Abstract
Cada tres segundos una persona sufre una fractura osteoporótica en el mundo y, con el aumento progresivo de la esperanza de vida, se espera que la incidencia se duplique en pocas décadas. Las fracturas óseas osteoporóticas causan dolor permanente, disminuyen la calidad y la esperanza de vida de los pacientes afectados y en muchas ocasiones precisan intervención quirúrgica. Cuando la intervención para tratar la fractura consiste en el implante de un injerto óseo, los autoinjertos, aloinjertos, xenoinjertos e implantes sintéticos son las alternativas disponibles. En este sentido, las conocidas limitaciones asociadas con el uso clínico de autoinjertos, aloinjertos y xenoinjertos continúan impulsando los esfuerzos para desarrollar implantes sintéticos que favorezcan la regeneración ósea, utilizando los principios de los biomateriales y la ingeniería de tejidos. Sin embargo, a pesar de años de esfuerzo, aún no se ha desarrollado el material de reconstrucción ósea perfecto. Por tanto, existe una necesidad médica insatisfecha de implantes capaces de aumentar las posibilidades de devolver al hueso fracturado su forma y función...
Every three seconds a person suffers an osteoporotic fracture worldwide and, with the progressive increase in life expectancy, the incidence is expected to double in a few decades. Osteoporotic bone fractures cause permanent pain, decrease the quality of life and life expectancy of affected patients and often require surgical intervention. When the intervention to treat the fracture consists of the implantation of a bone graft, autografts, allografts, xenografts and synthetic implants are the available alternatives. In this regard, the known limitations associated with the clinical use of autografts, allografts and xenografts continue to drive efforts to develop synthetic implants that promote bone regeneration, using the principles of biomaterials and tissue engineering. However, despite years of effort, the perfect bone reconstruction material has not yet been developed. Therefore, there is an unmet medical need for implants capable of increasing the chances of restoring form and function to fractured bone...
