Dislocation, isolated and with associated injuries are often seen between 10 and 15 years of age 2. They are therefore useful only to exclude other injuries. Elbow Dislocation and Reduction ... Irreducible elbow dislocations may require operative management An elbow that has been unreduced for 7 or more days will likely require open reduction with an orthopedic surgeon. A collar and cuff are applied to support the plaster slab. The history is crucial, and familiarity with the typical mechanism is the most important element of diagnosis. Elbow dislocations are common and account for 10-25% of all elbow injuries in the adult population 1. The child regained satisfactory range-of-motion of the elbow with complete bony union within 3 months. Although elbow dislocations are much less common than fractures,3 it is important to make a prompt diagnosis since in the majority of patients this will enable closed reduction and result in a rapid return of normal function and appearance of the elbow. Radial head subluxations are discussed with a focus on current evidence for imaging, reduction techniques, and follow-up. Developed by The Royal Children's Hospital Emergency department. If my child has had a pulled elbow once, is he more likely to have it again because his ligament has stretched? Figure 13.6 (A) AP and (B) lateral radiographs of the left elbow of a 7-year-old girl showing a typical posterolateral dislocation of the elbow, which was reduced in the emergency department under sedation. The mechanism is thought to begin with the elbow in either the semi-flexed or hyperextended position. The majority of elbow dislocations are managed by closed reduction. Early mobilization of simple dislocations after closed reduction is associated with low risk of redislocation. It is estimated to occur between 3% to 6% of all paediatric elbow injuries 1–4. These are the brachialis and biceps anteriorly and the triceps posteriorly. However, it is now widely believed that subluxation results when the pronated, extended forearm of an infant has forcible traction applied through the longitudinal axis. They are the most common dislocation in children 4. In most cases, children with a pulled elbow will cry immediately after the sudden pull, and not use the injured arm at all. Is this dangerous? Approximately 65% of all fractures in children are to the upper limb, with the vast majority the result of indirect forces, following a fall on the outstretched hand (Fig. Adequate analgesia and anaesthesia are always essential to permit a safe and effective reduction of the elbow. Pulled elbow has a peak incidence at age 2–4 years. Additional indications are the treatment of associated fractures, existing open injury or the investigation of neurovascular compromise. Arterial damage to the main brachial trunk is rare.16,17 However, complete rupture, an intimal tear or simple kinking into the elbow joint can occur because of the tethering effect of the collaterals and surrounding soft tissue restraints. After plaster slab immobilization for 3 weeks, many children find the collar and cuff helpful for part-time use for about 1 week, until they regain confidence and a functional range of motion. However, it is now widely believed that subluxation results when the. The typical scenario is a parent suddenly pulling their child by the arm. Your child’s doctor will treat nursemaid elbow through a process called reduction. Elbow dislocations associated with a medial epicondyle fractureand ulnar nerve palsyare uncommon injuries. 13.6A, B). A pulled elbow is a common injury among children under the age of five. To donate, visit www.rchfoundation.org.au. predominantly affects patients between age 10-20 years old; Pathophysiology . 50 Flemington Road Parkville Victoria 3052 Australia, Site Map | Copyright | Terms and Conditions, A great children's hospital, leading the way. (C) The forearm is flexed (4) to maintain the reduction. (A) AP and (B) lateral radiographs of the left elbow of a girl involved in a motor vehicle accident, demonstrating multi-trauma in a single arm: a fracture of the distal humerus and a Bado type 1 Monteggia fracture–dislocation of the forearm. To prevent a pulled elbow, make sure you don't pick your child up by the lower arms or wrists – lift them up using their armpits instead. Examination may reveal tenderness over the radial head and annular ligament. Regional anesthesia may be used (eg, axillary nerve block) but has the disadvantage of limiting post-reduction neurologic examination. Indications for open reduction include failed closed reduction. Although anterior transolecranon dislocation of the elbow is not uncommon in adults, it is rarely seen in children. It involves gently moving the bone and ligament back into place. Dislocated elbow toddler / child. The principle of reduction is to counteract the muscle forces that are maintaining the dislocation. Given that the injury is a minor subluxation of a largely cartilaginous radial head, plain radiographs are expected to show no abnormality. This may occur due to interposed tissue, of which incarceration of the medial epicondyle within the joint is by far the most common. In this chapter we will discuss the management of pulled elbow, elbow dislocations and the Monteggia fracture–dislocation of the radial head. The partial dislocation will be reduced (manipulated back into place) by a nurse or doctor. Hypersupination is more useful and is often the critical step to unlock the radial head from behind the distal humerus.18. Limited published recommendations for the management of these lesions in children are available. The common causes of more severe stiffness are delayed diagnosis, immobilization beyond 3 weeks, and vigorous and early physiotherapy, particularly if this involves passive stretching and missed incarceration of the medial epicondyle necessitating delayed open reduction. Reduction is obtained by gently supinating the child’s forearm with one hand and applying gentle pressure over the radial head with the other. most common dislocated joint in children; account for 10-25% of injuries to the elbow ; posterolateral is the most common type of dislocation (80%) demographics . It usually happens when you pull children by their hands. A pulled elbow will not cause any long-term damage to your child if treated promptly and appropriately. If your child is not moving their arm fully by the next day, take them back to the doctor so that their arm can be evaluated again. This may occur due to interposed tissue, of which incarceration of the medial epicondyle within the joint is by far the most common. The diagnosis of a lateral condyle fracture can be challenging. Once a pulled elbow has been treated, your child should be able to return to normal activities. Approximately 65% of all fractures in children are to the upper limb, with the vast majority the result of indirect forces, following a fall on the outstretched hand (Fig. An elbow dislocation is a serious injury that needs medical care. Repeat radiographs must be undertaken to confirm the reduction and a repeat neurovascular examination performed after the child has fully recovered from sedation or anaesthesia (Fig. This procedure is painful and distressing, but it only lasts a short moment and is over when the radial bone pops back into place. Exercises are the mainstay of treatment after reduction and/or surgery for elbow dislocations and/or fracture-dislocations. Closed reduction is successful in more than 90% of isolated posterior dislocations. A strong, stretchy band called a ligament normally holds the radius bone in place, but after a fall or a sudden pull, the ligament can be overstretched and the bone partially slips out from underneath the ligament. Indeed, if not free to do so, these osseous landmarks are at risk of fracture. The stability of reduction should also be confirmed and the position maintained by a posterior plaster slab, extending from below the shoulder to the metacarpophalangeal joints. In addition, the coronoid process is also at risk of fracturing. Inset (right to left): the annular ligament may be stretched or torn, and once traction is discontinued may subluxate into the radiocapitellar joint. Isolated dislocation of the radial head is uncommon. Disruption of the posterior capsule may also occur and contribute to the risk of recurrent dislocation.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 (Fig. Your child will be observed for a short while to check that they are using their arm without any problems or pain. In addition, the coronoid process is also at risk of fracturing. The principle of reduction is to counteract the muscle forces that are maintaining the dislocation. A typical history and examination obviates the need for any investigations. 13.4). 13.2). This is done while the elbow is being flexed, which helps maintain the reduction (Fig. Reduction is first assessed clinically by the correction of the fixed deformity, restoration of range of motion and reformation of the normal posterior bony landmarks. Reduction of the dislocated elbow is the major treatment of a dislocated elbow. Traumatic dislocation of the elbow is rare in the paediatric population comprising only 3-6% of all childhood elbow injuries, but the most common large joint dislocation (Lieber et al., 2012). A pulled elbow is a result of the lower arm (radius bone) becoming partially dislocated (slipping out) of its normal position at the elbow joint. Complete arterial rupture is more likely in open injuries. If a fracture has been identified or is suspected, access to fluoroscopy will normally dictate transfer to the operating theatre. Figure 13.1 Typical mechanism of a child falling on an outstretched hand, which can result in various injuries to the upper limb. Their arm may simply hang by their side. Pulled elbow occurs in toddlers and children aged 1–6 years, with a peak incidence at age 2–4 years. Kids Health Info is supported by The Royal Children’s Hospital Foundation. Patients with a dislocated elbow usually experience sudden severe pain at the time of injury. The principle of reduction is to counteract the muscle forces that are maintaining the dislocation. Falls on the outstretched hand are common in childhood and occur in some toddlers on a daily basis. Some children are more likely than others to get a pulled elbow. It is usually the result of a fall onto an outstretched hand, often with a large amount of force involved. Lateral Condyle fractures (3) . Closed reduction of a posterior dislocation of the elbow in children is effective in more than 90% of cases. If the child is still unable to move his/her hand normally, the doctor will repeat the reduction. Open reduction is indicated for all displaced fractures and those demonstrating joint instability. The most common vascular injury is a compartment syndrome resulting from swelling and secondary compromise to the brachial artery and collateral circulation. Longitudinal traction on a pronated forearm is the typical mechanism for subluxation of the radial head, commonly termed ‘pulled elbow’ or ‘nursemaid’s elbow’. When the injury occurs: The child usually begins crying right away and refuses to use the arm because of elbow pain. Flexion at the elbow may also be required. Much less common are posteromedial, medial, lateral or anterior dislocations. Lateral radiographs confirm a posterior dislocation of the elbow (Fig. Median nerve entrapment may occur during reduction, as originally described by Hallet.15. A loss of between 5° and 10° of elbow extension is quite common but the majority of children and parents will be unaware of this deficit.18 However, children and parents should always be advised about this risk when consent is being taken for reduction of the dislocation. My child has had a pulled elbow before, and I know how toput the arm back into place. Tearing of the brachialis may expose the median nerve and brachial artery, which are then stretched directly over the trochlea. Teach others who care for your child, such as grandparents and child care workers, the correct way to pick up your child. This will help with the pain and will reduce some of the swelling. Closed reduction is successful in more than 90% of isolated posterior dislocations.19. Once diagnosed, the first step in treatment is to advise the child and the family that there will be a brief period of pain, followed almost immediately by relief and usage of the affected limb. If you think your child has a pulled elbow, you should seek immediate medical treatment from a GP or at a hospital emergency department. These are the brachialis and biceps anteriorly and the triceps posteriorly. Information contained in the handouts is updated regularly and therefore you should always check you are referring to the most recent version of the handout. The longer the elbow has been out of place, the more painful and difficult it is to put back into place, and the longer it takes to fully recover. A study of 1579 elbow injuries in skeletally immature individuals from Gothenberg, Sweden, found only 45 dislocations, giving a prevalence of only 3%. It is also sometimes called nursemaid’s elbow.

The examiner gently supinates the child’s forearm with one hand and applies gentle pressure over the radial head with the other. Early closed manipulation in the emergency department, without sedation, is the preferred treatment. 13.3). (A) AP and (B) lateral radiographs of the left elbow of a 7-year-old girl showing a typical posterolateral dislocation of the elbow, which was reduced in the emergency department under sedation. When it remains intact, the most common finding is a posterolaterally displaced radius and ulna in relation to the distal humerus. Given that more than 50% of elbow dislocations in children have associated fractures, the radiographs must be carefully examined for bony injuries (medial epicondyle, radial neck and coronoid).19 Less common fractures include lateral condyle, lateral epicondyle, medial condyle and olecranon. Arterial damage to the main brachial trunk is rare. Following the reduction, the child gets immediate relief from the elbow pain. When this valgus force is applied to either the hyperextended or semi-flexed elbow, the medial collateral ligament is torn or the medial epicondyle and common flexor origin are avulsed. If an elbow dislocation is associated with a fracture (fracture-dislocation), it is called "complex." The injury is extremely common and, because the majority of pulled elbows are treated in emergency departments or the offices of paediatricians or GPs; the exact incidence is not known. A doctor can put your child's elbow back in place. A transient synovitis may develop in patients with delayed presentation and in this circumstance a return of normal function of the arm can take up to 2 days. The authors of these consumer health information handouts have made a considerable effort to ensure the information is accurate, up to date and easy to understand. Many children, however, find the collar and cuff helpful for about 1 week after removal of the plaster slab until confidence is regained and a functional range of motion obtained. We acknowledge the input of RCH consumers and carers. 13.1). Leave the room to allow the child time to start using the arm. Primary ligament repair is not an appropriate indication as studies have shown that the outcome is inferior to closed treatment.21,22. Accurate diagnosis in the majority of elbow injuries can be made by a combination of knowing what to look for at specific ages, a good history and good-quality AP and lateral radiographs. First, traction longitudinally down the arm and supination of the forearm aids unlocking of the proximal radius and ulna. You will be advised if this is necessary. The medial epicondyle fracturewas missed initially … This relationship is maintained in supracondylar fractures, but lost in elbow dislocations (the apex normally moving posterolaterally). This can cause pain from the elbow to the hand. The diagnostic calendar: physeal injuries to the distal humerus occur at 0–6 years, pulled elbow at 2–4 years, supracondylar fracture of the distal humerus at 5–10 years and elbow dislocations at 12–14 years. Less common fractures occur to the coronoid and medial condyle. Following 4 weeks of immobilization, physiotherapy was started. Divergent dislocations and translocation dislocations are even rarer and can only occur in association with disruption of the PRUJ. Recurrent episodes occur in 5–39% of children until the annular ligament becomes stronger and stiffer. Your doctor probably put a splint on your child's elbow. Indeed, if not free to do so, these osseous landmarks are at risk of fracture. The dislocated elbow is clearly visible from outside. 1 In the present case, an avulsed fragment of the LCL attachment caused recurrent dislocation. Elbow dislocations, although less common than radial head subluxations, are also addressed, highlighting imaging, reduction, immobilization, and follow-up recommendations. We present the case of an 11-year-old girl with an elbow dislocationtreated by closed manual reduction. After 3 weeks, the plaster slab is removed and the child is allowed to freely mobilize the elbow. This allows the majority of uncomplicated, isolated dislocations to be reduced quickly and safely in the emergency department, provided that the procedure is undertaken by experienced staff.
