The elbow is the second most commonly dislocated large joint. With a ‘perched’ injury the elbow is subluxed, but the coronoid process is impinged on the trochlea. Posterior elbow dislocations often present with an upper extremity that is flexed and appears shortened. Examination reveals a loss of the triangular orientation between the medial and lateral epicondyles of the humerus and the olecranon process of the ulna . The radial nerve runs in the posterior compartment of the arm in the radial groove of the humerus and wraps laterally to its position near the elbow, where it is anterior to the lateral epicondyle. A complete dislocation generally occurs in a posterior and lateral direction. It is important to look for associated ligamentous and musculotendinous injuries in this pattern. This injury is frequently confused with anterior Monteggia lesions by virtue of the readily apparent radiocapitellar dislocation. Terrible Triad Injuries of the Elbow: Does the Coronoid Always Need to Be Fixed? Elbow dislocations can also happen in car accidents when the passengers reach forward to brace for impact. Anterior elbow dislocations tend to be a clinical diagnosis and are confirmed by radiographic images. Regional anesthesia may be used (eg, axillary nerve block) but has the disadvantage of limiting post-reduction neurologic examination. Higher energy elbow dislocations are often associated with fractures of various parts of the elbow. 5 public playlist includes this case. Elbow dislocations can be either simple or complex. It is important to look for associated ligamentous and musculotendinous injuries in this pattern. 14 The brachialis muscle, in its position between the anterior capsule and the more superficial neurovascular structures, is at risk during dislocation of the elbow but is particularly liable to be torn if hyperextension forces are applied in order to achieve reduction of the joint . They may be caused by strength imbalance of the rotator cuff muscles. However, anterior elbow dislocations are a rare injury in both adults and children. People with dislocated shoulders typically present holding their arm internally rotated and adducted, and exhibiting flattening of the anterior shoulder with a prominent coracoid process. Ligamentous elbow dislocation . Closed reduction has commonly been performed, except in cases involving soft-tissue interposition or buttonholing of the radial head through the capsule that have prevented it[8,9]. Symptom of a Dislocated Elbow Elbow Pain. Clinical features include pain and swelling of the joint and an inability to flex/extend the elbow . Management of Simple Elbow Dislocation Bradford O. Parsons David M. Lutton DEFINITION Simple elbow dislocation is a dislocation of the ulnohumeral joint without concomitant fracture. Elbow pain is most often the result of tendinitis, which can affect the inner or outer elbow. Posterior splint immobilization for three weeks is frequently preferred. Posterior elbow dislocations must be differentiated from extension-type supracondylar fractures of the distal humerus. Elbow dislocations are described by the direction of the proximal ulna relative to the humerus. Neurapraxia has been reported to occur in approximately 20% of elbow dislocations and usually involves the anterior interosseous branch of the median nerve and/or the ulnar nerve. Anterior elbow dislocation without periarticular fracture (simple dislocation) is an extremely rare injury and is usually caused by distraction or torsional forces. 1 Elbow instability is typically described as being either ‘perched’ or ‘complete’. FA pronation/supination On a basic level, the elbow is comprised of the articulation between the distal humerus with the proximal radius and ulna. Elbow Dislocation Overview. 3 Stability of the elbow to valgus stress, with the forearm pronated after reduction of the posterior dislocation indicated that early motion could be permitted because the anterior portion of the medial collateral ligament was intact. Simple elbow dislocations are usually treated non-surgically. Elbow dislocations frequently occur due to trauma such as falls from heights or motor vehicle collisions. When the hand hits the ground, the force is sent to the elbow. Transverse Coronoid Fracture: When Does It Have to Be Fixed? Elbow dislocations are generally more common in women and in the non-dominant arm. Elbow dislocation; Radial head fracture; Coronoid fracture; Clinical Features. Posterior elbow dislocations are painful; IV analgesia may be given prior to x-rays, and PSA—alone or combined with intra-articular anesthesia—is usually given for the procedure. With both injuries, the elbow is held semiflexed and swelling may be considerable. This case demonstrates typical appearances of a simple posterior elbow dislocation. Swelling initially is usually less with a dislocation than with a type III supracondylar humeral fracture. Anterior elbow dislocations are held in extension, and the upper extremity appears elongated. 1 However, some authors have reported good clinical outcomes of early active motion. Complex elbow dislocations have an associated fracture, while simple elbow dislocations do not. Anterior elbow dislocations are held in extension, and the upper extremity appears elongated. Disruption of the posterior capsule may also occur and contribute to the risk of recurrent dislocation. Anterior dislocations of the elbow among children were often associated with fractures around the elbow, and some cases included neurovascular injury[6,7]. The joint was successfully reduced in the emergency department. This can drive and rotate the elbow out of its socket. The vast majority of dislocations are posterior. Medial oblique compression fracture of the coronoid process of the ulna. The functionality of the elbow joint should be assessed by observing a range of movements. However, when a patient presents after a trauma with elbow pain, there are other diagnoses that need to be considered. The elbow is a synovial hinge joint and posterior dislocation of the ulna relative to the distal humerus is the most common type of dislocation, with the coronoid process of the ulna moving posteriorly away from the humeral trochlear. A number of injuries can present as elbow pain, such as a distal humerus fracture, fracture of the radial head, fracture of the olecranon, or purely ligamentous injuries. Posterior elbow dislocations often present with an upper extremity that is flexed and appears shortened. Complex instability denotes the presence of a fracture associated with dislocation. Posterior Dislocation of the Elbow with Fractures of the Radial Head and Coronoid. Closed reduction was attempted in this case, but it … - From Hippocrates to the Eskimo - a history of techniques used to reduce anterior dislocation of the shoulder. There are many nerves that exist around the elbow, and whose function can be compromised by an elbow dislocation. Elbow Dislocation Rehabilitation Protocol Elbow Dislocation The Elbow Joint is the most complex joint in the body. The rate of elbow dislocation is 6-13 cases per 100,000 people, and this injury occurs more frequently in males than in females. Although anterior transolecranon fracture dislocations are well recognized in adults 13, they have been reported in only a small series of children 8. E-Stim and ice PRN for edema and pain Exercises: With the splint on, full active flexion and extension to the extension block. The operator places both hands around the distal humerus such that the fingers rest on the anterior aspects of the medial and lateral supracondylar ridges of the distal humerus and the thumbs rest on the posterior aspect of the olecranon process. An elbow dislocation occurs when the bones of the elbow (ulna, radius, and humerus) come out of their normal positions. casos; MSK - Clinical Conditions - Elbow; Anterior shoulder dislocation; Upper limb fractures (iOS pack) Rotorua Teaching - Elbow Radiographs ; Related Radiopaedia articles. An elbow dislocation occurs when the bones of the forearm (the radius and ulna) move out of place compared with the bone of the upper arm (the humerus). Usually, there is a turning motion in this force. An anterior elbow dislocation is relatively uncommon compared to posterior dislocation and is mostly associated with a transolecranon fracture dislocation. Simple Elbow Dislocation • No associated fractures • Complete or near complete capuloligamentous injury • Extensive muscle injury • Nearly always stable after reduction • No advantage to surgery if stable • No more than 2 weeks immobilization . Coronoid fractures are often the result of posterior elbow dislocation, which needs to be kept in mind during rehabilitation of these injuries. Posterior (about 90% of all elbow dislocations) Anterior; Lateral; Partially displaced; In young children (ages less than about 4-5 years), the elbow dislocation is termed a radial head subluxation or nursemaid's elbow. Ulnar nerve palsy has been reported in 14% of adult elbow dislocations, and the incidence is much higher in paediatric elbow dislocations with an associated medial epicondyle fracture. Anterior elbow dislocation without periarticular fracture (simple dislocation) is an extremely rare injury and is usually caused by distraction or torsional forces. An elbow dislocation is not difficult to diagnose; the elbow deformity is readily evident and is associated with a marked pain, swelling, and tenderness of the elbow. A chronic dislocation is defined as a case in which the diagnosis was missed for several days to weeks after initial dislocation 2. “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. These higher energy injuries are defined as “complex” elbow dislocations. Anterior dislocations occur much less frequently as a result of direct trauma to the flexed elbow. Anterior elbow dislocations occur most often as a fracture-dislocation in which the distal humerus is driven through the olecranon, thereby causing a complex, comminuted fracture of the proximal ulna.
