Treatment of Impacted Greater Trochanter Fracture Post-THR

Initial Diagnostic Approach

• Radiographs are the first-line imaging modality for evaluating periprosthetic fractures and greater trochanter pathology in patients with symptomatic hip prostheses, as recommended by the American College of Radiology 1, 2, 3
• Radiographs help assess periprosthetic fractures, greater trochanter avulsions, and heterotopic ossification, with a focus on fracture detection and characterization 2
• If radiographs are negative or equivocal but clinical suspicion remains high, CT or MRI should be obtained for fracture detection and characterization, according to the American College of Radiology 2
• MRI is particularly valuable as seemingly isolated greater trochanter fractures on radiography frequently have occult intertrochanteric extension, as noted by the American College of Radiology 4

Imaging Considerations

• The American College of Radiology recommends MRI for fracture detection and characterization, especially in cases with occult intertrochanteric extension 4
