Abstract:
OBJECTIVES: The purpose of this study was to determine the association between the bone mineral density (BMD) and severity of spinal osteoarthritis (spondylosis) in osteoporotic spinal compression fracture. METHODS: Fifty six patients were evaluated 66 cases had an osteoporotic thoracolumbar compression fracture between January 2008 and June 2010. The average patient age was 76.2 years (M/F : 8/48). Age and body mass index (BMI, kg/m2) were measured, and the BMD was performed using peripheral quantitative computed tomography (pQCT). Simple thoracolumbar (T-L) spine lateral radiography was evaluated for three criteria: presence of osteophytes, disc space narrowing and vertebral body sclerosis. The findings were graded 0 to 3 and analyzed statistically for a correlation with the BMD and fractured vertebrae. RESULTS: Acute compression fractures comprised of 15 cases and the most common site of acute fractures with old fractures was lumbar spine (L1; 30 cases, 45.4%). The average of BMI was 23.32 and BMD (T-score) was -4.47. Pearson's rho showed a positive association between the weight, height and the BMD (P < 0.01). In terms of the BMD versus spondylosis, there was a positive association with high score in the high order cortical bone. Compression fractures occurrence rate in the absent and present of spondylosis was 74.3% and 22.4%, and 69% occur in the spinal segmental with no bony spur with chi-square test (P < 0.01). CONCLUSION: In the present of spondylosis was high score of cortical BMD and low rate of compression fracture. Spondylosis could be one of a factor of the occurrence in acute and adjacent compression fracture after old fractures.
