The ISOLA Spinal System, when used with pedicle screws, is intended for use in grade 3 or 4 spondylolisthesis at the fifth lumbar - first sacral vertebral (L5-S1) joint utilizing autologous bone graft and intended to be removed after solid fusion is attained.

The ISOLA Spinal System, when not used with pedicle screws, is intended for hook, wire, and/or sacral/iliac screw fixation from T1 to the ilium/sacrum. The non-pedicle screw indications are spondylolisthesis, degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies), deformities (scoliosis, lordosis and kyphosis), tumor, fracture and previous failed surgery.

As a whole, the ISOLA Spinal System is intended for T1-sacral fixation. Screw fixation is from L3-S1.

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