What is arthrodesis for a hammertoe?

Short answer: Arthrodesis straightens and fuses the painful middle joint of a rigid hammertoe. It is generally the most structurally definitive option when the joint is fixed, unstable or unsuitable for a motion-preserving procedure.

The damaged joint surfaces are prepared, the toe is aligned and the bones are held while fusion develops. The treated joint no longer bends, but the purpose is a stable, plantigrade toe that fits footwear more comfortably.

Arthrodesis is usually considered after simpler options have been assessed. It may be combined with correction at the base of the toe if metatarsophalangeal instability is contributing.
