Complications of atypical femur fractures (AFFs) are common. AFFs often receive the same treatment as other femoral fractures; however, there appears to be a higher rate of adverse outcomes. Nine patients sustained a total of 13 AFFs, had documented bisphosphonate use before fracture, and had surgery between 2006 and 2012. Complications included continued pain, surgical revision, nonunion, malunion, deformity, or heterotopic ossification. The overall complication rate was 33.3%, with four of the 12 surgeries performed at this institution resulting in one nonunion and three minor complications...

There still remains controversy on the pathomechanism of atypical femoral fracture (AFF). The angle of lateral bowing and bone mineral density showed significant differences between subtrochanteric and diaphyseal atypical fracture groups. In addition to the use of bisphosphonate, mechanical factors might play important roles in the occurrence of AFFs. INTRODUCTION: Although AFF could be divided into subtrochanteric and diaphyseal fracture according to the location of fractures, there is a lack of evidence regarding differences between two fractures and etiology of the occurrence...

The prevention as well as the treatment of atypical femur fractures (AFFs) remains controversial but there have been many clinical recommendations suggested. We have summarized these recommendations as well as expanded upon them in this paper. INTRODUCTION: The purpose of the paper was to develop a clinical practice guideline that both treats AFF and decreases the risk of AFF in patients requiring antiresorptive medications. Examples of these medications include bisphosphonates and denosumab for the treatment of osteoporosis...

Bisphosphonate use has declined dramatically in recent years, partly because of fear of rare side effects like atypical femur fractures (AFFs). It is therefore desirable to have a diagnostic method to identify those at risk of AFF to prevent this serious complication. We compared trabecular microarchitecture and hip geometry between 30 patients with AFF and 141 controls of similar age and sex, using bisphosphonates. Trabecular bone score (TBS) and hip structural analysis (HSA) were used to assess trabecular microarchitecture and macroscopic hip geometry from dual-energy X-ray absorptiometry images of the lumbar spine and hip, respectively...

Atypical femoral fractures (AFFs) occur in both osteoporosis patients and cancer patients who receive long-term bisphosphonate treatment. Denosumab offers an alternative approach for the treatment of bone metastases. We describe a 59-year-old woman with a history of breast carcinoma and bone metastasis who was prescribed denosumab for 4 years. The patient had no history of any prior bisphosphonate use. Bone scintigraphy showed an abnormal uptake in the right femur, which was confirmed as an impending AFF or atypical femoral stress reaction...

We report the case of a 55-year-old woman who presented to the emergency department having woken from sleep with right sided thigh swelling. Pelvic radiographs revealed bilateral atypical subtrochanteric femoral fractures (ASFFs). In the two years leading up to this admission, the patient had experienced gradually increasing pain and weakness in her legs which had resulted in a decrease in her mobility from fully mobile to bed-bound. During this time a neurologist had organised a magnetic-resonance imaging (MRI) scan of the brain and spine which was normal...

Hypophosphatasia (HPP) is a congenital, rare and heterogeneous bone disorder, characterized by a deficit of calcified tissue mineralization, leading to skeletal deformities and osteomalacia in adults, rickets in infants and children, and fragility fractures and premature loss of dentition in children and adults. The disease is caused by a reduced or absent expression and activity of the tissue non-specific alkaline phosphatase (TNSALP) enzyme, derived from inactivating mutations of the alkaline phosphatase ( ALPL ) gene...

Modern osteoporosis treatment began in the mid-1990s with the approval of amino-bisphosphonates, anti-resorptive agents that have been shown to decrease osteoporotic fracture risk by about half. In 2005, the first cases of atypical femoral fractures (AFF), occurring in the shaft of the femur, were reported. Since then, more cases have been found, leading to great concern among patients and a dramatic decrease in bisphosphonate prescribing. The pathogenesis and incidence of AFF are reviewed herein. Management and an approach to prevention or early detection of AFF are also provided...

Atypical Femoral Fractures (AFF) represent fractures located between the lesser trochanter and the supracondylar flare of a femur. An increasing pool of evidence supports their association with the prolonged use of bisphosphonates, even though a direct correlation is yet to be proved. The purpose of this review is to encapsulate the current evidence associating bisphosphonate use and the development of AFFs, the clinical features related to their presentation, as well as to report the armamentarium of strategies available in the prevention and treatment of AFFs...

Background: Osteoporosis is a common condition among the elderly population, and is associated with an increased risk of fracture. One of the most common fragility fractures involve the distal radius, and are associated with risk of subsequent fragility fracture. Early treatment with bisphosphonates has been suggested to decrease the population hip fracture burden. However, there have been no prior economic evaluations of the routine treatment of distal radius fracture patients with bisphosphonates, or the implications on hip fracture rate reduction...

Atypical insufficiency fracture of the femur following prolonged bisphosphonate use is well described. Regardless of the cause, insufficiency fracture of the acetabulum is extremely rare, and no reports have described insufficiency fractures of the acetabulum that are associated with prolonged bisphosphonate use. This report demonstrates the possibility of insufficiency fracture at the acetabulum following long-term alendronate use and the necessity of particular care in managing insufficiency fractures in "frozen" bone...

Context: Denosumab, an inhibitor of receptor activator of nuclear factor κ-B ligand, is an approved treatment of giant cell tumor of bone (GCTB) in adults and "skeletally mature" adolescents. Safety concerns include oversuppression of bone remodelling, with risk of osteonecrosis of the jaw (ONJ) and atypical femur fractures during treatment in adults and rebound hypercalcemia after treatment cessation in children. To date, ONJ has never been reported in children or adolescents...

Antiresorptive drugs, such as amino-bisphosphonates and denosumab (Dmab), have dominated osteoporosis therapies for over 20 years. Since osteoporosis is a chronic disease, antifracture therapy could continue for the rest of a patient's life. Phase III clinical trials for antiresorptive drugs assessed relatively small patient populations for short durations and excluded up to 80% of patients who might seek osteoporosis therapy in clinical practice. Postmarketing reports based upon millions of patient-years and long-term (>5 years) clinical administration have associated some previously unknown, rare adverse events with antiresorptive use including osteonecrosis of the jaw (ONJ) and atypical femur fractures (AFFs)...

BACKGROUND: Although atypical femoral fracture (AFF) occurs more frequently in patients taking bisphosphonates and longer treatment is associated with higher risk, the causal relationship between AFF and bisphosphonates has not been established. Most patients with AFF have osteoporosis that is being treated with bisphosphonates, but we are not aware of any reports regarding the areal bone mineral density (aBMD) and discordance between the T-scores of the femur and spine in such patients...

Little evidence is available on how to treat incomplete atypical fractures of the femur. When surgery is chosen, intramedullary nailing is the most common invasive technique. However, this approach is adopted from the treatment of other types of ordinary femoral fracture and does not aim to prevent the impending complete fracture by interrupting the mechanism underlying the pathology. We suggest a different surgical approach that intends to counteract the underlying biomechanical conditions leading to a complete atypical fracture and thus could be better suited in selected cases...

Atypical femur fractures as a result of long term bisphosphonate use are characterized by several unique radiographic features. We describe an atypical femur fracture treated by cephalomedullary nail with a previously undescribed segmental fracture pattern. Other than 1.5 years of bisphosphonate use the patient did not have any other risk factors known to cause atypical femur fractures. Judicious bisphosphonate use as well as increased awareness of the associated complications may help reduce the rate of bisphosphonate associated atypical femur fractures...

Atypical femoral fractures (AFFs) are recently observed as a complication of long-term bone-modifying agent (BMA; bisphosphonate or denosumab) therapy for bone metastases. We describe the cases of two women diagnosed with breast cancer who developed incomplete AFF associated with BMAs prescribed for bone metastases. Radiographs of their femurs revealed thickening of the lateral subtrochanteric cortex, and tomosynthesis revealed a visible fracture line in the thickened cortex. They were initially treated with conservative management; however, the incomplete fracture resulted in a complete fracture...
