Managing femoral head osteonecrosis in patients with sickle cell disease.

With an increasing number of people immigrating between different countries, sickle cell disease (SCD) is spreading all over the world. Due to improved health care, the life span of SCD patients has increased and many of them live to adulthood and middle-age. Osteonecrosis of the femoral head is one of the most common musculo-skeletal problems in SCD patients.

Total hip replacement in sickle cell disease.

We report on 35 total hip replacement arthroplasties in 28 patients with avascular necrosis of the femoral head secondary to sickle cell disease (SCD). There were 15 men and 13 women with a mean age of 27.5 years.

The value of ultrasound and aspiration in differentiating vaso-occlusive crisis and osteomyelitis in sickle cell disease patients.

We have studied 50 patients with sickle cell disease who presented with musculoskeletal pain over a 2-year period to assess the use of ultrasound in differentiating infection from infarction. All the patients were evaluated by ultrasound. Five had soft tissue oedema and no fluid collection adjacent to the bone.
