INTRODUCTION: The aim of this study was to evaluate the mechanical status of the spine in patients with spastic diplegia 17-26 years after selective dorsal rhizotomy (SDR). METHODS: We compared original radiographic reports from our earlier short-term follow-up study with current X-rays. In addition, we obtained magnetic resonance images (MRI) of the spine and additional information regarding back pain and clinical assessments. RESULTS: Thirty patients (17 males and 13 females; median age 26.8 years) participated in the current study, with median follow-up times of 4.0 and 21.4 years. Comparison of the X-ray results showed respectively: scoliosis 0% and 57%; kyphosis 0% and 7%; lordosis 21% and 40%; spondylolysis 18% and 37%; and spondylolisthesis grade I occurred in one patient. The only statistically significant difference was found for scoliosis (p < 0.01). The majority had Cobb angles <30 degrees with only two patients with curves of 35 degrees. MRI scans showed spinal stenosis in 27%, black discs in 10%, and disc protrusion in 3%. Daily back pain was reported in 17%, while 23% reported "moderate disability" as a result of back and leg pain. No patient to date has required any surgical intervention on the spine. CONCLUSIONS: Except for spondylolisthesis, spinal deformities did appear to progress with time. However, this increase was not marked, and the development of relatively mild scoliosis was the only statistically significant increase. This group of patients requires continued follow-up. Further studies are required to ascertain the natural history of spinal deformity in adults with spastic diplegia who have not had SDR.
