  • Primerjava biomehanskega statusa displastičnih in zdravih kolkov = Comparison of the biomechanical status in dysplastic and healthy hips
    Mavčič, Blaž
    Hip dysplasia may in the long term result in joint cartilage degeneration and ostheoarthrosis development. Clinical, radiographic, but also biomechanical assessment are important in the examination ... of dysplastic hips, the most important biomechanical parameter in evaluation of the hip status being the maximal stress that develops in the weight bearing surface of the hip. The aimof our work was to evaluate whether dysplastic hips have higher maximal stress values than normal healthy hips. The purpose of our work was also to elucidate which biomechanical parameters differ significantly in dysplastic and healthy hips. The research group consisted of 56 dysplastic hips from the Department of Orthopaedic Surgery in Ljubljana. The control group consisted of60 hips of patients from Department of Traumatology in Ljubljana operated upon due to trauma of the femoral neck (we only examined the healthy, undamaged hips). Contours of antero-posterior rentgenograms of the selected patients were made and then transformed into digital form which enabled further automatic computerized calculation of hip stresses and other biomechanical parameters. Results have shown that the maximal hip stress attains significantly higher values in dysplastic hips (median = 4.36 kPa/N) than in normal healthy hips (median = 1.72 kPa/N). The difference is statistically significant (P < 0.0001). This is mostly due to the considerablyand statistically significantly reduced Wiberg angle and due to considerably and statistically significantly reduced hip-resultant-force inclination. Maximal hip stress in the hip weight bearing area attains importantly higher values in dysplastic hips than in healthy hips and could therefore serve as an important parameter in hip dysplasia evaluation.
