Bunions | Hallux Valgus
Hallux Valgus occurs when the normal balance of forces acting around the joints and tendons of the feet are disrupted. This eventually leads to joint instability, with the metatarsal gradually sitting at an angle to the foot. The toe is then forced inwards, with a bump (the bunion) forming as the tendons and other tissues around the toe react to the abnormal position.
Interestingly, bunions can also occur on the joint of your little toe (bunionette).
Causes of this abnormal balance of forces resulting in bunions include:
- High-heeled, ill-fitting shoes or those with points (eg ballet)
- Inherited foot type
- Foot injuries
- Conditions that affect the shape of the feet including:
Any work or activity that puts extra stress on your feet can also be a cause of bunions.
