Severe Talonavicular Osteoarthritis After a Neglected Navicular Stress Fracture: A Case Report.

CASE: A 17-year-old high school rugby player complained of right midfoot pain for 18 months. Radiographs showed severe osteoarthritic changes in the right talonavicular joint. A navicular fracture, talonavicular joint narrowing, a talar head cyst, and proximal navicular fragmentation were detected on computed tomography (CT). The patient underwent removal of the osteochondral fragments and fracture reduction and returned to rugby 8 months postoperatively. CT showed a remodeling of the talonavicular joint 2 years postoperatively.

CONCLUSION

In a young athlete, reconstruction of the talonavicular joint should be attempted before joint fusion, even if the joint shows signs of secondary osteoarthritis.
