Proximal Median Nerve Compression: Pronator Syndrome

Area of Science:

• Neurology
• Orthopedic Surgery

Background:

• Pronator syndrome (PS) involves median nerve compression in the proximal forearm.
• Symptoms frequently mimic carpal tunnel syndrome (CTS), complicating diagnosis.
• Electrodiagnostic studies for PS can be inconclusive.

Purpose of the Study:

• To highlight the diagnostic challenges of pronator syndrome.
• To review current management strategies, including surgical interventions.
• To emphasize the importance of understanding median nerve anatomy for diagnosis and treatment.

Main Methods:

• Review of clinical findings and diagnostic considerations for PS.
• Discussion of nonsurgical and surgical treatment options.
• Analysis of outcomes data from retrospective case series.

Main Results:

• Accurate diagnosis of PS is often difficult due to symptom overlap with CTS and limitations of electrodiagnostic tests.
• Nonsurgical management is the initial approach for all patients.
• Surgical intervention demonstrates satisfactory outcomes for pronator syndrome.

Conclusions:

• A comprehensive understanding of median nerve anatomy and potential compression sites is crucial for diagnosing pronator syndrome.
• Clinicians must be aware of characteristic clinical findings to differentiate PS from other neuropathies.
• Effective diagnosis and treatment, including surgical options, lead to favorable patient outcomes.
