Hook plate applications in type 3 acromioclavicular dislocations

Abstract

Acromioclavicular (AC) joint dislocations are caused by sports injuries fall from height or traffic accidents. While the treatment of Type 1 and Type 2 in AC dislocations is conservative, the treatment of Type 4, 5 and 6 is surgery. Treatment of type III dislocations is controversial. In this study, we aimed to investigate the functional results of patients who surgical treatment by using clavicle hook plate in Type III AC joint dislocations 21 patients (18 males, 3 females; mean age 34 years) with Type III AC joint dislocation who were admitted to our clinic between 2015-2017 were treated with clavicle hook plate. The surgical results of the patients at the 6th month were evaluated according to the Constant score. Of the total 21 patient included in the study, n=18 were male (%86), and n=3 were female (%14). All patients were treated with clavicular hook plate. The average follow-up after treatment is 11 months. Functional results were obtained according to Constant scoring. There was no infection after surgery. Plaque irritation occurred in 2 patients and plaque was removed due to prolonged pain. 1 patient had recurrence. Although conservative treatment of Type 3 AC dislocations can provide adequate functional results in the long term, we believe that early results of the surgical treatment using clavicle hook plate is a reliable and effective method especially in the young age group.
