ABSTRACT Objective: To evaluate medial joint space in affected and normal contralateral hips in patients with Legg-Calvé-Perthes disease (LCPD). Methods: To compare joint space, femoral head extrusion (FHE), medial space coefficient (MSC) of the hip, and femoral head width (FHW) in affected and normal hips, using 127 radiographs of patients with unilateral LCPD and considering age groups under and over six years old as well as their disease stage. Results: No statistically significant differences were observed regarding MSC between normal and affected hips regardless of disease staging. However, medial joint distance was significantly greater in affected hips than in normal hips. In the necrosis and fragmentation phase, distance from medial space in affected hips was significantly greater than in contralateral normal hips. Comparing only affected hips, MSC and FHW showed statistically significant differences and the group > 6 yo presented higher values. Among normal hips, the group < 6 yo presented a statistically significant difference considering the MSC and FHW. Conclusions: No statistically significant difference was found between the medial joint space of affected and normal hips, except for early stages of the disease (necrosis and fragmentation). The isolated use of radiographic study is insufficient in LCPD and the lack of complementation with other exams, such as magnetic resonance, can delay diagnosis of and onset of treatment for the disease.

Como la última de las religiones monoteístas reveladas, el Islam se ha acompañado de un esfuerzo de organización centralizada de una comunidad destinada a la expansión. Asimismo, la revelación coránica se ha aplicado a la institucionalización de un derecho musulmán, el cual ratifica a un patriarcado que demanda de las mujeres maternidades numerosas, únicas garantes de la riqueza y el desarrollo de la comunidad. Sin embargo, el derecho instituido varía sensiblemente en el mundo islámico, dependiendo de los diferentes ritos, las escuelas jurídicas y los Estados. De modo que, en el seno de las diferentes sociedades musulmanas, las tradiciones pueden haber orientado diferentemente el derecho, así como algunas rivalidades de poder entre el patriarcado y la maternidad. Hoy en día, los cambios hacia maternidades elegidas son ineludibles, tanto por las necesidades de gestión de los Estados como por la valiente lucidez de las mujeres, a pesar de la violencia reaccionaria de los islamistas radicales.
