Scapholunate Ligament Injury

What is a Scapholunate Ligament Injury? A scapholunate ligament injury involves damage to the ligament connecting the scaphoid and lunate bones in the wrist. This ligament plays a key role in stabilizing the carpal bones and maintaining proper wrist mechanics. Injury typically results from a fall on an outstretched hand or repetitive strain, leading to…

Perineal Nerve

Introduction The perineal nerve is a big terminal branch of the pudendal nerve that normally begins during its passage through the pudendal canal or shortly after it exits the canal. The pudendal nerve travels to the perineum before splitting into two terminal branches: the superficial perineal nerve (superficial perineal branch) and the deep perineal nerve….

Pronator Quadratus Muscle

Introduction The pronator quadratus is a quadrangular, thin, short, and flat muscle located in the anterior compartment of the forearm. It is a member of the deep group of forearm flexors, together with flexor digitorum profundus and pollicis longus. The superficial group of forearm flexors overlays these three muscles. The pronator quadratus connects the distal…

Ligamentum Flavum Injury

Introduction: The ligamentum flavum is a strong, elastic ligament that connects the laminae of adjacent vertebrae, playing a crucial role in maintaining spinal stability and posture. Injury to this ligament, often due to trauma, repetitive strain, or degenerative changes, can lead to thickening or hypertrophy, potentially compressing nearby nerves or the spinal cord. This may…

Anterior Longitudinal Ligament (ALL) Injury

What is an Anterior Longitudinal Ligament (ALL) Injury? The Anterior Longitudinal Ligament (ALL) runs along the front of the spine, providing stability and preventing excessive extension (backward bending). Injury to the ALL often occurs due to hyperextension trauma, such as whiplash from car accidents or sports injuries. Symptoms may include pain, stiffness, and limited spinal…

Anterior Talofibular Ligament (ATFL)

Introduction The Anterior Talofibular Ligament (ATFL) is a key ligament in the ankle, connecting the fibula to the talus. It is the most commonly injured ligament in ankle sprains, especially with inversion injuries. The ATFL helps stabilize the ankle by preventing excessive forward displacement of the talus. The anterior talofibular ligament, situated on the lateral…

Posterior Talofibular Ligament

Introduction The Posterior Talofibular Ligament (PTFL) is a strong ligament in the ankle that connects the talus to the fibula. It is the strongest of the lateral ankle ligaments and plays a crucial role in stabilizing the ankle, especially in preventing excessive posterior movement of the talus. Injuries to the PTFL are rare and usually…

Triangular Fibrocartilage Complex (TFCC) Injury

What is Triangular Fibrocartilage Complex Injury? The Triangular Fibrocartilage Complex (TFCC) injury involves damage to the cartilage and ligaments on the ulnar side of the wrist, which provide stability and cushioning. It commonly occurs due to falls on an outstretched hand, repetitive wrist motions, or degenerative wear. Symptoms include wrist pain, weakness, and clicking sensations,…

Calcaneofibular Ligament

Calcaneofibular Ligament

Introduction The calcaneofibular ligament (CFL) is a strong, fibrous band located on the lateral side of the ankle. It connects the fibula to the calcaneus (heel bone) and provides stability by preventing excessive inversion of the foot. It is commonly injured in ankle sprains, particularly in combination with the anterior talofibular ligament (ATFL). Like the…
