Convened under the auspicious of esteemed endorsers - ISTA

ecovery of chief complaints such as low back pain, knee pain or contralateral hip pain.However, there were few reports of conversion focusing on the chief complaints. The purposeof this study was to evaluate the results of total hip arthroplasties (THAs) with arthrodesed hips.Material and Methods: Between February 2004 and July 2009, fifteen arthrodesed hips wereconverted to THAs in 15 patients with a mean follow-up of 3.2 years (0.4 to 5). There were 10women and 5 men with a mean age of 62.2 years (46 to 84) at the time of the operation. Themean duration of arthrodesis before conversion was 34.5 years (3 to 78). Initial diagnosis wastuberculosis in 7 hips, developmental dysplasia in 3 hips, ankylosing spondylitis in 2 hips,sepsis in 2 hips and aseptic necrosis in 1 hip. Before surgery, 10 hips (67%) had a surgicalfusion and 5 hips (33%) had a spontaneous fusion. The operation was carried out with thepatient in the lateral decubitus position using Dall’s transgluteal approach, and all patientsreceived cemented THAs. The hips were assessed clinically and radiologically before surgery,at 3 months, 6 months and yearly after THA, retrospectively. No patients were lost to followup.Results: The mean Japanese Orthopaedic Association hip score improved from a mean of 49.1(24 to 71) to a mean of 74.2 (40 to 89) at the final follow-up. In particular, the result ofconversion in a spontaneous fusion was better than in a surgical fusion. Relief of low back pain(10 patients), knee pain (9 patients) or contralateral hip pain (4 patients) was evident in allpatients. No radiolucent lines or evident loosening at the most recent follow-up was seen. Postoperativecomplication included 1 recurrent dislocation requiring revision.Conclusions: The outcome after conversion of arthrodesis to THA was favorable. However, theindication of conversion should be selected carefully because of preoperative poor function andpostoperative long management.Poster: 113Total Joint Arthroplasty for QuantiFERON Positive PatientsTakuma Yagura - Kansai Medical University - Osaka, Japan*Kenichi Oe - - ,Tomohisa Nakamura - Kansai Medical University - Hirakata, JapanHiroshi Ohno - Kansai Medical University - Hirakata, JapanTakahiko Wada - Kansai Medical University - Hirakata, JapanHirokazu Iida - Kansai Medical University - Hirakata, Japan*Email: enichi.1972@k7.dion.ne.jpBackground: Joint tuberculosis (TB) is one of the disorders that we have to keep in our hearts.It is well known that QuantiFERON-TB Gold (QFT-G, Cellestis Limited, Australia) is commonmethod for the diagnosis of TB. However, there is no guideline of the orthpaedic treatment forQFT-G positive cases. Here we report that the successful treatment of five cases who wereperformed total joint arthroplasty (TJA) in QFT-G positive.Material and Methods: Between August 2009 and February 2010, five TJAs were performedfile:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
