The cyclic program should allow the physically active person to remove the source of the stress to the bone, maintain fitness, promote a safe return to activity, and permit the bone to heal properly.ĭifferent study designs, populations, and classification schemes make it difficult to definitively report the incidence of stress fractures in varying populations. Once a stress fracture is suspected, a cyclic management program that incorporates the physiology of bone remodeling should be initiated. Stress fractures occur as the result of increased remodeling and a subsequent weakening of the outer surface ofthe bone. Effective management includes a cyclic process of activity and rest that is based on the remodeling process of bone.Ĭonclusions/Recommendations: Bone continuously remodels itself to withstand the stresses involved with physical activity. When a stress fracture is suspected, appropriate management of the injury should begin immediately. Increased stress leads to an acceleration of this remodeling process, a subsequent weakening of bone, and a higher susceptibility to stress fracture. Objective: To describe the anatomy of bone and the physiology of bone remodeling as a basis for the proper management of stress fractures in physically active people.ĭata Sources: We searched PubMed for the years 1965 through 2000 using the key words stress fracture, bone remodeling, epidemiology, and rehabilitation.ĭata Synthesis: Bone undergoes a normal remodeling process in physically active persons.
