Upper Extremity Nerve Entrapment Syndromes

Peripheral Nerve Entrapment Syndromes in the Upper Extremity: Diagnosis and Management

Peripheral nerve entrapment syndromes are a common cause of upper extremity pain and dysfunction 1. These syndromes occur when peripheral nerves are compressed or irritated. This article explores the diagnosis and management of three such syndromes: cubital tunnel syndrome, radial tunnel syndrome, and pronator syndrome. We will examine conservative and surgical treatment options and discuss the role of electrodiagnostic studies in their diagnosis.

Cubital Tunnel Syndrome

Cubital tunnel syndrome, also known as ulnar neuropathy at the elbow, arises from ulnar nerve compression or irritation as it passes through … Read more

Chapter 29 Electrodiagnostic Studies

Electrodiagnostic studies, such as nerve conduction studies (NCSs) and electromyography (EMG), are powerful tools for evaluating nerve and muscle health. They help pinpoint the location and severity of various conditions, from nerve damage (neuropathies) to muscle disorders (myopathies).

NCSs measure how fast electrical signals travel through your nerves. By stimulating nerves and recording their responses, doctors can identify problems with nerve function. There are two types of NCSs: motor and sensory. Motor NCSs assess the nerves that control muscle movement, while sensory NCSs evaluate nerves responsible for sensations.

EMG takes a closer look at muscle activity. A small needle is … Read more
