“…Internal or external bone fixators are mechanical means in bone reconstruction ensuring the stability of a fractured or osteotomized bone, bone compression or distraction, and guided fragment transport. The Ilizarov system that comprises circular external fixator modules and techniques of their application for specific clinical situations[ 4 ] has experienced many modifications over the last 50 years[ 9 , 10 ]. Development and progress in bone fixation devices have been greatly influenced by the Ilizarov’s “revolutionary entrance” to the world of orthopedics and aimed at constant improvement of clinical outcomes and patients’ comfort.…”

“…External fixators (the Ilizarov apparatus, hybrid and hexapod external fixators, the Orthofix limb reconstruction system, the Taylor Spatial Frame) are the main devices in bone reconstruction surgery that involves new bone formation and correction[ 5 , 6 , 10 ]. The conventional circular external fixator has been enhanced with innovative configurations, pin and ring modifications, wire and half-pin coatings that can potentially decrease infection rates in thick soft-tissue limb segments while parts fabricated from carbon fibers make the whole circular frame weight lower[ 5 , 9 ]. Monolateral rail external systems have been used for a better comfort of patients undergoing a bone lengthening procedure in the femur[ 6 ].…”

The Ilizarov method is one of the current methods used in bone reconstruction. It originated in the middle of the past century and comprises a number of bone reconstruction techniques executed with a ring external fixator developed by Ilizarov GA. Its main merits are viable new bone formation through distraction osteogenesis, high union rates and functional use of the limb throughout the course of treatment. The study of the phenomenon of distraction osteogenesis induced by tension stress with the Ilizarov apparatus was the impetus for advancement in bone reconstruction surgery. Since then, the original method has been used along with a number of its modifications developed due to emergence of new fixation devices and techniques of their application such as hexapod external fixators and motorized intramedullary lengthening nails. They gave rise to a relatively new orthopedic subspecialty termed “limb lengthening and reconstruction surgery”. Based on a comprehensive literature search, we summarized the recent clinical practice and research in bone reconstruction by the Ilizarov method with a special focus on its modification and recognition by the world orthopedic community. The international influence of the Ilizarov method was reviewed in regard to the origin country of the authors and journal’s rating. The Ilizarov method and other techniques based on distraction osteogenesis have been used in many countries and on all populated continents. It proves its international significance and confirms the greatest contribution of Ilizarov GA to bone reconstruction surgery.

“…Los elementos de fijación externa se indican principalmente para la fijación temporal de fracturas producidas después de un traumatismo, también para corregir deformidades, tratamiento de defectos, entre otros casos en los que la intención es tener un daño mínimo de los tejidos blandos (Bliven et al, 2019).…”

La presencia de animales politraumatizados es frecuente en la práctica diaria del médico veterinario, entre las patologías óseas más frecuentes son las fracturas del esqueleto apendicular, estas pueden venir acompañadas de lesiones torácicas, abdominales, craneales y vertebrales, por lo cual, se ha planteado como objetivo de la investigación: analizar las diferentes complicaciones asociadas a las fracturas del esqueleto apendicular en caninos y los tratamientos que existen en la actualidad, para esto se recurrió a la investigación bibliográfica de diferentes bases de datos, las publicaciones científicas revisadas corresponden a los últimos cinco años; entre los temas tratados en la investigación se detallan las complicaciones asociadas a las fracturas apendiculares en caninos, elementos de osteosíntesis utilizados frecuentemente en el tratamiento de fracturas apendiculares, tratamiento cerrado u ortopédico de fracturas apendiculares, entre otros, los cuales fueron descritos en la literatura, las principales complicaciones asociadas con las fracturas apendiculares en caninos, las lesiones de otros tejidos aparte del hueso, y el abordaje radiológico mediante el uso de los diferentes elementos de fijación utilizados para tratar al paciente, de lo cual se concluye que en la actualidad los métodos a los que se recurre con mayor frecuencia para el tratamiento de fracturas apendiculares son los métodos de fijación interna, principalmente los tornillos, placas y clavos intramedulares, de estos, debido a sus ventajas, entre estas: menor agresión de partes blandas, menor tiempo quirúrgico, mínimo abordaje quirúrgico y su extracción es fácil.

“…The concept of external fixation was proposed as an alternative immobilization method to plaster casts, internal fixation, and traction [ 10 ]. External fixation devices require the use of pins/wires that are needed to be inserted into the tissue and bone and then secured to the external part to provide support and to hold the broken bones in a proper position [ 11 ].…”

Optimization of a Patient-Specific External Fixation Device for Lower Limb Injuries

et al. 2021

The use of external fixation devices is considered a valuable approach for the treatment of bone fractures, providing proper alignment to fractured fragments and maintaining fracture stability during the healing process. The need for external fixation devices has increased due to an aging population and increased trauma incidents. The design and fabrication of external fixations are major challenges since the shape and size of the defect vary, as well as the geometry of the human limb. This requires fully personalized external fixators to improve its fit and functionality. This paper presents a methodology to design personalized lightweight external fixator devices for additive manufacturing. This methodology comprises data acquisition, Computer tomography (CT) imaging analysis and processing, Computer Aided Design (CAD) modelling and two methods (imposed predefined patterns and topology optimization) to reduce the weight of the device. Finite element analysis with full factorial design of experiments were used to determine the optimal combination of designs (topology optimization and predefined patterns), materials (polylactic acid, acrylonitrile butadiene styrene, and polyamide) and thickness (3, 4, 5 and 6 mm) to maximize the strength and stiffness of the fixator, while minimizing its weight. The optimal parameters were found to correspond to an external fixator device optimized by topology optimization, made in polylactic acid with 4 mm thickness.
