Tibial fracture arising from bone amyloidosis: A case study

Abstract

Background

Amyloidosis, a disease characterized by the deposition of abnormal proteins in various organs, leads to functional disorders. Here, we report the case of a 63-year-old man with AL amyloid deposition in the tibial shaft that resulted in a tibial fracture.

Case presentation

Amyloid bone cysts typically occur in the joints and vertebrae of patients undergoing hemodialysis; however, in this case, the patient was not undergoing dialysis, and the deposition site was the tibial shaft. We performed curettage and osteosynthesis using a plate, and satisfactory patient recovery was observed at a 1.5-year postoperative follow-up.

Conclusions

Amyloidosis may cause functional impairment due to amyloid deposits in multiple organs and other complications; therefore, systemic examination is necessary.
