RESUMO
Introducción: Las fracturas humerales diafisarias multifragmentarias con extensión proximal son patrones infrecuentes de lesión causados principalmente por trauma de alta energía. La forma anatómica del húmero, la presencia de la tuberosidad deltoidea y la proximidad del nervio radial al surco radial representan retos a tratar, por ello se recomiendan incisiones mínimamente invasivas y la estabilización de la fractura con placa proximal humeral internal locking system. Objetivo: Demostrar la eficacia de la técnica minimally invasive plate osteosynthesis con el moldeamiento helicoidal de la placa proximal humeral internal locking system. Presentación del caso: Paciente de 29 años que sufrió accidente de tránsito y presentó fractura diafisaria multifragmentaria extendida al húmero proximal. Se trató con la técnica minimally invasive plate osteosynthesis y placa helicoidal proximal humeral internal locking system. Alcanzó la consolidación completa y rápida recuperación funcional. Conclusiones: La técnica minimally invasive plate osteosynthesis con placa helicoidal proximal humeral internal locking system es una opción quirúrgica eficaz y segura para las fracturas humerales diafisarias multifragmentarias con extensión proximal, ya que preserva la inserción muscular deltoidea, mejora el contacto placa hueso con riesgo mínimo de lesión neurológica axilar y radial, favorece la curación ósea y mejora el resultado funcional.
Introduction: Multifragmentary diaphyseal humeral fractures with proximal extension are infrequent patterns of injury caused mainly by high-energy trauma. The anatomical shape of the humerus, the presence of the deltoid tuberosity and the proximity of the radial nerve to the radial groove represent challenges to be treated, therefore minimally invasive incisions and fracture stabilization with the proximal humeral internal locking system plate are recommended. Objective: To establish the efficacy of the minimally invasive plate osteosynthesis technique with helical molding of the proximal humeral plate internal locking system. Case report: We report the case of a 29-year-old patient who suffered a traffic accident and had a multifragmentary diaphyseal fracture extended to the proximal humerus. He was treated with the minimally invasive plate osteosynthesis technique and the humeral proximal helical plate internal locking system. He achieved complete consolidation and rapid functional recovery. Conclusions: The minimally invasive plate osteosynthesis technique with the humeral proximal helical plate internal locking system is an effective and safe surgical option for multifragmentary diaphyseal humeral fractures with proximal extension, since it preserves the deltoid muscle insertion, improves bone-plate contact with minimal risk of fracture. Axillary and radial neurological injury, promotes bone healing and improves functional outcome.
