Summary
Glenohumeral joint instability requires clear classification for effective treatment. The new FEDS system offers a reliable method for categorizing instability, improving research consistency.
Area of Science:
- Orthopedics
- Sports Medicine
- Biomechanics
Background:
- Glenohumeral joint instability is a prevalent condition.
- Current definitions and classifications lack clarity, hindering research.
- Standardized classification is crucial for comparing and combining treatment studies.
Purpose of the Study:
- To review historical challenges in defining and classifying glenohumeral joint instability.
- To introduce the Functional, Etiologic, and Dimensional Stability (FEDS) system.
- To establish a clear and consistent classification for shoulder instability.
Main Methods:
- Literature review of historical instability classification systems.
- Development and validation of the FEDS system.
- Assessment of content validity, interobserver, and intraobserver agreement for the FEDS system.
Main Results:
- Historical classification methods present significant limitations.
- The FEDS system was developed with content validity.
- The FEDS system demonstrated high interobserver and intraobserver agreement.
Conclusions:
- A clear and validated classification system is essential for advancing glenohumeral joint instability research.
- The FEDS system provides a reliable framework for classifying shoulder instability.
- Implementing the FEDS system can improve the quality and comparability of clinical studies on shoulder instability.

01:09Functional Classification of Joints
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.

01:20Structural Classification of Joints
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.

01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:18Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.

01:26Classification of Systems-I
Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

01:31Classification of Systems-II
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,
