Introduction: A pseudoarthrosis is established after a minimum of nine months after the trauma without progressive visible signs of consolidation for three months1. The treatment of nonunion of fractures is expensive, with an estimated cost per case between £ 7,000 and £ 79,000 ($ 10,000 to $ 114,000) .2 There is currently no surgical technique that is considered standard for the treatment of this pathology Objective: To determine the effectiveness of the mixed stabilization treatment with a central medullary nail + external fixator in the patients of the Naval Medical Center based on the radiological consolidation time. Method: Study where the effectiveness of mixed surgical treatment for pseudoarthoris and / or nonunion was evaluated in 21 patients who met inclusion criteria for the surgical procedure from 2016 to 2019 at the Naval Medical Center of Mexico City. Under informed consent. Results: This study included 21 patients who were cared for by the Traumatology and Orthopedics service of the Naval Medical Center, who met the inclusion criteria to be part of this study. The gender distribution in the analyzed patients was predominantly male with n = 17 (81%) and female with n = 4 (19%). The area of injury of the affected limb was n = 12 (57%) for the femur bone and n = 9 (43%) for the tibia bone. Without showing a significant relationship between the affected bone and the healing time. The hypertrophic type was the most common with a frequency of 14 cases (67%), 33% corresponded to the hypotrophic type (n = 7). Conclusions: The mixed surgical fixation and stabilization treatment used in this hospital for the management of pseudoarthrosis was adequate since we obtained an effectiveness of 90.47%, thus providing us with adequate safety in its use.
