BellaSeno 3D prints resorbable bone scaffold for Hannover Medical School

A staff on the Hannover Medical College, Clinic for Trauma Surgical procedure has efficiently used a personalized, resorbable bone alternative scaffold produced by BellaSeno, an ISO 13485-certified medtech firm creating resorbable scaffolds utilizing additive manufacturing applied sciences, to reconstruct a 14cm segmental bone defect of the radial shaft after third-degree open contaminated fracture as a consequence of a traumatic gunshot harm.

Earlier than his remedy at Hannover Medical College, the affected person had undergone eleven surgical procedures with smooth tissue and bony debridement to acquire secondary wound closure, whereas the radial fracture was solely stabilized by a hoop fixator. Following six additional operations and systemic antibiotic remedy to attain bacterial eradication of the surgical area, bone reconstructive surgical procedure was carried out at Hannover Medical College utilizing BellaSeno’s resorbable scaffold together 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 satisfactory elbow operate with none indicators of wound therapeutic dysfunction. Additionally, no extra medical indicators of an infection had been obvious. The case research was revealed on this month’s Journal of Customized Drugs.

The scaffold was designed by BellaSeno as a personalized cage to completely match the affected person’s anatomy and to make sure a safe maintain of autologous bone graft (RIA materials) within the massive void. To allow correct inside vascularization by the positioning of an arterio-venous loop, or a central vascular pedicle, throughout reconstructive surgical procedure, sure design options had been included to permit the location of such a fragile construction contained in the scaffold. The scaffold was manufactured by BellaSeno’s proprietary AI-driven AM amenities – primarily based on the so-called no-touch strategy. The cage, consisting of an internal and outer help body with a primary and a locking half, is constituted of utterly bioresorbable, high-quality, GMP-grade Resomer polycaprolactone (mPCL) and supplies osteoconductive properties. Throughout surgical procedure, the staff determined to make use of a vascular pedicle to make sure fast inside vascularization, which was positioned and stuck by an aperture positioned on the outer cage body. The process was carried out in October 2023.

“As the instance of the 46-year-old affected person demonstrates, refined options to deal with massive bone defects are scarce. BellaSeno’s scaffold enabled us to conduct a brand new surgical method for graft vascularization by embedding a vascular muscle arcade straight right into a patient-specific, 3D printed bioresorbable scaffold,” mentioned Prof. Dr. med. Philipp Mommsen, Managing Senior Doctor on the Clinic for Trauma Surgical procedure at Hannover Medical College, and lead creator of the paper. “This surgical process represents an progressive and promising strategy for the restoration of intensive bone defects. As we see an rising variety of such catastrophic and really difficult-to-treat defects we face a quickly rising medical must reconstruct such accidents.”

“The sheer dimension of such defects and the dearth of vascularization have restricted the optimum remedy of large-volume bone defects,” mentioned Priv. Doz. Dr. med. Tobias Grossner, CMO of BellaSeno. “Utilizing considered one of our scaffolds, the excellent staff at Hannover Medical College was capable of carry out the reconstruction of such an intensive radial shaft bone whereas making certain fast vascularization. This demonstrates the facility of our know-how to enhance the surgical remedy of enormous bone defects, individually personalized to the precise anatomy of the affected person and the design preferences of the surgeon.”

“This case research as soon as once more underlines the flexibility of our know-how,” mentioned Dr. Mohit Chhaya, CEO of BellaSeno. “Virtually any design request by a medical staff might be fulfilled to optimize the affected person’s remedy. The open construction of the scaffold permits vascularization which is essential not just for correct bone therapeutic but in addition to permit entry of immune cells and anti-microbial medicine to stop surgical web site 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.”

BellaSeno’s MDR-certified manufacturing platform is designed to satisfy the necessities of medical scaffolds starting from smooth tissue to bone and permits the manufacturing of each custom-made and off-the-shelf sterile medical implants.
