OPENING DAY OF AOFAS This week the OFAC research team is traveling to San Diego for the American Orthopaedic Foot & Ankle Society (AOFAS) summer meeting. OFAC's own Greg Berlet, MD is the chairman of the meeting. This is the largest foot and ankle meeting in  the world hosting surgeons from all over the world. Dr. Thomas Lee, Dr.  Terrence Philbin, Dr. Christopher Hyer along with the OFAC Fellows will present some of OFAC's cutting edge research. In addition to all of the presentations, we will have 20 research posters on display for their peers to enjoy. Congratulations to the team for their research already recognized as a semifinalist for the 2012 Goldner Award. Their assessment of osteoprogenitor stem cells from bone marrow aspirate is one of the highest rated scientific abstract submitted to the program. The AOFAS podium presentations as follows: Successful Arthrodesis of the First Metatarsal-phalangeal Joint in Patients with Inflammatory and Non-inflammatory Arthritis:  A Comparative Analysis Authors: Shawn Morrow, DO & Christopher Hyer, DPM The purpose of this study was to compare 1st MTP fusion time and rates between patients with osteoarthritis versus Rheumatoid arthritis. The Corrective Power of the Cotton Osteotomy Authors:  Ryan Scott, DPM ,  Bradly Bussewitz, DPM, Christopher Hyer, DPM , Gregory Berlet, MD, & Terrence Philbin, DPM The cotton osteotomy is a bone cut in the medial cuneiform which helps to correct deformity in the forefoot.  This is typically done with other osteotomies in correction of flat foot. The purpose of this cadaveric study was to determine the amount of angular correction from the cotton osteotomy of the medial cuneiform using measured wedge grafts. Growth Factor Expression and Healing Time After Pulsed Electromagnetic Field Stimulation of 5thMetatarsal Nonunions: A Prospective, Randomized, Double-Blind Trial. Authors: Terrence Philbin, DO, Jaymes Granata, MD, Hsuan-Ni-Lin, Dr. J. Patrick O’Connor, & Dr. Sheldon Lin The purpose of this study was to quantify the effect of external bone stimulation on the healing of 5thmetatarsal fracture nonunions. Quantitative Assessment of Osteoprogenitor Stem Cells in Bone Marrow Aspirate from the Iliac Crest, Tibia, and Calcaneus * Authors: Christopher Hyer, DPM, Greg Berlet, MD,  Bradly Bussewitz, DPM,  Thomas Hankins, & Terrence Philbin, DO Osteoprogenitor cells obtained from bone marrow aspirate are useful in orthopedics for bone repair and treatment of nonunions.  The goal of this study was to determine which of the three locations (iliac crest, tibia, and calcaneus) yielded the highest number of osteoprogenitor cells. *Semifinalist for 2012 Goldner Award The Medial Double Arthrodesis with Lateral Column Sparing and Arthrodiastasis: A Radiographic and Chart Review Authors: Greg Berlet, MD, Christopher Hyer, DPM, Ryan Scott, DPM, Melissa Galli, DPM, & Scott Ekroth, MD This study reviewed the outcomes of a joint-sparing procedure done for patients with arthritis due to flat feet, which is performed through a less invasive approach. DAY 2 of AOFAS AOFAS is bigger and better in 2012. The meeting this year is the largest meeting in AOFAS history as well has the largest exhibit hall ever with over 70 companies participating. Today's program will feature se veral OFAC physicians speaking again. Dr. Lee is presenting a video technique of the medial double. Dr. Morrow is presenting on 1st MTP fusion in osteoarthritis and rheumatoid arthritis and Dr. Scott will present on the power of the Cotton Osteotomy. Later this afternoon Dr. Berlet will also be announcing the awards for outstanding clinical and basic research papers.
