It may remain as a separate ossicle in 7-14% of patients, and is often bilateral. Pain can also be caused by disruption of the cartilaginous synchondrosis between the os trigonum and the lateral talar& .2 (Jedi lateral dimension)cm..4 (craniocaudal dimension) x 0.... In this anomaly, the cuneiform bone is divided horizontally by a synchondrosis, partitioning the medial cuneiform into plantar and dorsal segments. It was tender on deep palpation. corticated bony ossicle . Mellado JM, Ramos A, Salvadó E, Camins A, Danús M, Saurí A.“There is a small corticated ossific density seen adjacent to the tip of the lateral malleolus which is most in keeping with an accessory ossicle or sequelae from old trauma.There was a palpable bony swelling that felt hard and fixed to the antero-inferior aspect of the lateral malleolus.One in which bone is replaced by cellular fibrous tissue which gradually matures with the formation of woven bone, lamellar bone ,or very dense amorphous mineralization. The site of partition should demonstrate smooth, well corticated margins, and the two portions of the bipartite cuneiform together are larger than the expected normal or fractured medial cuneiform.. 2003 Dec;13 Suppl 4:L164-77..... as small radiolucency and expands slowly; Calcification develops centrally as the lesion enlarges; Most become densely calcified; The lesion has a sharply defined margin often within radiolucent rim surrounded by a narrow zone of cortication.Cortication: Fractures have sharp, radiolucent, uncorticated lines, while bipartite sesamoids have two corticated fragments. The posterior surface of the os trigonum is non-articular but serves as a point of attachment for capsuloligamentous
