Nonunion of a Stress Fracture at the Base of the Second Metatarsal in a Soccer Player Treated by Osteosynthesis with the Bridging Plate Fixation Technique

Abstract EN

Background.

A stress fracture of the second metatarsal base in soccer players is extremely rare.

In this case study, we report a nonunion of a stress fracture at the base of the second metatarsal in a female soccer player who had persistent pain despite continued conservative treatment, who then was treated with the bridging plate fixation technique.

Case Report.

A 19-year-old female college soccer player complained of pain on the dorsum of her right midfoot during a game without history of trauma and was conservatively treated for 6 months.

Radiographic examination showed an oblique fracture with small bone fragment at the proximal base of the second metatarsal and computed tomography demonstrated sclerotic change around the fracture site.

We diagnosed her with nonunion of a stress fracture at the base of the second metatarsal and performed operative treatments using autogenous cancellous iliac bone grafting and plate fixation bridging a second metatarsal and medial cuneiform with a locking plate.

At 4 months after the initial surgery, she was able to return to playing soccer at preinjury level without complications or pain.

Conclusion.

We report a rare case of nonunion of a stress fracture at the base of the second metatarsal in a female soccer player without underlying diseases.

Surgical treatment was applied, because the conservative treatment was ineffective for 6 months and led to nonunion.

The plate fixation technique bridging the second metatarsal and medial cuneiform was a useful option to attain the bone fusion for small fracture fragment for a treatment of nonunion of a stress fracture at the base of the second metatarsal.
