An orthopedic implant device and system support the fusion of bones in the medial column of the human foot. An exemplary implant uses an improved lag screw and supplemental components, including a washer plate and transverse screws which penetrate transverse through holes in the shaft of the lag screw. Additionally, a surgical procedure is described which may employ such an implant. The improved lag screw may be inserted at the plantar surface of the first metatarsal and support the fusion of, for example, the transverse tarsal joint, the cuneonavicular joint, and the tarsometatarsal joint.
Patrick Jones, junior in VCU Biomedical Engineering, received a VCU UROP (Undergraduate Research Opportunities Program) Summer Research Fellowship award for summer 2017. His research is on automated analysis of acetabular surface features from CT scans.
Alex Smith's MS thesis, entitled "Patient Specific Computational Models to Optimize Surgical Correction for Flatfoot Deformity", was selected by VCU's Graduate School to receive the 2016-2017 ETD Master's Thesis Award. The thesis was also nominated for the Conference of Southern Graduate Schools 2017 ETD Master's Thesis Award.
Alex Smith participated in the Master's Student Competition at 2016 SB3C (Summer Biomechanics, Bioengineering & Biotransport Conference) held at the Gaylord Convention Center in National Harbor, Maryland. He received 2nd place for his thesis work entitled "Patient Specific Computational Models to Optimize Surgical Correction for Flatfoot Deformity". This work is being published by the Journal of Orthopaedic Research. Alex received his MS degree in Biomedical Engineering under Dr. Wayne.
Peter Liacouras, Ph.D., completed his doctoral degree in the VCU Orthopaedic Research Laboratory and established a career with the Walter Reed National Military Medical Center in Bethesda, Maryland. Some of his recent successes were highlighted by FoxNews. VCU shared the story on its homepage.

A Tibiotalar Arthrodesis Guide (TAG) used for fusion of the talus to the tibia is comprised of several basic components. The main component is a straight guide post upon which other components can slide. A curved arm is featured at the end of the straight guide post, featuring points at the ends which serve as indicators of the pins' exit sites based upon the lines of action of the parallel pins. The parallel guide cylinders are positioned on a movable arm which translates superiorly and inferiorly on the guide post of the handle, allowing a surgeon to adjust the device for varying ankle sizes. A “home-run” pin guide cylinder for a home-run guide pin is oriented superiorly and at an angle to the parallel guide cylinders. Using a similar concept as the parallel guide cylinders, the “home-run” guide is also attached to a movable arm that can translate inferiorly and superiorly along the main guide post. A medial guide cylinder for a medial guide pin passes through one of a plurality of holes in a vertical guide arm. The surgeon has the flexibility to utilize either the “home-run” or medial pins, depending on the needs of the patient and preference of the surgeon and, in either case, the “home-run” and medial pin pass between the two parallel pins.
