“…In the population of postmenopausal women investigated in this study, a significant correlation was found between each DXA site and the QUS parameters. Consistent with other studies among older women, the correlations between the QUS T score and DXA T score at the hip and femoral neck were better than those for the lumbar spine T scores …”

“…Consistent with other studies among older women, the correlations between the QUS T score and DXA T score at the hip and femoral neck were better than those for the lumbar spine T scores. 17,19 The ability of calcaneal QUS to identify women with a DXA T score of -2.5 or lower at the right hip (AUC, 0.887) excelled in comparison to a T score of -2.5 or lower at the lumbar spine (AUC, 0.704) or left femoral neck (AUC, 0.824). Additionally, noteworthy was the very strong AUC of 0.956 for measurements of the right calcaneus and right hip in patients between 50 and 65 years, which would indicate an especially high potential use of this device for the prescreening of hip fractures in women of this age group.…”

Objectives Calcaneal quantitative ultrasound (QUS) is a readily accessible and radiation‐free alternative to dual‐energy x‐ray absorptiometry (DXA) for assessing bone mineral density (BMD). Results obtained from QUS measurement cannot directly be compared to DXA, since these techniques capture different bone‐specific parameters. To identify individuals who are likely to have osteoporosis by DXA, device‐specific thresholds have to be defined for QUS. This cross‐sectional study evaluated the accuracy of QUS to identify postmenopausal women with osteoporosis, defined as a T score of –2.5 SDs or lower by DXA, and to calculate device‐specific cutoff values for the QUS device investigated. Methods We assessed BMD at the lumbar spine, bilateral femoral neck, and total hip sites with DXA and QUS parameters of the right and left calcanei in a cohort of 245 postmenopausal treatment‐naïve women between 40 and 82 years. Correlation coefficients for BMD and QUS parameters were calculated. Receiver operating characteristic curves were generated, and areas under the curves (AUCs) were evaluated. Cutoff values for QUS were defined. Results Calcaneal QUS had the ability to identify postmenopausal women with a T score of –2.5 or lower at the right hip (AUC, 0.887) and left femoral neck (AUC, 0.824). Cutoff values for the QUS T scores at the right (–1.455) and left (–1.480) calcanei were defined for screening purposes. Conclusions This study provides insights into the comparative performance of QUS with DXA. Considering the diagnostic accuracy of this modality in comparison to DXA, it can be recommended as a prescreening tool to reduce the number of DXA screenings.

“…Several studies have documented the reliability of calcaneal QUS in assessing low BMD. 14,15,16,17,18 In our study, OSTA index did not correlate with BMD (T-score) when the entire sample was analyzed. However, on subgroup analysis based upon age, OSTA index significantly correlated positively with BMD in women in the age group of 50-55 years.…”

“…These data speak to the importance of continued efforts in patient education and the need for more proactive referrals to specialists in nutrition and obesity management. Much like the emerging role of the orthopaedic surgeon in the early management of osteoporosis and metabolic bone disorders in postfracture care in older populations [13,[16][17][18], we believe SCFE presents a unique and perhaps the most important opportunity for the orthopaedic surgeon to be proactive in education and clinical intervention regarding obesity, which can greatly improve the prognosis for SCFE as well as the overall health of the pediatric patient. We also suggest that prophylactic pinning might be considered for morbidly obese patients.…”

Background Slipped capital femoral epiphysis (SCFE) is occurring in greater numbers, at increasingly younger ages, and more frequently bilaterally (BL-SCFE). Obesity is one risk factor for SCFE. However, it is unclear whether postoperative decreases or increases in body mass index (BMI) alter the risk of subsequent contralateral SCFE. Questions/purposes We therefore determined whether (1) BMI percentile was a risk factor for BL-SCFE; and (2) postoperative increases and/or decreases in BMI percentile influenced the risk for BL-SCFE. Methods We retrospectively reviewed the records of 502 patients surgically treated for SCFE and identified 138 (27%) with BL-SCFE and 364 (73%) with unilateral SCFE (UL-SCFE); 173 patients, 60 (35%) with BL-SCFE and 113 (65%) with UL-SCFE met our inclusion criteria. Risk factors included sex, age, slip stability, slip chronicity, slip angle, and obesity. Percentile BMI was recorded at the time of first SCFE surgery, at the time of last followup for patients undergoing UL-SCFE, and at the time of second SCFE surgery for patients undergoing BL-SCFE. Results Sex, age, slip stability, and slip angle were not associated with BL-SCFE. Postoperative obesity (odds ratio [OR], 3.5; 95% confidence interval [CI], 1.2-9.7) and acute slip chronicity (OR, 2.9; 95% CI, 1.3-6.7) had higher risks for sequential BL-SCFE. Obese patients who became nonobese postoperatively had a decreased risk of sequential BL-SCFE compared with those who remained obese (OR, 0.16; 95% CI, 1.2-116.5). Conclusions Only postoperative obesity and an acute slip were risk factors for sequential BL-SCFE. BMI reduction to lower than the 95% percentile after SCFE surgery was associated with lower risk for BL-SCFE development. The data suggest early supervised therapeutic weight management programs for patients treated for UL-SCFE are important to reduce risk of subsequent SCFE.
