Turf toe is caused by trauma to the big toe as it hits the ground during sports and compresses the toe into the joint.
Post trauma, it can cause long term stiffness and pain on hyperflexion. This has become an increasingly common problem due to the rise in the use of synthetic pitches.
We highly recommend a biomechanical assessment with Gait analysis, alongside footwear education and/or orthotic therapy to reduce the symptoms.
