Pathologic Conditions of the Shoulder.  —In 1943 there were a number of papers which increased knowledge of the pathologic features of certain lesions about the shoulder.Wilson²⁰⁴ reviews the pathologic conditions of the tendinous attachments about the shoulder, particularly calcification and degeneration of the tendons. This paper gives a complete bibliography.Wilson and Duff,²⁰⁵ in a later paper, studied the gross and microscopic pathologic features of both shoulders in 90 adult bodies at autopsy and in 35 cadavers in the dissection room. All but 17 of the bodies were over 30 years of age. Complete rupture of the supraspinatus tendon was found in 9 of 34 cadavers.
