What is Hallux Interphalangeus?
This deformity is similar to the appearance of Hallux Valgus (bunions). The big toe deviates towards the outside of the foot. The difference between the conditions is that in Hallux Interphalangeus, the deformity is at the smaller and more distal interphalangeal joint rather than at the metatarsophalangeal joint. The deformity is often a result of trauma, arthritis or genetics.
What are the symptoms of Hallux Interphalangeus?
Patients will notice a lateral deviation of the big toe. This can cause overcrowding of the lesser toes, callosities, pain and difficulty wearing certain footwear.
How is Hallux Interphalangeus diagnosed?
Clinical examination and X-rays will demonstrate the deformity but a good history from an expert Foot and Ankle specialist will normally identify the underlying cause.
How is Hallux Interphalangeus treated?
Footwear adaptation and splinting can improve the symptoms that the patient experiences. However, this will not correct the deformity definitively. Surgical correction can take the form of osteotomies to straighten the toe or fusion of the interphalangeal joint.
