are best. Subcutaneous injections of Lugol's solution, in several 

 points, over the joint is a good method of applying counterirritation 

 and leaves no unsightly blemish. 



Describe cold abscess of the shoulder. Give cause and treatment. 



A sharply defined, slightly painful tumor, lying in or below 

 the levator humeri muscle as it passes over the shoulder- joint. The 

 skin is sound and moveable and the thick, hard wall of the tumor 

 may show a point of fluctuation (pus) . 



Cause: Infection following bruising by an ill-fitting collar on 

 a patient doing heavy draft work. 



Treatment: Open the abscess, curette the cavity or cauterize 

 with a white-hot iron. Dress the wound daily with antiseptics. 

 If the growth is extensive, it may be necessary to remove some or all 

 of the new-formed tissue. 



Give cause, symptoms and treatment of paralysis of the suprascapular 

 nerve. 



Cause: Violent backward movements of the shoulder or leg, 

 causing overstretching of the nerve. Bruises to the nerve by blows, 

 collar, etc. 



Symptoms: Scapula and humerus are jerked away from the 

 wall of the thorax when weight is placed on the affected leg. 

 Atrophy of the paralyzed muscles occurs later. The atrophy is most 

 marked in the infra- and supraspinati and the two teres muscles. 

 It is noticeable by the apparent increased projection of the scapular 

 spine, and is referred to by laymen as "sweeney." 



Treatment: Massage and counterirritants such as subcutaneous 

 injections of Lugol's solution. Usually requires 6 to 8 weeks and 

 often months to effect a cure. Some cases never recover. 



Describe dislocation of the scapulohumeral articulation. 



It is caused by excessive movement of the joint, and appears as 

 a sudden lameness and difficulty in moving the joint. Passive move- 

 ment of the joint is interfered with by the swelling and tenderness. 

 Treatment should be directed to immediate reduction of the luxation. 

 Apply cold compresses and rest the patient as long as lameness 

 exists. 



Give the etiology and the treatment of shoe-boil (fibrous growth). 



Etiology : Bruises of the elbow in lying and arising. Pressure 

 from the shoe when recumbent is often cited as a cause, but is 

 undoubtedly a minor consideration. 



Treatment : Operative removal with the patient under a general 

 anaesthetic.
