Bone stress injuries (BSI) are common among distance runners and research investigations examining risk factors for BSI among men are limited. Therefore, investigations are needed to determine if men with a history of BSI have skeletal properties that may heighten BSI incidence. OBJECTIVES: To analyze differences in bone density, bone geometry, and estimates of bone strength in male runners with and without a BSI history. DESIGN: Cross-sectional. METHODS: We recruited 36 male distance runners ages 18-41 for this study. We used peripheral quantitative computed tomography (pQCT) to assess volumetric bone mineral density (vBMD, mg\/mm(3)), bone geometry (total and cortical bone area, mm(2)), tibia robustness (total area\/tibia length, mm) and estimates of bone strength (section modulus and polar strength-strain index, mm(3)) at 5 tibial sites. RESULTS: After adjusting for age, the BSI group had more slender tibias (9%), lower stress strain indices (-16%), lower section moduli (-17%) and smaller total cross-sectional (-11%) and cortical areas (-12%) at the 66% site of the tibia compared with controls (P<0.05 for all). Similar differences were found at all other measurement sites. After adjusting for body size, differences in bone outcomes remained significant at the 66% site. CONCLUSIONS: These results indicate that men with a history of BSI have lower estimated bending strength compared to controls because of narrower tibias. However, differences are largely attenuated in the distal (1\/2) of the tibia after adjusting for body size. Thus, smaller tibia size, particularly at the mid-diaphysis, may be an important indicator for BSI incidence.<\/p>\n","protected":false},"excerpt":{"rendered":"
