Thoracic outlet syndrome (TOS) involves nerve and blood vessel compression. Diagnosis relies on clinical evaluation, with conservative management focusing on posture and exercise, while surgery is reserved for persistent cases.

Area of Science:

  • Orthopedics
  • Neurology
  • Vascular Surgery

Background:

  • Thoracic outlet syndrome (TOS) is a complex condition involving compression of neurovascular structures at the thoracic inlet.
  • The existence, diagnosis, and management of TOS remain subjects of significant debate within the medical community.

Purpose of the Study:

  • To provide a comprehensive overview of thoracic outlet syndrome, encompassing its controversial aspects.
  • To outline current diagnostic criteria and management strategies for TOS.

Main Methods:

  • Diagnosis is primarily based on clinical evaluation, including symptom reproduction with specific maneuvers like arm elevation.
  • Absence of other potential pathologies is crucial for confirming the TOS diagnosis.
  • Conservative management focuses on correcting postural abnormalities and muscle imbalances in the cervicoscapular region.

Main Results:

  • Successful conservative management requires patient adherence to home exercise programs and behavioral modifications.
  • Surgical decompression via a supraclavicular approach is indicated for patients unresponsive to conservative treatments.
  • The supraclavicular approach is considered optimal for brachial plexus decompression in TOS.

Conclusions:

  • Thoracic outlet syndrome diagnosis hinges on clinical assessment and exclusion of other conditions.
  • Conservative treatment, emphasizing posture and exercise, is the cornerstone of TOS management.
  • Surgical intervention for TOS should be reserved for refractory cases, utilizing a supraclavicular approach for optimal results.
