Entrapment neuropathies of the upper extremities

Area of Science:

• Neurology
• Orthopedics
• Sports Medicine

Background:

• Nerve compression disorders in the arm are numerous, with varying prevalence and etiologies.
• Localized inflammation can be as significant a cause of neuropathy as compression in some cases, such as pronator syndrome and anterior interosseous syndrome.
• Understanding these conditions is crucial for specific populations, including musicians and athletes.

Purpose of the Study:

• To illustrate the range of nerve compression syndromes affecting the arm.
• To highlight the importance of these disorders for individuals with high upper limb usage.
• To underscore the need for further research into prevention and treatment.

Main Methods:

• Review of approximately a dozen nerve-compression disorders affecting the arm.
• Selection of three representative syndromes to illustrate common problems.
• Discussion of etiologies, including compression and inflammation.

Main Results:

• Three common nerve compression syndromes of the arm were detailed.
• The differential diagnosis includes compression and inflammation as causes of neuropathy.
• Syndromes have significant implications for musicians, athletes, and those with repetitive arm use.

Conclusions:

• Nerve compression disorders in the arm present a spectrum of clinical challenges.
• Further well-designed prospective trials are essential for advancing prevention and treatment knowledge.
• Understanding the long-term natural history is key, as prevention is often achievable.
