Hallux Valgus

Hallux Valgus - Commonly known as a bunion, this is a complex deformity affecting the big toe, the first metatarsal and the metatarsophalangeal joint.

Bunion~Causes

In this deformity, the big toe is abducted with certain rotation (valgus) in the frontal plane, while the first metatarsal is adducted rotating in varus, creating an articular incongruity, resulting in the dislocation of the first metatarsophalangeal joint and affecting other structures and ligaments, the joint capsule and both the intrinsic and extrinsic musculature. It can appear as a result of certain factors, such as abnormal development due to a pathomechanical deficit, wearing inappropriate footwear, pregnancy and menopause, and arthrosis, mainly affecting women. Today, it is considered a multicausal disorder in which genetics, footwear, hormonal and other factors may be present.

Hallux Valgus~Symptoms

Bone deformity with axial deviation of the first metatarsophalangeal joint. Pain due to pressure and/or friction caused by footwear. Inflammation of soft tissue due to the bone deformity, accompanied by deformities such as hammertoe and claw toe in the adjacent toes.

Bunion~Orthotic Treatment

Preventative or conservative treatment by means of corrective splints for day and/or nighttime use can prevent the progression of the deformity when its onset and clinical manifestations, such as pain or signs of arthrosis, become evident. In the event of requiring surgery, splints, together with specific plantar orthoses, are very useful to ensure that the surgical correction is maintained. Plantar orthoses can improve the load distribution of the big toe and reduce pain in static and dynamic activities. Silicone or gel protectors used for exostosis can relieve pain when wearing shoes. In addition, post-surgery shoes can help patients to walk and stand while wearing a postoperative dressing during recovery.
