Abstract

Background

Checkrein deformity is an uncommon disease with a well-described etiology. It is characterized by a dynamic deformity of the hallux or great toe. We report two cases of checkrein deformity due a fibular graft harvesting in two patients with a mandibular bone defect secondary to an oral cancer treatment.

Case report

We report two young patients with mandibular cancers that had been treated several years before our visit and were currently free of disease. The patients had a mandibular bone defect due to the maxillofacial treatment, solved with a free fibular graft. The current complaint was a great toe deformity that caused pain and made them walk with difficulties. Diagnosis was a checkrein deformity, and after a surgical release of the flexor hallucis longus tendon, both cases returned to normal activities with no walking limitations.

Conclusion

Our cases highlight that an accurate patient examination is warranted following these reconstructions as many of them can be misdiagnosed, and a relatively simple surgery can improve the patients’ limitations.
