   Abstract: [Objective] To compare the clinical outcome of hinged acromion-claricle plate developed by ourselves versus conventional hook plate for treatment of dislocation of acromioclavicular joint. [Methods] From October 2016 to October 2017,a total of 68 patients (68 shoulders) who were candidates of surgical treatment for acromioclavicular dislocation were randomly divided into two groups. Of them, 32 patients had open reduction and internal fixation (ORIF) with the hinged acromion-clavicle plate (the hinged plate group) , while the remaining 36 patients were treated with conventional clavicular hook plate (the hook plate group) . The operation time, incision length, intraoperative blood loss, complications, Constant score and parameters measured radiographically were compared between the two groups. [Results] All the patients in both groups had surgical procedures performed successfully without iatrogenic neurovascular injuries. There were no statistically significant differences in operation time, intraoperative blood loss between the two groups (P<0.05) . By contrast, only 2 patients with diabetes got superficial in the hinged plate group, whereas 5 patients of considerable shoulder pain, 1 of superficial wound infection and 4 of abduction limitation were noticed in the hook plate group, therefore, the hinged plate group had significantly less complications than the hook group (P<0.05) . All patients were followed up for 12~18 months with an average of (15.243.57) months. The Constant score significantly increased over time in both groups (P<0.05) . The hinged plate group proved significantly superior to the hook plate group in Constant score at each time point after operation (P<0.05) , although no a statistically significant difference was found before operation in the score between them (P>0.05) . In term of radiographic assessment, the hinged plate group had significantly less acromioclavicular distance than the hook plate group postoperatively (P<0.05) , despite the fact that no a statistically significant difference in coracoclavicaular distance was noticed postoperatively between the two group (P>0.05) .[Conclusions] This hinged acromion-clavicle plate not only achieve satisfactory reduction of acromioclavicular dislocation similar to the hook plate, but also more greatly facilitate the function recovery than the hook plate.
