Long term bisphosphonate use has been associated with "atypical" subtrochanteric and diaphyseal fractures of the femoral shaft. We are reporting a case of pelvic fractures in addition to atypical long bone fractures, in a patient with osteopenia treated with bisphosphonate for 8 years, and teriparatide for 2 years. After 5 years of bisphosphonate therapy the patient suffered an atraumatic fract...

The emergence of a new variant of subtrochanteric stress fractures of the femur, affecting patients on oral bisphosphonate therapy, has only recently been described. This fracture is often preceded by pain and distinctive radiographic changes (lateral cortical thickening), and associated with a characteristic fracture pattern (transverse fracture line and medial cortical spike). A retrospective...

It is recommended that full-length femoral radiographs should be obtained in patients presenting with a femoral neck fracture and a co-existent history of malignancy. Over a two-year period, we identified 133 (47 males, 86 females) patients admitted with a femoral neck fracture and a co-existent history of malignant disease, representing 6.5% of all femoral neck fractures admitted within this t...

Rheumatoid arthritis (RA) is a systemic autoimmune disorder which can affect all of the synovial joints including the cervical spine. Cervical involvement typically begins early in the disease process and shows relatively slow progression. Fractures of the odontoid process are mainly noted after a major trauma to the cervical spine. A case of a 77-year-old woman with paresthesia of the extremit...

A 62-year-old man presented with the acute, atraumatic onset of pain 3 years after uncemented right total knee arthroplasty. He complained of new mechanical locking with the knee held in extension on examination and unable to flex the knee. On the plain radiographs, the patellar component peg was fractured and the plate was dislocated. The knee was immobilized, and revision to a cemented 3-peg ...

Atraumatic patellar fractures after Total Knee Arthroplasty (TKA) are rare in unresurfaced patella. Previous reports are few and have highlighted association of these fractures with rheumatoid arthritis and gout along with interference with patellar blood flow after lateral release and Hoffas’ fat pad excision. We report a case of insufficiency fracture of patella in a patient following TKA aft...

Cases of osteonecrosis of the jaw, insufficiency fractures and atypical low energy or atraumatic fractures of pelvis, femur (subtrochanteric/mid-shaft/distal-third), tibia, fibula, metatarsal, humerus, and ulna related to long-term bisphosphonate therapy have been reported in the literature. We present the case of an acute nontraumatic clavicle fracture, associated with long-term bisphosphonate...
