MTF G2 Allograft
The Musculoskeletal Transplant Foundation's (MTF) unparalleled reputation for tissue quality and safety is why Spineology chose to partner with MTF to provide G2 graft products.
G2 grafts are proprietary Granular Graft mixtures of Demineralized Bone Matrix (DBM) and corticocancellous chips.
G2 grafts come in two versions: AFT and Dry Mix.
AFT Features:
- Provided pre-packed into fill tubes with a Sodium Hyaluronate carrier to ease intraoperative handling
- Lot tested for osteoinductivity in addition to being osteoconductive
- Extensively tested prior to and after processing to insure safety
- Available for 1500E, 1500S, and 1500DS
Dry Mix Features:
- Extensively tested prior to and after processing to insure purity
- Easily mixed with autogenous materials intraoperatively
- Easily loaded into fill tubes intraoperatively
OptiMesh Labeling
INTENDED USE / INDICATIONS
OptiMesh is a surgical mesh intended to contain and reinforce bone grafting materials and/or bone graft substitutes in bony voids or gaps of the skeletal system (i.e., the extremities, spine, and pelvis). These voids or gaps may be surgically created osseous defects, natural gaps, or defects partially surrounded by bone, defects created from traumatic injury, or a combination thereof. Adjunct fixation is recommended in cases involving segmental instability.
OptiMesh is indicated for use in orthopedic grafting procedures, including the following:
Lumbar interbody fusion: The OptiMesh 1500 System is used to contain, enhance the compaction of, and stabilize and reinforce bone graft material used in the intervertebral space of patients undergoing fusion to treat degenerative disc disease at one spinal level from L2-S1. For this use, OptiMesh 1500 is to be used in conjunction with stabilizing posterior fixation.
Thoracolumbar vertebral body fractures: OptiMesh 1500 with allograft is intended for vertebral augmentation, including fracture reduction, for the treatment of painful insufficiency fractures of the vertebral body due to osteoporosis, minor trauma or benign lesions.
It is also intended for the treatment of painful traumatic vertebral fractures which are either a) clinically stable upon presentation, or b) are surgically stabilized with posterior fixation.

Granular Mechanics
A subspecialty of physics known as Granular Mechanics describes the unique physical characteristics of granular materials.
One useful characteristic of granular materials is their properties change when contained, i.e., flowable (liquid-like) to solid. OptiMesh utilizes this principle.
In an open environment, like the cannulae used to deliver bone into an OptiMesh, the bone granules can flow like a liquid and be pressurized to generate hydraulic-like lifting capabilities. Yet, when a space is enclosed, like the inside of an OptiMesh, the graft granules can be so densely compacted they point load and form force chains, making the graft pack act like a load-bearing solid structure.
