Description
Summary:AbstractAnterior tarsal tunnel syndrome is a relatively unique diagnosis and not encountered with the frequency of other entrapment neuropathies, especially in relation to anterior plating for ankle arthrodesis. To our knowledge, there are no published reports of anterior tarsal tunnel syndrome as a complication of ankle fusion via anterior plating. The location of the deep peroneal nerve (DPN) within the anterior tarsal tunnel makes it susceptible to potential injury when using anterior ankle incisional approaches. Appropriate evaluation is vital in reaching diagnosis and surgical planning. While magnetic resonance imaging (MRI) is the most common imaging modality used today, high frequency ultrasound has distinct advantages for assessing neuropathies about the foot and ankle. This includes higher spatial resolution and capabilities for dynamic and vascular assessments. The primary aim of our study is to raise awareness of DPN injury with anterior approach and plating to ankle arthrodesis as there is limited literature discussing the risk of this complication. As anterior ankle plating has become more popular over the years, it is important to note potential injury or complications to the DPN given the proximity to the arthrodesis site. The secondary aim of our study is to discuss the diagnostic approach to evaluating nerve entrapments, specifically in using high frequency musculoskeletal ultrasound.
