We present a new CT-based method which measures cover of the femoral head in both normal and dysplastic hips and allows assessment of acetabular inclination and anteversion. A clear topographical image of the head with its covered area is generated. We studied 36 normal and 39 dysplastic hips. In the normal hips the mean cover was 73% (66% to 81%), whereas in the dysplastic group it was 51% (38...

hip arthroplasty for primary osteoarthrosis in younger patients in the Finnish Ar-throplasty Register – 4661 primary replacements followed for 0-22 years.cemented total hip arthroplasty in young patients – a mid-to long-term follow-up study from the Finnish Arthroplasty Register. Total hip arthro-plasty for rheumatoid arthritis in younger patients. 2557 replacements in the Finnish Arthroplasty ...

background: the prevalence of hip dysplasia is 1 in 1000. several pelvic osteotomy methods have been developed to prevent early osteoarthritis, such as triple osteotomy. in this study we are going to introduce our new technique that was done on 4 patients with favorable short-term results.   methods: four patients underwent triple osteotomy and fixation using a reconstruction plate and early we...

By using a mathematical model of the adult human hip in the static one-legged stance position of the body, the forces acting on the hip, peak stress in the hip joint and other relevant radiographic and biomechanical parameters were assessed. The aims were to examine if the peak stress in dysplastic hips is higher than in normal hips and to find out which biomechanical parameters contribute sign...

PURPOSE Hip arthroscopy is a well established therapeutic intervention for an increasing number of painful hip conditions. Developmental dysplasia of the hip (DDH) is commonly associated with intra-articular hip pathology. However, some surgeons perceive patients with hip dysplasia as poor candidates for hip arthroscopy. Our aim was to describe early outcomes of arthroscopic treatment for patie...

Hip dysplasia and hip joint deformities in general are recognized as possible precursors of osteoarthritic development. Early and correct identification of hip dysplasia is important in order to offer timely joint preserving treatment. In the contemporary literature, several controversies exist, and some of these were the focus of this doctoral thesis. Categorized into subjects, the major findi...

Objectives: This retrospective study was designed to evaluate outcome of patients with coxarthrosis secondary to low grade hip dysplasia treated with large head Metal-on-Metal (MoM) hip arthroplasty. Patients and methods: Seventy–six dysplastic hips of sixty-six patients were managed with large head MoM cementless total hip arthroplasty and they had a mean of 51 months (range, 42-62 months) fol...
