Antecedentes. La fractura de escafoides sigue siendo un reto para el ortopedista y para los cirujanos de mano. Objetivo. Mostrar los detalles anatómicos del colgajo óseo del segundo metacarpiano en cadáveres inyectados con látex coloreado de verde y los resultados de la técnica empleada en una serie de pacientes con seudoartrosis de escafoides. Material y métodos. Describimos detalles anatómicos. Todos nuestros pacientes consolidaron, mejoraron en la escala de dolor, no tuvieron deterioro de la movilidad y no presentaron inestabilidad de carpo residual. Resultado. El injerto vascularizado es una opción útil en el manejo de la pseudoatrosis del escafoides. Conclusión. Estudio descriptivo de una serie de casos de pacientes con seudoartrosis de escafoides, tratados con injerto óseo vascularizado por la primera arteria metacarpiana dorsal. Un estudio anatómico inicial antes de emplear la técnica en nuestros pacientes.
Background. The fracture of scaphoid continues being a challenge for orthopedist and hand surgeons. Objective. To show the anatomical details of the bony strip from the second metacarpal in corpses injected with green latex and the results of the chirurgical technique in a series of patients with scaphoid speudartrosis. Materials and methods. We carry out an initial anatomical analysis before employing the chirurgical technique in clinical setting, and then we did a descriptive study of patients with pseudarthrosis of scaphoid, treated with vascularized bony graft by the first metacarpal artery. Results. All patients consolidated and improved in the pain scale, they did not have mobility deterioration or residual carpus instability, after ten years of observations. Conclusions. The vascularized graft is a useful option in the management of the speudartrosis of the scaphoid.
