A Mrs. Hunn informed me that when she was twenty-two yearsold she had a convulsion, and that her attendants, in trying to holdher upon her bed, actually pulled the shoulder out of joint. Afterthe first accident the dislocation was not repeated for four years, butsince then it had occurred from very slight causes many times. Shewas in the habit of reducing it herself by placing a ball in the axillaand using the arm as a lever. Dr. Lehman reports the case of a sailor on board an American brig,who was subject to a dislocation into the axilla from very slight causes,and especially if he bent his body far over to raise anything. Hecould also, by pulling horizontally, remove the head of the bone fromits socket. It was reduced easily, and he experienced no pain eitherin the reduction or dislocation, nor indeed, during the 1 Lehman, Amer. Journ. Med. Sci., vol. i. p. 242, 1828. DISLOCATION OF THE SHOULDER DOWNWARDS. 535. Dislocation of the shoulder downwards into the ax-illa. (Subglenoid.) Pathology.—In this accident the head of the bone is made to pressagainst the capsule below and immediately in front of the longhead of the triceps, until the p. 22Q capsule gives way, and con-tinuing to descend in the samedirection it is finally arrestedby the triangular surface of theinferior edge of the scapula im-mediately below the glenoidfossa. Owing to the pressureof the tendon of the triceps be-hind, it occupies a position alsoa little in advance of the centreof this triangle, or rather uponits anterior edge, so that itrests more or less upon thebelly of the subscapularis mus-cle. The capsule is generally tornquite extensively, especially be-low and in front; and, contraryto what has been affirmed bySir Astley Cooper, the tendonof the long head of the biceps is often broken asunder or detachedcompletely from its insertion; the supra-spinatus muscle is s
