Bellevue, Washington-based CurvaFix, Inc. has raised $10.75 million in an oversubscribed Series B round of financing led by Sectoral Asset Management.
CurvaFix Closes $10.75M in Series B and Adds to BOD

CurvaFix develops implantable medical devices to facilitate curved bone repair after fracture and injury. According to the company, it will use the proceeds to complete the RESTORE Clinical Study and initiate commercialization activities.
CurvaFix also appointed two new members to its board of directors, Michael Sjöström and Marc-André Marcotte. Both members are from Sectoral Asset Management, an investment advisor focused on global healthcare.
OTW spoke with CurvaFix Chief Executive Officer Steve Dimmer about the new funding and board members. Dimmer told OTW, “This recent influx of funding continues our momentum first originated by FDA clearance of the CurvaFix® Intramedullary Rodscrew, followed by treatment of our first patient and the addition of new members to our board of directors, most recently Mr. Sjöström and Mr. Marcotte.”
Dimmer continued, “The support from this top-tier investment syndicate will enable us to scale our U.S. commercial operations and support the RESTORE Study, a post-market physician preference study to support our commercial launch.”
In March 2019, CurvaFix received 510(k) clearance from the FDA for its CurvaFix Rodscrew. Designed to fix pelvic fractures, the CurvaFix Rodscrew is the “only device which fills the intramedullary (IM) space within the bone.”
Sjöström, senior partner of Sectoral Asset Management, explained, “This new device is designed for use in minimally invasive procedures in curved bones and may improve bone fixation and shorten surgeries.”
Sjöström continued, “We believe the CurvaFix® Rodscrew System will enable a fundamental advance in the way orthopedic patients with fractures in curved bones are treated and we look forward to supporting this team as they progress in the clinic and begin commercial activities.”

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.
