Fat embolism syndrome with total hip replacement

Area of Science:

• Orthopedic Surgery
• Trauma Medicine
• Critical Care Medicine

Background:

• Total hip replacement is a common orthopedic procedure.
• Fat embolism syndrome (FES) is a potential, though rare, complication of orthopedic surgery.
• Fulminant FES presents with rapid, severe systemic manifestations.

Observation:

• Two cases of fulminant fat embolism syndrome (FES) following total hip replacement are presented.
• Case 1: Patient experienced severe hypotension and cardiac arrest.
• Case 2: Patient presented with postoperative coma.

Findings:

• Both patients developed severe acute respiratory failure.
• Pulmonary edema was the underlying cause of respiratory failure in both cases.
• Fulminant FES following total hip replacement can be rapidly fatal.

Implications:

• Highlights the critical importance of recognizing fulminant FES in the postoperative period after hip arthroplasty.
• Emphasizes the need for prompt diagnosis and aggressive management of respiratory and hemodynamic compromise in suspected FES.
• Suggests vigilance for FES in patients presenting with unexplained deterioration after hip surgery.
