Introduction (what they are)[edit | edit source]
Bone Stress Injures occur when the bone stresses applied during activity, like running, exceed the bone's tissue tolerance. They most commonly occur in competitive cross-country runners and track-and-field athletes. [1]
Mechanism of Injury[edit | edit source]
With an increase in external mechanical factors, there are adaptive changes in internal architecture. With the increased load, a stress reaction would occur with the presence of periosteal edema. A bone stress fracture would be indicated by a cortical fracture line on the MRI. [1]
Bones have a stronger compressive tolerance, and have a greater conservative recovery.
One mechanism indirectly related to running, but relating to athlete health, are gonadal hormone irregularities, which can cause athletes to have cortical and trabecular BSIs and/or osteopenia or osteoporosis. This can also occur in athletes with nutritional imbalances, hormonal influences, and decreased bone mineral density. [1]
Risk Factors and Prevention[edit | edit source]
With mitigating or preventing risk factors of BSIs, healing times and overall bone health can be improved for runners.
There are two types of risk factors that can be considered for BSIs: factors that alter the load applied to the bone, or factors that influence the bone's ability to withstand load, thus minimising damage. The factors that alter the load stem from the size, frequency, duration, and direction of the load applied to the bone.
Diagnosis[edit | edit source]
BSIs can be detected from MRIs of periosteal edema as well as differing levels of bone marrow edema. More severe injuries may be indicated by a cortical fracture line on the MRI. [1]
Upon noticing these symptoms, early identification and management would lead to better prevention of further injury. [1]
