Osteoid osteoma of the cuneiform bone is an exceedingly rare and easily missed cause of foot pain. The uncharacteristic and nonspecific radiographs of such intra‐articular osteoid osteoma further increase difficulty in making the diagnosis. To date, there has been no description of intra‐articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration in any published literatures. We present a case of intra‐articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration, who underwent curettage, allograft bone graft, and navicular‐cuneiform arthrodesis. The patient presented with radiographic bone union, full motor function recovery and pain‐free at the 22‐month follow‐up. This report adds to the existing literature. Intra‐articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration is an exceedingly rare and easily missed cause of foot pain. It proves a complicated and challenging task to identify intra‐articular osteoid osteoma. Clinicians should be particularly careful not to exclude the possibility of arthritis and, thus, vigilant when choosing the surgical option.
In this work, we report a patient with an intra‐articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration, who underwent curettage, allograft bone graft, and navicular‐cuneiform arthrodesis. The patient presented with radiographic bone union, full motor function recovery and pain‐free at the 22‐month follow‐up. Intra‐articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration is an exceedingly rare and easily missed cause of foot pain. It proves a complicated and challenging task to identify intra‐articular osteoid osteoma. Our work cautions clinicians against overlooking the possibility of arthritis caused by intra‐articular osteoid osteoma.
