Each revision procedure will vary based on the individual needs of the patient, but they will likely have two of the same goals: Oftentimes these two points go hand-in-hand, because you can add stability to an area by replacing damaged hardware that is no longer helping to provide support. The relatively low related coefficients might be due to the existence of numerous confounding factors, and these results indicated that the failure risk of instrumentation increased with age and osteopenia/osteoporosis, which was widely credited but rarely proven in vivo with mechanical measurement. Pedicle screw loosening is a common complication after spine surgeries. Can screws come loose after spinal fusion? Definition of screw loosening in spinal instrumentation. Some patients with this ailment have no symptoms, while others have back, neck, arm, or leg discomfort. 2009;18(10):148693.

A non-union occurs when a spinal fusion procedure fails and the vertebral bones do not fuse together successfully. If this happens, it may result not only with new back pain but also an increase chances for FBSS (failed surgery syndrome). Pedicle screws of non-fusion surgery placed in fractured vertebrae had significantly lower extraction torque and, therefore, could be vulnerable to loosening. There was no linear correlation between extraction torque and patients height (p=0.848), weight (p=0.196), BMI (p=0.125), and time interval between the primary surgery and screw removal surgery (p=0.965).
