Jonathan Isenburg Joins Conventus Orthopaedics

“Isenburg brings corporate finance and executive experience to Conventus spanning both entrepreneurial and public company settings. Since April 2015, Mr. Isenburg served as CFO at Infraredx, Inc., where he led the cardiovascular imaging start-up through a dual-track IPO and M&A process that culminated in a sale to a strategic buyer.”
“I am pleased to welcome Jonathan to the Conventus team. We will benefit from his expertise and leadership as we continue to grow commercial operations and accelerate development to bring the CAGE platform technology to additional types of fractures,” said Matthew Jewett, Conventus CEO.
“Jonathan is an experienced medical device industry executive who has excelled in corporate finance, strategy, business development and operations. He has a proven track record of success and we look forward to utilizing his many talents.”
“Prior to his most recent role as CFO of Infraredx, Inc., Isenburg served as a manager in Financial Advisory Services at RSM from 2008 to 2013. Isenburg was a CPA who began his career as an auditor at PricewaterhouseCoopers. He earned his bachelor’s degree in Accounting from the University of Massachusetts—Amherst and a graduate degree in finance from Boston University.”
Isenburg told OTW, “I am thrilled to join a talented Conventus organization. We have the right investors, leadership, and employees to dramatically improve upon existing surgical and conservative treatment outcomes in proximal humerus repair. We will also use our revolutionary fracture repair technology and methods to help patients heal from other types of traumatic fractures. I am personally looking forward to the challenges and rewards of building this company to help patients. I am grateful for the opportunity to join Conventus as its CFO.”
“I joined Conventus after five wonderful years at Infraredx. I joined Infraredx in 2013 to prepare it for an IPO [initial public offering] attempt as it was just beginning to commercialize in the United States and Japan. The finance team and I prepared the company for an IPO; however, the CEO, Jason Bottiglieri, and I sold Infraredx to the Nipro Corporation of Japan in late 2015. Infraredx provided me with the opportunity to transition out of financial consulting roles at the national firm RSM and into the life sciences industry. While at Infraredx, I acquired deep meaningful experience in fund raising, strategic planning, investor relations, and international business. I look forward to drawing upon those experiences at Conventus.”
“In the next year, I will work with Conventus leadership to identify and refine those developmental milestones that will enable us to demonstrate the value of our solution for patients and surgeons. With increased usage and strong outcomes data, the CEO, Matt Jewett, and I will raise the finance necessary to catalyze the revolution in fracture repair that is only possible with the Conventus CAGE.”

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
