[Grade III acromioclavicular dislocation treated with a minimally invasive approach]. / Luxaciones acromioclavicular grado III con técnica mínimamente invasiva.

OBJECTIVE: To determine the efficacy of minimally invasive surgery (MIS) in the treatment of type III acromioclavicular dislocations using the UCLA and DASH evaluations. MATERIAL AND METHODS: Prospective, longitudinal, observational study; clinical series of patients with a diagnosis of type III acromioclavicular dislocation who underwent MIS consisting of percutaneous reduction, placement of a 4.5 mm cortical screw, an 11 mm metallic washer and 1.6 mm Kirschner nails at the Polanco Red Cross Hospital from July 2007 to July 2009. The evaluations were done using the UCLA test and the DASH questionnaire. RESULTS: The total number of patients was 42; 5 females and 37 males. According to the UCLA test, 86% of them had excellent to good results and 14% partial to poor results. The results of the DASH questionnaire were as follows: 80% had no difficulty to mild difficulty; 18% had moderate to severe difficulty, and 2% had disability for performing daily life activities. CONCLUSIONS: MIS is a good treatment for the management of type III acromioclavicular dislocation with long-term results based on the UCLA test and the DASH questionnaire.
