This case report describes a 46-year-old male runner who reported the sudden onset of right hip pain. A diagnosis of trochanteric bursitis was established by a physiatrist, and the patient underwent two courses of physical therapy for moist heat, ultrasound, and exercise. Because minimal improvement was seen in the patient's...

Insufficiency fracture is a subgroup of stress fracture. Unlike the other subtype (ie, fatigue fracture), insufficiency fracture is caused by normal or physiologic stress upon weakened bone. Loss of bone trabeculae decreases the bone's elastic resistance.
Awareness is increasing concerning the occurrence of these fractures among older persons. Sites frequently affected...

Acetabular retroversion (AR) alters load distribution across the hip and is more prevalent in pathologic conditions involving the hip. We hypothesized the abnormal orientation and mechanical changes may predispose certain individuals to stress injuries of the femoral neck. We retrospectively reviewed the anteroposterior (AP) pelvic radiographs of 54 patients (108...

High-impact physical activity in adolescent girls, especially basketball, running, and gymnastics/cheerleading, may increase the risk for stress fractures, according to the results of a prospective cohort study reported online April 4 and will appear in the August print issue of the Archives of Pediatrics & Adolescent Medicine.
High-Impact Sports May Increase...

Conclusions: Results suggest that strain magnitude plays a more important role in stress fracture development than the total number of loading cycles. Runners wishing to decrease their probability for tibial stress fracture may benefit from a 10% reduction in stride length.

A rare case of multilevel transverse process stress fractures as a cause of low back ache in a professional cricket player has been presented. The report discusses the possible mechanism of such an injury in a cricket player and also highlights the preventive and therapeutic aspects of management in such...

Bone self-repair and self strengthening involves first osteoclastic activity to take down the inappropriate microstructure and followed by osteoblastic activity to lay down the matrix, which will ossify to become the new, mechanically appropriate bone architecture. During this process, the bone is temporarily vulnerable to the mechanical stress, if it...

Stress fractures are overuse injuries of bone. These fractures, which may be nascent or complete, result from repetitive subthreshold loading that, over time, exceeds the bone's intrinsic ability to repair itself. Briefhaupt originally described stress fractures in military recruits in 1855. Our present understanding of the pathophysiology of stress fractures...

Background: Stress fractures refers to the failure of the skeleton to withstand submaximal forces over time.
Two entities of stress fracture have been defined. Fatigue fracture is classically described in military recruits and runners...

Stress ("march") Fracture, 3rd Metatarsal The only radiographic abnormality detected is subtle periosteal reaction in the diaphysis of the 3rd left metatarsal. No bone destruction is evident. No fracture is seen. Radiographic findings in a patient with clinical history of "being on his feet a lot" suggest stress fracture of the...

Stress fractures are injuries that result from overuse. They are typically associated with muscle fatigue leading to decreased support of bony architecture. An estimate of the incidence of stress fractures in athletes and military recruits is 5-30%.

A stress fracture is an overuse injury. It occurs when muscles become fatigued and are unable to absorb added shock. Eventually, the fatigued muscle transfers the overload of stress to the bone causing a tiny crack called a stress fracture.
