Streamlined single use instruments for simplified hip, knee*, shoulder* and trauma* orthopedic surgery to improve the logistical and economic efficiency of public and private hospitals through an innovative and responsible approach.

Founded by three partners with complementary backgrounds, OSTIUM Group ® S.A.S. is a Medtech start-up that aims to develop and market a range of innovative single-use surgical instruments called Cillar®. This range of instruments will initially be dedicated to Total Hip Replacement (THR), an approach based on the current economic model of the Social Security reimbursement rate. Cillar® instrumentation can be associated with different types of implants and will be fully recycled after its use.

With this innovative concept, we want to help improve the quality of life of our fellow citizens while minimizing the environmental impact of health procedures.

Established since its creation in the heart of the Nantes metropolis, OSTIUM Group® S.A.S. promotes and relies on the strength and know-how of numerous academic and industrial partners in France and in Europe. Currently with 8 employees in the areas of R&D and Regulatory Affairs and Quality Assurance, we support leading orthopedic companies in their single-use surgical instrumentation innovation projects.

A word from the President

After many years of development, this project is now mature and in the ideal “time to market”. It is supported by a multidisciplinary team that is complementary in terms of its entrepreneurial approach as well as its culture and experience in the health sector.

OSTIUM Group® S.A.S. was born out of our desire to help companies selling orthopedic implants to free themselves from the constraints of heavy and costly management of their instrumentation, and to enable health establishments to optimize their internal logistics and reinforce patient safety by offering them an attractive and virtuous solution from an economic, organizational and environmental point of view.

It is an ambitious project combining these three inseparable building blocks. These form a logical whole that naturally meets the expectations of the various market stakeholders.

We are convinced that once proven for total hip replacement, our innovative solution can be extended to many other surgeries, thus helping to refocus healthcare professionals ever closer to the patient.
Finally, our commitment is based on our desire to support the transformation of healthcare establishments towards a model that is increasingly efficient in the care and treatment of patients, and more economical in its operation and more ambitious in its approach to environmental responsibilities.
