An internal plate fixation device is provided for load bearing and non-load bearing fixation for the Mau-type osteotomy procedure for hallux valgus correction in the first metatarsal bone of the foot. The preferred example includes a set design plate having screw holes for attachment of the plate to the first metatarsal bone of the foot. Screw holes are located on the plate, including screw holes on top of the plate and screw holes at the ends of the plate. A temporary small holding wire hole is located in the plate to hold the plate to the bone temporarily. This plate allows both angled screw fixation of the Mau osteotomy and locking screw hole capability to ensure stability when fixating the Mau osteotomy.
