Symptom of a Dislocated Elbow Elbow Pain. It is important to look for associated ligamentous and musculotendinous injuries in this pattern. 5 public playlist includes this case. 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. Regional anesthesia may be used (eg, axillary nerve block) but has the disadvantage of limiting post-reduction neurologic examination. Elbow dislocations can be either simple or complex. Medial oblique compression fracture of the coronoid process of the ulna. 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). Elbow dislocation; Radial head fracture; Coronoid fracture; Clinical Features. Simple elbow dislocations are usually treated non-surgically. 1 However, some authors have reported good clinical outcomes of early active motion. Anterior dislocations occur much less frequently as a result of direct trauma to the flexed elbow. Elbow dislocations typically occur when a person falls onto an outstretched hand. 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 . Higher energy elbow dislocations are often associated with fractures of various parts of the elbow. 1 Elbow instability is typically described as being either ‘perched’ or ‘complete’. Examination reveals a loss of the triangular orientation between the medial and lateral epicondyles of the humerus and the olecranon process of the ulna . Elbow Dislocation Rehabilitation Protocol Elbow Dislocation The Elbow Joint is the most complex joint in the body. The joint was successfully reduced in the emergency department. Anterior elbow dislocations are held in extension, and the upper extremity appears elongated. “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. 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. An anterior elbow dislocation is relatively uncommon compared to posterior dislocation and is mostly associated with a transolecranon fracture dislocation. Clinical features include pain and swelling of the joint and an inability to flex/extend the elbow . Elbow pain is most often the result of tendinitis, which can affect the inner or outer elbow. There are many nerves that exist around the elbow, and whose function can be compromised by an elbow dislocation. Posterior Dislocation of the Elbow with Fractures of the Radial Head and Coronoid. Anterior dislocations of the elbow among children were often associated with fractures around the elbow, and some cases included neurovascular injury[6,7]. Elbow held in 45 degree of flexion; Olecranon is prominent posteriorly; Anterior dislocation. The elbow is the second most commonly dislocated large joint. With both injuries, the elbow is held semiflexed and swelling may be considerable. It is important to look for associated ligamentous and musculotendinous injuries in this pattern. Posterior elbow dislocations often present with an upper extremity that is flexed and appears shortened. Ligamentous elbow dislocation . Anterior elbow dislocation without periarticular fracture (simple dislocation) is an extremely rare injury and is usually caused by distraction or torsional forces. Swelling initially is usually less with a dislocation than with a type III supracondylar humeral fracture. - From Hippocrates to the Eskimo - a history of techniques used to reduce anterior dislocation of the shoulder. Terrible Triad Injuries of the Elbow: Does the Coronoid Always Need to Be Fixed? Posterior elbow dislocations often present with an upper extremity that is flexed and appears shortened. Of all elbow dislocations, 10-50% are sports related. The functionality of the elbow joint should be assessed by observing a range of movements. Elbow Dislocation Overview. Posterior elbow dislocation: Initial position with shoulder and elbow flexed to 90°C. The vast majority of dislocations are posterior. This injury is frequently confused with anterior Monteggia lesions by virtue of the readily apparent radiocapitellar dislocation. The functionality of the elbow joint should be assessed by observing a range of motion. Transverse Coronoid Fracture: When Does It Have to Be Fixed? The mechanism of injury includes a combination of axial loading, supination and, valgus (forearm moving away from midline) forces. Posterior elbow dislocations must be differentiated from extension-type supracondylar fractures of the distal humerus. 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. However, when a patient presents after a trauma with elbow pain, there are other diagnoses that need to be considered. Usually, there is a turning motion in this force. 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 . Open wounds would suggest a complex dislocation. Complex instability denotes the presence of a fracture associated with dislocation. A chronic dislocation is defined as a case in which the diagnosis was missed for several days to weeks after initial dislocation 2. The rate of elbow dislocation is 6-13 cases per 100,000 people, and this injury occurs more frequently in males than in females. Complex elbow dislocations have an associated fracture, while simple elbow dislocations do not. Most anterior dislocations have been manually reduced by the patient or by the surgeon in the emergency department. Anterior elbow dislocation without periarticular fracture (simple dislocation) is an extremely rare injury and is usually caused by distraction or torsional forces. Elbow dislocations can also happen in car accidents when the passengers reach forward to brace for impact. However, anterior elbow dislocations are a rare injury in both adults and children. 90% of elbow dislocations are posterior dislocations, most of which are simple posterior dislocations that follow a predictable sequence of soft tissue disruptions that eventually lead to a frank dislocation as described by O’Driscoll [1]. In order for it to recover to its best function consistent rehabilitation is essential in order to obtain the optimal outcome after injury. Elbow dislocations may occur in several directions: (1) posterior (the proximal forearm dislocates behind the distal humerus), (2) anterior, and (3) much more rarely, medial or divergent (the distal humerus gets interposed between proximal radius and ulna). A complete dislocation generally occurs in a posterior and lateral direction. Closed reduction was attempted in this case, but it … It is important that this be carefully carried out under the supervision of a therapist. They may be caused by strength imbalance of the rotator cuff muscles. Complex proximal ulna fractures (e. g. Monteggia-like injuries) are frequently associated with persisting disability. 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. On a basic level, the elbow is comprised of the articulation between the distal humerus with the proximal radius and ulna. Disruption of the posterior capsule may also occur and contribute to the risk of recurrent dislocation. Swelling may be severe; Displaced equilateral triangle of olecranon and epicondyles (undisturbed in supracondylar fracture) Posterior dislocation. 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. 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. This can drive and rotate the elbow out of its socket. E-Stim and ice PRN for edema and pain Exercises: With the splint on, full active flexion and extension to the extension block. This case demonstrates typical appearances of a simple posterior elbow dislocation. … Elbow dislocations are generally more common in women and in the non-dominant arm. More than 90% of elbow dislocations are posterior dislocations. Anterior elbow dislocations are held in extension, and the upper extremity appears elongated. Elbow dislocations frequently occur due to trauma such as falls from heights or motor vehicle collisions. These higher energy injuries are defined as “complex” elbow dislocations. Coronoid fractures are often the result of posterior elbow dislocation, which needs to be kept in mind during rehabilitation of these injuries. 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. Anterior elbow dislocations tend to be a clinical diagnosis and are confirmed by radiographic images. Posterior dislocations are uncommon, and are typically due to the muscle contraction from electric shock or seizure. 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. 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. Posterior splint immobilization for three weeks is frequently preferred. Associated fractures often occur with elbow dislocations. 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. When the hand hits the ground, the force is sent to the elbow. FA pronation/supination casos; MSK - Clinical Conditions - Elbow; Anterior shoulder dislocation; Upper limb fractures (iOS pack) Rotorua Teaching - Elbow Radiographs ; Related Radiopaedia articles. With a ‘perched’ injury the elbow is subluxed, but the coronoid process is impinged on the trochlea. 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]. An elbow dislocation occurs when the bones of the elbow (ulna, radius, and humerus) come out of their normal positions. Elbow dislocations are described by the direction of the proximal ulna relative to the humerus. 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. Specific attention should be paid to looking for open wounds which would suggest a complex dislocation. The elbow joint is the second most commonly dislocated joint in adults, after the shoulder. 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. 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. Although anterior transolecranon fracture dislocations are well recognized in adults 13, they have been reported in only a small series of children 8.
