Se realizó la presentación de un caso con un tumor de células gigantes en el extremo distal del fémur derecho a nivel del cóndilo femoral interno. Se retira quirúrgicamente, previo estudio, donde se confirmó el diagnóstico a través de la biopsia. En dicho proceder se efectuó un raspado extenso de la lesión respetando la superficie articular del cóndilo femoral, rellenando la cavidad con la hidroxiapatita HAP-200 ®, sin necesidad de apoyar dicho acto con una osteosíntesis interna o externa, sólo con una calza de yeso por 6 semanas. El seguimiento del paciente ha sido, hasta la fecha, de 6 años y no se ha reportado ninguna recidiva o metástasis, con una osteointegración positiva del biomaterial, lográndose la curación ósea y una función articular sin restricción.

Introduction: Long bones fractures are responsible for prolonged periods of incapacity and economic losses. New therapies for shortening the time of consolidation are needed. Thus, the purpose of this clinical study was to evaluate the efficacy of noise plus weight-bearing over the bone consolidation of tibial shaft fractures., Methods: In this clinical trial, 12 patients with tibial shaft fractures were recruited during a 24-month period. Participants were treated with intramedullary nails and randomized to two groups: an experimental group and a control group. Both groups underwent a rehabilitation program consisting of two daily walking sessions with progressive weight-bearing. Simultaneously, the experimental group received a noise stimulus on the fracture site with intensities of 0.1-0.6 N and frequencies of 0.1-50 Hz. Radiographic consolidation was evaluated by Radiographic Unión Scale of Tibia., Results: X-ray consolidation was achieved at 18.6 ± 3.6 weeks and 27.2 ± 6.9 weeks, for experimental and control group, respectively (p < 0.05). Recovery of mobility ranges in the knee and ankle was faster in the experimental group than in the control group., Conclusions: This new method to stimulate fracture consolidation has the following advantages: it is effective, portable, easy to use, and inexpensive., (Copyright: © 2019 Permanyer.)
