What is the procedure name for a cock-up deformity of the 5th digit?

• A. Brandes procedure
• B. Keller procedure
• C. Ruiz-Mora procedure
• D. Suction curettage

Answer: (C)

The key idea is recognizing the specific operation described for correcting a cock-up deformity of the little toe. A cock-up deformity of the fifth toe is a fixed misalignment of the toe at the toe joint caused by soft-tissue contracture and subtle bone misalignment, which makes the toe ride up in the shoe. The Ruiz-Mora procedure is the operation historically described for correcting this exact issue, addressing both the bony alignment and the surrounding soft tissues to bring the toe back into a functional, properly aligned position under the shoe. That targeted fit is why it is the best choice for this deformity. The other named procedures are used for different conditions: Brandes and Keller relate to other toes or joints, and suction curettage is unrelated to toe deformities.
