COLLAPAT®II

Collagen medical device containing hydroxyapatite used as bone substitute in orthopaedics, spine surgery and in maxillo facial surgery and odonto-stomatology.

COLLAPAT® II is a bone void filler presented in a sponge form.
It is composed of a collagen structure in which ceramised hydroxyapatite granules are dispersed. The granules of hydroxyapatite give the material its osteoconductive properties. The hydroxyapatite is slowly resorbed.
As a collagen medical device, COLLAPAT® II its strong haemostatic power and is completely resorbable in a few weeks. The collagen type I is extracted from bovine dermis. The manufacturing procedure comprises stages recognized to inactivate viruses and non-conventional transmissible agents such as Prions. 

These treatments make it possible to ensure maximum microbiological safety for COLLAPAT® II as a bone void filler or bone substitute, in particular in respect to the agent responsible for BSE.

Properties

– COLLAPAT® II bone void filler is osteoconductive. It is generally completely colonised by the healthy orthotopic tissue thanks to intensive bone regeneration.

– COLLAPAT® II
bone void filler exerts a haemostatic effect on the bone surfaces that it covers and on the muscles that are partially freed and replaced during surgery, stopping bleeding in a few minutes.

– COLLAPAT® II bone void filler is ready to use and easy to handle, to mold and to trim.

– COLLAPAT® II bone void filler is hydrophilic: the matrix takes the consistency of a paste in contact with blood or tissue fluids.

– COLLAPAT® II bone void filler perfectly fits to the anatomic area.

Indications

[

After extracting cortico-spongoid bone fragments

[

After tumour resection

[

In revision prosthesis

[

In surgical spondylodeses

[

In cases of pseudarthrosis

[

In certain fractures treated by osteosynthesis

COLLAPAT® II as a bone substitute is also used to induce bone substance replacement in maxillo facial surgery and
odonto-stomatology:

[

After removal of radicular or dental cysts

[

Periodontal pocket debridement

[

Filling for a sinus grafts

[

Restoration of bone stock following avulsion, trauma or tumours prior to fitting of implants

Examples of use

Specific use are referred in our clinical data

Spinal surgery:
• In cervical surgery: alone inside cervical fusion cage.
• In lumbar surgery: mixed with autograft and in contact with osteosynthesis material.

Foot surgery:
in the treatment of Hallux valgus: to fill the defect created by the osteotomy, then to fill the defect after the removal of the screws.

Knee and Hip:
in total prosthesis, between the sharpened bone and the prosthesis.

Knee in ligamentoplasty:
to fill the bone graft harvesting sites and the entry to the tibial tunnel.

Method of administration

COLLAPAT® II bone void filler must be used in perfectly sterile operating conditions after adequate preparation of the site to be treated.
COLLAPAT® II bone void filler can be cut, using surgical scissors, to the desired dimensions to facilitate its application. After being wet with tissue fluids, antibiotics or saline solution, COLLAPAT® II bone void filler becomes soft and paste-like, making it easy to use to fill the cavity requiring treatment.
Draining is strongly recommended but the drains must not be in direct contact with COLLAPAT® II.
Rinsing of the implanted area is to be avoided.
COLLAPAT® II bone void filler is not designed to be removed except in the case of post-surgical infection.
In the case of widespread and very deep bone lesions or segment defects of more than 1 to 2 cm, autologous bone shavings or PRP (Platelet Rich Plasma) should be combined with COLLAPAT® II bone void filler.
Bone instabilities require supporting osteosynthesis.
