BACKGROUND Slipped capital femoral epiphysis (SCFE) is a frequent disorder of the adolescent hip, which may lead to avascular necrosis (AVN) of the femoral head, chondrolysis and early osteoarthritis due to the post-slip deformity of the proximal femur. To warrant the best possible outcome for the affected (and contralateral) hip, early diagnosis and proper treatment are needed. METHODS A rev...

Subluxation of the hip presenting for the first time in a child over the age of four years is rare. We report ten cases treated over nearly 11 years by the senior author (JAF). We describe the surgical procedures and the results, at maturity, of nine of the ten patients. At a mean follow-up of nearly nine years, the clinical outcome was good in all ten children by the criteria of Ponseti. Radio...

In the United States, renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and 90-95% of all neoplasms arising from the kidney. According to the National Cancer Institute, 58 240 new cases and 13 040 deaths from renal cancer will occur in 2010. RCC usually occurs in older adults between the ages of 50 and 70 and is rare in young adults and children. We describe a case ...

A female patient developed avascular necrosis of the femoral heads after receiving low doses of glucocorticosteroids (GC) for 3 months. Genotyping of the GC receptor (GR) showed that she was heterozygous for the Bcl-1 allele and heterozygous for the N363S allele. Interestingly, these GR variants are both associated with higher sensitivity to glucocorticoids. It is not known whether the GR gene ...

A case of aseptic necrosis of the medial segment of the clavicle with X-ray images of fragmentation and few clinical symptoms is presented. This condition develops spontaneously and leads to early sternoclavicular osteoarthritis. The benign nature of the disease and the absence of treatment make it important to establish the correct diagnosis, differentiating it from other disorders in this area.

kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. this report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. after a short period of casting, the case was fully recovered within one year. the signal change w...
