body-image was found. In the clock test she failed to read the time correctly with either hand and could not be persuaded to make the effort to set the hands of the clock. There was no evidence of dyspraxia in either hand. She was able to remove a paper match from the cover which she held in the opposite hand and strike it afire readily. She did this as easily with the left and right hands as before operation. She was able to write with either hand with eyes open or when blindfolded ( Fig. 2A ). She correctly held the pad in one hand and the pencil in the other. The

, convulsions or confusion. In addition to the patients, 25 hospital employees were subjected to the same tests; 17 of these were females, 8 were males. Though these subjects do not constitute a matched control group, the results obtained from this series helped in the evaluation of the data.

his head in a tussling match. He experienced sudden pain at the back of his head which radiated to the vertex. At first this pain would come in paroxysms but for the last year it had been almost continuous. Loss of hearing had been bilateral and progressive, existing for a number of years, the right ear being involved more than the left. Approximately one year before admission there was onset of progressive weakness of the right arm and leg so that, on admission, he had to drag the right leg in attempting to walk. Simultaneously there was noted a feeling of numbness

full restoration of normal function, as it existed prior to the injury, is wholly beyond attainment. Only statistically can one try to approach this goal by taking measures that will allow the maximum possible number of nerve fibers to restore connections of the old type or, at least, one functionally similar. The recommendation of some neurosurgeons to match the fascicular topography of the stumps in suturing as best as feasible, 173 thus seems to make good sense physiologically. It is partly invalidated by the practical difficulties of identifying the orientation

homologous nerve (sciatic nerve graft for repair of a gap in the sciatic nerve) taken, in fact, from the same level of the nerve. Thereby one can to some extent at least match fasciculi of the graft and the host stumps in a rough way. However, as an actual fact, much distortion of the internal relationships occurs within the graft as a result of its nerve fiber degeneration and fibrous proliferation so that the theoretical advantage is thereby largely negated. The use of single thin grafts for the repair of defects in the digital nerves is associated with satisfactory

Extensive Brain Wounds

Analysis of 159 Cases Occurring in a Series of 342 Penetrating War Wounds of the Brain

an entrance and an exit wound. The most common agent was that of a fairly large piece of high explosive shell fragment. During the passage through bone and brain it caused a great amount of local maceration of brain tissue. A marked degree of diffuse brain damage was present because of the powerful striking force. PATHOLOGY It is difficult to separate those instances of extensive brain damage from those of a lesser degree. A match-head sized missile may cause little local damage and yet, because of vital centers involved, mean death. A large missile

aqueduct and the 4th ventricle were not seen for obvious reasons, but the lateral ventricles, commonly, and the third ventricle, rarely, were involved. The missile was usually small, sometimes of match-head size. These constitute a group of wounds technically difficult to repair, but causing a minimal amount of ependymal damage and offering the best prognosis. The pathologic study of the brains suspected of harboring a ventricular wound was facilitated at necropsy by laying open the ventricular system by sagittal section of each cerebral hemisphere. Missiles entering

ends the bundle patterns can be compared and the holding tabs of nerve sheath placed so that corresponding end bundles will be brought into opposition during suture. Small matched mosquito clamps are then placed on the tabs exactly adjacent to the end surface of the cut nerve ( Fig. 2 ). The clamps are applied with handles away from the operator to be held by the first assistant. The two clamps are then rotated horizontally 180° ( Fig. 3 ), bringing the end surfaces of the nerve into accurate approximation ( Fig. 4 ). The assistant holds both clamps in one

The volage supply comes from a 4½ volt dry battery. The ratio arms P and Q consist of 150,000 ohm-½ watt carbon resistors, preferably a matched pair (obtainable at any radio supply store). This resistance level was chosen for the resistors since it closely approaches the average resistance of normal individuals and thus makes it possible to obtain a quick and accurate

. It is noteworthy that while measurements on one side of a specimen were usually matched by measurements of a similar magnitude on the opposite side, this was not invariably so. Substantial differences were rarely present between the two sides, especially in the anteroposterior direction. SUMMARY Significant variations in dimensions of the semilunar ganglion and its roots, of as much as 1 cm., especially in the anteroposterior direction, have been found in 32 fresh postmortem dissections. The points where the ganglion trifurcates into its roots may thus be
