The goal of treating artificial joint infection is to relieve the infection quickly and re-establish joint function, but many patients have underlying diseases, and treatment is often made problematic by the diversity of the causative bacteria. In this study we assessed the factor that enabled revision arthroplasty in patients with infection after artificial hip arthroplasty, including bipolar hip arthroplasty, in our hospital. The subjects were the 16 patients (16 hips) with infection after hip arthroplasty who were treated in our hospital during the past 10 years. There were 7 males and 9 females, and their mean age was 69.8 years. Primary total hip arthroplasty had been performed in 6 hips, revision hip arthroplasty in 8 hips, and bipolar hip arthroplasty in 2 hips. Infected implants were removed as soon as possible and delayed reimplantations with an interval antibiotic spacer were attempted in all patients. 9 hips were successful in reimplantation (reimplantation group) and 7 hips were impossible (No reimplantation group). In this study we investigated age, complications, body mass index (BMI), body temperature, pain, rate of resistant bacteria, number of hip surgery prior to infection and clinical manifestations compared to two groups.Introduction
Subjectives and Methods
Excellent results with use of tapered wedged cementless stem have been reported. The purpose of this study was to clarify the indication of tapered wedged cementless stems for patients with poor bone quality. Sixty-five hemiarthroplasties in 79 patients with diagnosis of femoral neck fracture were performed between February 2004 and August 2011. 14 patients were lost to follow-up after surgery, and it is 19 patients among the leaving 65 patients had the stovepipe canal. There were 2 men and 16 women, with a mean age at time of surgery 85 years (range, 75–92 years). All components were tapered wedged cementless stem (LINEAR: Encore, Kinectiv: ZIMMER). Evaluation of patient followed includes radiographic analysis (canal flare index, canal fill rate, stem alignment, bone reaction, and stem stability) and recording complication.Background
Method
Total knee arthroplasty (hereinafter TKA), it is thought that the setting position of each component and the angle have a big influence on surgical results. Preoperative planning with accurate and detailed 3D templates are has been done in many facilities in TKA. However, in the setting position, the 2D evaluation with X-rays is still common after operation, and there are few facilities going in 3D image. A three-dimensional evaluation method of the TKA includes a rating system using CT and the MRI, but influence (artifactual) with the metal occurs, and a detailed evaluation becomes difficult. In this study, we evaluated it after the matching method with the 3D plan using “Physio-Knee” where the materials of the femoral component were alumina ceramics in the preoperation of each component setting position by the CT before and after operation. We intended for 12 knees which we performed TKA used the Physio-Knee by December, 2011 from October, 2010. The all cases woman, the operation average age were 68.9 years old (62 to 79 years). For these, we performed CT photography of the whole lower limbs after operation like preoperation and each component setting was located after operation using evaluation software made in LEXI company and evaluated it.Introduction
