieved the implant holder.The plates and cage were took off and replaced by a similar implant.No impact on the patient.From information initially received, the surgeon decided to not use the starter awl (instrument used to create path and ease insertion of anchoring plate).As described in the surgical technique of roi-a device family, in order to prepare the anchoring plate trajectory, the starter awl is recommended for each roi-a surgery.Then starter awls should have been used by surgeon to create a completed path and avoid the breakage of the cage due to patient hard bone ( case of patient with sclerotic bones.) root cause is related to a user error, investigation found no evidence to indicate a device issue.Not returned to manufacturer.
