[Induced hyperlipemia test during femur head osteonecrosis]

Area of Science:

• Orthopedics
• Metabolic research
• Hepatology

Background:

• Aseptic osteonecrosis of the femoral head is a debilitating condition.
• Lipid metabolism disturbances are increasingly recognized as potential contributing factors in various diseases.
• Fatty degeneration of the liver and ethylism are common comorbidities.

Purpose of the Study:

• To investigate disturbances in lipid clearance in patients with aseptic osteonecrosis of the femoral head.
• To assess the relationship between impaired lipid clearance and comorbidities like fatty liver disease.
• To explore the etiological role of lipid metabolism anomalies in femoral head osteonecrosis.

Main Methods:

• An induced intravenous hyperlipemia test was employed to assess lipid clearance.
• The study included 19 patients diagnosed with aseptic osteonecrosis of the femoral head.
• Patient data on comorbidities such as ethylism and fatty liver degeneration were collected.

Main Results:

• A significant decrease in the coefficient of lipid clearance was observed in all 19 patients.
• Impaired lipid clearance was more pronounced in patients with coexisting fatty degeneration of the liver.
• Ethylism and fatty liver degeneration were frequently noted in the patient cohort (13 out of 19).

Conclusions:

• Disturbances in lipid clearance are prevalent in aseptic osteonecrosis of the femoral head.
• Fatty degeneration of the liver exacerbates lipid clearance impairment in these patients.
• These lipid metabolism anomalies, alongside factors like corticotherapy, warrant consideration in the etiology of femoral head osteonecrosis.
