If the reduction is concentric and the joint is stable, the elbow should be splinted in 90 degrees of flexion. The elbow joint is considered relatively stable; however, elbow dislocations are a fairly common occurrence. Posterior or posterolateral displacement of the ulna relative to the distal humerus is the most common simple dislocation with approximately 90% occurring this way (see image ). Elbow dislocations are the second most common joint dislocation, following shoulder dislocations. He advocated a varus stress onto the elbow joint so that its subluxation would open the lateral space to facilitate manipulation and head reduction toward its anatomic position. These injuries, are more difficult to treat, and often have poorer results than simple dislocation. A dislocated elbow is a condition characterized by damage and tearing of the connective tissue surrounding the elbow joint with subsequent displacement of the bones forming the joint so they are no longer situated next to each other. Most elbow dislocations are closed and are most frequently posterior (sometimes posterolateral or posteromedial) although anterior, medial, lateral and divergent dislocations are also infrequently encountered). Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Patients should be followed up in 3-5 days with repeat X-rays to check reduction. Pathophysiology. It requires adequate muscular relaxation and appropriate analgesia. Which of the following injuries could be appropriately managed with a long arm posterior splint for 8-12 days, followed by protected range of motion exercises? Posterior splint immobilization for three weeks is frequently preferred. Elbow dislocations are classified by direction of dislocation as posterior, lateral, anterior, or divergent and also as simple or complex, depending on whether fractures are also present. Valgus force may induce the commonly seen posterolateral elbow dislocation. most common dislocated joint in children. Associated radial head … Traction should be maintained with the arm in moderate flexion, using counter-traction with the fingers. In most instances, the semilunar notch of the ulna is dislocated posteriorly from the distal … The arm may enlocate at this stage with a characteristic and satisfying reduction ‘clunk’. This allows the ulna to “perch” on the distal humerus. These symptoms may, in particular, brought up by activities which place the elbow in its unstable position of external rotation of the forearm with valgus and axial loading, such as pushing up from a chair or doing push-ups. (OBQ13.161)
Most dislocated elbows are unstable to valgus stress (best tested in pronation to lock the lateral side).

Higher energy elbow dislocations are often associated with fractures of various parts of the elbow. A dislocated elbow occurs when the bones that make up the joint are forced out of alignment — typically when you land on an outstretched hand during a fall. Rarer injuries include lateral and anterior displacements of the forearm. Athletic injuries account for up to 50% of elbow dislocations. Complex elbow dislocation consists of both ligamentous and bony injuries. A dislocated elbow happens when the bones in the lower arm move out of place compared to the humerus. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. E-Stim and ice PRN for edema and pain Exercises: With the splint on, full active flexion and extension to the extension block. Elbow Dislocation Rehabilitation Protocol Elbow Dislocation The Elbow Joint is the most complex joint in the body. A partial dislocation is also called a subluxation. In order for it to recover to its best function consistent rehabilitation is essential in order to obtain the optimal outcome after injury. Posterior or posterolateral dislocations are most common.

FA pronation/supination Most patients can recall a traumatic event, frank elbow dislocationor fall in outstretched hands. These cookies will be stored in your browser only with your consent. Clinical evaluation should include median and ulna nerve function. When larger intra-articular fractures of the radial head, olecranon, or coronoid process occur with elbow dislocation, the injury is termed a complex dislocation. The risk of recurrent or chronic instability and posttraumatic arthrosis is increased significantly with complex dislocation. Posterior dislocations typically occur following a fall onto an extended arm, either with hyperextension or a posterolateral rotatory mechanism 1. Reduction may be achieved by correction of the medial or lateral displacement followed by strong traction on the forearm in the line of the limb. hyperextension, valgus stress, and supination; anterior dislocation. “Posterior Elbow Dislocation” Protocol Sequence Phase I: Days 3-5 Sling immobilization progressing to extension blocking (custom splint or articulated brace) locked at 30 degrees of extension. Rarer injuries include lateral and anterior displacements of the forearm. The elbow should be slowly extended and the angle at which tendency to redislocation occurs should be recorded. Elbow dislocations can be either simple or complex. This stability is provided by the osseous and articular components with the shape and contour of the ulnohumeral articular surface providing anterior-posterior stability, varus/valgus, and rotatory stability. Early mobilization of simple dislocations after closed reduction is associated with low risk of redislocation.

(Also known as Elbow Dislocation, Posterior Dislocation of the Elbow) What is a dislocated elbow? After a complete examination, AP and lateral X-Rays of the elbow should be examined to determine the direction of the dislocation and to identify any associated fractures. Posterior or posterolateral displacement of the ulna relative to the distal humerus is the most common simple dislocation with approximately 90% occurring this way (see image ). Further soft tissue or osseous injury results in dislocation 13 . Reduction can usually be carried out in the emergency department. Other structures that can be damaged include: medial and lateral collateral ligaments; medial and lateral condyles/epicondyles; transolecranon fractures and; posterior Monteggia fractures.

Damage to the brachial artery can be assessed by palpating for a radial pulse. If not, firm pressure is applied posteriorly to the olecranon to bring it distally and anteriorly around the humeral trochlea. Complex dislocations should have the same initial treatment- with clinical evaluation and reduction- as simple dislocations. Emergency physician MA (Oxon) MBChB (Edin) FACEM FFSEM with a passion for rugby; medical history; medical education; and informatics. Simple dislocations are described by the direction of the dislocated ulna. X-Rays should then be performed in two planes, AP and lateral to ensure the reduction is concentric. ation, thus causing radial head posterior displacement. Posterior elbow dislocation is a traumatic injury of the elbow, occurring when the radius and ulna are vigorously driven posterior to the humerus. When the ulnar bone slips out to the back of your elbow, the condition is known as a posterior elbow dislocation. To reduce dislocation: an assistant should stabilize the humerus in 30 degrees of flexion, supinated and apply countertraction provider applies traction to the supinated distal forearm following reduction, patients should be immobilized in a posterior splint with orthopedic follow-up in 1 week Causes are trauma usually due to falling with an outstretched arm. predominantly affects patients between age 10-20 years old. treatment is usually closed reduction followed by brief immobilization unless the medial epicondyle has an incarcerated fragment in the joint that is blocking reduction. Dislocation of the elbow is second in frequency to that of the shoulder. Elbow dislocations can be complete or partial, and usually occur after a trauma, such as a fall or accident. Posterior dislocations with associated fractures, also known as complex posterior dislocations, often require open reduction and internal fixation (ORIF). These higher energy injuries are defined as “complex” elbow dislocations. The capsuloligamentous components, which include the medial and lateral collateral ligaments and joint capsule, provide further stability by completing a structural ring about the elbow joint.
