Historical.—Beyond a passage ascribed to Hippocrates, but of very doubtful authenticity, and slight allusions in the works of Celsus and Paulus Ægineta, the ancients give us no information whatever on this subject.

Hippocrates says,—"Complete resections of bones in the neighbourhood of joints both in the foot, in the hand, in the tibia up to the malleoli, and in the ulna at its junction with the hand, and in many other places, are safe operations, if that fatal syncope does not at once occur, and continued fever does not attack the patient on the fourth day."

Celsus and Ægineta both advise the removal of protruding ends of bone in compound dislocations, but without giving any cases.

From the days of these classic fathers of Surgery, we have hardly an indication of any attention whatever having been paid to their hints till quite within the last hundred years.

The first distinct publication on the subject was by Henry Park of Liverpool, in a letter to Percival Pott in 1783. He proposed the removal of the articulating extremities of diseased elbow and knee-joints to obtain cures. He says he was led to this by its having been the invariable custom, for more than thirty years, at the Liverpool Infirmary, to take off the protruded extremities of bones in cases of compound dislocation.

The chief credit, however, in practically elevating excisions into the catalogue of recognised surgical operations, is owing, British surgeons most cordially own, to two provincial surgeons of France, the Moreaus (father and son) of Bar-sur-Ornain. They took the lead in the most marked manner, having excised the shoulder in 1786, the wrist and elbow in 1794, knee and ankle in 1792, and had followed this up so well that, in 1803, the younger Moreau could boast, "the town has become in some sort the refuge of the unfortunate afflicted with carious joints, after they have tried all the means usually recommended by professional men, or have had recourse to empirical nostrums, or when amputation seemed to them the last resource."

Moreau's papers and cases, which, between 1786 and 1789, he frequently read to the French Academy, were, some violently opposed, others utterly neglected by his compatriots, and many of them lost and buried in the unpublished papers of that body.

And though diseased joints did not decline in frequency, and though injured ones were extremely numerous during these long years of European war, excisions were but rarely performed.

With the exception of the removal of head of humerus after gunshot injury, hardly any British, and but very few French, limbs were saved by excision taking the place of amputation.

The limbs that were saved by Percy by excision of the head of the humerus really owe their recovery and safety to the elder Moreau; for an operation of his, at which he was assisted by that distinguished military surgeon, gave the latter the hint, which he followed so successfully, that by 1795 he had performed it nineteen times, and had indoctrinated Sabatier, Larrey, and others, and elevated it into a recognised operation of military surgery.
