Abstract:Objective To evaluate the radiological features and clinical findings in osteoporotic patients with degenerative lumbar scoliosis (DLS).Methods From November 2017 to December 2021,27 DLS patients combined with osteoporosis (OP) were enrolled as OP group.The OP group had 5 male and 22 femaile patients and had an average age of (68.1±7.4) years (51~79 years).At the same time,another 27 DLS patients without osteoporosis were recruited as the nonosteoporosis (NOP) group.The NOP group had 8 males and 19 females and had an average age of (66.3±6.9) years (53~76 years).Bone mineral density (T-score) and clinical symptoms were recorded.The radiographic parameters were measured in standing full spine X-ray film and further compared between two groups.The correlation between the T-score and radiographic parameters was analyzed in the OP group.Results The median T-score in the OP group (-3.0±0.6) was significantly lower than that in the NOP group (-0.6±1.4).The percentage of back pain,motor deficit and sensory deficit were comparable between two groups (P>0.05).There were 13 left lumbar curves and 14 right lumbar curves in the OP group.There were 11 left lumbar curves and 16 right lumbar curves in the NOP group.No significant differences were observed in terms of radiographic parameters including lumbar and thoracic cobb angle,apical vertebral translation,apical vertebral rotation,thoracic kyphosis,lumbar lordosis,coronal and sagittal trunk shift (P>0.05).A significant correlation was found between Tscore and thoracic kyphosis in OP group (r=-0.568,P=0.022).Conclusion The coronal and sagittal profile are comparable between DLS patients with and without osteoporosis.The severity of osteoporosis is obviously correlated with thoracic kyphosis in osteoporotic patients.
