Two patients who developed widespread severe avascular necrosis of bone while on steroid replacement therapy are described. One, a diabetic, underwent yttrium-90 pituitary ablation for retinopathy and developed avascular necrosis within 18 months of starting prednisolone. The other, who had Addison's disease, developed avascular necrosis within 14 months of starting cortisol replacement therapy...

Background and purpose - There are limited data on risk factors for avascular necrosis of the hip, but cirrhosis has been proposed as a risk factor. We examined the association between cirrhosis and incidence of total hip arthroplasty for avascular necrosis. Methods - We used nationwide healthcare data to identify all Danish residents diagnosed with cirrhosis in 1994-2011, and matched them 1:5 ...

We studied the pathogenesis, incidence and consequences of avascular necrosis in 184 children treated for congenital dislocation of the hip. Of 210 hips, 99 (47%) had some evidence of avascular necrosis (total 81, partial 18). The incidence was not influenced by the age at reduction, the duration of traction or the use of adductor tenotomy. Patients treated by closed reduction without prelimina...

No consensus regarding optimal treatment or etiology of Preiser disease exists. We described the epidemiology,classification and treatment characteristics of 18 patients with Preiser disease. Patients with changes related to previoustrauma, and without radiographs were excluded. Based on the radiographs at diagnosis, we classified 13 scaphoids asHerbert Lanzetta stage II, four...

Avascular necrosis of the talus after severe ankle injury is well known. Avascular necrosis of talus is extremely rare in juveniles. However, it has been controversial whether the incidence of AVN after fracture of talus is higher in adult than in juveniles. It is possible that the immature talus can be more susceptible to circulatory. As treatment of avascular necrosis of the talus, non-operat...

This report shows a rare case of avascular necrosis of vertebra body after insertion of interspinous device after insertion of interspinous device and its plausible cause. A 82-year-old woman presented with severe back pain for 1 week without injury. In her history, she had undergone decompression and implantation of L4-5 interspinous device for the relief of neurogenic claudication at 4 year a...

Cancer patients have a better prognosis now than in the past. An estimated 66% of patients diagnosed with cancer between 1996 and 2004 were alive at 5 years.1 As patients are living longer after treatment, long-term complications associated with treatment are becoming a greater issue. Avascular necrosis, also referred to as osteonecrosis, ischemic necrosis, subchondral avascular necrosis, asept...

ABSTRACT Total talus dislocation is a rare injury and is commonly accompanied by associated fractures. Common worrisome sequelae are infection, avascular necrosis and post-traumatic arthritis. We report here on a patient who sustained an open total talus dislocation with an ipsilateral medial malleolus fracture. Following early debridement, reduction and a combination of internal and external f...

Avascular necrosis of bone is sometimes a complication of cancer chemotherapy that includes corticosteroids but generally occurs at a single site. A patient with testicular teratoma who received chemotherapy that did not include steroids developed avascular necrosis of the left femoral head, left scaphoid, and both medial femoral condyles. Symptoms were relieved with anti-inflammatory drugs and...

INTRODUCTION Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively. CA...
