Invited Review: Common sports-related nerve injuries seen by the electrodiagnostic medical consultant
FREE MEMBER CME!
Abstract
The high physiologic demands of sports create dynamic stress on joints, soft tissues, and nerves which may lead to injuries in the athlete. Electrodiagnostic (EDx) assessment is essential to identify the correct diagnosis, localization, and prognosis, to guide management of sports-related neuropathies. A comprehensive review was performed to provide the EDx medical consultant with a practical approach to the common peripheral nerve disorders seen in athletes. Sports-related neuropathies reviewed include transient traumatic irritation of the brachial plexus and/or cervical nerve roots (“Burners and stingers,”) suprascapular and axillary neuropathies, ulnar neuropathy at the elbow (UNE) in throwers, ulnar neuropathy at the hand/wrist in cyclists, multi-ligamentous knee injury, and foot/ ankle neuropathies including tarsal tunnel syndrome. A thorough understanding of peripheral anatomy, possible entrapment sites, mechanisms of injury, and key physical examination findings is essential for correct diagnosis. EDx assessments beyond routine studies are generally required for sports-related neuropathy, which may not necessarily follow typical entrapment patterns. Adjunct diagnostic imaging, such as point-of-care ultrasound and magnetic resonance imaging, are helpful tools to identify associated musculoskeletal pathology such as compressive cysts or nerve entrapment, which may be amenable to interventional or surgical treatment. When no clear reversible structural pathology exists, management of sports-related neuropathy is athlete-specific and generally multi-modal, involving a combination of physical rehabilitation techniques to address muscle imbalances, load management, protective equipment, and interventional pain procedures.
Objectives:The objectives of this activity are to: 1) Be able to clinically evaluate patients with suspected sports-related nerve injuries related to cervical nerve roots, and to the brachial plexus, shoulder, ulnar nerve, knee, and the foot and ankle; 2) Understand and apply the findings of electrodiagnostic and imaging studies performed for the evaluation of these sports-related nerve injuries; 3) Understand and apply the basic principles of treatment for these sports-related nerve injuries.
