resumen | La incipiente construcción de la legitimidad de los barrios de vivienda pública de la segunda mitad del siglo xx como patrimonio ordinario de calidad requiere el desarrollo de medidas para su protección y rehabilitación. Estos barrios son innovadores arquitectónica y urbanísticamente, al tiempo que están sometidos a procesos de destrucción por la presión inmobiliaria ligada a su centralidad, y de degradación por las reformas individuales e incluso por políticas insuficientes o inadecuadas de rehabilitación estrictamente funcional. Se expone la evolución del concepto de "patrimonio ordinario" aplicado a los conjuntos de vivienda social, y cómo esta noción aparece recogida en las normativas y prácticas europeas y nacionales. El propósito es considerar la situación de los barrios de promoción oficial de Madrid como objeto patrimonializable a través del estudio de tres barrios representativos del Madrid de los años 1940, 1960 y 1980, del que se extraen conclusiones generalizables a otros barrios de promoción oficial. palabras clave | patrimonio, renovación urbana, vivienda. abstract | The construction of the legitimacy of social housing neighborhoods built in the second half of the 20th century as ordinary and qualitative heritage, calls for measures for their safeguard and renewal. These neighborhoods are innovative both from an architectural and an urban perspective; however, they are also submitted to real estate speculation processes due to their central location, to degradation processes derived from inhabitants' interventions, or even insufficient or inadequate functional renewal. The evolution of the concept of heritage regarding social housing neighborhoods is explained, as well as its adjustment to national-level and European regulations and practices. Lastly, the situation of Madrid's social housing neighborhoods as heritage is analyzed through the study of three case studies that are typical for the public housing built in the 1940's, 1950's and 1980's, from which general conclusions regarding Madrid's social housing neighborhoods can be extracted. keywords | heritage, urban renewal, housing.
Intra-articular injuries are common after dislocation and fracture of the hip joint and can be addressed using hip arthroscopy. The most common indications for this procedure are loose bodies, labral tears and chondral defects. In addition, preexisting femoroacetabular impingement can be addressed at the time of surgery. Arthroscopically guided fracture reduction and fixation has been described. We present two case reports of intra-articular lesions after traumatic hip dislocation. The first is a case of a man with an anterior labral tear and loose bodies after closed hip reduction. The second case is a man with a large anterior labral tear with preexisting femoroacetabular impingement. Both of them were treated by arthroscopic debridement of the unstable labrum. In addition loose bodies were removed in the first patient and a femoral osteoplasty was performed in the second patient. Hip arthroscopy has proven to be a safe and effective surgical technique for treating specific post-traumatic lesions and preexisting femoroacetabular impingement. The current case reports provide an overview of the indication for hip arthroscopy following traumatic injuries to the hip.
