Since 1998, short stem total hip arthroplasty (THA) has been performed at the authors' institution. Currently, 30% of THAs are performed with short stems. This article reports on complications that required revision of a short stem THA. Between September 2005 and February 2012, a total of 1953 Metha short stem THAs were performed; of these, 38 required revision due to mechanical complications. ...

An outcrossed canine pedigree was developed for quantitative trait locus (QTL) mapping of hip dysplasia by breeding dysplastic Labrador retrievers to trait-free greyhounds. Measured susceptibility traits included age at onset of femoral capital chondroepiphyseal ossification (OSS), maximum hip distraction (laxity) index (DI), and the dorsolateral subluxation (DLS) score. The pedigrees consisted...

We have assessed the long-term results of 292 cemented total hip replacements which were performed for developmental dysplasia of the hip in 206 patients. The mean age of the patients at operation was 42.6 years (15.9 to 79.5) and most (202) were women. The severity of dysplasia was graded according to both the Crowe and the Hartofilakidis classifications. A 22.25-mm Charnley head was always us...

BACKGROUND Developmental dysplasia of the hip (DDH) is a condition in which bone growth irregularities subject articular cartilage to higher mechanical stresses, increase susceptibility to subluxation, and elevate the risk of early osteoarthritis. Study objectives were to calculate three-dimensional cartilage contact stresses and to examine increases of accumulated pressure exposure over a gait...

Purpose: Unfavourable distribution of contact stress over the load bearing area is considered a risk factor for early coxarthritis and it interest to outline respective biomechanical parameters its prediction. The purpose work was develop transparent mathematical model which can be used assess in hip from imaged structures pelvis proximal femora, large population studies clinical practice. Meth...

conclusions scc, lgdn, and hgdn are common associated findings and precursors of hcc in livers infected with hepatitis b. a strict follow-up and a precise and thorough sampling of livers with scc and any abnormal dysplastic nodules (dns), especially those larger than 1 cm, are highly recommended because these dns are highly associated with malignancy. results among all explanted cirrhotic liver...
