    SECTION II. 2. A fracture of the condyle may sometimes arise from a counter-stroke, as when, in consequence of some external force being applied from before backwards, and from below upwards against the chin, this process is driven against the projecting rim of the glenoid ca- vity ; at other times it may be the effect of an imme- diate or direct stroke, as when a body in motion strikes with force against the region of the joint, and does vio* lence to that portion of the bone. 3. But in whatever manner the fracture may be pro- duced, it generally occurs in the slender part of the bone which supports the condyle, below the insertion of the pterygoideus externus. It is characterized by a pain more or less acute, necessarily accompanying the motions of the jaw; by a difficulty more or less considerable, in the performance of these motions ; by a crepitation, oftentimes distinct, when, in consequence of the angle of the jaw being pushed forward, or the jaw itself alternately depressed and elevated, the separat- ed surfaces rub against each other; by an inequality of surface sometimes perceptible directly over the fractured condyle; by the ease with which, on being pushed for- ward, it may be forced into the depression beneath the zygoma; and by its remaining stationary, during the movements of the lower jaw, from which it is separated. These signs, though generally characteristic, are sub- ject to an uncertainty proportioned to the swelling that occurs in the part. 4. In this accident a displacement is almost always produced by muscular action. The pterygoideus ex- ternus, being attached to the condyle, draws it forward
