Performing bone densitometry without consideration to side of greater weakness may lead to underestimation of BMD and under treatment of femoral neck fractures in the high-fall-risk patients.

Evaluation of bone mineral density (BMD) is an essential factor for estimating fractures of the femoral neck, as per the analysis published in the Journal, PM & R. The subjects with the long-term residual lower extremity (LE) weakness after polio exhibited reduced BMD, linked with the weakness of muscles.

This retrospective study assessed whether the BMD of femoral neck varied from side to side among people with asymmetrical LE muscle infirmity along with the persons who were at risk for under diagnosis of low BMD, as the low BMD or osteoporosis diagnosis significantly associated with the unilateral evaluation of the femoral neck. The patients selected for the analysis were of >18 years old with full appropriate information. The side of LE weakness (strength score), BDt T scores, and BMD divisions based on standard T-score limits were taken as the major study outcomes. 

A total of 43 individuals found to have at least one bilateral LE strength and femoral neck T scores. Fourteen subjects exhibited BDt on their stronger LE and 14 (32.5%) on their stronger LE. Further, the T scores noticed to be higher in stronger LE than the weaker LE. Analysis of osteoporosis or low bone density or was more common based on T scores have chosen on a weaker LE than a stronger LE.
Therefore, in the little sample, using strong-limb T scores ended in fewer people described as having osteoporosis or low bone density than when weak-limb T scores were used. Depreciating BMD loss may involve inadequate treatment and enhanced risk of mortality, morbidity, and costs linked with osteoporosis of femoral neck in this high-fall-risk class. This implies a significant association of BMD and femoral neck fractures.
