Whether joint replacement is possible after failed lumbar implant fusion needs to be decided according to the postoperative condition and individual’s physical fitness. Patients with surgical failure can be treated conservatively or surgically first. If the conservative treatment is ineffective for 3 months and there are obvious symptoms of nerve compression, spinal stenosis, postoperative lumbar instability and any other symptoms, joint replacement can be considered again.
Conservative treatment includes medication, prolonged bed rest, rehabilitation training, etc. Failure of implant fusion without nerve compression can be treated conservatively, with regular review, close observation of recovery, and downward mobility under the protection of lumbar support.
Surgery itself has its own risks and needs to be considered in light of changes in the condition. If the lumbar spine is destabilized due to loosened or broken internal fixation, and the nerves and spinal cord are obviously compressed, resulting in leg pain and numbness or even the inability to walk, then revision surgery can be performed to replace the joints again.
If the lumbar implant fusion fails, it is recommended to consult a doctor for further treatment. Daily activities should pay attention to the intensity, should not be strenuous exercise, to avoid affecting the postoperative recovery.
