Summary
Joint hypermobility is significantly more common in children with pulled elbows, affecting 73% of cases. This suggests a strong association between hypermobility and the frequent occurrence of pulled elbows in young children.
Area of Science:
- Pediatrics
- Orthopedics
- Genetics
Background:
- Pulled elbow injuries are common in young children.
- Joint hypermobility affects approximately 5% of the general population.
- The relationship between pulled elbow and joint hypermobility requires further investigation.
Purpose of the Study:
- To investigate the prevalence of joint hypermobility in children diagnosed with pulled elbows.
- To compare hypermobility rates in children with pulled elbows versus a control group.
- To explore the familial occurrence of hypermobility in relation to pulled elbow injuries.
Main Methods:
- A prospective study was conducted over two years.
- One hundred children diagnosed with pulled elbows and their parents were assessed for joint hypermobility.
- A control group of 30 children without pulled elbows was included for comparison.
Main Results:
- The prevalence of hypermobility in children with pulled elbows was 73%, significantly higher than in the control group (50%).
- Hypermobility was more pronounced in the elbows and knees of children with pulled elbows.
- Maternal hypermobility was reported in 48% of cases with pulled elbows, compared to 10% in the control group.
Conclusions:
- Joint hypermobility is strongly associated with an increased incidence of pulled elbows in children.
- While hypermobility is a significant risk factor, other anatomical and mechanical factors may also contribute to pulled elbow injuries.
- Further research is warranted to elucidate the multifactorial etiology of pulled elbows.

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
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...

01:10Ankle Joint
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...
01:07Development of the Limb Synovial Joints
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.

00:51Anatomical Movements
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...

01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
