Dr. L. A. Stimson1 described a method of reducing recent shoulder and hip dislocations, which he used with very gratifying results. His method appealed to me as being scientific and practical; hence, I have made use of the principle in all recent cases of dislocation of those parts coming under my care since his article was published. The results were so satisfactory that I feel justified in noting them.
The principle on which reduction of dislocations of the shoulder by continuous traction depends, is that the muscles are relaxed and rendered passive, thus offering no resistance to the movements of the humerus. There remains, then, only the ligaments and the atmospheric pressure to prevent reduction. The ligaments of the shoulder are so arranged that they offer no resistance to it and the looseness of the capsule is so great that the arm will fall about an inch from the scapula
