Recurrence and Pain Analysis in the Treatment Outcomes of Acromioclavicular Joint Dislocation Following Hook Plate Removal

Abstract

Background: The treatment of acute dislocation of the acromioclavicular joint, specifically types III to V, involves various methods, each with its own advantages and disadvantages. Objectives: This study aims to investigate the treatment outcomes of acromioclavicular joint dislocation after hook plate removal, focusing on the recurrence of dislocation and pain in the affected area. Methods: A retrospective statistical study was conducted on 40 patients (18 - 40 years old) who presented with acromioclavicular joint dislocation and received treatment at Golestan and Imam Khomeini (RA) hospitals in Ahvaz between 2013 and 2021. Among the patients, 28 were male and 12 were female, and all were treated using the hook plate method. A follow-up was conducted on all patients after an average duration of one year. Patient data were collected through radiographic analysis and completion of relevant questionnaires to assess the specific objectives of this research. Results: None of the patients treated with the hook plate method required additional surgery due to reduction loss. All patients who underwent re-surgery had their hook plates removed after an average of six months. There were no cases of plate breakage or recurrence after the operation. However, four cases (10% of all patients) reported partial dislocation. The average duration of the hook plate procedure was estimated to be 45 minutes, with an estimated blood loss of 100 cc. Furthermore, complete immobilization after the hook plate procedure lasted between three days and one week. Conclusions: The hook plate method exhibits favorable outcomes, including lower complication rates, reduced postoperative pain, minimal blood loss, shorter treatment duration, and lower surgical costs. Therefore, it is considered a preferred and economically viable treatment option.
