Lateral and Medial Ankle Ligaments

Lateral Ligaments

Deltoid Ligament Complex 

Deep Components (2)

1. ATTL -- attached to anterior colliculus of MM - thin

2. PTTL -- attached to posterior colliculus of MM (fan shaped, striated(cf AITFL), lower 2/3's often bright)

Superficial Components (3)

1. TNavL

2. TSpringL - most important - coronal plane best

3. TCalcL

All blend with Superomedial component of Spring Ligament

Spring (Calcaneonavicular) Ligament

3 Components:

1. Superomedial CNL - most important -- abN if >5mm

2. Medioplantar oblique

3. Inferopalntar longitudinal - as thick as little finger

Periosteal apposition -- new periosteal bone superficial to cortex. Sign of chronic injury. Best on axial. With or without ossicles
