Legg-Calvé-Perthes disease (LCPD) is an idiopathic osteonecrosis of the femoral head with variable complications and resultant deformity of the femoral head and osteoarthritis. Suggested risk factors are acetabular retroversion, obesity, latitude, hyperactivity, and coagulopathy. The most commonly applied classification is based on radiolucency in the lateral pillar of the femoral head, which i...

subchondral insufficiency fracture of the femoral head (siffh) is characterized by acute onset hip pain without overt trauma. it appears as a low intensity band with bone marrow edema on t1-weighted mri. the most common course of treatment is protected weight bearing for a period of several weeks. total hip arthroplasty (tha) has been commonly used if the patient does not respond to the initial...

conclusion the prevalence of radiological parameters associated with fai is high, even in an asymptomatic young population. this high frequency of features may suggest that the threshold values have been set too low in the current literature, or that these findings may reflect anatomical variation rather than true pathological abnormalities. background femoroacetabular impingement (fai) is one ...

background: some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. it happens since the geometry of the proximal femur determines how a force is applied to its different parts. in this study, we have compared proximal femur’s geometric characteristics in femoral neck (fnf), intertrochanteric (itf) and subtrochanteric (stf)...

Introduction: Avascular necrosis (AVN) of the femoral head is a leading cause of end-stage joint disease in the young population that can conduct patients to total hip replacement in early life. There are various risk factors including, trauma, corticosteroids, thrombosis, hypertension, and alcohol. There is a growing number of femoral head AVN patients with a history of self-medication with he...

Preserving femoral head vascularity during hip resurfacing may avoid femoral neck fractures and late femoral loosening. The posterior approach and notching of the femoral neck influence femoral head perfusion. However, it is not known if standard preparation of the femoral head during hip resurfacing can disrupt blood flow. Ten patients (10 hips) with advanced osteoarthritis having metal-on-met...

Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...

conclusions this phenomenon has been reported as a rare complication of septic arthritis and osteomyelitis. treatment of these patients is controversial and the long term results are unknown but efforts must be done for early diagnosis and anatomic reduction of femoral epiphysis. introduction slipped capital femoral epiphysis (scfe) is one of the complications of septic arthritis that occurs ra...
