A practical and systematic treatise on fractures and dislocations . g from the scapula to the humerus belowthe line of fracture, produce shortening. The symptoms are generally very evidentand not liable to be mistaken for the arm is rotated, the head of thehumerus remains motionless in the glenoidcavity. The mobility of the shaft or lovv^erfragment is marked, and crepitus is distinctwhen extension is made, or the broken ends ofbone are moved while in apposition. Frac-ture at the line of junction of the epiphysis,in young subjects, resembles true fracturethrough the surgical neck of the bone in oldsubjects. The only discoverable difference isa less marked crepitation in the cartilaginousseparation. Fracture through the surgical neck of thehumerus, in adults, is generally a half inch or more below theline where separation of the epiphysis occurs in the young. If the injury be not seen until the parts have become tender, and much swelling has supervened, fracturethrough the surgical neck will closely resemble dislocation of. Fracture through thesurgical neck of thehumerus. Of the Humerus. 121 the sliouldcr. However, in case of (lonl)t and uncertainty, thepatient may be put under the iiiHuence of chloroform, whenthe nature of the lesion can be determined. In case of frac-ture, the space beneath the acromion will be found filled withthe head of the bone; the humerus will not stay reduced, butslide towards the axillary space as soon as left to itself; andgreat mobility at the seat of injury will be observable. Allof these signs present unequivocal evidence of the existenceof fracture. From a consideration of the anatomy of the region, itwould seem that a fracture through the surgical neck of thebone could not take place without marked displacement anddeformity. In a small proportion of instances, however, there is no perceptible disjunction of thefragments, a state of appositionwhich is probably favored by theinterlocking of serrations in th
