Hyperostosis was most extensive at segments C3-C5 causing stenosis of the pharyngeal lumen at the level of the larynx (Fig. 1).
CT of the right shoulder in a coronary plane. Hyperostosis is present at the medial side of the humeral head, as well as at the humeral insertion of the rotator cuff.

CT of the right shoulder showed extensive osseous proliferation of the medial humeral head reducing the articular space of the glenohumeral joint, as well as calcification of the rotator cuff (Fig. 2).
CT of the left ankle in a coronary plane. Ossification is present in the deltoid ligament. The tibiotalar and talocalcaneal joints show Kellgren grade 4 arthrosis.

In the left ankle, the CT scan revealed ossification of the deltoid ligament, and Kellgren grade 4 arthrosis of the tibiotalar and talocalcaneal joints (Fig. 3).   
CT of the cervical spine in a sagittal view. Osteophytes from C3 to C5 are removed. Sagittal alignment of the spine is preserved.

A control CT examination showed successful removal of hyperostosis from segments C3 to C5 with intact vertebrae and proper configuration of the cervical lordosis without signs of instability (Fig. 4).
