There are two treatment options for the first metatarsal fracture, which are conservative treatment and surgical treatment. If the fracture is well aligned and can meet the minimum functional repositioning criteria, and there is no rotational deformity or separation displacement, conservative treatment can be considered, with external fixation in plaster or polymer splinting, followed by elevation of the affected limb, dehydration treatment, and bone grafting and calcium supplementation medication. If the fracture is poorly aligned, there is no way to achieve the minimum functional repositioning standard, or if the fracture has separation and displacement, rotation and displacement, or large angular deformity, surgical reduction and internal fixation is required. The fracture is satisfactorily repositioned under direct vision and a relatively strong internal fixation, such as a Clinostat pin or a miniature metacarpal plate, is used.
