Results of surgical treatment of adults with idiopathic scoliosis
PD Sponseller, MS Cohen, AL Nachemson, JE Hall and ME Wohl
The outcome of surgical treatment of idiopathic scoliosis in forty-five
adults was studied with special attention to pain, function, self-image,
and pulmonary function. All of the patients were more than twenty-five
years old at operation and had been followed for more than three years.
Every patient who was operated on by one of us (J. E. H.) and who met these
criteria was evaluated. The magnitude of the curves averaged 66 degrees.
Standardized gradations of pain and function showed improvement over-all,
but significant impairment remained. There was a reduction in the levels of
peak and constant pain, but no change in the frequency of peak pain after
operation. The number of patients who were pain-free after surgery was not
increased. Functional impairment due to the scoliosis was lessened, and the
ability to perform the common activities of daily living was improved, but
no important changes in occupation or recreational activity were recorded.
Correlations of pain or function, or both, and the changes in either, were
found with only two parameters: age at follow-up and physical occupation.
Pulmonary function, as measured, did not change. Eighteen (40 per cent) of
the patients had a minor complication and ten (20 per cent), a major
complication; there was one death, due to pulmonary embolism, of a patient
who was excluded from the series. In view of the high rate of
complications, the limited gains to be derived from spinal fusion should be
assessed and clearly explained to patients before the procedure is
undertaken.
