What is it indicated for?

The PASS Spinal System consists of pedicle screws, rods, nuts and crosslink members utilized to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of thoracic, lurmbar, and sacral spine: degenerative spondyiolisthesis with objective evidence of neurclogical impairment, fracture, dislocation, scoliosis, kyphosis…

Read the full statement (196 words)

The PASS Spinal System consists of pedicle screws, rods, nuts and crosslink members utilized to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of thoracic, lurmbar, and sacral spine: degenerative spondyiolisthesis with objective evidence of neurclogical impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis).

As a pedicle screw system, the PASS Spinal System is intended for the treatment of severe spondylolisthesis (Grade 3 and 4) of the L5-S1 vertebrae in skeletally mature patients receiving fuslon by autogenous bone graft having implants attached to the lumbar and sacral spine (L3 to sacrum) with removal of the implants after the attainment of a solid fusion.

When used as a posterior, non-cervical, non-pedicle screw fixation syste, the PASS Spinal System is intended for hook fixation from T1 to the ilium/sacrum. The non-pedicle screw indications are spondylolisthesis, degenerative disc disease (as defined by back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies), deformities (scoliosis, kyphosis and lordosis), tumor, pseudoarthrosis, trauma (fracture or dislocation) and/or previous failed fusion surgery.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
