Recent literature shows an association between long-term bisphosphonate therapy and low-energy fractures of the subtrochanteric femur. It is thought that the pharmacology of bisphosphonates and stress characteristics of the subtrochanteric femur predispose patients on long-term therapy to fracture. There are few reports in the literature of bisphosphonate-associated periprosthetic fractures wit...

This review focuses on the occurrence, imaging and differential diagnosis of insufficiency fractures. Prevalence, the most common sites of insufficiency fractures and their clinical implications are discussed. Insufficiency fractures occur with normal stress exerted on weakened bone. Postmenopausal osteoporosis is the most common cause of insufficiency fractures. Other conditions which affect b...

Subchondral insufficiency fracture of the femoral head (SIFFH) is characterized by acute onset hip pain without overt trauma. It appears as a low intensity band with bone marrow edema on T1-weighted MRI. The most common course of treatment is protected weight bearing for a period of several weeks. Total hip arthroplasty (THA) has been commonly used if the patient does not respond to the initial...

Sacral fractures in elderly patients with associated lumbosacral lesions can be overlooked easily because of vague symptoms and delayed neurological insufficiency. A 70-year-old female and a 73-year-old female presented with delayed neurological insufficiency caused by transverse sacral fracture after minor trauma. Both patients had suffered from lower extremity symptoms with dysuresia and dysc...

BACKGROUND Stress fractures are classified as insufficiency and fatigue fractures. Insufficiency fractures occur when normal stresses are placed on bone with decreased mineralization and elastic resistance; whereas fatigue fractures occur when abnormal forces are applied to normal bone. CASE PRESENTATION We report a case of postpartum bilateral sacral fracture in the absence of documented ost...
