Radial Head Dislocation is uncommon. It most commonly presents as a partial dislocation or subluxation, also known as nursemaid’s elbow, seen in children. Complete radial head dislocation, although rare, is most commonly associated with high force injuries of the arm, and therefore are often associated with a forearm fracture or dislocation. A thorough history, physical

What Is Elbow Trauma? /Elbow Trauma is a common entity in the acute care setting.  In general, these injuries encompass a vast array of injury patterns from mild soft tissue injuries and contusions to complex osseoligamentous injury patterns and terrible triad injuries.  In the adult patient, most of these acute injuries occur secondary to high

Elbow Anterior Dislocations are rare due to the high force and position of the elbow necessary to cause this injury. Anterior elbow dislocations like all elbow dislocations occur after a traumatic event.  Patients will typically have a history of some mechanism, causing them to fall onto their outstretched arm or more severe trauma to the

Elbow Posterior Dislocation/A Posterior Elbow Dislocation often occurs when a person falls on an outstretched hand, posteriorly directed force at the elbow joint causes dislocation at the ulnohumeral and radiocapitellar articulations. Valgus force may induce the commonly seen posterolateral elbow dislocation.  [rx][rx][rx] Anterior elbow dislocations occur when the elbow is flexed, and there is a

Supinator is a spiral muscle contained in the posterior compartment of the forearm, along with brachioradialis, and the superficial and deep forearm extensors. Supinator muscle curls around the proximal part of the radius, connecting it with the ulna. In doing so, the muscle crosses the sagittal axis of the forearm. This interesting anatomy enables the supinator muscle to rotate the radius

Hand Abductor Pollicis Longus Muscle (APL) is the tendon of the first extensor compartment of the wrist. It helps in movement and stabilization of the thumb. Multiple tendinous insertions of APL has been reported by many authors.[rx] The anatomical variation may remain asymptomatic or may present with painful conditions like de Quervain tenosynovitis (DQT).[rx,rx] The

Nursemaid’s elbow, or “radial head subluxation” is a common injury in young children in which the radial head slips under the annular ligament resulting in pain and inability to supinate the forearm. Diagnosis is usually based on clinical exam and history, and reduction can typically be easily performed in the clinical setting.[rx][rx][rx][rx] Nursemaid’s elbow is

Radial Tunnel Syndrome refers to a rare compressive neuropathy of the posterior interosseous nerve (PIN) as it passes through the radial tunnel resulting in pain without motor or sensory dysfunction.[rx] This pain-only phenomenon is contrasted with PIN compression syndrome, which describes a more severe PIN compressive neuropathy, ultimately causing injury to the large myelin fibers of

Extensor Pollicis Longus Muscle is part of the deep extensors of the forearm together with extensor pollicis brevis, abductor pollicis longus, extensor indicis and supinator muscles. It is located on the posterior aspect of the forearm, extending from the middle third of the ulna, and adjacent interosseous membrane, to the distal phalanx of the thumb. Extensor pollicis longus muscle (EPL) is a skeletal muscle located dorsally on the forearm.

What Is Flexor Carpi Ulnaris Muscle/Flexor Carpi Ulnaris Muscle is a superficial flexor muscle of the forearm that flexes and adducts the hand. It is the most powerful wrist flexor. Flexor carpi ulnaris originates from 2 separate heads connected by a tendinous arch. The humeral head arises from a flexor tendon origin on the medial
