Insufficiency fracture

Insufficiency fractures are a type of stress fracture, which are the result of normal stresses on abnormal bone. Looser zones are also a type of insufficiency fracture. They should not be confused with fatigue fractures which are due to abnormal stresses on normal bone, or with pathological frac...

Fatigue fracture

Fatigue fractures (also known as overuse fractures) are a type of stress fracture due to abnormal stresses on normal bone. They should not be confused with an insufficiency fracture, which occurs due to normal stresses on abnormal bone. Plain radiographs typically demonstrate a linear sclerotic ...

Atypical femoral fracture

Atypical femoral fracture also known as bisphosphonate-related proximal femoral fractures are an example of insufficiency fractures, although the direct causative link remains somewhat controversial 2. The atypical fracture pattern occurs in the femur shaft and may be unilateral or bilateral. ...

Pathological fracture risk (Mirels classification)

Mirels classification is a system used to predict the highest risk of pathological fracture among long bones affected by metastases, and is based on site, location, matrix and/or presence of pain.  Classification 1 point upper limb involving <1/3 of bone diameter blastic/sclerotic lesion m...
