Background: We previously established a proof-of-concept in a human cadaveric model where conventional wire cerclage was augmented with a novel biocompatible bone adhesive that increased mechanical strength and early bone stability. We report the results of a single-center, pilot, randomized clinical trial of the effects of adhesive-enhanced closure of the sternum on functional postoperative recovery.
Methods: In 55 patients undergoing primary sternotomy, 26 patients underwent conventional wire closure and were compared with 29 patients who underwent adhesive-enhanced closure, which consisted of Kryptonite biocompatible adhesive (Doctors Research Group Inc, Southbury, CT) applied to each sternal edge in addition to conventional 7-wire cerclage.
A novel approach to enhance the mechanical stability of primary sternal closure is described. An osteoconductive bone adhesive is used to augment conventional wire cerclage. More than 30 patients have undergone primary sternal closure using Kryptonite bone adhesive.

Postoperative functional recovery, respiration, pain, sternal dehiscence, and infection are influenced by early bone stability. This translational research report provides proof-of-concept (part A) and first-in-man clinical data (part B) with use of a triglyceride-based porous adhesive to rapidly enhance the stability of conventional sternal closure.
