1859.] Divisions for the Cure of Deformities. 787The Reparative Process in Human Tendons after SubcutaneousDivisions for tlie Cure of Deformities.W. Adams, Esq., read before the Royal <strong>Medical</strong> <strong>and</strong> ChirurgicalSociety (June 28) a paper on this subject, illustrated by aseries of specimens <strong>and</strong> drawings from fifteen post-mortem examinations.Specimens of reunited tendons after division wereexhibited from ten cases, <strong>and</strong> also drawings, made by Ford, ofthe recent appearances in thirteen cases, at periods between fourdays <strong>and</strong> three years after the operations. These specimens hadbeen collected by Mr. Adams during the last eight years, <strong>and</strong>were principally from patients operated upon at the Royal OrthopaedicHospital ; but for two specimens he was indebted toMr. Erichsen <strong>and</strong> Mr. Curling. After alluding to our presentscanty information on the subject, <strong>and</strong> describing the recent appearancesin fifteen cases, the author gave a general summary ofthe reparative process, describing—1st. The immediate resultsof the operation. 2dly. The commencement <strong>and</strong> nature of thereparative process. 3dly. The general appearance <strong>and</strong> structureof the newly-formed connective tissue, or new tendon. And4thly. The junction of the new with the old tendon. This wasfollowed by an account of the circumstances which may interferewith the perfection of the reparative process, or entirelyprevent it, so that non-union of the divided tendon may result.Complete failure of union had been witnessed by the authoronly in the posterior tibial tendon, but it appeared that there isconsiderable risk of such an occurrence whenever tendons aredivided in or near to dense tubular sheaths. It was shown thatimperfect union might result either from some constitutional defectin the reparative powers of the patient, or from injudiciousafter-treatment in a variety of ways, but principally from tooearly <strong>and</strong> too rapid mechanical extension. The conclusionswhich the author considered to be established by the above seriesof cases were arranged under nine different heads. It wasstated that tendon is one of the few structures of the body capableof reproduction or regeneration, <strong>and</strong> that the newly -formedtissue acquires within a few months of its formation the structuralcharacters of the old tendon so perfectly, as that, under themicroscope, it is with difficulty distinguishable from it; but itdoes not acquire through its substance the uniformly opaque,pearly lustre of old tendon ; in the mass it retains a greyishtranslucent appearance, so that the recent section affords an easymethod of distinguishing the new from the old tendon. Thegreatest length of perfectly formed new tendon which the authorhad seen was two inches <strong>and</strong> a quarter, <strong>and</strong> this was in thetendo-Achillis of an adult, a year <strong>and</strong> a half after it had beendivided by Mr. Curling. That the process by which new ten-
