From spine and sports medicine to dental and trauma, surgeons depend on tissue solutions with predictable handling, validated processing, and clear documentation. This guide breaks down 12 major Graft categories—what they are, where they fit, and how to decide—while showing how strong Donor Services support keeps your team compliant and ready.
The biology behind a better Graft
Successful bone healing blends three mechanisms:
- Osteoconduction: a scaffold that supports new bone ingrowth.
- Osteoinduction: signals (e.g., BMPs within demineralized matrices) that recruit and direct cells.
- Osteogenesis: living cells that can directly form bone (present in some cellular allografts).
Understanding which mechanisms your procedure needs helps you quickly narrow Graft choices.
1) Cortical Bone Allograft
What it is: Dense, load-bearing bone from the cortical shell (e.g., plates, rings, struts).
Best for: Structural support—spine fusion adjuncts, long-bone reconstruction, foot & ankle osteotomies.
Why choose it: High strength and slower remodeling for shape retention.
Watch-outs: Longer incorporation timelines; careful shaping required. Robust Donor Services documentation is essential for traceability given the structural role.
2) Cancellous Bone Allograft
What it is: Porous trabecular bone (chips, crushed).
Best for: Filling non-structural defects, promoting osteoconduction in fusion beds or fractures.
Why choose it: Excellent surface area for vascular ingrowth; handles quickly.
Watch-outs: Not for primary load-bearing; pair with fixation or structural elements when needed.
3) Corticocancellous Blocks & Wedges
What it is: Composite pieces that combine cortical strength with cancellous porosity.
Best for: Foot & ankle wedges, dental ridge augmentation, spinal posterolateral fusion beds.
Why choose it: Balanced strength plus biologic friendliness.
Watch-outs: Size/shape selection is key; confirm inventory with Donor Services to avoid intraoperative reshaping delays.
4) Structural Allograft Struts & Spacers
What it is: Pre-shaped structural pieces (e.g., fibular struts, femoral heads, interbody-type spacers).
Best for: Segmental defects, anterior column support, complex recon.
Why choose it: Immediate stability; radiolucent alternative to certain implants.
Watch-outs: Precise sizing and validation summaries matter; align with your hospital’s acceptance criteria and Donor Services documentation packets.
5) Particulate Bone Chips & Morselized Grafts
What it is: Small particles optimized for packing into irregular defects.
Best for: Augmenting fusion beds, filling cavitary defects, combining with biologics.
Why choose it: Packs tightly; conforms to anatomy; easy handling.
Watch-outs: Biomechanically non-structural—use with fixation or structural grafts.
6) Demineralized Bone Matrix (DBM) — Fibers, Putty, Paste
What it is: Allograft bone processed to remove mineral while retaining organic matrix with osteoinductive potential; delivered as fibers, putties, or pastes (often with carriers).
Best for: Spine posterolateral fusion adjunct, trauma void fill, dental defects.
Why choose it: Osteoinductive potential plus moldability and ease of placement.
Watch-outs: Carrier choice affects handling and graft volume; ask for lot-specific details and validation data through Donor Services.
7) Demineralized Cortical Fibers (DCF)
What it is: Long, interlocking DBM fibers forming a cohesive, moldable scaffold.
Best for: Fusion beds needing both scaffolding and easy contouring.
Why choose it: Excellent packing characteristics; resists migration; high surface area.
Watch-outs: Hydration technique matters—follow IFU closely for consistency across cases.
8) Cellular Bone Allograft (CBA)
What it is: Allograft matrices with viable osteogenic cells preserved under controlled conditions.
Best for: Revision cases, compromised host beds, situations needing osteogenesis plus osteoinduction/-conduction.
Why choose it: Delivers all three bone-healing mechanisms in one product class.
Watch-outs: Storage/handling (often cryo or refrigerated) and chain-of-custody are critical—coordinate tightly with Donor Services for transport, thawing, and documentation.
9) Osteochondral Allograft (OCA) Plugs & Blocks
What it is: Fresh/fresh-stored bone with articular cartilage for joint surface restoration.
Best for: Focal cartilage defects (knee, ankle), revision scenarios.
Why choose it: Restores native hyaline cartilage with congruent geometry.
Watch-outs: Availability windows, size matching, and timing are everything—lean on Donor Services for fit-finding and surgical scheduling.
10) Tendon & Ligament Allografts
What it is: Soft-tissue grafts (e.g., tibialis anterior/posterior, Achilles, semitendinosus) for ligament or tendon reconstruction.
Best for: ACL/PCL/MCL, shoulder stabilization, foot & ankle tendon repairs.
Why choose it: Eliminates donor site morbidity; reliable sizes; time-efficient.
Watch-outs: Sterilization method can influence tensile properties; confirm processing and validated strength profiles in your Donor Services packet.
11) Acellular Dermal Matrix (ADM)
What it is: Decellularized dermis preserving extracellular matrix architecture.
Best for: Soft-tissue reinforcement (shoulder, hernia, breast reconstruction), wound coverage.
Why choose it: Robust scaffold for revascularization and host integration.
Watch-outs: Hydration and suture-holding vary by thickness; confirm handling tips and orientation marks before opening.
12) Amniotic Membrane (Amnion/Chorion) Allografts
What it is: Placental-derived membranes supplied dehydrated or cryopreserved.
Best for: Anti-adhesion barriers, wound care, ophthalmic and certain dental/regenerative applications.
Why choose it: Natural barrier function and growth-factor profile.
Watch-outs: Indication-specific IFUs; ensure storage and sterility parameters are followed precisely.
Sterilization, SAL, and what it means in the OR
When comparing Graft options, ask for:
- Processing method & validation summaries: What sterility assurance level (SAL) is achieved?
- Biomechanical data: Especially for structural pieces and tendons.
- Residuals & biocompatibility testing: Important for grafts with carriers or unique chemistries.
A high-reliability Donor Services team will proactively share these documents, along with lot-specific certificates and traceability data.
Handling & storage that protect your timeline
- Temperature control: Follow storage labels (ambient, refrigerated, or frozen).
- Hydration discipline: Use recommended solutions/volumes and timing to preserve handling and performance.
- OR sequencing: Open and prepare the Graft only when fixation and bed prep are ready, reducing desiccation and waste.
- Label scanning: Capture UDI/barcodes into your EMR to lock in traceability.
Matching the Graft to the indication
- Need structure? Cortical, corticocancellous, or structural allograft struts.
- Need fill and contour? Cancellous chips, particulate grafts, or DBM/DCF for cohesive packing.
- Need biology super-charged? Consider CBA where osteogenesis may help, especially in revisions or compromised bone beds.
- Cartilage restoration? OCA with precise size matching and scheduling coordination.
- Soft-tissue reinforcement or reconstruction? Tendons for ligament repair; ADM for reinforcement; amnion for barriers or specific regenerative roles.

FAQ: Graft Selection & Donor Services
Q1: How do I decide between DBM putty and demineralized cortical fibers?
DBM putty offers moldability and easy syringe/knife delivery, while fibers interlock to resist migration and can hold shape in larger defects. Choose based on defect geometry and your preference for cohesive packing.
Q2: When should I consider a cellular bone allograft (CBA)?
CBA is worth considering in revisions, smokers, multi-level fusions, or cases with compromised biology—situations where osteogenesis could complement osteoinduction and osteoconduction.
Q3: Do structural allografts replace the need for implants?
Sometimes yes (e.g., fibular struts for segmental defects), but often they complement fixation. Selection depends on load, alignment goals, and surgeon preference. Always review mechanical validation data.
Q4: What Donor Services details matter most at audit time?
Lot traceability from donor to recipient, SAL and processing validations, temperature logs (if applicable), UDI/label captures, and complete certificates of compliance. These documents should be retrievable within minutes.
Q5: How can I reduce graft waste in dental and ASC settings?
Stock smaller, procedure-matched sizes; use just-in-time ordering for low-frequency SKUs; and train staff on hydration/open-time discipline. Ask Donor Services for historical usage to tune your par levels.
