A Case of Acute Prosthesis Migration after Femoral Head Replacement due to Osteomalacia by FGF23-Induced Tumor

الملخص EN

Fibroblast growth factor 23 (FGF23) was recently identified as an important factor involved in the development of hypophosphatemic rickets and osteomalacia.

We experienced a rare case of acute prosthesis migration after hemihip arthroplasty due to FGF23-induced tumor.

The patient underwent femoral head replacement because of femoral neck fracture, but prosthesis migration was occurred at 1 week after operation.

The patient took various examinations, and FGF23-induced tumor was found in his right wrist.

The tumor was resected, and he underwent total hip arthroplasty 8 month later.

Finally, he was able to obtain free gait without pain.
