En uno u otro caso se da lugar a un hueso accesorio, denominado Os
trigonum (OT) (Fig.
The mediolateral axis consists of the line between the centroid of the
trigonum spinae and glenoid cavity centroid.

Trigonum. Cyprus J Med Sci 2017; 2: 40-1
Caption: Figure 4: Lateral radiograph of right foot indicating mega os
trigonum.
(9-11) The radiographic features include varying degrees of epiphyseal involvement with enlargement of the epi-metaphyseal region, progressive joint narrowing, generalized platyspondyly, multiple intervertebral herniations, kyphoscoliosis, mega os
trigonum and bone destruction with aging.
This bony fragment could correspond to an os
trigonum. Interestingly, this bony structure was not identified on the prior MRI.
The coordinate system was constructed by identifying the center of the
trigonum on the medial border of the scapula, the distal-most point, and the geometric center of the glenoid.

The talus/os
trigonum synchondrosis appeared intact, although subchondral erosions were present along the articular margins (Figure 1).
