The results of nerve grafting which apriori appears to be a logical procedure,cannot yet be appreciated, since regenera-tion is beset with difficulties and takes placebut slowly. What happens to this nervesegment deprived of all blood-supply andused as a scaffold ? J. Sicard has suggestedneuro-vascular auto-graftinghy transplantingthe segment of a neighbouring nerve whilepreserving a large pedicle of vascular andconnective tissue. m Fig. 28.—Nervegraft.(After ) This procedure would be applicable in all cases SURGICAL TREATMENT OF INJURIES 313. where there was a healthy sensory nerve in the neigh-bourhood. Lateral Notch. Preserve the Gontinaity.—The lateralnotch should be treated according toGossets method. Preserve the bridgeof nervous tissue, pare away slightlyall the wall of the notch, and suturethe two lips end to end (fig. 29). Crashing, Pseudo-continuity, Resec-tion.—When the nerve is very com-minuted, much torn, crushed, adherentto the neighbouring fibrous tissue, orimprisoned within a callus (as veryfrequently occurs in lesions of themusculo-spiral nerve), it often appearsat the site of lesion as a flattenedfibrous band situated between twoswelHngs on the nerve and of a greaterlength than the nerve-trunk itselfshould be. These cases are nearly always ex-amples of complete section of the nerve with pseudo-continuity, the tissues between the two swellingsconsisting of fibrous and muscular tissue only. Underthese conditions the only logical operation is resectionof this bridge of tissu
