Fractures of the Surgical Neck and Upper End ofthe Shaft of the Humerus.—For practical purposes thefractures of the surgical neck and fractures of the upperend of the shaft of the humerus maybe understood tomean fractures of the upper third of the shaft. Thesefractures are the most common ones met with in sub- Fractures of the Humerus, 03.

Ifthe fracture is immediately below the tuberosities thedifficulty will be in preventing the scapular musclesrotating the upper fragment outward. The lowerfragment, though drawn upward and inward for somedistance, as a rule occasions very little difficulty afterit has been thoroughly reduced. Fractures lowerdown between the attachments of the latissimus dorsi,the greater pectoral, and the deltoid are difficultsometimes also, on account of rotation and the tiltingupward of the fragment. The accompanying photo-graph No. 6 shows a fracture at this point, and it gavemuch trouble in the management of the upper frag-ments on account of the almost tetanic contractionof the external rotators and the pectoral muscles. In reducing these fractures after extension in theline of deform
