What Is a Lapidus Bunionectomy?
A Lapidus bunionectomy is a surgical procedure used to treat a severe bunion deformity. A bunion is a bony bump that forms at the base of the big toe, causing the great toe to deviate toward the second toe and shift the entire foot alignment. In some cases, this deviation can be so severe that it affects the alignment of the entire foot.
The Lapidus bunionectomy is designed to realign the bones in the foot and correct the underlying structural deformity at the center of its angular rotation that is causing the bunion formation. To achieve this, the decision is made to fuse the motion of the base of the first metatarsal bone and the medial cuneiform.
During the procedure, an incision is made on the top of the foot and the first metatarsal bone is separated from the midfoot bones. The surgeon then realigns the bone and secures it with screws and a plate. The Lapidus procedure may be recommended for patients who have a severe bunion deformity, a hypermobile or unstable first metatarsal bone, or who have failed to achieve relief with other conservative treatments.
As with any surgical procedure, there are risks associated with a Lapidus bunionectomy, including infection, numbness, bleeding, possible nerve damage, and poor wound healing. Patients should discuss the potential risks and benefits of the procedure with their doctor to determine if it is the right treatment option for them.
