    Fractures of the humerus, in the region of the joint, frequently implicate it, and are to be distiug-uished from dislocation by there not being- the chang-e in the normal relation of three tuberosities—viz., the ole- cranon, epicondyle, and epitrochlea. Almost any form of dislocation may exist, but the most common is that of both bones of the forearm backwards, the strengrth of the lateral ligaments being- a great obstacle to lateral displacement. The dislocations to which the articulations of the elbow-joint are liable are, in the first place, of both radius and ulna, backwards, outwards, inwards, for- wards ; of the radius only, forwards and backwards; and of the ulna only, backwards. The difficulties in the diagnosis of these several conditions are fre- quently enhanced from the complication with fracture or separation of the epiphyses, the union of which is as follows :—the outer condyle and both portions of the articulating portions of the humerus at the six- teenth or seventeenth year, the inner condyle at the eighteenth year, whilst the superior articular ex- tremities of the radius and ulna unite with their shafts at puherty. SCTEGICAL ANATOMY OF THE FOREAKM. Surface markinys.—The region of the forearm, or ante-brachial, may be described as lying between the lower margin of that assigned to the elbow and the first fold seen before the wrist-joint. In shape it is that of a flattened cone, which varies in form accord- ing as the limb is pronated or supinated, the round- ness of its lateral boundaries being due to the flexors and pronator teres on the inner, and the supinators and
