Arthodesis is an open surgical procedure in which bones are fused together to relieve the intractable joint pain caused by degenerative arthritis or fractures that cannot be treated with joint debridement, ligament reconstruction or joint replacement.

Arthrodesis of the DIP Joint — the distal knuckle — is indicated when chronically painful joint deterioration has occurred, usually due to injury or Osteoarthritis. Arthrodesis is generally preferred to DIP joint replacement in the case of active patients. The finger is opened, the two abutting phalangeal bones have their arthritic surfaces trimmed, and then they are fused together using wires or screws. Recovery includes splinting until the bone heals.

Arthrodesis of the PIP Joint — the middle knuckle — is indicated when chronically painful joint deterioration has occurred, usually due to injury or Osteoarthritis. The finger is opened, the two abutting phalangeal bones have their arthritic surfaces trimmed, and then they are fused together using wires or screws. Recovery includes splinting until the bone heals.
