Abstract
This case presentation offers supportive evidence that shear wave elastography may provide an alternative method of diagnosis of chronic exertional compartment syndrome (CECS). A 39-year-old female runner presented with bilateral anterior shin pain on exertion. She initially underwent compartmental pressure testing confirming the diagnosis of CECS but declined fasciotomy. When her symptoms recurred, she was referred for botulinum toxin therapy. Shear wave muscle elastography was performed in the bilateral anterior and lateral compartments following symptom provocation treadmill testing and compared with 2 control subjects. At 6 weeks and 7 months after onabotulinumtoxinA injections, she was asymptomatic, and elastography measurements revealed a reduction in muscle stiffness from initial treadmill testing.
