3D-printed Porous Titanium Alloy Cages Versus PEEK Cages in Patients With Osteoporosis

NCT04086784 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 90

No results posted yet for this study

Summary

This is a prospective,observational single-center study. The osteoporotic patients requiring posterior lumbar interbody fusion(PLIF) with cages at the lowest fusion segment are prospectively enrolled and followed up. The patients undergoing PLIF with the 3D-printed porous titanium alloy cages are compared with those using PEEK cages. The hypothesis is that the use of 3D-printed porous titanium alloy cages can reduce the rate of pedicle screw loosening and increase the rate of lumbar fusion in osteoporotic patients.
