A review of the device history record confirmed that the device was manufactured and tested according to relevant procedures, and shipped according to manufacturer's specifications.Patient (b)(6) index procedure performed on (b)(6) 2021 on (b)(6) 2023, apifix was notified that patient (b)(6) has developed significant proximal junctional kyphosis, pjk, ( t8-t10, treated with extender lenke 5) and that the surgeon will most probably remove the device in 6 months (~ 3y post op).The correction of the curve in the ap is good per the doctor's measurements.On (b)(6) 2024 apifix was notified that patient (b)(6) would be having their apifix device removed at the end of the month.The surgeon wanted to monitor the device for another six months. it has now been six months since that follow up and the surgeon has decided to remove the device.On (b)(6) 2024 apifix was notified that patient #491 implant was removed on (b)(6) 2024 as planned.It was further reported that the device was undamaged, and the reason for removal was "pain after significant weight gain & increased kite angle." the risk of pain is a known risk.Pain associated with scoliosis is well described in the literature regardless of having corrective surgery.Pain can also be a transient complaint associated with the surgical procedure or be secondary to device failure, infection/inflammation, curve progression, screw pull-out, loosening, migration, protrusion, and prominence.The event of pain is addressed in the ifu as a warning and as potential risks associated with the mid-c system and spinal surgery generally.The risk of curve progression is a known risk. the event of spine imbalance is addressed in the ifu as potential risks associated with the mid-c system and spinal surgery generally section.Spine imbalance post-surgery can result from curve progression, improper device use, or treating not within the indications for use.Imbalance can also be an aggravation of a pre-op condition.The risks have been characterized and documented as acceptable within full risk assessment.The explanted device is expected to be returned to the manufacturer and will be evaluated; upon its completion, once new information comes to light, then a supplemental medwatch report will be submitted.
