Abstract

Introduction At least 25% of knee dislocations are associated with common fibular nerve injury. Usually diagnosis is based on clinical and neurophysiological findings. We assessed the role of nerve ultrasound in common fibular nerve injury. Materials and Methods Eight consecutive patients (6 men and 2 women, mean age 34 years) with knee luxation referred to our lab underwent clinical, neurophysiological, and ultrasound examination. Results In all patients we observed a similar pattern: severe weakness (plegia or severe paresis), neurophysiological involvement of both fibular nerve branches and ultrasound evidence of increased fibular nerve area with hypoechogenicity. On follow-up evaluation, 6 patients remained stable, and 2 patients improved. The greater the ultrasound fibular nerve enlargement the worse the recovery. Discussion Nerve ultrasound was confirmed to be a useful diagnostic/prognostic tool in traumatic nerve lesions. A prompt US examination of the fibular nerve should be considered after any case of knee dislocation. © 2014 Wiley Periodicals, Inc.
