Comparación de técnicas quirúrgicas para la lesión del manguito de los rotadores: costo-resultado

Abstract

Introduction: Currently, to manage rotator cuff injury (RCI), there is a tendency to replace mini-open (MO) surgery with arthroscopy, but results and costs are controversial. Objective: To analyze the cost-result of surgical techniques for RCI. Material and methods: A partial economic evaluation of cost-result type was performed on 113 patients with RCI surgically operated by mini-open technique (n = 6), or arthroscopy (n = 91), or both (n = 16). Direct costs included: hospital stay, days of work disability, surgery, implants (anchors), medical assessments, laboratory and imaging. One-year shoulder functionality was evaluated with Constant-Murley scale (EscC-M). Results: The MO technique was the most economical (X = $42,950.60 MXN) and the most expensive was the arthroscopy + MO with anchors (X = $89,594.80 MXN); with a non-significant difference in shoulder functionality (EscC-M = 56.33 ± 7.0 vs. 64.25 ± 9.0 points, respectively) (p > 0.05; Kruskal-Wallis; post hoc Mann-Whitney). Difference of $46,644.1 MXN between techniques corresponded to 7.92 points. There was a mild relationship between the technique and the functionality of shoulder (rs = 0.26; p = 0.005; Spearman). Conclusion: The mini-open technique showed best cost-result, with similar functionality in shoulder to that obtained with the more expensive technique.

Objetivo: Analizar el costo-resultado de las técnicas quirúrgicas para la LMR. Material y métodos: Se realizó una evaluación económica parcial de tipo costo-resultado a 113 pacientes con LMR intervenidos mediante técnica miniopen (n = 6) o artroscopía (n = 91) o ambas (n = 16). Los costos directos incluyeron: estancia, días de incapacidad laboral, cirugía, implantes (anclas), valoraciones médicas, laboratorio e imagen. Se evaluó la funcionalidad del hombro a un año mediante la escala de Constant-Murley (EscC-M). Resultados: La técnica MO fue la más económica (X = $42,950.60 MXN) y la más costosa fue la artroscopía + MO con anclas (X = $89,594.80 MXN); con una diferencia no significativa en la funcionalidad del hombro (EscC-M = 56.33 ± 7 vs 64.25 ± 9 puntos, respectivamente) (p > 0.05; Kruskal-Wallis; post hoc Mann-Whitney). Una diferencia de $46,644.10 MXN entre técnicas correspondió a 7.92 puntos. Hubo relación leve entre la técnica y la funcionalidad del hombro (rs = 0.26; p = 0.005; Spearman). Conclusión: La técnica mini-open mostró mejor costo-resultado, con una ganancia en la funcionalidad de hombro similar a la que se obtiene con la técnica más costosa.
