Proximal metatarsal osteotomies work well to achieve reliable deformity correction in patients with a large 1st-2nd intermetatarsal angle. They may help minimize rotation, shortening, and elevation of the metatarsal. A number of osteotomy techniques have been described, including Ludloff, Mau, proximal crescentic, proximal chevron, scarf, opening wedge, and closing wedge, among others.
The Proximal 1st Metatarsal Osteotomy Plate works with osteotomies where the proximal 1.5 cm of the 1st metatarsal is preserved to allow for placement of locking screws. This plate can be used alone or as an adjunct to screw fixation.
