S44.32
Injury of axillary nerve, left arm
Clinical Classification Guidelines
Medical Intelligence & Overview
An injury to the axillary nerve in the left arm is a type of nerve damage that can affect shoulder movement and sensation. The axillary nerve, which originates from the brachial plexus, plays a crucial role in innervating the deltoid and teres minor muscles, and provides sensation to part of the shoulder. Such injuries may result from trauma, fractures, or other causes, leading to varying degrees of weakness, numbness, or pain in the affected arm and shoulder.
Causes & Symptoms
Clinical Causes: Traumatic accidents, such as falls or car collisions Fractures of the proximal humerus (upper arm bone near the shoulder) Surgical procedures involving the shoulder or upper arm Compression of the nerve due to prolonged pressure or swelling Sports injuries involving direct blows or overextension of the shoulder
Key Symptoms: Weakness in shoulder abduction (lifting the arm sideways) Decreased sensation or numbness over the deltoid muscle area Difficulty in lifting or rotating the arm Pain or discomfort around the shoulder and upper arm Atrophy of the shoulder muscles in severe cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of physical examination and nerve conduction studies. A healthcare provider may assess muscle strength, reflexes, and sensory responses. Imaging tests like X-rays or MRI scans can help rule out fractures or other structural injuries, while electromyography (EMG) may evaluate nerve function to pinpoint the location and extent of the injury.
Treatment Protocols: Treatment options focus on promoting nerve healing and restoring shoulder function. Approaches may include:
