Obesity and Its Relationship With Pelvic and Lower-Extremity Orthopedic Trauma

Obesity has been increasing steadily in the US population over the past 50 years. In trauma patients, obesity is associated with higher morbidity and mortality. There are reported increases in the incidence of cardiovascular, pulmonary, venous thromboembolic, and infectious complications in obese trauma patients. Obese patients who sustain high-energy traumatic injuries often sustain orthopedic injuries to the pelvis or lower extremities. Obese orthopedic trauma patients may be at higher risk for nerve injuries secondary to positioning, intraoperative complications, loss of reduction after surgery, increased intraoperative estimated blood loss, and increased operative times. Orthopedic surgeons must be aware of these results when treating these fractures in obese trauma patients.
