What is a Annular Ligament Injury? An annular ligament injury involves damage to the strong band of tissue that encircles the head of the radius, securing it to the ulna and stabilizing the elbow joint. It often results from trauma, such as a fall or sudden pulling motion, commonly seen in young children (referred to…
Introduction The annular ligament is a strong, circular band of fibrous tissue that wraps around the head of the radius, securing it to the ulna at the proximal radioulnar joint. It allows the radius to rotate smoothly during forearm movements like pronation and supination while maintaining joint stability. The annular ligament is made of thick…
Introduction The radial collateral ligament (RCL) is a strong, fibrous band located on the lateral side of the elbow joint. It connects the lateral epicondyle of the humerus to the annular ligament, providing stability to the outer elbow and supporting the joint during activities involving arm movement. It primarily resists excessive varus forces, preventing the…
What is a Greenstick Fracture? A greenstick fracture is a type of bone fracture commonly seen in children, where the bone bends and partially breaks, similar to how a green twig snaps. It typically occurs due to a fall or direct trauma and is often seen in the arms. Treatment usually involves immobilization with a…
Introduction The Posterior Cruciate Ligament (PCL) is one of the four major ligaments in the knee, located at the back of the joint. It connects the femur (thigh bone) to the tibia (shin bone) and primarily functions to prevent the tibia from moving too far backward. The PCL provides stability to the knee, especially during…
Introduction The Anterior Cruciate Ligament (ACL) is a key ligament located in the knee joint, connecting the femur (thigh bone) to the tibia (shin bone). It provides stability by preventing excessive forward movement of the tibia and controlling rotational forces. ACL injuries, often caused by sudden stops, changes in direction, or direct impact, are common…
A High Ankle Sprain: What is it? A high ankle sprain is caused by tearing or injuring the high ankle ligaments that connect the tibia and fibula. A sprain occurs when a ligament is stretched beyond its normal limits or ruptured. Sprains come in three levels of severity: These ligaments are called syndesmosis, even though…
Introduction The Medial Collateral Ligament (MCL) is a band of tissue located on the inner side of the knee, connecting the femur (thigh bone) to the tibia (shin bone). It provides stability by preventing excessive inward movement of the knee joint. MCL injuries can range from minor sprains to full tears and can be caused…
Crepitus/Cracking Joints: What is it? Crepitus refers to a crackling, popping, or grating sound or sensation that can occur in joints or tissues. It often happens during movement and may be caused by gas bubbles in the joint, cartilage wear, or bone rubbing against bone. While it is generally harmless, persistent or painful crepitus may…
Introduction The ulnar collateral ligament (UCL) is a strong band of tissue located on the inner side of the elbow, connecting the humerus (upper arm bone) to the ulna (one of the forearm bones). It provides stability to the elbow joint, particularly during activities involving throwing or overhead motions. UCL injuries are common in athletes,…
