recognition of relationship between the present day stress state and fractures is very important in fractured reservoirs. fractures that are parallel or oblique to maximum horizontal stress have more tendencies to tensile deformation and tensile deformed fractures will be more permeable. the dalan formation is one of the main gas reservoirs of iran witch most of the production from this formati...

OBJECTIVE To determine clinical characteristics of and outcome in Thoroughbred racehorses with tibial or humeral stress fractures. DESIGN Retrospective study. ANIMALS 99 Thoroughbreds with tibial or humeral stress fractures. PROCEDURE Information obtained from the medical records included history, signalment, and clinical, radiographic, and scintigraphic findings. Outcome was determined b...

Stress fractures, that is fatigue and insufficiency fractures, of the pelvis and lower limb come in many guises. Most doctors are familiar with typical sacral, tibial or metatarsal stress fractures. However, even common and typical presentations can pose diagnostic difficulties especially early after the onset of clinical symptoms. This article reviews the aetiology and pathophysiology of stres...

The aim of this study was to determine the prevalence of self- reported versus diagnosed stress fractures in female elite athletes and non-athletic controls. A random sample of Norwegian elite athletes from the national teams, aged 13-39 years (n = 186) and a random sample of non-athletic controls (n = 145) in the same age group participated in the study. The athletes represented a junior- or s...

conclusions the most relevant finding was that hook pinning in pauwels type iii fracture may result in delayed :union: or non:union: due to significantly increased stress of a traction force at the fracture site that works to displace the fracture. however, in a pauwels type i fracture, increased compression stress contributes to stabilize it. surgeons are recommended not to treat pauwels type ...

The purpose of this study was to investigate the association of stress fractures with age, sex, sport level, sporting activity, and skeletal site in athletes seen at our sports medicine clinic between September 1991 and May 2001. During these 10 years, 10 726 patients (6415 males, 3861 females) visited our clinic because of sport-related injuries, and 196 patients [125 males (1.9%), 71 females ...

Stress fractures result from cyclic overload and usually affect the bones of the lower extremities. These stress fractures occur most often in athletes and in members of the military. These fractures, which are also known as fatigue fractures, are susceptible to repeated trauma and typically involve the metatarsal bones, femur, tibia, fibula, pelvis or spine. The few cases of sacral stress frac...

Stress fractures occur due to repetitive forces on the bones and develop over time. The etiology differs from a traumatic fracture and therefore stress fractures are more an overload injury. Stress fractures of the foot and ankle are frequently seen in athletes and can be a potentially career ending injury for these high demanding sportsmen. Some locations are considered as high‐risk stress fra...

tress fractures occur typically in the lower extremity, caused by impact loading from running, walking, or jumping. In one large series, Matheson and colleagues [1] reported on 320 stress fractures, in which 90% occurred in the lower extremity. However, upper-extremity stress fractures are now being recognized more frequently. These fractures occur either as a result of repetitive loading at th...
