The use of standing radiographs to determine correction angles for high tibial osteotomy is not appropriate because the relative angle of the articular surfaces (condylar-plateau angle) in the weight-bearing knee changes after the osteotomy. This may give unpredictable results postoperatively. We found that the condylar-plateau angle in postoperative(More)
BACKGROUND Uncemented fixation of components in joint arthroplasty is achieved primarily through de novo bone formation at the bone-implant interface and establishment of a biological and mechanical interlock. In order to enhance bone-implant integration osteoconductive coatings and the methods of application thereof are continuously being developed and(More)
We have previously developed a radiographic technique, the oblique posterior condylar view, for assessment of the posterior aspect of the femoral condyles after total knee arthroplasty. The purpose of this study was to confirm the validity of this radiographic view based upon intra-operative findings at revision total knee arthroplasty. Lateral and oblique(More)
OBJECTIVE PATIENTs with secondary hyperparathyroidism caused by chronic kidney disease (CKD) develop secondary osteoporosis, which increases fracture risk. We report a case of insufficiency fractures complicated by secondary osteoporosis caused by chronic renal failure and gastrectomy. PATIENT A 78-year-old man with a medical history of nephrotic syndrome(More)
