Clinically, if a patient’s dorsum of the foot appears to bulge after an external force, and there is significant subcutaneous bruising, localized pressure pain, and abnormal movement can be palpated, a metatarsal fracture is diagnosed. If the patient has an obvious subcutaneous bruise, local pressure pain, and abnormal activity can be palpated, then a metatarsal fracture has occurred, and an x-ray of the foot bone can be taken to make a clear diagnosis. Most of the treatment can be conservative, the patient can be instructed to rest in bed, elevate the affected limb, and give a brace for fixation to prevent displacement of the fracture end, and also instruct the patient to take oral bone grafting medication to promote early healing of the fracture site. In addition, if the patient’s blood circulation in the lower extremity is affected by prolonged standing or prolonged sitting or squatting, the veins in the dorsal part of the foot may become obstructed and may bulge. Therefore, patients who have this condition should consult a doctor in time and be able to alleviate this phenomenon with proper treatment.
