Blocks, Dowels & Cortical Struts

Blocks, dowels and struts bone grafts cut into specific sizes and shapes. These are grafts that are generally not possible to obtain as autografts. We can also create custom made grafts (e.g., wedges, short sections, etc.) for specific applications.

Advantages

	Available in different sizes.

	Not generally available as autograft.

	Can be trimmed to fit recipient site.

	Biological repair – fuses with, and eventually replaced by, the recipient’s own bone.

Common Applications


	Spinal fusions, periodontics (Cancellous Blocks, Dowels or Bergman Blocks)

	Void filling (Cancellous Blocks or Dowels)

	Bone loss (Bergman Blocks)

	Buttressing to augment existing weak bone structure (Cortical Struts)

Composition


	Cancellous Blocks and Dowels are made from extremely dense cancellous bone typically found in the condyles and plateaus of femur and tibia. Ulnar dowels are cut as cortical rings of ulna.

	Bergman Blocks are short cortical segments (<3cm) of tibia, femur, humerus or radius.

	Cortical Struts are longitudinal sections of cortical bone from canine tibia, radius, or femur. They will have a flat to semi-round cross-section. The thickness of the cortex will be at least 3mm. They are either ~0.5 or 1.0cm wide and ~3.0 - 5.0cm in length.

Storage


	Blocks, Dowels and Cortical Struts should be kept frozen (at least at -20°C) until ready for use. If stored at -20°C (or in a standard household freezer), they should be used within 6 months of receipt. If stored at -40°C or colder, the grafts can be stored for 5 years.
