What distinguishes a McBride bunionectomy from a Modified McBride bunionectomy?

• A. Presence of fibular sesamoidectomy
• B. Implant use
• C. Incision length
• D. Post-operative recovery time

Answer: (A)

The distinction between a McBride bunionectomy and a Modified McBride bunionectomy primarily revolves around the surgical techniques and the specific structures addressed during the procedure. In a standard McBride bunionectomy, the procedure includes the removal of the fibular sesamoid. This is a crucial aspect because the removal of the fibular sesamoid can directly impact the alignment of the great toe and the function of the metatarsophalangeal joint. On the other hand, the Modified McBride bunionectomy typically involves a more conservative approach where the fibular sesamoid is not routinely removed, depending on the specific case. This modification is aimed at preserving more of the surrounding anatomy and maintaining stability in the joint. The other options—such as the use of implants, incision length, and post-operative recovery time—do not effectively differentiate these two procedures. While modifications in technique may lead to variations in these areas, the defining feature that sets apart these two surgeries is the presence or absence of fibular sesamoidectomy. Understanding this key difference helps inform surgical choices related to bunion deformities and their correction.
