Hook Plate Applications in Type 3 Acromioclavicular Dislocations

INTRODUCTION: Backgraund: 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

METHODS: 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.

RESULTS: 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.


DISCUSSION AND CONCLUSION: 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.
