ARCA BONE

Product catalog summary

Introduction
The document discusses synthetic bone substitutes, focusing on hydroxyapatite (HA) and tricalcium phosphate (βTCP), which are known for their biocompatibility and osteointegration. These materials are used in biphasic ceramics for bone grafting.

ARCA BONE Technical Characteristics

Composition: ARCA BONE is a macroporous biphasic ceramic composed of 75% hydroxyapatite and 25% tricalcium phosphate.
Porosity: The porosity is fully interconnected, ranging from 60% to 80%, with pore sizes between 200-500 µm, suitable for human bone cells.

Biocompatibility
ARCA BONE shows excellent integration in both cortical and cancellous bone when implanted in sheep condyles. Key processes include:

Osteoconduction: After 6 weeks, new bone formation progresses centripetally through the macropores.
Osteointegration: By 12 weeks, the graft is fully colonized by bone tissue without fibrous tissue interposition.
Resorption-Remodeling: The ceramic structure begins to resorb after 12 weeks, with active osteoclasts visible.

Clinical Results
Data from 406 clinical cases over 10 years show high satisfaction with ARCA BONE, with no immunological or infectious reactions. Successful applications include:

Fractures (simple and complex)
Post-surgical filling after osteosynthesis removal
Non-union, arthrodesis, osteotomies
Prosthesis revision and spinal fusion

Implantation Guidelines
ARCA BONE should be implanted in a refreshed spongy bone site, impregnated with blood or autologous bone, ensuring complete filling and coverage. It should not bear mechanical stress without osteosynthesis.

Advantages

Synthetic origin eliminates infection risk.
Bioresorbable and biocompatible.
Excellent osteoconductive properties.

Presentation
Available in various shapes (granules, blocks, cylinders, wedges, tapers), ARCA BONE is sterilized by gamma rays and packaged for single use.

UN COMBLEMENT OSSEUX SÛR ET EFFIC ACE Les nombreux travaux et publications réalisés sur I'hydroxyapatite (HA) et Ie β β phosphate tricalciqueβ (βTCP) témoignent de l'intérêt porté à ces matériaux. Ils ont longtemps été les seuls phosphates de calcium expérimentés in vivo et implantés dans Ie corps humain. Leur composition chimique voisine de celle de I'os, favorise une biocompatibilité et une ostéointégration optimale. L’utilisation de céramiques poreuses biphasées (HA/TCP), à pores interconnectés en tant que greffe osseuse synthétique est une solution sûre et efficace au problème de la réparation...

The great number of studies and papers published on both HA (hydroxyapatite) and (PTCP) tricalcium phosphate show if need be the interest of such materials. For a long time these were the only calcium phosphates tested in vivo and implanted in humans. Their chemical composition close to that of bone favours biocompatibility and induces optimal osteo-integration. The use of such interconnected porous biphasic ceramics (HA/TCP), as synthetic bone graft substitutes is one of the answers to safe and efficient repair of bone defects and for bone grafting.
