ApaPoreĀ is a synthetic and porous hydroxyapatite.
ApaPore is disease free, readily available and manufactured to a highly controlled specification providing a cost-effective bone graft.
Design Philosophy
ApaPore is as phase-pure as bone mineral, containing no secondary phases. ApaTech has shown that this maximises a favourable bony response.
Microporosity
ApaPore has a trabecular structure similar to that of cancellous bone.
- Trabeculae are highly microporous, up to 25% and
- Microporosity is interconnected, which
- Allows nutrient transfer to host bone and
- stimulates cell differentiation
Macroporosity
ApaPore has a macroporous structure second to none. The large macropores:
- Facilitate angiogenesis
- Avoid mechanical discontinuities
- Maintain long term osseous integration
Unlike other commercially available materials its porous structure is consistent, providing a controlled macroporosity within +/- 1% and no high standard deviations, giving a much more predictable bony response.
Interconnectivity
ApaPore has high levels of interconnectivity between micro and macropores. This network:
- Allows fast bone ingrowth
- Promotes revascularisation, essential to healthy bone
- Enhances long term graft stability
- Provides a continuous host bone/graft composite.
Ease of use
ApaPore absorbs blood, fat or bone marrow: a cohesive composition that is easy to shape and place. Combining ApaPore with either allograft or autograft bone is expected for all loaded applications.
Surgical applications include:
Indications for Use: Europe & Australia
Bone graft substitutes are intended to be used in place of cortico-cancellous, or cancellous allograft bone (human bone from a bone bank).
The mechanical environment for such uses see either low load requirements or compression.
Typical surgical applications for bone graft substitutes are
- Small void filling, e.g. after removal of a small bone tumour or following bone fracture reduction or in osteotomies and plastic surgery.
- As an allograft extender (bulking material or dilutant) when there is insufficient allograft available, e.g., spinal fusion, or revision of failed joint replacement arthroplasty using impaction grafting.
It is not intended to be used in place of cortical strut allograft bone where high tensile and bending characteristics are required.
ApaPore is not currently available in U.S.
