Background High energy diaphyseal fractures constitute a complicated matter for trauma units and urgent medical and surgical decisions to prompt stabilization of these patients, might leave some skeletal distortions that affect bone union. The objective is to evaluate the safety and efficacy of extracorporeal shockwave therapy (ESWT), as a treatment for patients with atrophic or pseudoatrophic nonunion. Patients and Methods Case series which included 50 patients with nonseptic and stable nonunion diaphyseal fracture of femur and tibia. They received a defined protocol of up to three high-energy ESWT (10.000 shocks per session). Each patient was evaluated with x-rays or CT between 4 and 6 weeks, to determine the necessity to continue the protocol and obtain data about initial periosteal-endosteal responses and its evolution. We analyzed, semi-quantitatively, the volume of the fracture zone from initial CT using a mathematical method to calculate the volume in cylinders, and confronting this data with Winquist Classification. Results 17/25 (68%) tibia and 13/25 (52%) femur nonunion were treated successfully. There were no complications during or after treatment. Conclusions ESWT induced bone healing in an average 60% of cases, which is consistent with current reported literature. CT studies gave some clues to patients’ real condition of fracture anatomy before treatment, allowing a better decision in the orientation of ESWT application for each case. Volumetric Fracture Analysis for Winquist Classification shown that ESWT was able to induce significant bone regeneration in fractures with high volume. This kind of therapy was well accepted in reluctant patients to invasive methods. Highlights

Palabras Claves► complicación ► genu valgo ► osteotomía ► fractura de platillos tibiales ResumenObjetivo Presentar un caso de complicación de fractura de platillos tibiales Schatzker VI y su manejo quirúrgico. Material y Método Se presenta un caso de fractura de platillos tibial Schatzker VI que evoluciona con malalineamiento en valgo secundario a hundimiento del platillo tibial, junto a una revisión de la literatura y la descripción del manejo quirúrgico.Resultados Se realizó una osteotomía en cuña de cierre medial de tibia proximal y se estabilizó con placa bloqueada (TomoFix), con una corrección completa de la deformidad sin complicaciones. Discusión La osteotomía en cuña de cierre medial en tibia proximal es una técnica descrita en el manejo de artrosis secundaria a malalineamiento en valgo de la rodilla. Mediante dos osteotomías iniciadas por la cortical medial hacia la lateral con un fulcro esa última, se retira una cuña de dimensiones conocidas y se mantiene la reducción con algún elemento de osteosíntesis. De esa forma, se permite la corrección angular de la deformidad, previamente planificada. Los resultados en distintas series son en general favorables. Conclusión El malalineamiento de la extremidad posterior a una fractura de platillos tibiales y la consecuente sobrecarga del compartimento afectado en la rodilla, asociado al daño articular, evoluciona con degeneración articular que termina en una artrosis unicompartimental secundaria, la cual puede ser prevenida con el uso de osteotomías correctoras de ejes como la osteotomía de tibia proximal, permitiendo normalizar la distribución de las cargas en los compartimentos mediante la corrección del eje mecánico alterado y así prolongar la sobrevida articular. Nivel de Evidencia Tipo IV, Caso Clínico.
