Abstract:
Objective To investigate the correlation between fatty infiltration(FI),relative cross-sectional area(rCSA)of the multifidus(MF),erector spinae(ES)and postoperative new symptomatic vertebral compression fractures(NSVCF)for osteoporotic lumbar vertebral compression fractures(OLVCF).Methods The clinical and imaging data of 157 patients with OLVCF treated by surgery were collected.They were divided into postoperative re-fracture group(24 cases)and postoperative non-fracture group(133 cases)according to the presence or absence of NSVCF during the follow-up period.The FI,rCSA of lumbar paravertebral muscles(MF and ES)in the two groups were measured and calculated using Image J software.Univariate difference analysis was performed to compare whether there were differences in gender,age,T value of bone mineral density(BMD),body mass index(BMI),FI and rCSA between the two groups.Multivariate binary logistic regression analysis was used to determine the risk factors for NSVCF after surgery for OLVCF.Results Univariate difference analysis showed there were significant statistical differences in age(t=-2.596,P=0.010),T value of BMD(t=2.415,P=0.017)and FI(t=-5.006,P＜0.001)between the two groups.There were no significant statistical differences in gender(x2=0.528,P=0.468),BMI(t=1.354,P=0.178)and rCSA(t=-0.057,P=0.955).Multivariate binary logistic regression analysis showed there were significant statistical differences in FI(x2=15.560,P＜0.001),T value of BMD(x2-4.193,P=0.041)between the two groups.Conclusion The higher FI of lumbar paravertebral muscle and the lower T value of BMD of lumbar spine are the risk factors for postoperative NSVCF in patients with OLVCF.It is recommended that clinicians should pay attention to the functional exercise of lumbar dorsal muscles and the anti-osteoporosis therapy in the relevant patients.
