The functional anatomy of the elbow complex

Area of Science:

• Orthopedics
• Anatomy
• Biomechanics

Background:

• The elbow joint complex comprises the ulna, radius, and humerus, forming four distinct articulations.
• Static stabilization is provided by the osseous structure, ulnar collateral ligament, lateral collateral ligament, and joint capsule.
• Dynamic stabilization and fine motor control are facilitated by 23 associated muscles grouped by function.

Purpose of the Study:

• To elucidate the unique functional anatomy of the elbow joint complex.
• To enhance clinician understanding of elbow joint biomechanics.
• To improve knowledge regarding clinical examination and rehabilitation strategies for the elbow.

Main Methods:

• This is a review article.
• It synthesizes current knowledge on elbow joint anatomy and biomechanics.
• It focuses on clinical relevance for healthcare professionals.

Main Results:

• The elbow's unique anatomical configuration offers significant static stabilization.
• Numerous muscles provide dynamic stability and enable complex hand movements.
• A comprehensive understanding of these elements is crucial for clinical practice.

Conclusions:

• The elbow joint's intricate anatomy, including its osseous components, ligaments, and musculature, is fundamental to its function.
• Clinicians benefit from a thorough grasp of elbow biomechanics for accurate diagnosis and treatment.
• Effective rehabilitation protocols are informed by detailed anatomical and biomechanical knowledge of the elbow complex.
