The possible relationship between the palmaris longus and joint hypermobility
1Department of Plastic, Reconstructive and Aesthetic Surgery, Faculty of Medicine, Van Yuzuncu Yil University, Van, Türkiye. canseryilmazdemir@yyu.edu.tr.
Summary
This study found no association between the palmaris longus muscle and joint hypermobility. Further research is needed to explore potential links in specific populations.
Area of Science:
- Anatomy and Musculoskeletal Research
- Orthopedics and Sports Medicine
Background:
- The palmaris longus (PL) muscle plays a role in wrist function and is a common graft source.
- Joint hypermobility (JH) is linked to various health issues and complaints.
- An evolutionary hypothesis suggests a potential association between PL presence and JH.
Purpose of the Study:
- To investigate the hypothesis that the palmaris longus muscle is associated with joint hypermobility.
- To compare the prevalence and severity of joint hypermobility in individuals with and without the palmaris longus.
Main Methods:
- A study involving 200 participants (50% female, 50% male) was conducted between June and October 2023.
- The Schaeffer's test assessed palmaris longus presence, while the Beighton score evaluated joint hypermobility.
- Participants were grouped based on palmaris longus presence, with demographic and Beighton scores compared, including gender-specific subgroup analyses.
Main Results:
- No statistically significant differences were observed in age, gender, weight, height, work status, Beighton scores, or joint hypermobility between individuals with and without the palmaris longus.
- These findings remained consistent across analyses of the combined group, females only, and males only.
Conclusions:
- This study found no evidence of a relationship between the palmaris longus muscle and joint hypermobility.
- This is the inaugural study to examine this specific association, acknowledging inherent limitations.

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

01:07Development of the Limb Synovial Joints
1.4K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

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.

01:10Ankle Joint
1.5K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:16Structural Joints: Synovial Joints
3.5K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

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.
