The most important complication following the treatment of congenital dislocation of the hip is avascular necrosis. The potential sequelae that may arise after the onset of avascular necrosis are worse than if the hip remained dislocated. We evaluated 38 hips in which avascular necrosis developed after reduction. The average patient age at the time of reduction was 4.3 years, with a follow up o...

Synonyms for this disease include “avascular necrosis of the femoral head” and “aseptic necrosis of the femoral head”, “Perthes disease” and “Legg Perthes” disease, “osteochon-dritis”, “coxae juvenilis”, “coxa plana” and “idiopathic osteosis”. The terms “avascular/aseptic necrosis of the femoral head” are also used to describe a process of femoral head necro-sis in dogs following traumatic frac...

OBJECTIVE To assess if the Hawkins sign can predict whether or not astragalus fractures of the neck will develop avascular necrosis. It is also assessed whether the occurrence of this complication is related to the displacement of the fracture, soft tissue injury, or delay in the reduction or surgery. The results were compared with those found in the literature. MATERIAL AND METHODS A retrosp...

We describe a patient who developed avascular necrosis of both humeral trochleae after combination chemotherapy for acute lymphoblastic leukaemia. This presented as progressive stiffness of both elbows with little pain. Radiography and MRI confirmed the presence of avascular necrosis at both sites. This region corresponds to a watershed between the medial and lateral vascular arcades which supp...

Sickle-cell disease (SCD) is probably the commonest cause of avascular necrosis worldwide, and its prevalence appears to be rising in developed countries. Avascular necrosis of the humeral head is a common complication but has not been previously studied in detail. We have reviewed 138 patients with SCD for clinical, radiological and functional abnormalities of the shoulder, using a radiologica...

Twenty-six patients with femoral neck fractures were treated by open reduction, cancellous screw fixation and free fibular grafting. The patients were between 14 and 50 years of age. There were 16 old and 10 fresh fractures. Four patients had radiological signs of avascular necrosis before the treatment was instituted. Bony union was achieved in all patients except one, where the failure occurr...

Avascular necrosis of the femoral head (AVN) is an increasingly common cause of musculoskeletal disability, and it poses a major diagnostic and therapeutic challenge. Although patients are initially asymptomatic, AVN usually progresses to joint destruction, requiring total hip replacement, usually before the fifth decade. Avascular necrosis is characterized by osseous cell death due to vascular...

Twenty-two displaced talar neck fractures were treated by open reduction and internal fixation. Four open fractures were operated within 8 hours and 18 closed injuries were treated at an average interval of 13.8 hours after injury. Fractures were classified according to Hawkins' classification into 14 type II, 7 type III and 1 type IV. At an average follow up of 4.4 years, 18 cases obtained exc...

A 58-year-old female developed avascular necrosis of her trapezoid approximately 3 months after undergoing carpometacarpal arthroplasty. The patient was treated conservatively with immobilization and had complete resolution of her clinical symptoms during her year of follow-up. Additionally, radiographic examination showed complete restoration of the height of her trapezoid approximately 1 year...
