Burst Biologics Foot and Ankle Registry

• Conditions: Foot and Ankle Disorders; Ankle Fusion, Osteotomy

• Registration Number: NCT03077256
• Lead Sponsor: Burst Biologics

Brief Summary

This prospective registry was designed as an observational study to ascertain how commercially available Burst Products are being used by foot and ankle surgeons performing procedures which involve bone grafting, as well as determining relevant patient outcomes.

Detailed Description

Foot and ankle surgery requiring the use of bone graft is common despite recent advancements and improved outcomes with new motion preservation devices (ankle replacement). Autogenous bone remains the gold standard but is complicated by donor site morbidity and availability of a sufficient volume of graft. Over the past two decades surgeon interest in alternative bone grafts has steadily increased. Bone morphogenic proteins, synthetic bone graft substitutes, and various allograft products are widely available to surgeons. Limitations on the use of allografts in the past were mainly attributed to less than optimal donor screening and processing techniques which removed viable components needed to aid in the bone healing process.

In recent years, the focus and scientific advances in various allograft processing techniques have allowed the retention of various viable cytokines, growth factors, and cell populations which result in enhanced osteogenic and osteoinductive properties. Rigorous donor bone screening and meticulous testing has virtually eliminated the risk of disease transmission.

A unique proprietary cryoprotection processing technique for allograft tissue was developed by Smart-Surgical, Inc. and a complete line of allograft products was created and is now marketed by Burst Biologics (dba). In addition, rigorous standardized laboratory assay techniques and statistical analysis provide consistency and uniformity of the biologically active components of Burst allograft products.

This prospective registry was designed as an observational study to ascertain how commercially available Burst Products are being used by foot and ankle surgeons performing procedures which involve bone grafting, as well as determining relevant patient outcomes.
