This is an accident which is frequently caused by violent muscular contraction; especially if, after illness or long inactivity, the muscles are subjected to sudden and severe exertion. "It occasionally happens," says Mr, Liston, "to gentlemen of mature years, who, forgetting these, join in the sports of youth as they were wont to do; suddenly they suppose that some one has inflicted a blow on the leg from behind, their dancing is arrested, the foot cannot be extended, and the nature of the case is evident to the most careless observer."

Treatment

The main point is to keep the injured muscle in a state of rest and relaxation, so that the broken ends may be kept close together, and remain so till they are firmly united. Pain and inflammation of the part must be counteracted by leeches, and cold or warm lotions or poultices. These are usually tedious cases, and it is sometimes many weeks before the patient can safely attempt to use the limb.
