Summary
Loose ligaments are linked to temporomandibular joint (TMJ) disorders. This study of 701 patients found correlations between TMJ issues, pain, and ligament laxity, highlighting a key predisposing factor.
Area of Science:
- Orthopedics
- Rheumatology
- Dental Medicine
Background:
- Temporomandibular joint (TMJ) disorders are common, often associated with underlying structural factors.
- Ligamentous laxity is increasingly recognized as a potential contributor to joint instability and dysfunction.
Purpose of the Study:
- To investigate the correlation between loose ligaments and the prevalence of temporomandibular joint (TMJ) disorders.
- To analyze demographic and clinical factors associated with TMJ pain and dysfunction in relation to ligament laxity.
Main Methods:
- A cohort of 701 subjects with TMJ pain or dysfunction were evaluated.
- Standardized jaw examinations were performed.
- The Carter and Wilkinson test, modified by Beighton, was utilized to assess ligamentous laxity.
Main Results:
- A significant correlation was identified between loose ligaments and the presence of TMJ disorders.
- Associations were found among age, gender, TMJ disorder diagnosis, joint pain, muscle pain, and the degree of ligament laxity.
Conclusions:
- Ligamentous laxity is a significant predisposing factor for temporomandibular joint (TMJ) disorders.
- Clinical assessment of ligamentous laxity may aid in understanding and managing TMJ dysfunction.

01:03Structural Joints: Fibrous Joints
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:17Structural Joints: Cartilaginous Joints
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...

01:26Joints
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
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.
Fibrous Joints Are Immovable

01:26Loose Connective Tissue
Loose connective tissue is found between many organs. Its main function is to absorb shock and bind tissues together. It also allows water, salts, and various nutrients to diffuse into cells that are embedded in it or present in adjacent tissues.
Adipose Tissue
Adipose tissue consists primarily of fat storage cells called adipocytes and little extracellular matrix. A large number of capillaries present within adipose tissue allow rapid mobilization of lipid molecules. White adipose tissue is...

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

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.
