. The principles and practice of modern surgery . lts that haveensued from attempts at reduction at a later period ; the integuments andmuscles have been lacerated; abscess has formed, and been followed byanchylosis of the joint; nay, even the whole side has been palsied frominjury to the cervical vertebrae, and the axillary artery has been torn across. Injuries of the shoulder-joint are liable to be followed by various obsti-nate and intractable affections. Sometimes the deltoid muscle wastesaway, owing probably to injury of the circumflex nerve. Violent spasmsand neuralgic pains of the arms sometimes occur from injury to the othernerves; and there are some cases in which rupture or displacement of thelong tendon of the biceps is the source of continued impairment of motion;and, together with displacement of this tendon, the head of the humerushas been known to be partially dislocated upwards.* IV. Dislocation of the Elbow presents six varieties. Both radiusand ulna may be dislocated, (1) simply backwards; or, (2) backwards Fig. • Spo a paper by Mr. Stnnley on Rupture of t)io Biceps Tfndon. in tlic vol iii.; and rnsf> of [xirtiul dislocation of llic Ininicrus iijiwards, by Mr. Sodon, inMed Chir.

(4) The ulna by itselfmay be dislocated backwards ; — and the radius by itself either (5) back-wards, or (6) forwards. (1.) When both radius and ulna are dislocated backwards, the elbow isbent at a right angle, and is immovable; — the olecranon projects muchbehind ; — a hollow can be felt at each side of it, corresponding to thegreater sigmoid cavity ; — and the trochlea of the humerus forms a hardprotuberance in front. The coronoid process rests in that fossa of thehumerus which naturally contains the olecranon. (2.) In dislocation of both bones backwards and outwards, the coronoidprocess is thrown behind the external condyle; and in addition to the
