Background:
Dislocation of the acromioclavicular joint (ACJ), accounting for 9%-12% of all shoulder injuries, is a frequent shoulder problem. Clavicular hook plates have proven to be a successful implant choice for surgical management. The benefit of this method is that it preserves the diarthrosis of the ACJ while reducing dislocation. Positive outcomes with this approach have been reported.
Objective:
This study aimed to quantify functional recovery using the Constant Murley Score (CMS) in patients with ACJ dislocations treated with a clavicle hook plate.
Methodology:
The retrospective study was conducted at the orthopedic department of Sheikh Zayed Medical College and Hospital, Rahim Yar Khan, Pakistan, for over one year, from January 20, 2021, to 19 January, 2022. A total of 40 individuals were identified who were operated on for acute ACJ dislocation with hook plates in the department and were included in the research. All patients underwent open reduction and internal fixation with a clavicular hook plate, which was usually removed three months after surgery. The functional outcome was evaluated using the CMS on the day before plate removal, three months after plate removal, and six months following surgery.
Results:
Of the participants, 28 (70%) were male, and 12 (30%) were female. The mean CMS was 72.25 ± 3.95 (satisfactory) at 24 weeks and 90.45 ± 1.9 (excellent) eight weeks after the removal of the plate.
Conclusion:
The hook plate is an excellent choice for treating acute ACJ dislocation. Radiographic and functional assessments indicate that these plates provide good outcomes.
