Fracturas Supracondíleas Humerales Pediátricas. Comparación de dos Técnicas de Reducción

Abstract

Objective: To analyze the results of the surgical technique placement of Kirschner pins lateral versus crossed in the management of supracondylar fractures of the humerus in pediatric patients. Methodology: All pediatric patients with humeral supracondylar fracture who required surgical intervention and were subsequently evaluated 24 hours and 6 months after surgical treatment to observe and compare the differences between each patient. surgical technique used. Taking into account the acute and late complications that occurred, through an analysis with the Mann-Whitney test. Results: For the present studies, 44 pediatric patients were evaluated, of whom 70% were men and 30% women, in whom nerve and angular complications presented without any significant importance with the sex and age of the patients, with ulnar nerve involvement being the most frequent with 33% in cross placement. When carrying out the comparison with discrimination of variables, it is obtained that the placement laterally presents fewer early and late post-surgical complications and that such are not due to chance. Or the present study, it is considered that a placement of Kirschner pins laterally regardless of the member, age, gender or classification; leads to better post-surgical results. Limitations or implications: In the present study, the type of mechanical damage that causes this type of fracture was not included, nor was the Baumann angle considered. Another limitation inherent in the pediatric population is the ability of the examiner to detect a neurological deficit, especially in young patients since reports of a physical examination are always subjective. Furthermore, given the limited details of the specific damage mechanism, the number of damages caused by high-energy mechanisms may be underestimated. Originality or value: Its importance lies in the fact that both surgical techniques were performed by the same surgeons and that it is a study in the mexican population, being a contribution to the literature of this country. Findings or conclusions: Both surgical techniques present post-surgical results with cases of nerve injury, angular deformity, pain and persistent edema, but the one that presents them less frequently in the technique of placement of Kirschner pins laterally, in addition to causing statistical significance in terms of the decrease of presenting cubitus valgus in the late follow-up of the patients.
