Estudio comparativo de la reparación de la rotura de espesor completo del supraespinoso mediante técnica "hilera simple" o "suture bridge" / Comparative study of the repair of full thickness tear of the supraspinatus by means of "single row" or "suture bridge" techniques

RESUMEN

Resumen Objetivo: Analizar si existen diferencias clínicas entre las técnicas "hilera simple" versus "suture bridge" en la reparación artroscópica de roturas de espesor completo del supraespinoso. Material y métodos: Estudio retrospectivo de 123 pacientes con rotura de espesor completo del supraespinoso, intervenidos entre Enero de 2009 y Enero de 2013 (60 hilera simple y 63 suture bridge). La edad media en el grupo suture bridge fue 63.3 años y en el grupo hilera simple, 62.9. Predominio de mujeres (67%) en ambos grupos. En todos los casos, se reparó la hilera medial con anclajes Bio-Corkscrew y la hilera lateral con implantes Bio-PushLock (Arthrex, Naples, FL). Resultados: El valor del test de Constant medio en individuos intervenidos mediante suture bridge fue 76.7 (ponderado 96.5). En hilera simple, fue 72.4 (ponderado 92.8). Se realizó también un análisis estadístico comparativo de cada ítem del test de Constant por separado. La fuerza es el único parámetro del test de Constant estadísticamente significativo y es mayor en el grupo suture bridge. Conclusiones: La reparación de las roturas de espesor completo del supraespinoso mediante suture bridge proporciona resultados clínicos superiores a la reparación en hilera simple, sin existir diferencias estadísticamente significativas (p = 0.298).

ABSTRACT

Abstract Purpose: The purpose of this study is to analyze if there is any difference between the arthroscopic reparation of full-thickness supraspinatus tears with simple row technique versus suture bridge technique. Material and methods: We accomplished a retrospective study of 123 patients with full-thickness supraspinatus tears between January 2009 and January 2013 in our hospital. There were 60 simple row reparations, and 63 suture bridge ones. Results: The mean age in the simple row group was 62.9, and in the suture bridge group was 63.3 years old. There were more women than men in both groups (67%). All patients were studied using the Constant test. The mean Constant test in the suture bridge group was 76.7, and in the simple row group was 72.4. We have also accomplished a statistical analysis of each Constant item. Strength was higher in the suture bridge group, with a significant statistical difference (p < 0.04). The range of movement was also greater in the suture bridge group, but was not statistically significant. Conclusions: Suture bridge technique has better clinical results than single row reparations, but the difference is not statistically significant (p = 0.298).
