Nonunion of an Isolated Cuboid Fracture
A Case Report
Nonunion of an isolated undisplaced cuboid fracture is unusual. We report a case of symptomatic nonunion of an isolated cuboid fracture after nonoperative treatment. Fracture union was achieved with surgery, and the patient returned to full activities. (J Am Podiatr Med Assoc 103(3): 233–235, 2013)
Background:
Magnetic resonance imaging (MRI) and ultrasonography are used widely for the diagnosis of Morton’s neuroma. The aim of this study was to assess the accuracy of these two modalities as diagnostic tools in Morton’s neuroma.
Methods:
Fifty feet of 47 consecutive patients (39 women and 8 men; mean age, 46 years; age range, 36–64 years) who presented between January 1, 2005, and June 30, 2008, were included in the study. Twenty-five feet were investigated with ultrasonography and 25 with MRI. Morton’s neuroma was confirmed surgically and histologically in all of the patients. A Student unpaired t test was applied.
Results:
Twenty-two MRIs were diagnostic (sensitivity, 88%). Three patients with negative MRI findings underwent ultrasonography and were found to have a neuroma smaller than 5 mm. Twenty-four ultrasound scans demonstrated the neuroma (sensitivity, 96%), with five neuromas being smaller than 5 mm.
Conclusions:
Ultrasonography has a slightly higher sensitivity in the diagnosis of Morton’s neuroma, particularly of neuromas smaller than 5 mm, and should be the preferred imaging modality in suspected cases, and MRI should be reserved for cases with equivocal diagnosis.

Tuberosity fractures of the fifth metatarsal are common. The majority of these fractures are treated nonoperatively with good outcome. Surgery is indicated for nonunions, delayed unions, comminuted fractures, and displaced fractures. The surgical modalities include screw fixation, suture anchor fixation, Kirschner wires, tension band wiring, and locking plates. We report a case of a symptomatic nonunion of a displaced fracture of the tuberosity of the fifth metatarsal in a young patient treated with a tension band suture fixation that to our knowledge has not been described before.
