electric power in bone plastic surgery Como Comprar Cialis Generico No Brasil even if we do not take Como Comprar Cialis Generico No Brasil into consideration the paramount advantage of the rotary cutting tools which produce automatic (machine) fits — for example, the twin saw, which not only produces the gutter but also removes the bone graft and thus ensures a perfect inlay ; or the dowel shaper whose cutter being exactly commen- surate with the corresponding drill, ensures the most accurate fit of a bone peg fashioned with the dowel shaper and inserted in a hole produced by the equiv- alent drill. I take a pardonable pride in having in- troduced into plastic bone surgery not only the use of electric power but also automatic machine tools whose field of usefulness has proved to be wider than the technic of bone grafting, although the range Fio. 2.— Details of motor bone clamp (hand driven).

The other letters are the same as in Fig. 2. of applicability of the latter has been thereby greatly increased. Disadvantages of the bone clamt's hitherto used.— (a) The arms of the old instruments were applied from below; in this new clamp they are applied through the incision directly from above. Applica- tion of the gripping jwrtion of the clamps hitherto manufactured required wide dissection and separa- tion of the soft tissues from the fragments in order to permit the clamps to be locked upon the bone from below (c. g.. the Lowman clampV This is undesirable if avoidable since it temporarily impedes the circulation in the bone in the region of the frag- ment ends on account of the separation of the over- May i8, 1918.] ALBEE: AN ELECTRO Ol'ERATIVE BONE CLAMP. 915 lying soft jjarts.
