Reflex sympathetic dystrophy after operative procedures on the lumbar spine

Between July 1987 and April 1991, reflex sympathetic dystrophy developed in
eleven patients after a posterior operation on the lumbar spine. The
average age of the patients was forty-four years (range, twenty-eight to
sixty years). The preoperative diagnosis had been lumbar spondylolisthesis
or lumbar instability, associated with degenerative disc disease or with
osteoarthrosis of a facet joint. Ten patients had posterior stabilization
with bilateral arthrodesis and interpedicular fixation, with use of plates
or screws; the remaining patient had a posterior hemilaminotomy of the
fourth and fifth lumbar vertebrae, partial discectomy, and foraminal
decompression of the fifth lumbar-nerve root. After the operation, all
patients had burning pain, vasomotor dysfunction, and dystrophic changes in
the lower limb and foot; in four patients, the symptoms were bilateral. The
symptoms began four days to twenty weeks after the operation. The patients
were followed for nine months to four years. Treatment was most successful
in four of six patients who had had at least one nerve-block of the
sympathetic lumbar trunk in addition to physiotherapy.
