Joint Management.
Joints are mainly classified structurally and functionally.
Structural classification is determined by how the bones connect to each other,
while functional classification is determined by the degree of movement between
the articulating bones. In practice, there is significant overlap between the
two types of classifications.
Terms ending in the suffix -sis are singular and refer to just one joint, while
-ses is the suffix for pluralization.
Structural classification
Structural classification names and divides joints according to how the bones
are connected to each other. There are three structural classifications of
joints:
fibrous joint - joined by fibrous connective tissue
cartilaginous joint - joined by cartilage
synovial joint - not directly joined
Functional classification
Joints can also be classified functionally, by the degree of mobility they
allow:
synarthrosis - permits little or no mobility. Most synarthrosis joints are
fibrous joints (eg. The Skull).
amphiarthrosis - permits slight mobility. Most amphiarthrosis joints are
cartilaginous joints (eg. Vertebrae).
diarthrosis - permits a variety of movements. All diarthrosis joints are
synovial joints (eg. Shoulder, Hip, Elbow, Knee etc), and the terms "diarthrosis"
and "synovial joint" are considered equivalent by Terminologia Anatomica.
Biomechanical classification
Joints can also be classified based on their anatomy or on their biomechanical
properties. According to the anatomic classification, joints are subdivided into
simple and compound, depending on the number of bones involved, and into complex
and combination joints:
Simple Joint: 2 articulation surfaces (eg. shoulder joint, hip joint)
Compound Joint: 3 or more articulation surfaces (eg. radiocarpal joint)
Complex Joint: 2 or more articulation surfaces and an articular disc or meniscus
(eg. knee joint)
Anatomical
The joints may be classified anatomically into the following groups:
Articulations of hand
Elbow joints
Wrist joints
Axillary articulations
Sternoclavicular joints
Vertebral articulations
Temporomandibular joints
Sacroiliac joints
Hip joints
Knee joints
Articulations of foot
The better We
balance joint function the better the joint movability and articulation.
Therefore the better the Quality of Life.
