Talo-calcaneal joint
- joint space reduction (compare with the asymptomatic side)
- joint is bridged by soft tissue showing fibrillary echo pattern
- a cystic lesion (4 x 3 x 2 mm) is seen abutting joint line
- the neck of this lesion is seen extending into the talocalcaneal joint. The defect is seen in bridging fibrillary soft tissue.
Talus
- bony hypertrophic prominence on medial aspect abutting talocalcaneal joint
- it increases the distance between flexure digitorum tendon and neurovascular bundle in comparison to asymptomatic side
Posterior tibial nerve
- edema of medial branch of nerve at and just proximal to the talus
- this branch shows elevated course due to the hypertrophic bone of talus
- cross sectional area of the nerve is double (6 mm2) as compared to asymptomatic left side (3 mm2) at the same level
- lateral branch and calcaneal branch show normal echo pattern
Medial tendons
- normal echopattern
Vessels
- patent
