BUNIONS Hallux Abducto Valgus—HAV
Bunions (Hallux Abducto Valgus—HAV)
Bunions -HAV are a change in the alignment of the bones in the first ray this produces a bony growth on the side of the 1st -big toe joint. This is called Hallux Abducto Valgus (HAV) commonly known as a bunion.
Bunions can have a number of causes including:
- hereditary disposition, genetics
- loose ligaments hypermobility
- poor footwear
- inflammatory arthritis
- over pronation of the feet.
Bunions -HAV can cause pain when walking and movement of the hallux (big toe). This pain is due to degeneration of the cartilage of the joint (osteo arthritis) that occurs during the formation of the bunion.
Long standing bunions -HAV can also cause the 2nd toe to retract and dislocate. This can lead to the formation of corns and calluses under the ball of the foot which can become a painful part of the foot and need regular podiatric treatment.
A podiatrist will assess your foot and identify the severity of your bunion.
The treatment plan will depend on the severity.
Minor deformities are predominantly caused by over pronation of the feet and the pain caused by the deformity can be decreased and further joint degeneration can be reduced with the use of orthotics and night splints.
Major deformities can require surgery to restore the alignment and function of the 1st MTPJ (big toe joint).
Post surgical orthotics are required to slow and prevent any recurrence of the bunion and stabilise the joint.
Any questions please feel free to ask the podiatrist, who will be happy to help you.
