Abstract
Purpose

Assess the short term functional and radiological results of using the AO hook plate in type III acute acromioclavicular joint dislocations.

Materials and methods

During the 2006–2008 period, we performed 70 interventions due to injuries (fractures and dislocations) of the clavicle, 26 of them being acute or chronic acromioclavicular joint dislocations. We analyzed the results of 11 acute cases treated with an AO hook plate. This group had an average age 38 years, 6 cases due to traffic accidents and 5 were related to accidents at work. The plate was withdrawn at an average of 9 weeks (range 6–12 weeks).

Results

The functional outcome of the series according to the Constant test of acute AC joint dislocations was a mean of 94 with the score on the VAS of 2.1. Average time to surgery for acute joint dislocations was 9 days. All the patients, except for one, had subacromial physical discomfort during physiotherapy with the abducted arm that disappeared after removing the plate. We observed a case of loss of reduction after removal of plate and did not observe any other significant complications.

Conclusions

Surgical treatment of acute AC joint dislocations with AO hook plate, without reconstruction of the coracoclavicular ligaments, offers good results. We observed few complications, allowing the patients to return to work early without sequels.

Resumen
Objetivo

Valorar los resultados funcionales y radiológicos a corto plazo de la utilización de la placa gancho AO en el tratamiento quirúrgico de las luxaciones acromioclaviculares (AC) agudas de tipo III.

Material y método

Durante el período 2006–2008 se han realizado 70 intervenciones por lesiones (fracturas y luxaciones) de la clavícula, 26 de ellas luxaciones AC agudas o crónicas. Hemos analizado los resultados de las luxaciones agudas tratadas con una placa gancho AO.

La serie constaba de 11 luxaciones AC de tipo III, con una edad media de 38 años. En 6 casos ocurrieron por accidente de tráfico y en 5 casos ocurrieron por etiología laboral. La media de la retirada de la placa fue a las 9 semanas (rango de 6–12 semanas).

Resultados

Los resultados funcionales de la serie según el test de Constant fueron de 94 puntos de media y la escala analógica visual fue de 2,1. El tiempo medio hasta la cirugía de las luxaciones agudas fue de 9 días. Todos los pacientes, menos uno, presentaban molestias subacromiales durante la fisioterapia y que desaparecieron al retirar la placa. Hemos observado un caso de pérdida de reducción tras la retirada de la placa y no hemos observado otras complicaciones significativas.

Conclusiones

El tratamiento quirúrgico de las luxaciones AC agudas con la placa gancho AO, sin la reconstrucción de los ligamentos coracoclaviculares, ofrece un buen resultado. Hemos observado pocas complicaciones y ha permitido la reincorporación laboral de los pacientes sin secuelas.
