Abstract
The reliability and validity of the Hartofilakidis et al. classification system in adults with congenital hip disease (CHD) were examined. The radiographs of 102 adult patients (158 hips) with CHD were independently assessed by three senior surgeons. Interobserver variability was assessed by examining the agreement between the three raters while validity of the classification system was assessed by examining the agreement between the assessment by either one of the three raters and the intraoperative finding (reference standard). The interobserver agreement between the three observers was high ranging from 0.720 to 0.854 (substantial to excellent) while the agreement of the preoperative prediction with the intraoperative findings was 87.4% (K = 0.823, excellent agreement). The Hartofilakidis et al. classification system reliably predicts from preoperative pelvis radiographs the bone deficiencies encountered during the operation.
Résumé
Nous avons voulu tester dans ce travail la fiabilité et la viabilité de la classification d’Hartofilakidis dans les séquelles des affections congénitales de la hanche. Les radios de 102 adultes (158 hanches) avec lésions congénitales ont été analysées, de façon indépendante par trois chirurgiens seniors avec validation inter observateur et intra observateur. Les résultats de cette analyse inter observateur sont hautement significatifs de 0.720 à 0.854 et les prévisions pré opératoires confirmées par les constatations per opératoires sont excellentes 87.4% (k = 0.823). La classification d’Hartofilakidis est un système parfaitement viable qui permet de prévoir un pré opératoire les lésions que l’on pourra constater en per opératoire.
