Relación entre laxitud articular e inestabilidad glenohumeral. Un meta-análisis de la literatura
2014
El objetivo de esta revision sistematica fue establecer si existe alguna relacion entre la inestabilidad glenohumeral y cualquier forma de laxitud articular. Se realizo un algoritmo de busqueda de acuerdo a las guias de PRISMA en las bases de datos de PubMed, OVID, Sport Discus, Scopus y Web of Science usando las palabras clave “(Ligament Laxity OR ligamentous Laxity OR generalized joint laxity) AND (shoulder dislocation OR shoulder subluxation OR shoulder luxation OR Shoulder instability) hasta Diciembre de 2013. Se incluyeron los articulos en lengua inglesa que describan algun tipo de relacion objetiva, entre inestabilidad glenohumeral y laxitud articular focal o generalizada. Fueron excluidos estudios en cadaveres, o in vitro, o que contengan pacientes con enfermedades del tejido conectivo, reportes de casos, reportes biomecanicos, revisiones, cartas de editores y notas tecnicas. La busqueda arrojo un total de 603 articulos de los cuales 15 cumplian los criterios de inclusion. Segun la evidencia encontrada la laxitud articular podria influir en la inestabilidad glenohumeral, pero debido a la gran diversidad de formas en que ambas se relacionan y las diferentes maneras de diagnosticarlas es imposible obtener un analisis estadistico que provea informacion confiable. Los cirujanos ortopedistas debemos unificar criterios en relacion a la definicion y a los test para evaluar laxitud articular e inestabilidad glenohumeral y, asi de esta manera, poder obtener informacion mas confiable y objetiva. Nivel de Evidencia: IV. Tipo de Estudio: Revision Sistematica... The aim of this meta-analisis was to establish whether there is a relationship between any kind of articular laxity and shoulder instability. The search algorithm according to the PRISMA guidelines of PubMed, OVID, Sport Discus, Scopus and Web of Science databases using the keywords “(Ligament laxity OR ligamentous laxity OR generalized joint laxity) AND (shoulder dislocation OR shoulder subluxation OR shoulder luxation OR shoulder instability) until December of 2013 was done. Inclusion Criteria: articles in English showing relationship between any types of glenohumeral instability with focal or generalized joint laxity. Studies on cadavers, or in vitro, involving patients with connective tissue diseases, case reports, biomechanical reports, revisions, letters to editors and technical notes were excluded. Fifteen articles of 603 reference of the search were included. Joint laxity may influence shoulder instability. We found diversity not only in how to relate joint laxity and glenohumeral instability buy also different ways of diagnosing. This makes it difficult to obtain statistical analysis that can provide reliable data. Additional efforts aiming to provide consensus are required to clarify this subject. Orthopedics surgeons must unify criteria regarding lax shoulder as well as glenohumeral instability and thus can get more objective and reliable data. Level of Evidence: IV.
