Resultados funcionales de la prótesis total radiocubital distal: caso clínico y revisión de la bibliografía
2011
espanolLa articulacion radio cubital distal (ARCD) resulta imprescindible para poder elevar objetos contra gravedad. En las lesiones de dicha articulacion, es necesario reconstruir todos los elementos articulares y estabilizadores para poder soportar la fuerzas de tension en muneca y antebrazo y evitar una importante perdida de funcion de la extremidad. La protesis total radiocubital distal promulgada por Scheker es una alternativa novedosa para reparar anatomica y biomecanicamente esta articulacion, ya que los procedimientos previos (reseccion, artrodesis o hemiartroplastia) no han mostrado resultados satisfactorios. Se presenta el caso de una paciente con inestabilidad de muneca por disfuncion de la ARCD en la que se implanto dicho modelo protesico y se desarrollo un programa de rehabilitacion posquirurgico previamente no descrito, de 12 semanas de duracion. Se exponen unos resultados funcionales excelentes y se comparan con los publicados en la bibliografia EnglishThe distal radioulnar joint (DRUJ) is very important for lifting objects. When the DRUJ is injured, all of the joint elements and stabilizing elements must be reconstructed in order to be able to support the tension forces on the wrist and forearm and avoid significant loss of limb functions. The total DRUJ prosthesis developed by Scheker is a new alternative to be taken into account. It seems to allow anatomical and biomechanical repair of the DRUJ. Moreover, it gives better results than previously published procedures (removal, arthrodesis and hemiarthroplasty of the DRUJ). We present the case of a woman with symptomatic wrist instability due to dysfunction of the DRUJ who underwent Scheker's arthroplasty. In the postoperative period, we designed a new 12-week rehabilitation program, which gave us an excellent result. Finally we discuss our case, comparing them with those previously reported in the literature
