DOI: 10.1007/s00586-018-5592-2
Abstract: PurposeSpinal fusion is used for treatment of spinal deformities, degeneration, infection, malignancy, and trauma. Reduction of motion enables osseous fusion and permanent stabilization of segments, compromised by loosening of the pedicle screws (PS). Deep implant… read more here.
