Knee poster takes overall prize in 2007 poster presentation
By G. Jake Jaquet
A poster demonstrating that administering preoperative antibiotics to patients who have positive preoperative joint aspirate does not decrease intraoperative culture was the overall winner among the more than 550 poster presentations at this year’s AAOS Annual Meeting.
Poster P123, “Do preoperative antibiotics decrease intraoperative culture yield?” also won in the knee category. The study of 171 total knee arthroplasty patients diagnosed with periprosthethic infection found that administering preoperative antibiotics to patients did not seem to interfere with the isolation of the infecting organism from intraoperative culture samples.
The poster was submitted by Elie Ghanem, MD, of Philadelphia; Jesse Richman, BS; Robert L. Barrack, MD, St. Louis; and Javad Parvizi, MD; James J. Purtill, MD; and Peter F. Sharkey, MD, all of Philadelphia.
In addition to the overall winner, the Poster Committee named a winning poster in each category.
Poster P093, “Effects of acetabular component position on cup wear rates in total hip arthroplasty,” showed that medialization and superior positioning of the cup near 40 degrees results in less wear over compulsive maintenance of the center of rotation. The poster was submitted by Lawrence D. Dorr, MD, and Zhinian Wan, MD, both of Inglewood, Calif., and Myriam Boutary of Burbank, Calif.
Foot and Ankle
Poster P206, “Subtalar arthrodesis using interpositional fresh-frozen structural allograft,” detailed a prospective study analyzing the use of interpositional structural allograft in subtalar distraction bone-block arthrodesis. The poster was submitted by David N. Garras and Mark E. Easley, MD, both of Durham, N.C.; James R. Santangelo, MD, of Fayetteville, N.C.; and David William Wang, MD, of Durham, N.C.
Hand and Wrist
Poster P241, “Long-term outcomes of dorsal intercarpal ligament capsulodesis for chronic scapholunate dissociation,” explained that dorsal intercarpal ligament capsulodesis does not appear to prevent development of a scapholunate advanced collapse wrist pattern in long-term follow-up; treatment of chronic dorsal intercalated segment instability remains an unsolved problem. The poster was submitted by Varun K. Gajendran, MS, of Roseville, Calif.; Brett Peterson, MD, of Loomis, Calif.; and Robert Morris Szabo of Sacramento, Calif.
Poster P251, “Ultrasonographic predictors of Pavlik harness failure in Ortolani positive hips,” examined two new ultrasonographic measurements that accurately predict whether the Pavlik treatment will be successful in treating an Ortolani positive hip in infancy. The poster was submitted by Klane White, MD, of Seattle; Daniel J. Sucato, MD, of Dallas; and Sundeep Agrawal, BA.
Poster P265, “The use of multimedia to improve patient consent for knee arthroscopy,” detailed how integration of a multimedia software program into the surgical consent process can improve overall patient recall of preoperative information following knee arthroscopy. The poster was submitted by Richard De Steiger, MD, of Victoria, Australia; Andrew D. Beischer, MD, and Martin Richardson, MD, both of Melbourne, Australia; Leo Donnan, MD, of Flemington, Australia; Andrei Cornoiu, MBBS, MD, of East Doncaster, Australia; and Damian Claydon-Platt, MBBS.
Poster P283, “Patient motivation criteria and gait orthosis use in young patients with complete thoracic paraplegia,” showed how initiation of very strict criteria for prescription of gait orthoses did not affect orthotic prescription rate, or likelihood of long term or household use in complete thoracic paraplegics. The poster was submitted by Joel A. Lerman, MD, and Craig M. Mcdonald, MD, both of Sacramento, Calif., and R. Ted Abresch, MS.
Shoulder and Elbow
Two closely related posters in the shoulder and elbow category were recognized as winners. Poster P328, “Anatomical investigation of the supraspinatus insertion,” examined in detail the anatomy of the supraspinatus muscle. The poster was submitted by Kazuhiko Maeda, MD; Hiroyuki Sugaya, MD; Ryuzo Arai, MD; Joji Moriishi, MD; Mari Uomizu, MD, and Keiichi Akita, MD, all of Chiba, Japan.
Poster P326, “The infraspinatus is the most affected tendon in rotator cuff tears,” presented a detailed anatomical examination of the infraspinatus muscle. The poster was submitted by: Keisuke Matsuki, MD; Hiroyuki Sugaya, MD; Mari Uomizu, MD; Tomoyuki Mochizuki, MD; Kazuhiko Maeda, MD; Joji Moriishi, MD, and Keiichi Akita, MD, all of Chiba, Japan.
Poster P381, “A comparison of three face pillows while in the prone position for spinal surgery,” examined a study that measured and compared the tissue-pillow interface pressures on each of three different facial pillows. The poster was submitted by Margaret K. Grisell, MD; Margaret Grisell, MD; and Howard M. Place, MD, all of St. Louis.
Poster P399, “Pain management following shoulder arthroscopy: Interscalene regional blockade versus infusion pump,” reported that interscalene regional blockade more effectively reduced early postoperative pain following shoulder arthroscopy than infusion pumps and that pumps had little influence on pain once the blocks wore off. The poster was submitted by William J. Ciccone II, MD; Terri Busey, BA; David Weinstein, MD; David L. Walden, MD; Amanda Gentner, BA, and John J. Elias, PhD, all of Colorado Springs, Colo.
Poster P474, “Evaluating neutrophil priming using reamer/irrigator/aspirator vs. standard reamer in femur fractures,” presented preliminary results that suggest the reamer/irrigator/aspirator system does not attenuate neutrophil priming in a unilateral femur fracture model, but that time may be a critical factor. The poster was submitted by Steven J. Morgan, MD; Anad A. Parekh, MRCS; Wade Russel Smith, MD; Allison E. Williams, MD, and Juan Fernando Agudelo, MD, all of Denver; Ruth Grosskreuz, MD; Philip C. Eckels, BA, and Ernest Moore, MD, of Richlands, Va.
Poster P522, “Long-term results of endoprosthetic reconstruction after segmental bone resection for bone tumors,” presented an evaluation of long-term survival and patters of complications after endoprosthetic reconstruction for bone tumors through an analysis of all procedures performed over a 22-year period at a single institution. The poster was submitted by Martin M. Malawer, MD; Chia-Chun Wu; Hart Squires, MS; Robert Mikael Henshaw, MD; and Daria Brooks Terrell, MD, all of Washington, D.C.; and Ahmad Mohammad Shehadeh, MD, of Amman, Jordon.
