Juvenile HAV

The presence of HAV in children is uncommon in comparison to adults. It has been suggested to be inherited, is more common in females and can be exacerbated or caused by footwear. It can also result from inflammatory arthritis and from muscular imbalances within the foot. Radiologically all HAV cases vary substantially, this is partcularly apparent in the child or adolescent with the condition. This supports the genetic theory of aetiology.

Case 1: Hallux abduction is associated with metatarsal adduction affecting the first three metatarsals. No sesamoid drift is noted which indicates a joint which is still functional.	Case 2: Although only the first metatarsal is adducted the head of the metatarsal is rounded and unstable whilst severe sesamoid displacement is noted. A poorly functioning joint.
Case 3: The metatarsophalangeal joint is stable with little sesamoid change. The abduction is due to development of a high hallux interphalangeus angle. This joint is also relatively stable.
