Luxation, signifies the dislocation of any bone out of its natural articulation, so as to impede or destroy its proper motion. The general symptoms of this complaint are, inability to move the injured limb ; pain ; tension ; and deformity of the part affected : it is also frequently attended with inflam-. mation and fever. in the treatment of simple luxations, if the contiguous skin and muscles be much inflamed, leeches ought first to be applied, and the dislocated limb kept in the most' easy posture, before the reduction of the bone can be attempted ; because the stretching of a limb, while the surrounding muscles are in a state of inflammation, may-prove highly injurious : the upper part should likewise be held steady, while the surgeon is replacing the bone. And, as the contractile power of the muscles frequently resists every mechanical effort, they ought to be previously relaxed by emollient poultices or fomentations, in consequence of which the bone may be easily replaced.

After the operation, the limb must be kept in a relaxed state, and the bone supported with a bandage, till the parts have recovered their proper energy ; but, where any visible inflammation remains, it will again be requisite to apply leeches.

If dislocation be accompanied with a fracture near the joint, such injury must be allowed to heal previously to reducing the bone. Where, however, any tumor or collection of matter near the joint is the cause of luxation, this affection may be considered as incurable ; but, if it proceed from too great relaxation of the ligaments or tendons of the joint, the complaint has frequently, though gradually, been removed by supporting the limb with a proper bandage ; by the use of the cold bath, and by electricity. - During the whole period, between the setting-, and healing of a luxated bone, the patient must preserve the disordered part in a state of rest; subsist on mild but nutritious aliment ; and carefully avoid the influence of the depressing passions.
