Avascular necrosis (AVN) of the head of the femur is a potentially crippling disease which mainly affects young adults. Although treatment by exposure to hyperbaric oxygen (HBO) is reported as being beneficial, there has been no study of its use in treated compared with untreated patients. We selected 12 patients who suffered from Steinberg stage-I AVN of the head of the femur (four bilateral) ...

A recognized issue related to metal-on-metal hip resurfacings is early fracture of the femur. Most theories regarding the cause of fracture relate to clinical factors but an engineering analysis of failed hip resurfacings has not previously been reported. The objective of this work was to determine the wear volumes and surface roughness values of a cohort of retrieved hip resurfacings which wer...

This case deals with the avascular necrosis or osteonecrosis of the femoral head in a 41-year-old male presenting to a chiropractor's office. In addition to the clinical picture, diagnostic imaging should be performed to confirm the presence and extent of hip avascular necrosis. Referral to an orthopedic specialist is key and treatment is mainly surgical.

stage osteonecrosis of the femoral head (ONFH), the factors normally considered are the progression of the disease and the patient’s age. Although most clinicians agree that the focus, when first treating patients under 50 years of age, should be on preserving the joint, there is significant controversy as to the appropriate procedure in any given case. Core decompression is one of the joint sa...

OBJECTIVES The purpose of this study was to review the treatment of patients with ipsilateral acetabular and femur fractures to provide descriptive demographic data, injury pattern classification, treatment, and evaluate the complication profile reflective of current practices. STUDY DESIGN Multicenter retrospective cohort. SETTING Eight Level 1 Trauma Centers. PATIENTS/PARTICIPANTS One h...

Osteonecrosis or avascular necrosis (AVN) is a pathologic process that results from a critical decrease of blood supply to the bone and elevated intraosseous pressure [1]. While the pathogenic process is not clear, it is believed that osteonecrosis is the final common pathway of traumatic and non-traumatic insults and that it impairs blood circulation to the femoral head. Subsequently, interrup...

Fractures of the neck of the femur account for less than 1% of all paediatric fractures. The complications after this injury are very frequent, the most significant being avascular necrosis. Slipped capital femoral epiphysis is a well-known disorder of the hip in children that is characterised by displacement of the capital femoral epiphysis from the metaphysic through the physis. In the vast m...

Results: Sixteen patients with impacted and undisplaced fracture of the neck of femur were treated with multiple cannulated screws. The mean follow up was 26 months; mean age was 38 years (range 14-58 years). Thirteen/16 patients (81.25%) were satisfied with the excellent results of the treatment. Two patients (12.5%) showed nonunion and valgus osteotomy, compression of the fracture and rigid i...
