Injury of nerve of upper extremity — Clinical Guidelines

Overview

Injury to the nerves of the upper extremity can result from various occupational and recreational activities, leading to significant functional impairment and prolonged recovery periods. These injuries often require specialized rehabilitation and careful management to optimize outcomes and facilitate return to work or activity. 1 2 6 9

Diagnosis

Clinical Examination: Assess motor and sensory function, reflexes, and specific nerve innervation territories.

Electromyography (EMG) and Nerve Conduction Studies (NCS): Essential for diagnosing nerve injuries and assessing severity.

Imaging: MRI or ultrasound to identify structural causes like compression or trauma.

Functional Scoring Systems: Use objective functional scores to monitor recovery progress. 2 3

Management

Rehabilitation Programs: Intensive, specialized hand therapy programs supervised by hand surgeons improve outcomes. 2

Pain Management: Multimodal analgesia including NSAIDs and potentially opioids for acute pain, tailored to individual needs.

Surgical Intervention: Consider for compressive neuropathies or severe traumatic injuries where conservative measures fail.

Psychosocial Support: Address psychological and social factors impacting recovery and return to work. 3

Special Populations

Workers: Focus on occupational rehabilitation programs to enhance return-to-work outcomes. 3

Athletes: Tailored return-to-play strategies considering the nature and severity of the injury. 10

Key Recommendations

Implement specialized interdisciplinary hand therapy programs for optimal functional recovery post-injury. (Evidence: Strong 2)

Incorporate comprehensive psychosocial assessments to identify barriers to recovery and return to work. (Evidence: Moderate 3)

Utilize objective functional scoring systems alongside patient-reported outcomes to guide rehabilitation progress. (Evidence: Moderate 2 3)
