Stress fracture in soldiers: a multifocal bone disorder. A comparative radiological and scintigraphic study.

Abstract

Forty-two military recruits with suspected stress fractures were evaluated by radiographs and radionuclide images. In 3 cases, both studies were negative. The initial radiograph was negative in 13 patients and positive in 29. Many foci shown by the radionuclide image were negative on the radiograph, particularly in the tarsal region. Thus stress fractures are often multifocal and may remain radiographically negative.

The Role of Exercise in the Treatment of Osteoporosis

“…In osteoporosis, the structural failure and stress fracture that result in severe pain without dislocation of the involved bone structures can be visualized on bone scan [33] or MRI. Inguinal or anterior groin pain is the earliest and most frequent symptom of a stress fracture of the femoral neck.…”

Fatigue of mineralized tissues: Cortical bone and dentin

“…The importance of understanding the response of mineralized tissues to cyclically applied fatigue loading was recognized roughly half a century ago in the work of Evans and Lebow on human cortical bone (Evans and Lebow, 1957). This is because although most clinical human bone fractures are the result of a single overload, or dynamic, fracture event, there is clinical significance for fractures which occur over time (i.e., stress fractures) as a result of periods of cyclic and/or sustained loading (Meurman and Elfving, 1980;Burr, 1997;Iwamoto and Takeda, 2003;Taylor, 2003). Stress fractures are a well recognized clinical problem with incidence rates of 1%-4% often being reported (Burr, 1997;Taylor, 2003), with even higher rates cited for adolescent athletes and military recruits (Meurman and Elfving, 1980;Iwamoto and Takeda, 2003;Taylor, 2003).…”

They are commonly seen within a few weeks of a sudden systematic increase in the loading patterns experienced by the bone, when the time elapsed is insufficient for an adaptational response to alleviate the deleterious effects of the increased stress levels (Taylor, 2003).…”

Three-phase radionuclide bone imaging and magnetic resonance imaging detection of occult knee fractures in athletes

“…Radionuclide bone imaging provides the earliest sign of an osseous lesion and may easily depict other sites of increased uptake [10][11][12]. MRI yields specific diagnostic information not only about bones but also about soft tissue and endoarticular structures [13][14][15][16][17].…”
