Opportunistic CT Screening for Osteoporosis in Patients With Pelvic and Acetabular Trauma: Technique and Potential Clinical Impact.

To present a technique for the use of computed tomography (CT) scans in opportunistic screening for osteoporosis in patients with pelvic and acetabular fractures and to quantify the potential clinical impact in a geriatric trauma population. Retrospective cohort study. Level 1 trauma center. A total of 335 patients older than 60 years of age who presented to a Level 1 trauma center with a diagnosis of pelvic or acetabular fracture and were evaluated with a CT scan between the years 2010 and 2016. A subset of 255 patients were evaluated with a dual-energy x-ray absorptiometry scan within 6 months of the CT scan. Measurement of Hounsfield units (HU) was performed at the midpoint of the femoral neck using a standardized, ovoid section, followed by Livewire measurement. Application of this technique retrospectively to a population of geriatric patients with pelvic or acetabular fractures. (1) HUs were measured in a cross section at the midpoint of the femoral neck and, discriminant function analysis was used to establish thresholds for normal bone mineral density, osteopenia, and osteoporosis. (2) Change in the number of diagnoses of osteoporosis after application of the protocol the geriatric trauma cohort. Patients with osteopenia were identified correctly 67.5% of the time (14.3% were incorrectly grouped as normal, and 18.3% were grouped as having osteopenia). Patients with osteoporosis were identified correctly 88.9% of the time (the remaining 11.1% were assigned to osteopenic). The results of discriminant function analysis were used to establish CT thresholds for osteopenia (345 HUs) and osteoporosis (262 HUs). CT imaging obtained for pelvic and acetabular fractures can identify patients with osteoporosis without additional radiation exposure or cost. The fitted ovoid region of interest is a standard feature in most CT scan platforms and is quite simple to perform. Diagnostic Level II.

Change of Bone Mineral Density Measurement among Patients with Osteoporotic Fractures in Korean Population Using National Claim Database.

BackgroundPrior osteoporotic fractures are strongly associated with subsequent fractures. To prevent this, the diagnosis of osteoporosis following an osteoporotic fracture is important. The measurement of bone mineral density (BMD) is the first step in the diagnosis and management of osteoporosis. Therefore, this study aimed 1) to evaluate the rate of BMD measurement after osteoporotic fracture in the Korean population, and 2) to determine whether the rate of BMD measurement after osteoporotic fracture changed between 2005 and 2010.MethodsUsing the database of the Health Insurance Review Assessment Service (HIRA), we identified patients with osteoporotic fractures (hip, spine, humerus, and wrist fractures) in 2005 and 2010. BMD examinations were evaluated by using procedure codes and medicines, exclusively approved for osteoporosis treatment.ResultsDuring the study period, about half of all patients with osteoporotic fractures had BMD measurement. Between 2005 and 2010, the rate of BMD measurement significantly increased from 42.0% (65,556/156,190) to 53.9% (103,785/192,556) (P<0.001).ConclusionsOur results showed that about half of all patients with osteoporotic fractures had BMD measurement, and that screening for osteoporosis in patients with osteoporotic fractures increased between 2005 and 2010.

Optimizing Screening for Osteoporosis in Patients With Fragility Hip Fracture

Osteoporosis, the underlying cause of most hip fractures, is underdiagnosed and undertreated. The 2008 Joint Commission report Improving and Measuring Osteoporosis Management showed only an average of 20% of patients with low-impact fracture are ever tested or treated for osteoporosis. We developed an integrated model utilizing hospitalists and orthopaedic surgeons to improve care of osteoporosis in patients with hip fracture. Does our integrated model combining hospitalists and orthopaedic surgeons improve the frequency of evaluation for osteoporosis, screening for secondary causes, and patients' education on osteoporosis? Our Hospitalist-Orthopaedic Surgeon Integrated Model of Care was implemented in September 2009. We compared the rate of evaluation and treatment of osteoporosis in 140 patients admitted with fragility hip fracture at our institution before (70 patients) and after (70 patients) implementation of the care plan. Evaluation of patients for osteoporosis was higher in the postimplementation group compared to the preimplementation group (89% versus 24%). Screening of patients for secondary causes of osteoporosis was also improved in the postimplementation group (89% versus 0%), as was the proportion of patients who received education for osteoporosis management (89% versus 0%). Our model of integrated care by hospitalists and orthopaedic surgeons resulted in improvement in the evaluation for osteoporosis, screening for secondary causes of osteoporosis, and education on osteoporosis management in patients with hip fracture at our institution. This may have important implications for treatment of these patients. Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Secondary screening for osteoporosis in patients admitted with minimal‐trauma fracture to a major teaching hospital

The aim of the present study was to determine: (i) the prevalence of the investigation and treatment of osteoporosis in patients admitted to hospital with a minimal-trauma fracture, (ii) the prevalence of osteoporosis using bone mineral density assessment by dual X-ray absorptiometry (DEXA) in such patients and (iii) a clinical pathway for the management of osteoporosis in such patients. A cross-sectional study was undertaken involving all patients admitted with a fracture to Westmead Hospital, Sydney, Australia, between January 1999 and June 2000 (n = 327). Of these, 264 were excluded because of: (i) the fracture following significant trauma (n = 83), (ii) unavailability of medical records for review (n = 38), (iii) nursing home status (n = 37), (iv) previous malignancy (n = 18), (v) deceased (n = 11), (vi) recent osteoporosis screening and/or treatment (n = 18), (vii) refusal to participate (n = 37), (viii) uncontactable (n = 16) and (ix) inadequate English (n = 6). The remaining 63 patients underwent DEXA assessment and the following laboratory investigations: (i) liver function tests, (ii) urea, (iii) electrolytes, (iv) calcium, (v) phosphate, (vi) full blood count, (v) 25-hydroxyvitamin D level and (vi) thyroid-function tests. In men, levels of serum free testosterone, luteinizing hormone, follicle-stimulating hormone and prolactin were also obtained. Of the 63 study participants, 87% of the 47 women were either osteoporotic (T <-2.5) or osteopenic (-2.5 <T <-1) at a mean of 12.7 +/- 5.4 months post-fracture. Of the 16 men screened, 75% had a T-score < or =-1. Forty-four per cent of the study sample had a low 25-hydroxyvitamin D level, 6% were biochemically hyperthyroid and 40% of the men had a low serum free testosterone. Only 16% had an effective anti-osteoporotic medication added following the fracture. Secondary screening and treatment of osteoporosis in patients following minimal-trauma fracture are low. The implementation of a clinical pathway for osteoporosis management in these patients may be useful.

The relation of hand skin-fold thickness to bone mineral density in patients with Crohn's disease.

In healthy postmenopausal women, the association of skin-fold thickness (SFT) with bone mineral density (BMD) is well described, and a low SFT is a useful predictor of osteoporosis. In this study the association between hand SFT and BMD in patients with Crohn's disease was assessed; and the potential for hand SFT as a screening test for osteoporosis evaluated. In a cross-sectional study, BMD was measured at the hip and lumbar spine by dual energy x-ray absorptiometry (DEXA). SFT was measured on the dorsum of the right hand using Holtain Tanner Whitehouse calipers. One hundred and seventeen patients (48 male) with Crohn's disease and 50 (25 male) controls were studied. There was a significant correlation between hand SFT and BMD (expressed as t scores) at all four measured sites (lumbar spine r = 0.41, P < 0.0001, 95% CI 0.25-0.55, Ward's triangle r = 0.38, P < 0.0001, 95% CI 0.21-0.53, trochanter r = 0.33, P < 0.0001, 95% CI 0.16-0.48, femoral neck r = 0.38, P < 0.0001, 95% CI 0.21-0.53). On stepwise regression analysis, the association remained significant after correcting for age, weight, menstrual status and current steroid use (P < 0.05). Hand SFT was significantly lower in patients with Crohn's disease than controls (difference in means 0.51 mm, 95% CI 0.3-0.72, P < 0.0001). Mean hand SFT was significantly lower in patients with osteoporosis compared to patients with normal BMD (difference in means 0.74 mm, 95% CI 0.33-1.15, P < 0.001), as was that of osteopenic patients compared to patients with normal BMD (difference in means 0.28 mm, 95% CI 0.01-0.55, P < 0.05). In the diagnosis of osteoporosis, the sensitivity of hand SFT ranged from 29% to 93%, with specificities of 54% to 95%. Hand SFT is independently associated with BMD in Crohn's disease and is lower than in age-matched healthy subjects. Hand SFT in combination with other easily measurable confounding variables might be useful in screening for osteoporosis in patients with Crohn's disease.
