Introduction Ulnar deviation is the movement of the hand toward the little finger (ulnar) side, facilitated by the flexor carpi ulnaris and extensor carpi ulnaris. These motions are essential for grip, wrist flexibility, and functional hand movements. Radial and ulnar deviation are wrist movements occurring in the frontal plane. Radial deviation is the movement of…
Introduction The medial pectoral nerve arises from the medial cord of the brachial plexus (C8-T1). It primarily innervates the pectoralis major (sternocostal head) and pectoralis minor muscles. Unlike the lateral pectoral nerve, it pierces the pectoralis minor before reaching the pectoralis major. This nerve plays a role in shoulder adduction, internal rotation, and scapular stabilization….
What is a Thoracic Outlet Syndrome? Thoracic Outlet Syndrome (TOS) is a condition caused by compression of nerves, arteries, or veins in the thoracic outlet—the space between the collarbone and first rib. It can lead to pain, numbness, tingling, and weakness in the arm and hand. Common causes include poor posture, repetitive movements, trauma, or…
Introduction Steroid injections, also known as corticosteroid injections, are anti-inflammatory drugs used to treat various conditions, including inflammatory bowel disease, sciatica, arthritis, and joint pain. A dose of medication is administered directly to a problem area in your body using a corticosteroid, also known as a steroid injection. Inflammation can be lessened with the use…

What is a Scaphoid Fracture? A scaphoid fracture is a break in the scaphoid bone, a small, boat-shaped bone in the wrist, located near the base of the thumb. The scaphoid is the most commonly fractured carpal bone, and it is more likely to occur in young children and the elderly than in the distal…
The patellofemoral joint is a unique and complex structure composed of static (bones and ligaments) and dynamic (the neuromuscular system) elements. The patella is shaped like a triangle, having an inferiorly oriented tip. The primary articulating surfaces of the patellofemoral joint are the trochlea and the distal articulating surface of the femur, with which it articulates superiorly. Introduction The patellar surface of the femur and the posterior surface of the patella articulate to produce…
Introduction The Anterior Interosseous Nerve (AIN) is a branch of the median nerve that arises in the forearm. It supplies the flexor pollicis longus (FPL), the lateral half of the flexor digitorum profundus (FDP) (to the index and middle fingers), and the pronator quadratus (PQ). It is purely a motor nerve, with no sensory function….
Introduction The long thoracic nerve arises from the C5-C7 nerve roots and innervates the serratus anterior muscle. It plays a crucial role in scapular stability, preventing winging of the shoulder blade. Injury to this nerve can result in scapular winging, weakness in shoulder protraction, and difficulty in overhead movements. The serratus anterior muscle, one of…
