Resorbable Polymer Pin Inserted with Ultrasound Activated BoneWelding Technique Compared with a Screw for Osteotomy Fixation in the Reverse L Bunion Correction

Clin Podiatr Med Surg. 2018 Oct;35(4):373-385. doi: 10.1016/j.cpm.2018.05.001. Epub 2018 Aug 11.


Screw fixation of an osteotomy in the first metatarsal for bunion correction represents a compromise. The need to return to the operating room for removal exposes patients to added anesthesia risk, expense, time, and possible surgical complications. This article compares screw fixation with a novel new bioresorbable polymer pin that is inserted with an ultrasound activated BoneWelding technique to fixate a bunion correction using a reversed L osteotomy. This article reviews and discusses the present benefits of a time-tested osteotomy that, when fixated with this polymer and BoneWelding technique, offers new solutions for a compromised patient population.
