Abstract

Background: Injuries to the acromioclavicular (AC) joint and fractures of the lateral end of the clavicle are prevalent in young individuals and athletes, posing significant challenges in orthopedic management. The use of a clavicle hook plate for the treatment of these injuries has been a subject of interest in recent orthopedic research.


Materials and methods: Conducted as a cross-sectional study at a private hospital from August 2021 to January 2022, it included 25 cases based on specific inclusion criteria: AC joint disruptions of Tossy type 3 and fractures of the lateral end of the clavicle of Neer type 2 and 3. Participants underwent open reduction and internal fixation with a clavicle hook plate. The study utilized the Quick DASH score and Constant-Murley score for outcome assessment, and the data were analyzed using SPSS version 25.


Results: The study demonstrated predominantly positive outcomes, with a majority of patients showing good to excellent recovery based on Constant-Murley and Quick DASH scores. The mean age of participants was 42.52 years, with a balanced distribution in terms of gender and injury side. Notable complications included hook cut-out, impingement, and osteolysis at the tip of the hook. However, these complications were reversible upon implant removal.


Conclusion: The study indicates that clavicle hook plate fixation is effective for treating lateral end clavicle fractures and AC joint disruptions, leading to improved shoulder function. However, limitations like a small sample size, absence of a control group, potential bias, and a short follow-up period underscore the need for larger, randomized trials to confirm and assess long-term safety and efficacy.
