Abstract
The purpose of the work – to determine disadvantages of hook plates fixation in acromioclavicular joint dislocations based on a retrospective analysis of patients treated for this pathology.Materials and methods. A total of 112 patients treated for acromioclavicular joint dislocation in the SI “Institute of Traumatology and Orthopedics of the NAMS of Ukraine” between 2011 and 2018 were retrospectively analyzed. Acromioclavicular joint dislocation was fixed with a hook plate in 74 patients (66.1 %). All the patients were divided into 3 clinical groups: Group I – the hook plate was removed up to 4 months, Group II – the hook plate was removed between 4 and 6 months, Group III – the hook plate was removed after 6 months.Results. The results of the treatment were evaluated by Constant–Murley Score before the hardware removal in patients. The following indicators were obtained: in Group I, 6.7 % of patients had good results and 4 % – satisfactory and unsatisfactory results, in Group II, 43.2 % of individuals had excellent and good results and 9.5 % – satisfactory results, in Group III, 19 % had excellent and good results and 17.6 % – satisfactory and unsatisfactory treatment results. 6 months after the hardware removal, in Group I, 8.2 % of patients showed excellent and good results and 2.7 % – satisfactory results, in Group II, 52.6 % of individuals had good and excellent results, in Group III, 20.3 % of persons had excellent and good results and 16.2 % – satisfactory and unsatisfactory treatment outcomes. Failures and complications of hook plates fixation in acromioclavicular joint were observed in 36 patients, among them 18 patients were with type III dislocation and 14 patients had type V dislocation by Rockwood.Conclusions. The best results assessed by the Constant–Murley and Visual analogue scale scores were achieved in the group with the hook plate removal from the acromioclavicular joint after an interval of 4 to 6 months. When the hook plate was removed after a period of more than 6 months, complications such as irreversible changes in the acromioclavicular joint (posttraumatic osteoarthritis, bone tissue defect in the acromion etc.) were observed.

Summary
Оцінюючи результати лікування хворих за шкалою Constant–Murley перед видаленням металофіксаторів, отримали такі показники: в I групі – 6,7 % добрих, 4 % задовільних і незадовільних результатів; у II групі – 43,2 % відмінних і добрих, 9,5 % задовільних результатів; у III групі – 19 % відмінних і добрих, 17,6 % задовільних і незадовільних результатів лікування. Помилки та ускладнення фіксації акроміально-ключичного суглоба спостерігали у 36 пацієнтів – 18 хворих із III типом вивиху та 14 осіб із V типом вивиху за Rockwood. За шкалою Constant–Murley та Візуальною аналоговою шкалою болю найкращі результати лікування отримали у групі, де металофіксатори з акроміально-ключичного суглоба видалені в термін від 4 до 6 місяців.
