Projects presented in a peer reviewed forum

Investigations with both corporate partners and institutions of higher learning have been presented in forums around the country and worldwide. We have recently presented at the podium of the AAOS, AOSSM, CSRS, FAI, the hand society, ORS, OTA and numerous regional conferences. Our work has also been published in the American Journal of Sports Medicine, Arthroscopy, Clinical Orthopaedics and Related Research, Foot and Ankle International, the Journal of Bone and Joint Surgery, Journal of Hand Surgery, Journal of Knee Surgery Journal of Orthopaedic Trauma, and Spine.

Our team has technique experience with all regions of the body and devices of all origin.
