March fracture is the fracture of the distal third of one of the
third metatarsal bones of the foot.[1][2][3] It is a common cause of foot pain, especially when people suddenly increase their activities.[4]
Signs and symptoms
The onset is not dramatic. When the boot or
dorsal surface, a point of tenderness is found directly over the lesion. Radiography at this stage is negative, but the condition is diagnosed correctly by military surgeons without the aid of x-rays. In civil life, it is seldom diagnosed correctly for a week or two, when, because of lack of immobilization, there is an excessive deposit of callus (which may be palpable) around the fracture.[1]
Diagnosis
MRI study may help in diagnosis.[5]
Bone scans are positive early on. Dual energy X-ray absorptiometry is also helpful to rule out comorbid osteoporosis.[6]
Differential diagnosis
- Acute metatarsal fracture
- Hallux rigidus
- Jones fracture
- Sesamoidstress fracture
- Acute sesamoid fracture
- Proximal fifth metatarsal avulsion fracture[7]
Treatment
The first line treatment should be reduction of movements for 6 to 12 weeks. Wooden-soled shoes or a cast should be given for this purpose. In rare cases in which stress fracture occurs with a cavus foot, plantar fascia release may be appropriate.[6]
Occurrence
Lisfranc joints. This fracture always occurs following a prolonged stress or weight bearing, and the history of direct trauma is very rare. Consideration should always be given to osteoporosis and osteomalacia. Cavus feet are a risk factor for march fracture.[6]
