Stress Fractures of the Lumbar Spine: Pediculolysis as an Unusual Presentation Variant. Case Report
Abstract
In 1990, Gunzburg and Fraser introduced the term pediculolysis to describe stress fractures of the vertebral pedicles, a rare clinical presentation. Repetitive microtrauma associated with lumbar spine hyperextension and rotational movements is considered a key risk factor for this type of lesion. We report the case of a 22-year-old professional rugby player with a history of left-sided spondylolysiswho presented with an episode of disabling acute low back pain. Radiographic studies revealed a right pedicle fracture of the fifth lumbar vertebra (L5) and contralateral spondylolysis. Magnetic resonance imaging (MRI) showed signs of edema in the left pedicle. Conservative orthopedic management was indicated, with a favorable clinical outcome and return to full sports activity.Downloads
