Opus BA
Osteoconductive Matrix

Opus™ BA is a synthetic bioactive solution that is easily hydrated and flexible. A carefully selected trifecta of components creates an ideal environment for bone growth building on the earlier generations of synthetic bone grafts.

Highlights

Carbonate Apatite Bone Mineral 50%

  • Higher osteoclastic and osteoblastic activity than β-TCP & HA1
  • Resorption & remodeling similar to human bone2,3

45S5 Bioactive Glass 30%

  • Ideal particle range and size (100-300μm)4,5,6 
  • Ability to stimulate the growth and osteogenic differentiation of osteoblasts7

Type 1 Collagen 20%

  • 100% resorbable8
  • Binds proteins and cells and retains biological factors9

Indications

Opus BA combined with either autogenous bone marrow or autograft with saline is indicated for bony voids or gaps, that are not intrinsic to the stability of the bony structure; Opus BA can also be used with autograft as a bone graft extender. The device is to be gently packed into bony voids or gaps of the skeletal system (i.e., posterolateral spine). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The device resorbs and is replaced with bone during the healing process.
