BellaSeno GmbH has introduced {that a} workforce at Hannover Medical College, Clinic for Trauma Surgical procedure, led by Prof. Dr. med. Philipp Mommsen, efficiently used a personalized, resorbable bone alternative scaffold utilizing 3D printing. The scaffold was used to reconstruct a 14cm segmental bone defect of the radial shaft after a 3rd diploma open contaminated fracture as a consequence of a gunshot harm.
BellaSeno is an ISO 13485-certified medtech firm growing resorbable scaffolds utilizing 3D printing.
Previous to remedy at Hannover Medical College, the affected person had undergone eleven surgical procedures with tender tissue and bony debridement to acquire secondary wound closure, whereas the radial fracture was solely stabilised by a hoop fixator.
Folllowing six additional operations and systemic antibiotic to realize bacterial eradication of the surgical area, bone reconstructive surgical procedure was carried out at Hannover Medical College utilizing BellaSeno’s resorbable scaffold along with an autologous bone graft from the medullary cavity of the femoral bone.
The scaffold is predicated on Resomer, a biodegradable polymer platform developed by Evonik. The surgical procedure succeeded and after three months, the affected person confirmed well timed bony integration and had enough elbow perform with none indicators of wound therapeutic dysfunction in response to the corporate. BellaSeno additionally says that no extra scientific indicators of an infection have been obvious.

The scaffold was designed by BellaSeno as a personalized cage to match the affected person’s anatomy and guarantee a safe maintain of autologous bone graft (RIA materials) within the massive void.
To allow correct inside vascularisation by the positioning of an arteriovenous loop or a central vascular pedicle throughout reconstructive surgical procedure, sure design options have been included to permit the position of such a fragile construction contained in the scaffold.
“As the instance of the 46-year-old sufferers demonstrates, refined options to deal with massive bone defects are scarce. BellaSeno’s scaffold enabled us to conduct a brand new surgical approach for graft vascularisation by embedding a vascular muscle arcade instantly right into a patient-specific, 3D printed bioresorbable scaffold,” stated Prof. Dr. med. Philipp Mommsen, Managing Senior Doctor, Clinic for Trauma Surgical procedure at Hannover Medical College and lead writer of the paper.
Dr. Mohit Chhaya, CEO of BellaSeno stated: “This case research as soon as once more underlines the flexibility of our know-how. Nearly any design request by a medical workforce could be fulfilled to optimise the affected person’s remedy. The open construction of the scaffold permits vascularisation which is essential not just for correct bone therapeutic but additionally to permit entry of immune cells and anti-microbial medicine to forestall surgical website infections. We’re at the moment engaged on next-generation bone scaffolds made from a composite of PCL and bio-active glass with anti-infective properties.”
