Insufficiency Fracture Following Power Walking

Insufficiency fracture of the unresurfaced patella following total knee arthroplasty

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...

Subtrochanteric Femoral Insufficiency Fracture Following Bisphosphonate Therapy for Osseous Metastases

We present the case of an insufficiency fracture of the femoral shaft in a 61-year-old man who had received bisphosphonate therapy to reduce the fracture risk from lytic renal cell carcinoma metastases to the spine. Approximately 1.5 years after beginning monthly intravenous infusions of zoledronic acid (Zometa), the patient complained of persistent thigh pain. Radionuclide bone scan showed mil...

Parasymphyseal insufficiency fracture.

Osteoporotic sacral insufficiency fracture

Sacral insufficiency fractures (SIFs) are easily neglected by clinical physicians. The incidence of SIFs remains unclear in patients with symptomatic osteoporotic compression fractures of the lumbar-sacral area. This retrospective study was conducted by reviewing the medical records and radiological reports and by reading magnetic resonance (MR) images from August 2013 to July 2016.We identifie...

Insufficiency fracture after radiation therapy

Insufficiency fracture occurs when normal or physiological stress applied to weakened bone with demineralization and decreased elastic resistance. Recently, many studies reported the development of IF after radiation therapy (RT) in gynecological cancer, prostate cancer, anal cancer and rectal cancer. The RT-induced insufficiency fracture is a common complication during the follow-up using mode...
