Suplementación en osteosíntesis de fracturas de húmero proximal con aloinjerto de peroné
Resumen
Las fracturas de húmero proximal constituyen la tercera fractura osteoporótica en frecuencia. Con una población cada vez más añosa y con la osteoporosis como uno de los principales factores de riesgo de fracaso de la osteosíntesis, se requieren nuevas técnicas de mejora de la fijación que impidan el desplazamiento en varo de la cabeza humeral. En los últimos años no sólo se han mejorado los sistemas de placas al añadir tornillos de bloqueo sino que además se han desarrollado técnicas como la suplementación con tornillo inferomedial, la cementación de los tornillos o el aporte de injerto estructural. En este estudio presentamos dos casos de fracturas de húmero proximal en pacientes con mala calidad ósea que fueron tratados con aloinjerto estructural de peroné intramedular y hacemos una revisión bibliográfica al respecto. Abstract Proximal humerus fractures constitute the third osteoporotic fracture in frequency. With an increasingly elderly population and with osteoporosis as one of the main risk factors for osteosynthesis failure, new fixation improvement techniques are required that prevent varus displacement of the humeral head. In recent years, not only have plate systems been improved by adding locking screws, but techniques such as inferomedial screw supplementation, screw cementation or structural grafting have also been developed. In this study, we present two cases of fractures of the proximal humerus in patients with poor bone quality who were treated with structural allograft of the intramedullary fibula and we make a bibliographic review in this regard.Citas
