Background: Acute acromioclavicular (AC) joint dislocations are common injuries, particularly among athletes
and individuals exposed to direct shoulder trauma. The management of these injuries varies depending on the
severity of the dislocation, classified by the Rockwood system. While conservative treatment is often effective for
lower-grade dislocations (Type I and II), surgical intervention is typically required for higher-grade injuries (Type
III–VI) to restore stability, maintain function, and prevent chronic pain or deformity. Among the various surgical
techniques available, the use of hook plates has gained popularity due to its effectiveness in providing rigid
fixation and facilitating early mobilization. The hook plate is a contoured metallic implant that stabilizes the AC
joint by engaging beneath the acromion and securing the distal clavicle. This technique offers several
advantages, including strong mechanical stabilization, ease of application, and the ability to restore anatomic
alignment. Studies have shown that hook plates lead to favorable clinical outcomes, with high rates of joint
stability and functional recovery. However, their use is not without complications, which may include subacromial
impingement, osteolysis, and plate-related discomfort.
