CAPOMASSI, Miguel A et al. Rotura del bíceps distal: Evaluación de resultados con técnica de doble fijación. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2013, vol.78, n.4, pp.171-179. ISSN 1852-7434.

Background: The distal biceps rupture is an unusual lesion produced when an eccentric force is applied to the bent elbow. The aim of this work is to analyze the results for the reinsertion of the distal biceps with a double fixation technique of cortical button and biotenodesis interference screw through a single anterior incision. Methods: Between August 2008 and February 2013 we registered 19 cases of distal biceps rupture, surgically treated through an anterior limited procedure. The last 17 consecutive cases were treated with double fixation using an extracortical button and biotenodesis screw and are part of this study. All the patients were males with a median age of 41 years (range 27-59). The patients were evaluated using the DASH questionnaire and the subjective/ objective scoring system of Andrews and Carson, controlling the flexion and supination forces with the British Medical Research Council scale, modified by Mackinnon and Dellon (M0-M5). Results: DASH questionnaire obtained a median value of 1.7 (0-5.83), and the Andrews and Carson score had a median value of 195 (170-200) for the total; with 15 excellent results and 2 good results. All patients achieved a force of M5 in flexion and supination of the forearm. The follow-up had a median of 12 months (4-32). Complications were registered in two patients, both recovered ad integrum. Conclusion: The described technique proved to be both reliable and effective, giving satisfactory results with a low complication rate.
