Tarsal tendonitis is a nerve disorder that is caused by compression of the posterior tibial nerve that runs through the tarsal tunnel.
The Tarsal Tunnel is a narrow space on the inside of the ankle through which several nerves, arteries, veins and tendons travel though. It is covered externally by a ligament called the flexor retinaculum that connects the tibia (shin bone) to the calcaneus (heel bone).
Causes of Tarsal Tendonitis
Anything that narrows the tarsal tunnel and compresses the posterior tibial nerve can lead to tarsal tendonitis.
This Includes:
- Foot trauma such as falling or inward collapse of ankle
- Pronation
- Tendonitis – specifically of the flexor retinaculum
- Ganglion Cyst
- Varicose Veins
- Swollen Tendons
- Bone Spurs
- Flat Feet
- Nerve compression due to swelling caused by diabetes or arthritis
