When the fragment has suffered one of the rarer displacements byrotation it is generally impossible to restore it to place without anoperation. In three such cases I opened the joint by an incision on theouter side and, with considerable difficulty in two, turned the fragmentback into place and obtained a good result. Kocher twice excised thefragment under such circumstances, and reports a satisfactory result;both were old cases, and one of mine was two months old. In two old cases, one of them with displacement of the fragment 256 FRACTURES. downward and inward and partial dislocation of the ulna inward, theother with displacement upward and backward, I detached the frag- Fig. Fracture of external condyle; late result.

These fractures are commonly caused by great violence, and conse-quently are often compound, either by the direct action of the violenceupon the skin or from within outward by the sharp end of one of thefragments. In many the main line of fracture is the same as in supracondyloidfracture, with an additional line passing down into the joint betweenthe condyles; in the others the variations in the form and extent of thefracture and the degree of displacement are very great, the essentialfeatures being the separation of both condyles from the shaft and fromeach other, the variations appearing in the number and position of thefragments and lines of fracture. When the fracture between the con-dyles is a mere fiss
