Lower extremity overuse bone injury risk factors in collegiate athletes: a pilot study.

摘要: Background and purpose There is limited evidence regarding risk factors for lower extremity overuse bone injury (LEOBI) in collegiate athletes. The purposes of the study were to: 1) determine incidence LEOBI selected sports its impact on athletic participation ADL, 2) assess relationships between factors, 3) establish viability using calcaneal densitometry as a screening tool to identify LEOBI. Study design Prospective analytical cohort design. Methods Collegiate athletes (swimming/diving, women's soccer, field hockey, cross-country/track) at one university invited participate. Consenting completed an initial questionnaire including demographic information, history, menstrual function. Measurements included height/weight, hip abductor strength, foot posture index, mineral density. Athletes monitored potential nine months algorithm was used if physician referral required. primary outcome interest occurrence physician-diagnosed If diagnosed by physician, athlete follow-up visit repeat density scan. All scan end year final questionnaire. Athlete demographics summarized descriptive statistics differences continuous analyzed t-tests ANOVA. Finally, categorical variables chi-square relative risk. Results 84 (64 female, 20 male) consented Over period, eight (one male, seven females) with (LEOBI group), five stress fractures three medial tibial syndrome. other 76 who did not have diagnosis placed non-LEOBI group. Five cross-country/track athletes; no swimming/diving had injury. Sport (cross-country/track) significant value 2.26 (95% CI = 1.18-4.32) association sex, body mass type, difference or measures groups (p>.05) when analyzing all When ground-based only (n=44), right (p .05) left =.07) calcaneus. developing based below mean participants 2.1 (95%CI 1.09-3.35) 1.53 CI=.80- 3.06) right. Conclusion this population approximately 10%. Risk sport decreased This supports use measurement suggests need further investigation into additional factors. Level 2.
