Design and prototyping

The design and prototyping of all Groupe Lépine implants are performed in Genay, in the head office, by a competent and efficient design office.

Prototyping to validate implant manufacturing plans is also realized within the company using 3D printers.

Wrought

Groupe Lépine has its own forge based in Orthez. This ancestral technique makes it possible to obtain a metallic form by hot or cold deformation of a metal bar.

Foundry

1st stage of manufacture for implants with complex geometry, the foundry makes it possible to obtain a maximum degree of precision. Implants are obtained by casting the selected alloy into silica molds. This is the only manufacturing process carried out abroad, in the German subsidiary located in Stade.

Machining

Incorporated at the Genay production site, machining is a family of chip removal machining techniques.The machining is intended to give the implant its final shape.

Coating

In order to improve the osseointegration of certain implants, their surface is coated with hydroxyapatite.This is injected as a powder in a gas heated to high temperature and projected onto the part to be coated.

Ceramic

Some heads and some inserts are made of ceramic. Their formatting requires a special technique mastered by our factory Genay. The main material composed of different alumina oxides is compacted and shaped by dry pressing

Mechanical and clinical validation

All implants designed by lépine group meet the standards of mechanical validations and are often tested beyond these mandatory requirements. The company has chosen to internalize all of these validation protocols.A Regulatory Affairs team is in charge of the

splints

The Lépine Soft splints have been developed for more than 25 years in our Lyon and Roanne workshops. They combine orthopedic requirements, industry professions and the technical expertise of the industry in order to guarantee to its customers an optimal quality of each of the Lépine Soft CE mark certified splints.

Tissue bank

TBF Tissue and Cell Bank ISO 9001 certified, offers a complete range of bone substitutes to meet the clinical needs of orthopedic, spine, neurosurgery or trauma surgeons. The use of bone marrow grafts of human origin, mineralized and spongy, from living donors, treated by a highly secure and proven process, offers an ideal solution for bone reconstruction.

Plastics

ICB, Groupe Lépine's industrial subsidiary located on the Genay site, specializes in the injection of medical polymers. This process allows mass production of single-use ancillaries and resorbable implants.

Shape memory alloy

In 1998, Groupe Lépine decided to internalize the manufacturing of its osteosynthesis staples as well as its Kirschner pins by creating AMF (Alliage à Mémoire de Forme), one of its first industrial subsidiaries located in Lury sur Arnon, France.The company, which now has 15 employees, has also become, over time, a platform for manufacturing prototypes and mechanical tests for the Group.
