Non-traumatic radiation-induced avascular necrosis of the femoral neck.
Femoral head avascular necrosis (AVN) is bone destruction due to subchondral oxygen deficiency and necrosis. Our patient is a 63-year-old man with Gleason score 5+4 prostate cancer. He received external beam radiation therapy (7200 cGy) along with combined androgen blockade therapy of lupon/casodex. The patient was complaining of bone pain and on a surveillance NaF18-PET/CT to rule out prostate...
متن کاملNon-traumatic avascular necrosis of the femoral head.
We used technetium-99m antimony colloid to visualize the bone marrow of the head of the femur within twenty-four hours after interruption of the blood supply by subcapital osteotomy and section of the ligamentum teres in thirteen rabbits and within twenty-four hours after a subcapital fracture in thirty patients. Of the rabbits, all showed loss of marrow radioactivity over the affected femoral ...
متن کاملAvascular Necrosis of the Femoral Head: Are Any Genes Involved?
Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...
متن کاملEarly prediction of femoral head avascular necrosis following neck fracture.
Femoral neck fracture puts at risk functional prognosis in young patients and can be life-threatening in the elderly. The present study reviews methods of femoral head vascularity assessment following neck fracture, to address the following issues: what is the risk of osteonecrosis? And what, in the light of this risk, is the best-adapted treatment to avoid iterative surgery? Femoral head vascu...
متن کاملRotational osteotomy for non-traumatic avascular necrosis of the femoral head.
We reviewed 41 hips in 40 patients at three to 11 years (average 6.3 years) after Sugioka transtrochanteric rotational osteotomy for non-traumatic avascular necrosis of the femoral head. The clinical results were excellent or good in 23 hips (56%) and the radiological success rate was 56%. Failure was due to fracture of the femoral neck, nonunion of the osteotomy, secondary collapse, or osteoar...
