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
