ABSTRACT
Patients found to have isolated osteoporosis at the 1/3 radius (1/3RO) represent a therapeutic dilemma. It is unknown whether 1/3RO is associated with an increased risk of fragility fractures, and is therefore unclear whether these patients should be treated similarly to those with osteoporosis at central sites. This retrospective study investigated the clinical significance of 1/3RO by comparing medical history, fracture prevalence, areal BMD, and Trabecular Bone Score in postmenopausal women with 1/3RO (nâ¯=â¯107) to age-matched women with osteoporosis at the hip and/or spine (PMO, nâ¯=â¯214), and to controls without osteoporosis at any site (nâ¯=â¯214). We then compared the clinical and densitometric characteristics among women with 1/3RO according to fracture history. The mean age of the 535 women included in the study was 71 ± 8 yr. Women with 1/3RO had BMD in the osteopenic range at all other sites (mean spine T-scoreâ¯=â¯-1.0, total hipâ¯=â¯-1.4, femoral neckâ¯=â¯-1.7). Women with 1/3RO reported similar calcium and vitamin D intake, prevalence of primary hyperparathyroidism, chronic kidney disease, and other comorbidities compared to the other groups. The prevalence of an osteoporotic fracture of the spine, hip, wrist, or humerus tended to be higher among women with PMO compared to 1/3RO or controls (PMO 31%, 1/3RO 21%, Controls 23%, pâ¯=â¯0.07). Among women with 1/3RO, fracture prevalence was related to older age. No other clinical characteristic distinguished women with and without fracture. Neither BMD at other sites nor TBS differed according to fracture history. Among postmenopausal women with 1/3RO, those who are older are at an increased risk of fracture, even when T-scores at other sites are well above the osteoporosis threshold. Additional research is needed to confirm our results, and to assess whether treatment should be considered to reduce fracture risk in older women with 1/3RO.
