Electricity and massage constitute the most importantpart of the treatment. Paralysis of Individual Nerves of the Brachial Plexus. (a) Long Thoracic Nerve (from fifth and sixth cervical roots).—Itsupplies the serratus muscle. Etiology.—Injury or prolonged pressure on the neck (in carryingheavy weights on the shoulder), gunshot wounds of the neck, continuouselevation of the arm (as in plastering ceilings), infectious diseases (diph-theria, typhoid fever, grippe), finally exposure to cold—are the causes. Symptoms.—Pain may or may not precede the onset of paralysisof the serratus muscle. The function of the latter is to rotate the scapulawhen the arm is put forwards, also to hold the scapula against the Fig. 132.—Showing Positionor the Arm in Birth Palsy. DISEASES OF SPINAL NERVES 419 In case of paralysis of the muscle the arm cannot be raised above ahorizontal position and in the attempt to put the arm forwards the innerborder of the scapula becomes separated from the thorax (wing-like). The Course and Prognosis depend upon the cause. The diseaselasts many months. Traumatic cases are the most unpromising. Restof the arm (sling) is advisable. Massage and electricity should beinstituted as early as possible. (b) Supra-Scapular Nerve (from fifth, sixth, also fourth roots).—Itsupplies the supra- and infraspinatus muscles.
