Hallux Abducto Valgus (Bunions)

Definition:
A valgus deviation of the hallux commonly associated with an exostosis on the first metatarso-phalangeal joint.

Symptoms:
When irritated by tight or ill-fitting shoes, bunions can become red and swollen.

Biomechanical Aetiology:
Bunions are most commonly caused by forefoot adductus and excess pronation of the subtalar joint. Some bunions are caused by arthritis or trauma. Due to excessive pronation, forces load the medial forefoot area. This increased adductory load on the 1st metatarsal shaft causes rotation of the shaft, which then requires the hallux (big toe) to compensate by abducting. Feet that have short 1st metatarsals or hyper mobility are more susceptible to this condition.

Treatment:
Foot orthotics control excess pronation (although not forefoot adductus) thus reducing load on the medial forefoot area and reducing valgus deviation of the hallux. Sometimes surgery may be indicated. Orthotic treatment post operatively should always be a consideration.

Hallux Valgus Sock:
The HV sock is a made to measure Polycotton Lycra sock (Class 1) medical device that has been designed as a full contact dynamic orthosis. This sock is recommended as a stand-alone garment where no rigid support is required. It can be used in the early management of Hallux Valgus deformity to defer surgical intervention and also in the post-operative management to ensure a successful surgical outcome and enhance functional potential post-surgery.

Features:
A full contact dynamic compression Lycra ankle sock medial reinforcement panel to correct/maintain great toe alignment. Early management of developing Hallux Valgus deformity. Post-operative management to maintain correction of Hallux Valgus deformity. Post-operative scar management in conjunction with silicone gel as a softening agent.
