Hip Fracture in Emergency Medicine Workup

Laboratory Studies
- Laboratory studies are not useful in the diagnosis of fracture. Preoperative laboratory studies usually are drawn.
Imaging Studies
- Anteroposterior (AP) and lateral views demonstrate most fractures.
- If a fracture is not obvious, look for alteration of the Shenton line and compare it to the other hip. In addition, check the neck-shaft angle, which is determined by measuring the angle created by lines drawn through the centers of the femoral shaft and femoral neck. This should be approximately 120-130°.
- For patients in whom femoral neck fracture is strongly suspected but standard x-ray findings are negative, an AP view with internal rotation provides a better view of the femoral neck.
- If radiographic findings are equivocal but the history and physical examination are concerning for fracture, CT scan should be considered, particularly in unstable patients or those for whom MRI would be significantly delayed. A recent retrospective study has questioned the sensitivity of plain radiography in detecting hip and pelvis fractures.[13]
- MRI and bone scan
- If standard radiograph findings are negative and hip fracture still is strongly suspected, MRI and bone scan have high sensitivity in identifying occult injuries.
- MRI is 100% sensitive in patients with equivocal radiographic findings.
- Traditionally, bone scan has been thought to be unreliable before 48-72 hours after fracture, but one study found a sensitivity of 93% regardless of time from injury, including fractures less than 24 hours old.
- For patients in whom a fracture is strongly suspected and radiographs are negative, consider admission if MRI or bone scan is not readily available.
