Revision hip arthroplasty for excessive bone loss because of osteolysis or infection is difficult theme. Bone grafting is essential technique for bone loss and need of allograft is increasing. Recently, many hospital bone banks are established in Japan. The aim of this study is investigate efficacy and safety of allograft in our hospital bone bank. We evaluated management, result and complication of allografts retrieved from living donors in our institute.Background
Material and method
The patients with hip fracture have a general complication including heart disease. The heart echo is useful for the preoperative evaluation of cardiac function. The purpose of this study was to assess the relationship between echocardiographic findings and postoperative walking ability of patients with hip fracture.Introduction
Objectives
The cement mantle thickness for cemented stem during total hip arthroplasty (THA) is different between the complete cement mantle technique and the line-to-line technique. In the line-to-line technique, the size of the rasp is same as that of the stem. We performed THA in321 hipsof 289 patientsusing a new designed triple-tapered polished cemented stem. We investigated the short-term result of these 321 hips clinically and radiographically. From February 2002 to December 2012, 321 THAs were performed in 289 patients with the use oftriple-tapered polished cemented stem (Trilliance). Of these, 306 hips in 274 patients who were followed over 6 months, were evaluated. All THAs were undergone with direct anterior approach in supine position. The third generation cementing technique was standardized. The mean age at surgery was 65.3 years and the mean follow-up period was 24.6 months. Clinical results were evaluated by Japanese Orthopaedic Association (JOA) hip score. Intra-postoperative complications were investigated. Radiographic examinations were performed to investigate the findings of stem loosening, stress shielding, radiolucent line, osteolysis, stem subsidence, stem alignmentand cementing grade on plain radiograph.Introduction
Materials and Methods
The purpose of the present study was to describe the long-term results of THA for ONFH in patients with SLE. From 1994–2001, 18 cementless THAs (14 SLE patients) were included in the present study. Four hips (3 patients) were lost to follow-up. The remaining 14 hips (11 patients) were available for evaluation. The mean follow-up period was 13.1(range, 10.0–16.4) years. The follow-up rate was 77.8%. The mean age at the time of surgery was 35.2 (range, 27.4–51.0) years.Objectives
