(b)(4).No product will be returned as it remains in-situ, no product information was given, and no further evaluation of the product can be completed at this time.The condition of the implant upon re-insertion is unknown or how big a piece had broken off.It is undetermined if the allegation of incontinences and foot drop is the result of excessive or prolonged nerve retraction, the laminectomy, the discectomy, anatomical obstructions during the initial insertion of the cage, exploration and removal of the fragment, posterior fixation or otherwise a result of the overall procedure itself.The root cause of the issue is unknown, but may be the result of some action by the user or anatomical conditions of the patient.Peek implants can fracture and may be the consequence or result of incomplete device training or improper surgical technique (excessive force) or insufficient patient disc preparation allowing for proper insertion.Complaint monitoring will continue and additional action will be taken in the event that an adverse trend is identified.No additional action is planned at this time.Review of labeling notes: warning cautions and precautions "surgical outcomes with this device are significantly affected by the surgeon's proper patient selection, preoperative planning, proper surgical technique, proper selection and placement of implants and complete compliance of the patient.Selection of the proper size, shape, and design of the implant for each patient is extremely important and crucial to the success of the procedure.Implants are subject to repeated stresses in use, and their strength is limited by the size and shape of the human spine.".
