ABSTRACT Identification of atypical femoral fractures (AFFs) can be challenging. To assist in the radiological assessment, an American Society for Bone and Mineral Research (ASBMR) Task Force developed a case definition for AFFs in 2010, revising it in 2013. How the revised definition performs in a community setting compared with the 2010 definition is unknown. We applied the 2013 criteria to 372 femoral fractures that occurred between January 1, 1996, and June 30, 2009, employing two independent expert physician reviewers. We used radiographs that had been categorized in a previous study on the incidence of atypical fractures using 2010 ASMBR criteria (BEAK1). In this follow-up study (BEAK2), the same reviewers reviewed all previously identified femoral shaft fractures (FSFs) (n = 197) and distal femur fractures (n = 131) plus a 15% random sample of intertrochanteric fractures (n = 49). After initial review, agreement between the two reviewers ranged from 63% to 100% for specific features, and 84% of radiographs received the same overall classification. Fewer fractures met the 2013 compared with 2010 ASMBR case definition of AFFs (37 per 2013 criteria versus 74 per 2010 criteria). Forty-three radiographs (58%) categorized as AFFs according to 2010 criteria were no longer AFFs when 2013 criteria were applied, and an additional 12 non-atypical FSFs according to 2010 criteria were reclassified as AFFs according to 2013 criteria. The major cause of AFF reclassification was the change in the definition of transverse configuration. The modification of the comminution, non-traumatic, and periosteal/endosteal thickness criteria resulted in the reclassification of non-atypical FSFs to AFFs. Incidence rate of AFFs according to 2013 ASBMR criteria was lower overall during the 13 years of observation than when the 2010 ASBMR criteria were applied, although we saw a slight increase starting in 2000. As in BEAK1, we found that those with AFFs were younger, more often female, and had a higher exposure rate to bisphosphonates than those with non-atypical FSFs. As we continue to unravel the demographics of those who suffer from AFFs, our study adds information about how the change in criteria influences epidemiological work. © 2017 American Society for Bone and Mineral Research.

Background Clinical determination of bone fracture healing remains qualitative, typically determined through the combination of plain film radiographs, clinical assessment, and patient-reported pain. Importantly, standard radiographs can only detect bone formation in the fracture site after sufficient tissue mineralization has occurred, restricting utility to the later stages of bone repair. A more rigorous method for determining fracture healing progression could significantly improve patient care. Quantitative biomarkers have gained diagnostic value in many clinical indications. Multiple bone turnover biomarkers have been successfully utilized for diagnosis and clinical management of osteoporosis. However, there remains limited evidence for the correlation and diagnostic efficacy of these biomarkers when applied to fracture repair. Methods and findings Here we present data from a large cohort of participants without (n = 111) or with (n = 153) fracture with the primary outcome of interest our blood-based biomarker which detects the degradation product of the trimeric collagen X protein (CXM). Collagen X is a transient extracellular matrix protein synthesized by hypertrophic chondrocytes during the soft callus phase of endochondral fracture repair. Our data show that healthy patients with an age range of 21−85 years without fracture (enrolled 2018−2020) have low circulating levels of CXM (median = 563.4 pg/mL; interquartile range (IQR) [483.2, 771.1]) that do not vary independently with age (r = 0.04, p = 0.26) or sex (p = 0.42). Fracture data includes patients with an acute closed or low grade open (Gustilo type I or II) tibial or femoral shaft fracture from a secondary analysis of the VitaShock study (NCT02786498, n = 102: enrolled through the University of Maryland 2016−2019), complemented by a new prospectively enrolled observational study that recruited from the Oregon Health & Science University level 1 academic trauma center (n = 51: enrolled 2019−2023) that were followed until the patient was deemed clinically healed or until they failed to return for follow-up. We show that in serum CXM positively correlates to the bone biomarkers N-terminal propeptide of type I procollagen (P1NP, r = 0.50, p < 0.0001), C-terminal telopeptide of type I collagen (CTX, r = 0.40, p < 0.0001), and osteocalcin (r = 0.26, p = 0.0411); with a negative correlation to the obesity biomarker leptin (r = −0.31, p = 0.0138). Further, patients with early healing exhibited a peak in CXM at 6 weeks of 1,092 pg/mL (95% confidence interval (CI) [804.8, 1,379]), which was significantly higher than patients with normal healing of 630.8 pg/mL (95% CI [399.9, 861.8]; p = 0.016). We then show that we can reliably transfer this assay from serum collection through venipuncture to a dried blood spot (DBS) collected by finger prick (r = 0.75, Serum = 0.4217*DBS + 181.9, p < 0.0001). Using DBS, the prospective clinical observational study finally suggests that median time-to-peak CXM is at 25.5 days following the elimination of outliers (n = 6) using Robust Regression and Outlier Removal (ROUT, Q = 1%). This study did not find significant differences in CXM expression according to age, sex, or bone that are likely due to the main limitation of an observational study. Conclusion This rigorous data set supports the future prospective use of the CXM biomarker collected by finger prick in interventional fracture studies and/or in observational studies requiring quantitative assessments of long-bone healing.

Background: Osteoporosis continues to be underdiagnosed and inadequately treated in older hip-fracture patients. Our aim was to improve the rate of osteoporosis treatment with IV bisphosphonate therapy in eligible patients admitted for hip-fracture surgery. Methods: The present study was designed as a quality improvement initiative using Plan-Do-Study-Act (PDSA) cycles at an academic medical center in Portland, Oregon, over 2.5 years. A protocol was developed (1) to administer IV zoledronate on postoperative day 2 to inpatients aged ≥50 years who underwent surgery for a low-energy hip fracture and (2) to formally diagnose osteoporosis during admission. The protocol was introduced across 3 care settings in a stepped-wedge manner. Outcome measures were the percentage of inpatient zoledronate administered to eligible patients and formal documented diagnosis of osteoporosis. Balance measures included fever after administration and hospital length of stay (LOS). Measures were assessed through quarterly chart review and tracked via control charts. Results: The rate of zoledronate administration significantly increased from 34.5% (29 of 84) to 74.6% (53 of 71) following the second PDSA cycle (p < 0.001). Documented osteoporosis diagnosis also significantly improved from 51.0% (53 of 104) to 85.7% (96 of 112) following the second PDSA cycle (p < 0.001). No significant differences were shown for hospital LOS, and 1 of 82 patients had medical work-up for post-infusion acute phase reaction after administration. Conclusions: This initiative was effective at improving osteoporosis diagnosis and treatment among older hip-fracture patients at our institution. Protocol development for administrating inpatient zoledronate after hip fracture is a reliable way to predictably offer bone health care and secondary-fracture prevention to hip-fracture patients and can be adapted and implemented at other institutions. Level of Evidence: Diagnostic Level III. See Instructions for Authors for a complete description of levels of evidence.
