Pedicle Osteotomy for Stenosis Trial

Decompressive surgery via Pedicle lengthening osteotomy using Altum Device. Altum is intended for pedicle lengthening to correct degenerative lumbar spinal stenosis in the presence of a grade 1 degenerative spondylolisthesis. The Altum bone saw is designed for creating an osteotomy at the base of each pedicle. The Altum implant is designed for distraction of the pedicle osteotomy and for lengthening of the pedicles. Altum is appropriate for skeletally mature adults with symptomatic stenosis at one or two levels between L2-L5.
