The Pain, Life Quality and Low Back Pain Disability of the Patients Who Received Endoscopic Lumbar Intervertebral Fusion With Cages Made of Metal Material Versus Calf Bone: a Real World Study

Abstract

Background Interbody fusion is a common operation in spinal surgery, which is often used for various causes such as vertebral instability caused by trauma or degeneration. At present, a new material of calf bone interbody fusion cage has been used in clinic, but the curative effect has not been reported yet. In this study, the traditional metal interbody fusion cage was used as the control to evaluate the curative effect of this new type of interbody fusion cage. Method This retrospective non-blind case-control study included 96 patients with lumbar degeneration who underwent single segmental interbody fusion. Among them, 58 cases used calf bone material interbody fusion cage and used metal material (titanium) in 38 cases. The Visual Analogue Score (VAS) and Oswestry Disability Index (ODI) score were compared before, immediately after, 3 months after, 1 year after operation and the last follow-up. IBM SPSS is used to compare the collected data one by one, and the parameter samples are tested by independent-samples t-test. Result There was no significant statistical difference between patients who received calf bone fusion cage and metal fusion cage in each follow-up time point.Conclusion The curative effect of calf bone fusion cage was not inferior to that of traditional metal interbody fusion cage at each follow-up time.
