Tratamiento de la inestabilidad acromioclavicular crónica / Treatment of chronic acromioclavicular joint instability

Valorar los resultados de la técnica quirúrgica asistida por artroscopía indicada para el tratamiento de la inestabilidad acromioclavicular crónica (IAC), basada en la fijación coracoclavicular (CC) no-rígida más reconstrucción CC anatómica con aloinjerto tendinoso. Se incluyó a los pacientes con IAC intervenidos entre 2008 y 2012. Las valoraciones clínicas se realizaron mediante el SF36, la EVA y el DASH, aplicados en la visita previa (VPI) a la intervención y en la última visita de seguimiento (UVS). El Constant score y la Escala de Satisfacción General (0-10) se aplicaron en la última visita de seguimiento. Se valoró el desarrollo de subluxaciones secundarias. Se incluyeron 10 pacientes. Edad media 41 años [rango 33-55]. Seguimiento medio 25.50 meses [rango 24-30].En todos los pacientes el tratamiento quirúrgico se indicó cuando el tratamiento conservador fracasó. Cuestionarios aplicados en la VPI y en la UVS: 1. SF36 físico: VPI 29.60 ± 3.41 y UVS 59.58 ± 1.98 (p = 0.000); 2. SF36 mental: VPI 46.57 ± 3.80 y UVS 56.62 ± 1.89 (p = 0.000); 3. EVA: VPI 5.17 ± 2.40 y UVS 1.67 ± 2.07 (p = 0.022); y 4. DASH: VPI 63.33 ± 23.56 y UVS 2.61 ± 1.79 (p = 0.000). El Constant score y la satisfacción general de la UVS fueron 95.56 ± 3.28 y 9.22 ± 0.67 respectivamente. No hubo subluxaciones secundarias. El tratamiento de la IAC mediante un dispositivo de suspensión CC y una reconstrucción anatómica de los ligamentos CC asistida por artroscopía, puede ofrecer una mejoría significativa de la calidad de vida de los pacientes y representa una estrategia que al contemplar una fijación CC mecánica primaria, puede minimizar las posibilidades de fracaso y desarrollo de subluxaciones secundarias.

The purpose of this paper is to assess the results obtained with the arthroscopy-assisted surgical technique for the treatment of chronic acromioclavicular joint instability (CACJI), based on non-rigid coracoclavicular (CC) fixation and anatomical CC reconstruction with a tendinous allograft. Patients with CACJI who underwent surgery between 2008 and 2012 were included in the study. Clinical assessments included SF36, VAS and DASH, applied at the preoperative visit (POV) and at the last follow-up visit (LFUV). The Constant score and the General Satisfaction Score (0-10) were applied at the last follow-up visit. Occurrence of secondary subluxations was assessed. Ten patients were included; mean age was 41 years (range 33-55). Mean follow-up was 25.50 months (range 24-30). Surgical treatment was indicated in all patients after failure of conservative treatment. Questionnaires applied at the POV and the LFUV showed the following results: 1. SF36: physical, POV = 29.60 ± 3.41 and LFUV = 59.58 ± 1.98 (p = 0.000); 2. SF36 mental, POV = 46.57 ± 3.80 and LFUV = 56.62 ± 1.89 (p = 0.000); 3. VAS: POV = 5.17 ± 2.40 and LFUV: 1.67 ± 2.07 (p = 0.022); and 4. DASH: POV = 63.33 ± 23.56 and LFUV = 2.61 ± 1.79 (p = 0.000). The Constant score and the general satisfaction at the LFUV were 95.56 ± 3.28 and 9.22 ± 0.67, respectively. There were no secondary subluxations. Treatment of CACJI with a CC suspension device and arthroscopically-assisted anatomical reconstruction of CC ligaments may provide a significant quality of life improvement to patients. It is a strategy that, upon considering primary mechanical CC fixation, may minimize the chance of failure and occurrence of secondary subluxations.
