Posterior spinal instrumentation and fusion (PSIF), also called spinal fusion, is a procedure to put the bones of the spine (vertebrae) into the correct position. The surgeon straightens the spine by fusing some of the bones in the back together with bone grafts and implants (including special rods and screws). Why do I need spinal fusion surgery?

2024年11月14日 · Posterior Spinal Fusion (PSIF) is a surgical procedure used to treat scoliosis, a sideways curvature of the spine. PSIF involves fusing together vertebrae in the spine, limiting …

2016年4月18日 · PSIF system allows the surgeon to take a familiar posterior approach to fusing the SI Joint. Unlike the challenging lateral approach to fixate the SI Joint, PSIF is a safe and extremely reproducible surgical procedure. The PSIF system uses allograft bone, which included much discussion over many hours before determining final allograft bone design.

2023年5月23日 · Transforaminal lumbar interbody fusion (TLIF) is a spinal fusion technique for the lower back, in which two spinal bones (vertebrae) are joined by removing a portion of the spinal disc between them and placing a spacer (cage), supplemented by screws and rods, in …

Why PsiF? Simple: Single implant size (8x10x25mm) made of structural allograft bone and shaped for easy posterior insertion into the SI joint. Reproducible: Familiar prone patient position for identifiable landmarks and instrumentation that …

The PsiF system is a viable solution for patients with sacroiliac joint dysfunction who have exhausted non-surgical treatment options. This innovative system enables physicians to stabilize the SI joint through a minimally invasive posterior approach, providing patients with immediate pain relief and improved function.

2023年7月14日 · (1) Background: Minimally invasive sacroiliac joint (SIJ) fusion is the preferred surgical intervention to treat chronically severe pain associated with SIJ degeneration and dysfunction. (2) Methods: This paper details the ten-step surgical procedure associated with the postero-inferior approach using the PsiF™ DNA Sacroiliac Joint Fusion System.

Posterior-only surgery, instrumentation and fusion have become the preferred technique in many centers throughout the world due to simplicity of approach, decreased risk of certain complications and the correction power of pedicle screws.

Posterior Instrumented Fusion (PSIF) A procedure where screws are put in bone to take away painful motion and/or to add stability. Typically cartilage is burred and bone graft is added for a fusion to occur. This can be done at 1 or multiple levels.

2022年9月22日 · The PsiF or Posterior Sacroiliac Blend System is a clinical device used to deal with SI joint dysfunction and also SI joint pain. The specialized allograft implant is utilized to fuse the SI joint, providing it with stabilization, and relieving SI joint pain.
