mentioned           arid discussed          briefly.
         First,    it is believed         by some         that       using      a (‘Oniservative         amputations       merely    (lelays   the
inevitable         amputations          at a higher           level.       In the presenit          series    there   were      only  three   late
complications.                             Ins one               patient.,                    fourteens              months                 after         complete                      healing,               gamsgremse                of the
enstire            leg       developed                        amid           a reamputatiomn                              ss’as          performed;                  ins onne pat iemst,                             one       year              after
complete                    healinng,             a small    superficial     infection    developed      which    was easily controlled;     amid
oise        patient              died            of coronary-artery          disease   three     monnths    after  complete  healing.    Ins the
follow-up                    study              of Mclcittrick        ansd his coworkers         only six of 146 patients had reamputa-
tioni       at a higher                         level.
            The second                          criticism is that                              many              of the        patiemnts             suitable                   for     tramnsmetatarsal                             amputa-
tion         riced           only              removal                 of the              innvolved                toes.          Yet,           if treatment                        is limited                to      the          innvolved

gangrene                    may           at      any           time             develop                 in the         remaining                    toes,          the          most          vulnerable                     part          of      the

             The           trenid            toward               conservatism                              is based                   on         the         marked                reductions                    in       morbidity                        and          mortality                   after

methods                   and          geriatric                care.         Seconsd,                  the          better            control                of infection                       because               of the              intelligent                   use          of rest             and

Third,              the         fear         that          reamputation                              will          be        necessary                   because                  of infection                    and          spreadimig                        gangrene                has          been
diminished,                       since            the      latter            occurs               less         frequently,                       and          is more                  readily            controlled                      when             it does             occur.

           On         the         sul)je(’t                    of          synspathectomy,                                      I likewise                      have              little         to        say.             Our          knowledge                         of      the      indications                   for
synnpatheo’tonsy                                is still                    based            erntirely                   on         clinical               impression.                        I realize                      that             this          is a very                  efficient              measure
for      the       care           of suo’in comnoiit.ions                                        Its inntermit.tennt                              claudication,                            but        I still               doubt              that           it is useful                 for      gangrenous
toes.
