Tratamiento de la disociación estática escafolunar utilizando una plastia de palmar mayor: resultados preliminares

Abstract

PurposeTo examine the early results of a reconstruction of the dorsal and volar portions of the scapholunate ligament using the flexor carpi radialis for the treatment of static scapholunate instability. MethodsFrom June 2012, 7 patients with scapholunate instability underwent reconstruction of the dorsal and volar portions of the scapholunate ligament using the flexor carpi radialis. Mean patient age at surgery was 44 years. The minimum follow-up was 18 months (12-35 months). ResultsThe functional outcome according to Green and O’Brien was good in 6 patients and satisfactory in the other one, and mean scores of 6.3 and 80 according Quick-Dash and modified Mayo, respectively. On the X-rays, the mean preoperative scapholunate gap and scapholunate angle was 4.6mm at baseline and 2.4mm, and 59.3° and 46.6°, respectively, at the end of follow-up. ConclusionsThe clinical and radiographic findings at follow-up were good. This technique enables the reconstruction of the dorsal and volar portions of the scapholunate interosseous ligament, and enables scaphoid-trapezium-trapezoid ligaments to be strengthened and to regain normal tension, rebuilding the carpal architecture effectively. Although the results are encouraging, more patients and longer follow-up is needed to reach definitive conclusions.
