Acromioclavicular Joint Injuries in Sport

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Radiology

Background:

• Sport-related shoulder injuries, particularly acromioclavicular joint (ACJ) disruptions, are prevalent.
• ACJ injuries involve displacement of the clavicle, graded by severity and direction.
• Clinical diagnosis is essential, but radiographic imaging is crucial for assessing severity and associated injuries.

Purpose of the Study:

• To provide a comprehensive overview of acromioclavicular joint (ACJ) injuries.
• To discuss relevant anatomy, biomechanics, diagnostic methods, and treatment strategies.
• To review potential complications and long-term outcomes for athletes.

Main Methods:

• Review of clinical diagnosis and standard radiographic views for ACJ injury assessment.
• Discussion of nonoperative and surgical management options based on injury severity.
• Analysis of factors influencing long-term outcomes and return to sport.

Main Results:

• ACJ injuries are classified by clavicle displacement, with diagnosis aided by clinical examination and radiography.
• The majority of ACJ injuries are managed nonoperatively, with surgery reserved for specific cases.
• Long-term outcomes are generally favorable, with most athletes returning to sport without limitations.

Conclusions:

• Acromioclavicular joint (ACJ) injuries require accurate diagnosis and appropriate management for optimal outcomes.
• Nonoperative treatment is effective for most ACJ injuries, ensuring a good prognosis for athletes.
• Understanding the biomechanics and classification is key to successful treatment and rehabilitation.
