RESUMO
OBJECTIVES: The objective of this study was to examine and identify risk factors associated with the development of sacral stress fractures in order to improve diagnosis in clinical practice. METHODS: Electronic search strategies in PubMed, CINAHL, Scopus, and SPORTDiscus were combined with a hand search to identify articles for inclusion. Studies were considered if they described patient cases in which imaging confirmed diagnosis of a sacral stress fracture, and the diagnosis included whether the fracture was a sacral insufficiency or sacral fatigue stress fracture. RESULTS: In those that developed sacral insufficiency fractures, the risk factors that were most prevalent included osteoporosis, pelvic radiation therapy, rheumatoid arthritis, long-term corticosteroid therapy, and postmenopausal, each with a prevalence of 100%. Risk factors with 100% prevalence in those diagnosed with sacral fatigue fractures included recent increase in training intensity and deficient diet. DISCUSSION: A pattern of signs and symptoms are consistent among subjects with sacral stress fractures. Patients being unsuccessfully treated for low-back and buttock pain who fit the risk factor profiles for sacral stress fractures should be referred to a physician for further diagnostic workup.
