Park JH, et al. - Researchers here evaluated the proportion of greater trochanter (GT) fractures with occult extension to the intertrochanteric region on magnetic resonance imaging (MRI) among apparently isolated GT fractures. They also investigated the use of MRI for formulating a treatment strategy in patients with isolated GT fractures. In 38% of apparently isolated GT fractures on radiography, hidden intertrochanteric fractures were identified with MRI. Findings thereby indicated the utility of MRI in the evaluation of apparently isolated GT fractures to diagnose the extent of the occult fracture and determine the treatment strategy.
