This study provides new morphometric data and detailed illustrations of the triangular fibrocartilage complex (TFCC) articular disc (AD). Understanding TFCC AD anatomy is crucial for complex wrist repairs and improving patient outcomes.
Area of Science:
- Orthopedic Surgery
- Anatomy
- Biomechanical Engineering
Background:
- Advances in arthroscopy and MRI enable complex wrist repairs.
- The triangular fibrocartilage complex (TFCC) is vital for wrist stability.
- A detailed understanding of TFCC articular disc (AD) morphometry is needed.
Purpose of the Study:
- To reappraise the morphometry of the TFCC articular disc (AD).
- To emphasize the relationship between the AD and surrounding wrist tissues.
- To provide novel anatomical illustrations for educational and clinical use.
Main Methods:
- Dissection and precise measurement of 58 TFCC ADs from cadavers.
- Fabrication of 3D biofidelic plastic models of the ADs.
- Analysis of morphometric data, including length, width, and thickness.
Main Results:
- Mean AD length: 18.09 mm (left), 18.63 mm (right).
- Mean AD width: 9.60 mm (left), 9.93 mm (right).
- Significant morphometric differences found between male and female ADs (p < 0.05).
Conclusions:
- The study provides valuable morphometric data of the TFCC AD.
- Novel anatomical illustrations clarify TFCC structures and complex anatomy.
- Enhanced understanding benefits both educational and clinical applications in wrist surgery.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
