摘要The definition of the subscapular bursa (SSB) remains controversial.One researcher demonstrated that SSB was a separate pouch.[l] However,others believed that SSB was actually the superior subscapularis recess (SSR),which is an outpouching of the glenohumeral joint capsule.[4] Whether or not the SSB and SSR are two different bursae must be confirmed.Furthermore,the fluid in the SSR revealed in magnetic resonance (MR) imaging has been regarded as an indication for a diagnosis of frozen shoulder.[3] Considering that the SSB and SSR are two different structures with a close spatial relationship,recognition of the MR appearance of SSB might have important diagnostic implications.The purposes of this study were to describe the anatomy of the SSB using a three-dimensional (3D) visualization technique based on the Chinese visible human (CVH) and to explore the MR appearance of the SSB.
