Looser zone

Case contributed by Maulik S Patel
Diagnosis probable

Patient Data

Gender: Female
x-ray

Radiograph of the pelvis shows a focal lucency along the inner margin of the femoral neck. The lucency is oriented perpendicular to the cortex, and does not span the entire cross-section of the femoral neck (as a typical fracture would). There is also minimal sclerosis associated with the lesion (unlike a typical stress fracture).

Case Discussion

One of several classic locations for a looser zone.
