Lumbar Osteoarthritis in Patients with Osteoporosis Evaluated with the Lane and Wilke Scale and its Effect on Dexa Scores.

OBJECTIVE

This study aimed to compare bone mineral density (BMD) values in patients with lumbar osteoarthritis (OA) with and without osteoporosis (OP). This study evaluated the effect of lumbar osteoarthritis in patients with osteoporosis on Dexa scores using the Lane and Wilke scale.

METHODS

A total of 51 individuals with OA, 20 with OP, and 31 without OP were included in the study. Lumbar osteoarthritis was assessed and recorded using the Lane and Wilke scale. BMD was measured by dual-energy X-ray absorptiometry (DEXA) at the waist and hip (femoral neck, lumbar vertebrae). Frax assessed the risk of osteoporosis and fracture risk.

RESULTS

The mean age of patients with OP was 68.1±8.2 years, and the mean age of patients without OP was 68.6±9.4 years. There was a significant decrease between the lumbar vertebrae and femoral neck BMD values of the two groups in favor of the osteoporosis group. The t-scores of the OP group were significantly lower (p = 0.045). All variables showed a statistically significant difference between the group with OP and those without OP (p<0.05). The median values of L1-L2, L2-L3, L3-L4, and total L1-L4 were higher in absolute value in the group with OP. In frax hip and frax primary osteoporosis, the median values were higher in the group with OP than in the group without OP (p = 0.023/p = 0.020). All L1-L2, L2-L3, and L3-L4 dexa parameters with and without OP were not significantly different between the groups according to the Lane and Wilke classification (p > 0.05).

CONCLUSION

There was no statistically significant difference between DEXA parameters in osteoporosis and non-osteoporosis patients with low back osteoarthritis (according to the Lane and Wilke classification).
