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...

Avascular necrosis (AVN) of the proximal femoral epiphysis is an iatrogenic complication of treatment for developmental dysplasia of the hip (DDH), and does not occur during the natural history of the untreated hip. The objective is to produce a congruous concentric joint and minimize premature degenerative disease and disability during young adult life, by achieving early reduction of the hip ...

Avascular necrosis of femoral head (ANFH) is a common complication affecting about 25% of the patients treated with corticosteroids after kidney transplantation. Patient complains of severe pain, limitation of hip range of motion especially abduction and external rotation, also affect the gait and activity of daily living. The current study was conducted to detect the effect of faradic stimulat...

Twenty-nine patients with avascular necrosis of the femoral head after injury have been treated by operation. Multiple drilling of the femoral head was performed, necrotic bone removed and a muscle-pedicle bone graft implanted into the head and neck of the femur. In 17 of the patients the necrosis was associated with an un-united femoral neck fracture, in 11 it occurred after the fracture had u...

Avascular necrosis is a serious complication of slipped capital femoral epiphysis and is difficult to treat. The reported incidence varies from 3% to 47% of patients. The aims of treatment are to maintain the range of movement of the hip and to prevent collapse of the femoral head. At present there are no clear guidelines for the management of this condition and treatment can be difficult and u...

We report a series of 50 patients under 70 years of age who had an ununited femoral neck fracture treated by a Pauwels abduction osteotomy. At an average follow-up of 7.1 years, seven patients had required prosthetic replacement and 37 others were reviewed in detail. In these patients the Harris hip score averaged 91. Twenty-two hips showed radiographic evidence of avascular femoral head necros...

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...

BACKGROUND The aim of this study was to contrast the collapse values of the postoperative weight-bearing areas of different tantalum rod implant positions, fibula implantation, and core decompression model and to investigate the advantages and disadvantages of tantalum rod implantation in different ranges of osteonecrosis in comparison with other methods. MATERIAL AND METHODS The 3D finite el...

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...
