The results of this experimental study suggest that scaffold-free 3D TEC made using cultured synovium-derived MSCs can be a new approach for the repair of epiphyseal injury. Clinical effectiveness of a scaffold-free 3D TEC for growth arrest remains to be determined.

Focal fibrocartilaginous dysplasia (FFCD) is a rare benign bone lesion, which mainly occurs in the proximal tibia. In the upper extremity, only 21 cases have been reported so far and 14 of these involved the ulna. We present an additional case of FFCD in the distal ulna that showed progressive bowing of the right forearm and the radial head dislocation. Resection of the abnormal tissue, osteotomy of the radius and ulna, and gradual lengthening of the ulna were performed. On the basis of the previously published data of 14 cases and our data, we have summarized the etiology, clinical features, natural history, and treatment of FFCD in the ulna.
