results vvere satisfactory. Ninety per cent of the patients had resumed
their previous work within 6 months of the operation. The average time
in hospital was 19.6 days. The average time from the beginning of symp-
toms until work had been resumed was in this series 4.3 months.
The late results of this survey are that 61% of the patients are symp-
tom free and 23% have mild symptoms. All of those are working full-time,
while 7 are doing lighter work than before surgery. Five patients or 16%
were improved by the primary operation, however only for a certain time.
Three of those had subsequently a recurrence of symptoms and have not
been able to resume their work. The other two were reoperated on be-
cause of a recurrence of sciatic and low-back pain. Both of those improved
after the second operation in spite of negative operative findings and are
now working full-time.
In the discussion these results are compared to the results of other
authors. The indications for early surgical treatment of herniated lumbar
discs are also briefly discussed.
