Subtalar instability

Area of Science:

• Orthopedics
• Sports Medicine
• Biomechanics

Background:

• Subtalar instability is a challenging condition frequently associated with lateral ankle instability.
• Its diagnosis is often difficult due to complex biomechanics and varied clinical presentations.

Purpose of the Study:

• To elucidate the relationship between subtalar joint kinematics and joint stability.
• To enhance understanding of the clinical presentation of subtalar instability.
• To review diagnostic radiographic modalities and surgical treatment options.

Main Methods:

• Exploration of subtalar joint kinematics and ligamentous contributions to stability.
• Review of clinical diagnostic criteria for subtalar instability.
• Evaluation of radiographic imaging techniques and their diagnostic accuracy.
• Discussion of current surgical management strategies.

Main Results:

• Subtalar joint kinematics are intrinsically linked to its stability, influenced by both intrinsic and extrinsic ligaments.
• Accurate diagnosis requires a thorough understanding of clinical signs and appropriate radiographic interpretation.
• Evidence supports specific radiographic modalities for assessing subtalar instability.

Conclusions:

• Subtalar instability requires careful clinical evaluation and appropriate diagnostic imaging.
• Understanding subtalar biomechanics is key to diagnosing and managing this condition.
• Surgical options are available and require informed patient decision-making based on current evidence.
