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: Cervicogenic headaches often stem from neck tension or poor posture. Effective exercises to relieve these headaches include neck stretches, chin tucks, upper trapezius stretches, and scapular retractions. These help reduce muscle tightness, improve posture, and relieve pressure on the cervical spine. Typical characteristics of this kind of headache include: Although it sometimes affects both…
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 intercostal nerves are a group of 11 pairs of nerves that originate from the thoracic spinal cord (T1 to T11). They run between the ribs, supplying the muscles of the chest wall and providing sensory information from the skin and pleura. The 12th pair, called the subcostal nerve, runs below the last rib….
Introduction The cervical plexus is a collection of cervical nerves created by the anterior (ventral) rami of spinal nerves C1-C4 (sometimes known as the first through fourth cervical nerves). The cervical plexus’ roots (limbs) are shown here. The 5th cervical nerve (the anterior ramus of spinal nerve C5) may also be regarded as a member…
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…
Knee Flexion Knee Flexion refers to the bending movement of the knee joint, where the angle between the thigh and the lower leg decreases. It involves muscles like the hamstrings, gastrocnemius, and popliteus. Knee flexion is essential for activities like walking, running, and squatting. Knee Flexion and Extension: What Is It? Basic motions at the…
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…
