The Application Of Msct About Adult Lumbar Scoliosis

Part1Correlative study of Adult lumbar scoliosis and osteoporosisObjective: To investigate the correlation between adult lumbar scoliosisand osteoporosis.Methods: From Jan.2011to Dec.2011,100patients diagnosed withadult lumbar scoliosis were included in the case group. There were32malesand68females with an average age of64.5years(ranging from36to87years),control group had100cases without scoliosis. There were42malesand58females with an average age of62.8years(ranging from36to82years). All the patients underwent lumbar-CT examinations to confirm thediagnosis. Through the computer workstation post-processing function, thevolume of vertebral body, vertebral CT value and vertebral bone trabecularbone volume percentage (BV/TV) of two groups of patients were measured,and the differences between the two groups were compared. withreconstruction of trabecular bone3D-image, the shape of trabecular bone andthe number change between the two groups were compared.Results: By comparing the vertebral CT value and BV/TV value,significant difference was found among the lumbar scoliosis group and controlgroup (P<0.05), but the volume of vertebral body had no significant differencebetween the lumbar scoliosis group and control group (P>0.05). Thetrabecular bone structure of the two groups in3D-VR image was displayed,the continuity and amount of trabecular bone decreased in lumbar scoliosisgroup. According to the comparison of BV/TV value at different ages, theBV/TV value had a negative correlation with age.Conclusion: Osteoporosis is a risk factor for adult lumbar scoliosis,Thecontinuity and amount of trabecular bone decreased with the increasing of age. Part2Clinical characteristics of intervertebral disc and lumbarzygapophysis in adult lumbar scoliosisObjective: To investigate the correlation between lumbar intervertebraldisc and adult lumbar scoliosis, and the clinical significance of vertebral smalljoints in adult lumbar scoliosis.Method: From Jan.2011to Dec.2011,100patients diagnosed with adultlumbar scoliosis were included in the case group. There were32males and68females with an average age of64.5years (ranging from36to87years), all thepatients underwent lumbar-CT examination to confirm the diagnosis. Theintervertebral disc asymmetric index was investigated. The correlationbetween intervertebral disc asymmetric index and degrees of lumber scoliosiswere evaluated. The changes of articular surface and joint space, thecontrapuntal relationship of zygapophyseal joint, the degeneration of disc,calcification of ligament flavor and narrowing of lateral recess were observedand measured.Results: The average intervertebral height was44.62±0.77mm in theconcave side and48.86±0.85mm in the convex side, which showedsignificant difference between the two sides(P<0.05). The disc asymmetricindex was0.86±0.16,which showed positive correlation between discasymmetric index and degree of scoliosis (P<0.05). The changes ofzygapophyseal joint were found to be varied such as subchondral facetsproliferation and sclerosis in90cases, changes of auricular cavity in85cases,the degenerative changes within lumbar also including little joint's hemidislocation or abnormal alignment in53cases,and degeneration of disc,calcification of ligament flavor and narrowing of lateral recess in79cases.Conclusion：The degree of scoliosis is positively related to the discasymmetric index. Disc degeneration and vertebral small joint degenerationare important causes of adult lumbar scoliosis.
