Stress Fracture eMedicine PMR
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 and of bone's response to loading has been advanced by numerous studies investigating the epidemiology of stress fractures in military recruits and in athletes.
Stress fractures most commonly occur in the lower limbs as a result of the ground-reaction forces (GRFs) that must be dissipated during running, walking, marching, or jumping. Stress fractures of the vertebral arch, upper limbs, ribs, and even the scapula have also been described and are not uncommon in some sports.

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 in which normal bone is exposed to repeated abnormal stresses. In insufficiency fracture, normal stress is applied to abnormal bone (eg, bone with osteoporosis or Paget disease).

Stress Fracture Patient Information AAOS
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.

The stress fracture is a common overuse injury seen in athletes and military recruits. The injury is usually seen in the lower extremities, but it has also been reported in the upper extremities and ribs. The most common locations for stress fractures include the tibia, metatarsals, fibula, and navicular bones. Less common locations include the femur, pelvis, and sacrum.
