Effects of thoracolumbar osteoporotic vertebral compression fracture on spinal balance and lumbar back function in the elderly patients
Objective To analyze the effects of conservative treatment of osteoporotic vertebral compression fracture(OVCF)on spinal balance and lumbar back function in elderly patients.Methods The imaging data of 147 patients with thoracolumbar vertebral OVCF underwent conservative treatment were retrospective analyzed in OVCF group.The patients were divided into three groups of A(with T6-T10 fractures,38 cases),B(with T11-L2 fractures,59 cases)and C(with L3-L5 fractures,50 cases).Forty-four patients with non fractured degenerative spinal diseases were taken as the control group.The bone density values of 191 patients were collected.The sagittal and coronal parameters on a full length spine X-ray were measured,which included thoracic kyphosis(TK),thoracolumbar kyphosis(TLK),lumbar lordosis(LL),pelvic incidence angle(PI),pelvic tilt angle(PT),sacral slope angle(SS),the distance between the C7 plumb line and the midline of the sacrum(C-Align).The VAS painscore and Oswestry disability index(ODI)score were recorded by questionnaire survey and telephone follow-up.Results There were statistically significant differences in TK,TLK,LL,C-Align,VAS pain score and ODI scores between the OVCF group and the control group(P<0.05),but there were no significant differences in PI,PT,and SS between the two group(P>0.05).There were statistically significant differences in TK,TLK,C-Align,VAS pain score and ODI score among the three groups of A,B and C(P<0.05),while there were no statistically significant differences in LL,PI,PT and SS among the three groups in OVCF group(P>0.05).Conclusion Thoracolumbar OVCF can lead to spinal imbalance in elderly patients,which thereby exacerbating the lumbar back pain and reducing lumbar back function.
