Abstract:
Purpose To investigate the correlation between lumbar trunk muscle mass at the L3 level and the severity of lumbar facet joint osteoarthritis (FJOA) in the middle-aged and elderly population. Materials and Methods The analysis involved 312 individuals aged between 44 and 82 years in Beijing Jishuitan Hospital from March to June 2016. The total area and CT values of the lumbar trunk muscles at the L3 vertebral body's lower endplate level were measured to calculate the skeletal muscle mass index via OsiriX image processing software. Furthermore,the severity of bilateral lumbar facet osteoarthritis at the L4-5 level was assessed using the Weishaupt grading criteria. CT value of trunk muscle at L3 lower endplate level,trunk muscle area at L3 lower endplate level,skeletal muscle index,body mass index,age and FJOA grade at L4-5 right and left sides were compared between genders. The correlation between the mean value of trunk muscle CT and FJOA grade at the lower endplate level of L3 was analyzed. Results In 109 male patients,the mean trunk muscle was negatively correlated with FJOA grade on the right and left sides of L4-5 (r=-0.25,P=0.002;r=-0.28,P=0.003),while age was positively correlated with FJOA grade on the right and left sides of L4-5 (r=0.23,P=0.034;r=0.21,P=0.033). In 203 female patients,there was a negative correlation between trunk muscle mean and both right and left FJOA grade at L4-5 (r=-0.29,P<0.001;r=-0.33,P<0.001),there was a positive correlation between age and both right and left FJOA grade at L4-5 (r=0.27,P<0.001;r=0.34,P<0.001),and there was a positive correlation between body mass index and both right and left FJOA grade at L4-5 (r=0.20,P=0.018;r=0.23,P=0.004). Partial correlation analysis,controlling for age,showed that the severity of bilateral FJOA at L4-5 was somewhat negatively correlated with the mean value of the L3 trunk muscle in the male and female groups (r=-0.239,-0.249,-0.177,-0.169,all P<0.05). Conclusion Trunk muscle mass at the L3 level is negatively correlated with the severity of FJOA,and FJOA is one of the independent factors of chronic low back pain,strengthening nutritional intake and physical exercise is beneficial to prevent the occurrence and development of sarcopenia,thereby reducing the occurrence and aggravation of FJOA and reducing the burden on patients with chronic low back pain.
