Syndesmology

The anterior talofibular ligament is the most frequently injured ligament in inversion ankle sprains due to its location and role in stabilizing the lateral aspect of the ankle.

Forced hyperextension, often combined with abduction, commonly injures the ulnar collateral ligament of the thumb, known as “skier’s thumb.”

The anterior cruciate ligament (ACL) is responsible for preventing anterior translation of the tibia relative to the femur. Damage to the ACL can cause knee instability, especially during activities involving quick directional changes.

The interosseous membrane plays a significant role in stabilizing the radius and ulna during pronation and supination movements.

The ulnar collateral ligament of the wrist is commonly stressed with forceful extension and ulnar deviation, particularly in repetitive sports like tennis.

The ligamentum flavum connects adjacent laminae and resists excessive flexion, contributing to the stability of the spine during bending movements.

Tenderness in the anatomical snuffbox is often associated with a scaphoid fracture. The scapholunate ligament is critical in stabilizing the scaphoid bone.

Widening of the AC joint and superior displacement of the clavicle are typically due to rupture of both the acromioclavicular ligament and the coracoclavicular ligament, particularly in more severe shoulder separations.

The lateral collateral ligament (LCL) resists varus forces on the knee. Damage to this ligament can cause increased lateral knee laxity.

The inferior glenohumeral ligament complex is often torn or stretched in anterior shoulder dislocations, as it provides the primary restraint against anterior translation, especially in the abducted and externally rotated position.
