1. Internal fixation reduced the hospital mortality to 12.6 per cent., as compared to 34 per cent. after treatment. in traction.
2. Severe senile mental deterioration occurred in 2.1 per cent. of the cases following internal fixation, as compared with an incidence of 11 per cent. in the group treated by traction.
3. The survival rate at the end of four years among the patients operated upon was 17 per cent. higher than in the group upon which operation had not been performed.
4. All complications were reduced sharply in those patients submitted to internal fixation.
5. Although union of the fracture took place in all survivors, the functional result in those treated by internal fixation was vastly improved.
