Arthroscopic Approach to Deltoid Injuries

Area of Science:

• Orthopedic surgery
• Sports medicine
• Anatomy

Background:

• Deltoid ligament injuries can lead to medial ankle instability (MAI).
• Two distinct subgroups of deep deltoid layer injuries have been identified: dynamic MAI and rotational ankle instability (RAI).
• Dynamic MAI typically results from acute trauma to the intermediate deep layer (collicular fibers).

Purpose of the Study:

• To differentiate between dynamic MAI and RAI.
• To highlight the diagnostic challenges of chronic deep-layer deltoid injuries.
• To emphasize the role of arthroscopy in diagnosing and managing these injuries.

Main Methods:

• Clinical examination and radiological assessment were considered.
• Arthroscopy was utilized for definitive diagnosis.
• Management strategies were evaluated based on arthroscopic findings.

Main Results:

• RAI originates from chronic injury to the anterior fibers, often linked to chronic lateral ankle instability.
• RAI is characterized by abnormal talar rotation and translation.
• Chronic deep-layer deltoid injuries present diagnostic difficulties using conventional methods.

Conclusions:

• Accurate diagnosis of dynamic MAI and RAI is crucial for effective treatment.
• Arthroscopy is essential for the precise diagnosis and management of deep deltoid ligament injuries.
• Early arthroscopic intervention can improve outcomes for patients with MAI.
