Inter and intra-observer errors for postoperative total hip radiographic assessment using computer aided design

Plain radiographic assessment of primary total hip arthroplasty following surgery remains to be the commonest radiological assessment. The current paper, studies accuracy and concordance between observers reviewing these radiographs. A prospective medical note review ten patients who underwent replacement for osteoarthritis, with a mean age 69 years. Early 6 weeks postoperative x-rays were assessed profile version using computer aided design (CAD) by two on different occasions. Orthopaedic surgeons perform hip. results analyzed statistically. Dimensions, including Femoral offset, medial offset ilioischial showed high degree inter- film intra-film correlation, inter-class correlation (ICC) over 0.8. Except measured post- operative films (p=0.067) first rater, all intra inter significantly benchmark 0.6. In terms stem alignment, cup inclination version, rater n°2 ranges from 0.574 0.975 0.6, except in case th? week follow-up ; meanwhile n°1 0.581 0.819 none inter-rater reliability inter-film dichotomy among dimensions measurement. Dimensions femo- ral substantial reliability, intra-rater/film reliability.
