Tarsal Tunnel Syndrome

Tarsal tunnel syndrome

Tarsal tunnel syndromeTarsal tunnel syndrome is compression of a nerve (posterior tibial nerve) around the inside (medial) aspect of the ankle. It is also possible to compress other nerves in the ankle complex, although tarsal tunnel syndrome caused by compression of the posterior tibial nerve, is most common.

Tarsal tunnel syndrome often results in numbness in the ball of the foot and discomfort around the ankle complex.

Tarsal tunnel syndrome is caused by conditions which are likely to compress the nerve as it passes through the foot and ankle, such as scar tissue formation or arthritis. However, foot posture plays a significant role in nerve compressions, in particular the over pronated foot (flat foot, low arches, pes planus) has been shown to be associated with tarsal tunnel syndrome.

Diagnosis of tarsal tunnel syndrome can be from a good clinical examination.

If a biomechanical assessment shows the patient to have an over pronated foot (pes planus, flat feet or low arches). Then foot orthotics should be prescribed to correct the foot pronation and reduce nerve compression association with tarsal tunnel syndrome.

The Foot and Leg Clinic practice a very specific foot mobilisation technique which works well to correct foot posture for some patient not suited to wearing foot orthotics.
