Historically, the first implant designed that had expanding capabilities (no distal locking bolts) was the Biomet Brooker-Wills Nail. For those of our readers that are not aware, EO is not the first Israeli Company that offered the industry expanding locking capabilities. Disc-O-Tech (now defunct, sold their IP to Kyphon) was the first Israeli Company that brought an expanding humeral, tibial and femoral nail to our market. They attempted to use surgeon consultants from The Hospital for Special Surgery in New York City to no avail. So why do we need an expanding pedicle screw?
I suppose the argument will be made that this will benefit the surgeon when treating a patient with osteopenic bone. Yet, TSB must ask; based on the current state-of-the art, are surgeons having trouble with pedicle screw that don't expand? I think not! TSB believes that most of the people involved with EO are probably very nice people, but the question must be asked, why now? For those investors that infused capital into this venture, if your money was burning a whole in your pocket you can always make a charitable contribution to TSB. What do our readers believe, what do our readers think?
