Prior to training, each recruit underwent an evaluation includ ing the following: orthopaedic examination, foot and tibial radiographs, measurements of tibial bone width, bone mineral content, bone density, aerobic physical fitness and leg power, assessments of somatotype and smoking habits, and evaluation of sociological and psy chological factors. Using a multivariate analysis, two risk factors were identified: recruits with stress frac tures had significantly narrower tibiae (P &lt; 0.001), and a higher degree of external rotation of the hip (P = 0.016). These two variables were independent and cumulative. Stress fracture morbidity was 17%, 29%, and 45% when neither, one, or both risk factors were present, respectively (P &lt; 0.001). Identification of these risk factors might explain the susceptibility of some people to stress fractures.<\/jats:p>","DOI":"10.1177\/036354659101900617","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"647-652","source":"Crossref","is-referenced-by-count":176,"title":["Stress fractures"],"prefix":"10.1177","volume":"19","author":[{"given":"Michael","family":"Giladi","sequence":"first","affiliation":[{"name":"Tel Aviv Medical Center, Ichilov Hospital, Tel Aviv"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Milgrom","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hadassah Hospital, Jerusalem"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ariel","family":"Simkin","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Hadassah Hospital, Jerusalem"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yehuda","family":"Danon","sequence":"additional","affiliation":[{"name":"Israel Defence Forces Medical Corps, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1991,11,1]]},"reference":[{"key":"atypb1","unstructured":"American Academy of Orthopaedic Surgeons: Joint motions: Methods of measuring and recording.
