Three exhibits win Awards of Excellence

Scientific Exhibits graphically illustrate a study or complex procedure and provide opportunities for in-depth exchanges of information. Of the more than 80 Scientific Exhibits on display at the 2011 AAOS Annual Meeting, the following three have been selected by the AAOS Exhibits Committee to receive an Award of Excellence:

SE61—How to Treat Osteochondritis Dissecans of the Knee: Surgical Techniques and New Trends, by Elizaveta Kon, MD; Francesca Vannini, MD; Roberto Buda; Giuseppe Filardo, MD; Marco Cavallo, MD; Alberto Ruffilli, MD; Matteo Nanni, MD; Maurilio Marcacci, MD; and Sandro Giannini, MD

This exhibit reviews and evaluates five different techniques used to treat osteochondritis dissecans of the knee.

SE09—Revision of a Ceramic Hip for Fractured Ceramic Components, by Francesco Traina, MD; Enrico Tassinari, MD; Marcello De Fine, MD; Barbara Bordini, MD; and Aldo Toni, MD

Revising a total hip with ceramic components is a difficult procedure. This study identifies technical factors that affect the outcome and proposes a guideline for the treatment of ceramic component failures.

SE02—The High-Performance Modular Hip: Curse or Comfort? by A. Seth Greenwald, DPhil Oxon; J. David Blaha, MD; Michael Dunbar, MD, PhD; Stephen B. Murphy, MD; Joshua J. Jacobs, MD; and Christine Heim

This exhibit describes extensive clinical and laboratory comparisons that highlight features that account for the failure of modular hip arthroplasty devices.

The selected exhibits will be submitted to The Journal of Bone and Joint Surgery (JBJS) for publication later this year.

Three exhibits received “honorable mention” and will also be submitted to JBJS for possible publication. They are:

SE03—Understanding Why Metal-on-Metal Hips Fail: The London Implant Retrieval Centre by Alister Hart, FRCS; Richard Underwood, PhD; Philippa Cann, PhD; Barry Sampson, MD; Adam Mitchell, MD; Keshthra Satchithananda, FRCR; Martyn Porter, MD; Justin P. Cobb, MD; and John Skinner, FRCS

This multidisciplinary team analyzed 320 failed metal-on-metal hip arthroplasties (600 components) to better understand the mechanisms of failure.

SE08—Management of Periprosthetic Joint Infection: The Current Knowledge by Javad Parvizi, MD; Bahar Adeli, BA; Benjamin Zmistowski; Camilo Restrepo, MD; S. Mehdi Jafari, MD; Aaron Carter; and A. Seth Greenwald, DPhil Oxon

This exhibit presents prognostic classifications to predict the outcome of surgery for periprosthetic joint infection.

SE11—Gluteus Maximus Transfer for Abductor Deficiency in Total Hip Arthroplasty by Leo Whiteside, MD

Transfer of the anterior half of the gluteus maximum muscle to the greater trochanter provides functional recovery of hip abduction after the loss of the gluteus medius and minimus muscles.

Scientific Exhibits are on display in the Sales Pavilion through Saturday. The principal exhibitor or one of the coauthors will be available today from 11:30 a.m. – 12:30 p.m. to provide information and answer questions about the exhibit.
