20.500.12556/RUL-113168 Biomechanical analysis of the periacetabular hip osteotomy a case report We determined biomechanical parameters (magnitude of the resultant hip force, its inclination with respect to the vertical, contact hip stress, position of the stress pole, size of the load bearing area, functional angle of the load bearing area and stress gradient index) in a single patient before and after the periacetabular osteotomy. The operation was performed due to hip dysplasia. We used two mathematical models to determine the resultant hip force in the one legged stance: the HIPSTRESS model (1) and the one-muscle model (2). Stress was calculated by using the HIPSTRESS model for contact stress (2). The geometrical parameters needed for calculation of biomechanical parameters were assessed from standard anteroposterior radiograms taken from the archive. Before operation, both hips were dysplastic according to the HIPSTRESS method criterion. We found considerable improvement of the contact stress distribution in the operated hip, however, contact hip stress became less favorable in the contralateral hip after the operation. After the operation, the operated hip became normal while at the contralateral side, the degree of the dysplasia has increased. biomechanical parameters hip osteotomy periacetabular osteotomy hip dysplasia mathematical models hip force true false false Angleški jezik Angleški jezik Neznano 2019-12-09 14:18:04 2019-12-09 14:18:04 2022-08-25 03:55:06 0000-00-00 00:00:00 2019 0 0 Str. 38-47 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577.3:[616-089:617.581] 5744235 302959104 RAZ_Suligoj_Ariana_2019.pdf RAZ_Suligoj_Ariana_2019.pdf 1 4D8125BB25BA277ECB57283330A323D6 7c2de782a876571b39672bae3ee0e27979fc3cc561ebf33654f59ccaad54766c 09ee923f-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125205 Zdravstvena fakulteta 0 0 0
