When the thoracic cavity in 510, 893 persons have been examined by means of small-framed roentgenofluerography under roentgenographic control, three cases with articulations in the middle of the first rib have been revealed: 2 cases unilateral and 1 case bilateral. Similar changes have been described by some authors using various names: joint, pseudoarthrosis, callus, fractures with various consolidations, disturbances in the course of the rib. In our roentgenogram: at the right--the posterior part of the first rib gets into the anterior part fork, at the left--the anterior part laterally, and the posterior part medially become conically narrowed; both junctions have light (cartilaginous) sheets and are regarded as synchondroses. It is important to keep in mind the possibility of existence of the connections in the middle of the first ribs in order to differentiate anomalies and pathological changes.
当采用小型X线荧光摄影术在X线控制下对510893人的胸腔进行检查时，发现了3例第一肋中部存在关节的情况：2例为单侧，1例为双侧。一些作者用不同的名称描述过类似的变化：关节、假关节、骨痂、伴有各种骨痂形成的骨折、肋骨走行紊乱。在我们的X线片上：右侧——第一肋后部进入前部的叉状结构；左侧——前部向外侧、后部向内侧呈锥形变窄；两个连接处均有透亮（软骨样）薄片，被视为软骨结合。为了鉴别异常和病理改变，必须牢记第一肋中部存在连接的可能性。
