The Imaging Features of Lumbar Degenerative De Novo Scoliosis
2014
Objective To investigate the imaging findings and clinical manifestations of lumbar degenerative de novo scoliosis( LDDS). Methods 887 patients( 453 females and 434 males) with LDDS were reviewed. Females and males were divided into 5 groups according to age( 40≤age 50,50≤age 60,60≤age 70,70≤age 80,80≤age 90). The imaging findings in different genders and ages,such as the proportion,curve direction,Cobb angle,apex vertebra position and possible degenerative changes of LDDS were analyzed. The difference of Cobb angle between genders and ages were analyzed using R software package. Results LDDS was mainly suffered by people aging more than 50 years old. LDDS showed mostly left curve direction and many apex vertebra positions locate in L2 /3intervertebral space. Cobb angle ranges from 13°to 46°combined with degenerative changes in centrum,intervertebral disc,and zygapophysial joints. There was significant difference of cobb angle distribution between genders( t = 98. 853,P 0. 01). Cobb angle was higher in females than in males. In addition,cobb angle increased with age increased( t = 21. 214,P 0. 05). Conclusion The imaging findings of LDDS with different genders and ages has great value in clinical assessment,diagnosis and differential diagnosis,which have guidance of clinical treatment.
