Original Article


The aim of this study was to establish a relationship between the existence of cranial acetabular osteophytes (CAO) in hip joints showing varying degrees of degenerative alterations and the range of maximal hip abduction. Seventy-six hip joints from 38 patients (42–82 years old) expecting hip joint replacement because of primary osteoarthritis (OA) were examined; out of those, 50 hip joints showed different levels of OA according to the American College of Rheumatology criteria. The radiological evaluation included the measurement of the length of the CAO and the amplitude of “free angle” (FA, centered in the femoral head), remaining between the lateral extremity of the CAO and the point where the femoral neck would hit the CAO during abduction. The range of passive motion (ROPM) for abduction was assessed using a goniometer. The correlation between abduction and radiological alterations was calculated with the Pearson coefficient. ROPM in abduction was negatively correlated with the length of CAO (r = −0.50; P < 0.01) and positively correlated with the FA (r = 0.60; P < 0.01). The data suggest that the length of CAO plays a key role to limit the ROPM during abduction and that the length of CAO and FA may be useful measures to predict hip function during abduction.

Les ostéophytes acétabulaires crâniens limitent l’amplitude maximale de l’abduction de l’hanche


L’objectif de cette étude a été d’établir le rapport entre l’existence des ostéophytes acétabulaires crâniens (OAC) dans les articulations de la hanche avec différents degrés de dégénération articulaire et l’amplitude de l’abduction de l’articulation. Nous avons examiné soixante-seize hanches chez 38 patients (d’âge compris entre 42–82) qui attendaient une chirurgie de substitution articulaire pour ostéoarthrose (OA) primaire; 50 hanches présentaient des différents degrés de OA basés sur les critères du Collège Américain de Rhumatologie. Les évaluations radiographiques, incluaient la mesure de l’extension de l’OAC et l’amplitude de “l’angle libre” (AL, dont la verticale se trouve située dans le centre de la tête du fémur), compris entre l’extrémité latérale de l’OAC et le point où le col du fémur se trouve théoriquement en contact avec le OAC pendant l’abduction. L’amplitude articulaire passive (AAP) dans l’abduction a été mesurée avec un goniomètre. La co-rélation entre l’abduction et les paramètres radiographiques a été calculée avec le coefficient de Pearson. AAP dans l’abduction a été négativement en corrélation avec l’extension de l’OAC (r = −0.50; P < 0.01) et positivement en corrélation avec l’AL (r = 0.60; P < 0.01). Les résultats suggèrent que le OAC a un rôle important dans la limitation de l’amplitude articulaire maximale pendant l’abduction. De cette étude, nous pouvons conclure que l’extension de OAC et l’amplitude de AAP peuvent être des bons indicateurs des limites articulaires, pendant l’abduction.
