The Unity® Lumbosacral Fixation System offers Unity 51 & Unity LX, two unique plates with low-profile design that can be used independently or jointly. The system maximizes anterior column stabilization while minimizing the challenges of an anterior approach to lumbosacral fixation. Strong, flexible, and secure, the Unity Lumbosacral Fixation System’s plate design facilitates stability with a claw-like grip.
The Unity 51® plate supports rigid single-level L5 – S1 fixation with a robust anatomically compatible design. The plate features a caudal lip that “hugs” the sacrum for easier alignment and 6.0mm and 7.0mm diameter angled screws maximize purchase. Top-locking plate reduces the potential for screw back-out. Two lengths of various instrumentation address different anatomical sizes.
The Unity LX® plate is designed for use at the lumbar levels above L5 – S1. Available in six heights, the Unity LX plate offers a low profile design with easy-to-read directional arrows on the plate surface which ensure proper construct set-up. Based on patient need and surgeon preference, the plate can be placed anteriorly or anterolaterally.
Bone screws with variable angle insertion maximize purchase
Optional anterior or anterolateral placement for intraoperative flexibility
The Orthofix Unity 51 Lumbosacral Fixation Plate is indicated for use as an anteriorly placed supplemental fixation device for the lumbosacral (L5-S1) level below the bifurcation of the vascular structures. The Orthofix Unity LX Lumbar Fixation Plate is indicated for use as an anteriorly or anterolaterally placed supplemental fixation device for the lumbar region of the spine above the bifurcation of the vascular structures. When properly used, this system will help provide temporary stabilization until a solid spinal fusion develops. Specific indications include:
Degenerative disc disease (defined as back pain of discogenic origin with degenerative disc confirmed by history and radiographic studies)
Unsuccessful previous fusion surgery
Lordotic deformities of the spine
Idiopathic thoracolumbar or lumbar scoliosis
Deformities (i.e., scoliosis, kyphosis, and/or lordosis) associated with deficient posterior elements such as that resulting from laminectomy, spina bifida, or myelomenigocele
The Orthofix Unity Lumbosacral Fixation System is contraindicated in patients with a systemic infection, with a local inflammation at the bone site, or with rapidly progressive joint disease or bone absorption syndromes such as Paget’s disease, osteopenia, osteoporosis, or osteomyelitis. Do not use this system in patients with known or suspected metal allergies. Use of the system is also contraindicated in patients with any other medical, surgical or psychological condition that would preclude potential benefits of internal fixation surgery such as the presence of tumors, congenital abnormalities, elevation of sedimentation rate unexplained by other disease, elevation of white blood cells or a marked shift in white blood cell differential count.
