Procedure-oriented sectional anatomy of the shoulder

Area of Science:

• Orthopedics
• Anatomy
• Pain Management

Background:

• Non-imaging-guided needle procedures are common in shoulder treatment.
• Accurate anatomical knowledge is crucial for procedural success and safety.
• Existing anatomical resources may not specifically focus on needle-guided interventions.

Purpose of the Study:

• To provide a detailed anatomical review of the shoulder joint relevant to non-imaging-guided needle procedures.
• To enhance the safety and accuracy of procedures such as glenohumeral injections, suprascapular nerve blocks, and electromyography.
• To present anatomically accurate schematics illustrating key landmarks and potential complication sites.

Main Methods:

• Review of shoulder joint anatomy with a focus on structures relevant to needle entry.
• Development of cross-sectional schematics (axial and sagittal views) of the shoulder.
• Identification and highlighting of superficial and deep anatomical landmarks.
• Analysis of accuracy and potential complications associated with common non-imaging-guided shoulder procedures.

Main Results:

• Detailed anatomical descriptions of the glenohumeral, subacromial, and acromioclavicular joints.
• Illustrations of needle trajectories for various procedures including joint injections, intramuscular injections, and nerve blocks.
• Identification of critical anatomical structures and potential sources of iatrogenic injury.
• Review of reported accuracy rates and common complications (e.g., infection, tendon damage).

Conclusions:

• Accurate, procedure-oriented anatomical knowledge is essential for safe and effective non-imaging-guided shoulder interventions.
• The provided schematics serve as a valuable tool for clinicians performing these procedures.
• Enhanced understanding of shoulder anatomy can minimize complications and improve patient outcomes.
