The history is crucial, and familiarity with the typical mechanism is the most important element of diagnosis. Parents should be warned about this, and of the need to seek further medical attention if considerable improvement is not evident within the first 24 h. The success rate of manipulation is very high and all pulled elbows appear eventually to self-relocate, without any long-term sequelae.7 Delayed presentation may result in failed manipulation. Closed reduction is successful in more than 90% of isolated posterior dislocations. An isolated dislocation without fracture is "simple." Examination for associated fractures is essential even though it frequently proves difficult due to swelling and pain around the elbow. The examiner gently supinates the child’s forearm with one hand and applies gentle pressure over the radial head with the other. 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. Clinical differentiation should be made between an elbow dislocation and an extension-type supracondylar fracture of the humerus by examining for the normal equilateral triangular relationship between the humeral epicondyles and the tip of the olecranon. Divergent dislocations and translocation dislocations are even rarer and can only occur in association with disruption of the PRUJ. The principle of reduction is to counteract the muscle forces that are maintaining the dislocation. 13.4). predominantly affects patients between age 10-20 years old; Pathophysiology . Early closed manipulation in the emergency department, without sedation, is the preferred treatment. There’s a type of partial dislocation called nursemaid’s elbow, or pulled elbow, and it’s common in tots 4 and younger. Relocation is recognized by an audible or palpable snap, which may require elbow flexion in addition to supination. This is done while the elbow is being flexed, which helps maintain the reduction (Fig. Pulled elbow has a peak incidence at age 2–4 years. However, it is now widely believed that subluxation results when the. Even though it’s fun for the child, swinging them by their arms, hands or wrists puts them at risk of a pulled elbow. It will not cause any long-term damage to your child. (A) The posteriorly dislocated elbow is supinated (movement 1) to unlock the radial head from behind the capitellum. Additional indications are the treatment of associated fractures, existing open injury or the investigation of neurovascular compromise. It is usually the result of a fall onto an outstretched hand, often with a large amount of force involved. After closed reduction, exercises to improve range of motion must be performed. If an elbow dislocation is associated with a fracture (fracture-dislocation), it is called "complex." This is maintained for a period of 3 weeks in the majority of first time dislocators. Their arm may simply hang by their side. Posterolateral dislocation of the elbow is typically the result of indirect trauma and most frequently occurs as the result of a fall on the outstretched hand. 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. Severe ulnar nerve injury is less common now than previously described owing to the increasing recognition that entrapment of the medial epicondyle within the joint may also trap the ulnar nerve.18 Ulnar nerve injuries are usually transient.

The principle of reduction is to counteract the muscle forces that are maintaining the dislocation. It is rarely seen before the age of 3, and is not a very common injury. The diagnosis of a lateral condyle fracture can be challenging. These are the brachialis and biceps anteriorly and the triceps posteriorly. 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. Posterolateral dislocation of the elbow is typically the result of indirect trauma and most frequently occurs as the result of a fall on the outstretched hand. It can happen more than once, and it may occur several times in children who have particularly loose joints. Leave the room to allow the child time to start using the arm. A pulled elbow is caused by a sudden pull on a child's lower arm or wrist, for example when a child is lifted up by one arm. Arterial damage to the main brachial trunk is rare. In most cases, children with a pulled elbow will cry immediately after the sudden pull, and not use the injured arm at all. The major predisposition is the laxity of the toddler’s annular ligament combined with their behaviour. Signs and symptoms of a dislocated elbow. If the child is still unable to move his/her hand normally, the doctor will repeat the reduction. 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. The annular ligament may simply be stretched or partially torn, and occasionally subluxates into the radiocapitellar joint (Fig. Your child’s doctor will treat nursemaid elbow through a process called reduction. Radial head dislocations occur in conjunction with ulnar fractures (the Monteggia fracture–dislocation), while proximal ulnar dislocations are very rare in the adult population, and have never been reported in children. The medial structures of the elbow joint are integral to joint stability, and axial force from a fall is transmitted to the medial elbow by the medial crista of the trochlear, exaggerating the natural valgus carrying angle of the 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). Formal physiotherapy is not necessary for the majority of children, who will quickly regain normal motion and function. The success rate of manipulation is very high and all pulled elbows appear eventually to self-relocate, without any long-term sequelae. Anteroposterior (AP) radiographs show the distal humerus superimposed distally over the proximal forearm, with the proximal radius and ulna usually displaced in a posterior and lateral direction. 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. Parent of the child often describes that when they were trying to lift child holding the hand they heard a click like sound and the elbow become dislocated. Recurrent episodes occur in 5–39% of children until the annular ligament becomes stronger and stiffer. Pediatric elbow dislocation, by itself, occurs in older children between 10-15 years of age. Less common fractures occur to the coronoid and medial condyle. In this chapter we will discuss the management of pulled elbow, elbow dislocations and the Monteggia fracture–dislocation of the radial head. Patients with a dislocated elbow usually experience sudden severe pain at the time of injury. 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. It usually happens when you pull children by their hands. 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. When all of t… As Mercer Rang wryly observed, the wonder is not that some children get a pulled elbow but that ‘it is remarkable that not all children experience a pulled elbow’.1. Brachialis is at risk of rupture during dislocation, but also during relocation if the forearm is hyperextended to aid reduction. Indeed, if not free to do so, these osseous landmarks are at risk of fracture. To unlock the radial head and coronoid process from behind the distal humerus, some authors have previously advocated initial hyperextension. You will be advised if this is necessary. They are therefore useful only to exclude other injuries. Once a pulled elbow has been treated, your child should be able to return to normal activities. 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. A typical history and examination obviates the need for any investigations. Ultrasonography can provide inconsistent results8 and is very rarely used in our emergency department. The toddler tries to go in one direction, while the parent pulls in another. Seek immediate medical assistance, because the longer the elbow has been out of place, the more painful and difficult it is to put back into place. (B) The supinated forearm then has traction (2 and 3) applied to it via either a push (on the olecranon) or a pull technique. This relationship is maintained in supracondylar fractures, but lost in elbow dislocations (the apex normally moving posterolaterally). Figure 13.1 Typical mechanism of a child falling on an outstretched hand, which can result in various injuries to the upper limb. Much less common are posteromedial, medial, lateral or anterior dislocations. We present the case of an 11-year-old girl with an elbow dislocationtreated by closed manual reduction. One technique to relocate a dislocated elbow with anatomy diagrammed out. Indications for open reduction include failed closed reduction. The head of the radius subluxates distally but not beyond the equator, or maximal circumference, of the head. A pulled elbow will be put back into place by a nurse practitioner or doctor. Failed closed reduction in the emergency department is distressing for children and parents. A complete neurovascular examination of the affected limb must also be completed and documented prior to manipulation, with particular reference to the distal vascular supply, and the sensorimotor distribution of the median and ulnar nerves. Originally it was thought that the injury occurred with the elbow extended and the forearm supinated. Flexion at the elbow may also be required. Falls on the outstretched hand are common in childhood and occur in some toddlers on a daily basis. Median nerve entrapment may occur during reduction, as originally described by Hallet.15. Teach others who care for your child, such as grandparents and child care workers, the correct way to pick up your child. Dislocated elbow in child also termed as a pulled elbow in toddler is a condition in which elbow joint of the child dislocates. It should always be managed by a medical professional. In a randomized control trial, parents perceived this technique to be less painful for their child.7, Recurrent episodes occur in 5–39% of children until the annular ligament becomes stronger and stiffer.10,11 Age at initial presentation of less than 24 months is a risk factor for recurrent subluxation,12 and some advocate immobilizing all manipulated elbows in a flexed and supinated position for 2 days to ensure a successful outcome.13. Originally it was thought that the injury occurred with the elbow extended and the forearm supinated. 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. pediatric elbow dislocations usually occur in older children (10-15 years) and can be associated with other elbow fractures including a medial epicondyle fracture with an incarcerated intra-articular bone fragment. The majority of elbow dislocations are managed by closed reduction. Radial head subluxations are discussed with a focus on current evidence for imaging, reduction techniques, and follow-up. When the elbow dislocates, the proximal radio-ulnar joint (PRUJ) may remain intact or may be disrupted. These are the brachialis and biceps anteriorly and the triceps posteriorly. Chapter 13 Dislocations of the Elbow in Children, ‘Pity the young surgeon whose first case is a fracture around the elbow.’. There is no relationship between the radial head and the capitellum, but the relationship between the radius and ulna is maintained. Disruption of the posterior capsule may also occur and contribute to the risk of recurrent dislocation. Three complications of elbow dislocations that must be appreciated and require operative management: neurovascular compromise, associated fractures, open fractures Simple, uncomplicated dislocations can be treated with closed reduction, splinting and orthopedic follow up in 1-2 weeks Having a pulled elbow doesn’t cause any long-term damage and won’t stretch the ligament. These are the brachialis and biceps anteriorly and the triceps posteriorly. 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 . The majority of elbow dislocations are managed by closed reduction. The most common dislocation is posterior and may be accompanied by almost any fracture or combination of fractures, the most frequent being fracture separation of the medial epicondyle, fracture of the lateral condyle and fracture of the radial neck. 13.6A, B). 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. Reduction is obtained by gently supinating the child’s forearm with one hand and applying gentle pressure over the radial head with the other. (C) AP and (D) lateral post-reduction radiographs showing an enlocated elbow joint. Radiological examination is reserved for atypical presentations and failed primary treatment. My child loves it when I swing her by the hands when we are playing. PMID: 30921172 [Indexed for MEDLINE] Publication Types: Review; MeSH terms. The child sits on the parent’s lap, and the affected limb is grasped at the wrist. Is this dangerous? Isolated dislocation of the radial head is uncommon. The child presents with a swollen elbow and limited movement. 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. 13.1). When the injury occurs: The child usually begins crying right away and refuses to use the arm because of elbow pain. mechanism for posterolateral dislocation . The child regained satisfactory range-of-motion of the elbow with complete bony union within 3 months. Figure 13.5 (A) The posteriorly dislocated elbow is supinated (movement 1) to unlock the radial head from behind the capitellum. 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.25. A pulled elbow will not cause any long-term damage to your child if treated promptly and appropriately. After 3 weeks, the plaster slab is removed and the child is allowed to freely mobilize the elbow. 72,118 In general, however, because the attachments of ligaments and muscles are stronger than the adjacent growth plate, forces exerted about most joints tend to result in epiphyseal injury rather than simple dislocation of the adjacent joint. If my child has had a pulled elbow once, is he more likely to have it again because his ligament has stretched? Failed manipulation or delayed return in using the arm should prompt a search for other injuries and include repeat examination and radiographs. When it remains intact, the most common finding is a posterolaterally displaced radius and ulna in relation to the distal humerus. 13.1).2 The most common site of injury is the wrist and hand, with the elbow region accounting for approximately 10% of the total. 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. Your doctor probably put a splint on your child's elbow. If it goes beyond this point, studies show that reduction becomes difficult, and these may go on to Monteggia type fracture–dislocations of the forearm with dislocation of the radial head.6. However, if the elbow was partially dislocated for quite a while, then your child may need some pain medicine for a day or two. The child will move the shoulder, but not the elbow. Primary ligament repair is not an appropriate indication as studies have shown that the outcome is inferior to closed treatment.21,22. Elbow, dislocation, children, injuries, outcome INTRODUCTION Paediatric traumatic elbow dislocation, is an uncommon injury1. The majority of elbow dislocations are managed by closed reduction. 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. The child holds the elbow in the extended position, typically not in any great distress, but refuses to move the affected limb, (the phenomenon of ‘pseudoparalysis’). Fractures and Dislocations about the Elbow in the Pediatric Patient Amy L. McIntosh, MD . 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. In addition, the coronoid process is also at risk of fracturing. A study of 1579 elbow injuries in skeletally immature individuals from Gothenberg, Sweden, found only 45 dislocations, giving a prevalence of only 3%. This information is intended to support, not replace, discussion with your doctor or healthcare professionals. There may be signs of generalized joint laxity in the child and in one or both parents. 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. However, some children are more susceptible to getting a pulled elbow more than once because they have loose joints and their radius bone is more likely to slip out. 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. Regional anesthesia may be used (eg, axillary nerve block) but has the disadvantage of limiting post-reduction neurologic examination. Additional indications are the treatment of associated fractures, existing open injury or the investigation of neurovascular compromise. Lateral radiographs confirm a posterior dislocation of the elbow (Fig. 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. 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. Rehabilitation is essential in either the surgical or non-surgical treatment of elbow fracture-dislocations. Follow the advice of the nurse or doctor, or see our fact sheet Pain relief for children. If a fracture has been identified or is suspected, access to fluoroscopy will normally dictate transfer to the operating theatre. 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. A collar and cuff are applied to support the plaster slab. Examination may reveal tenderness over the radial head and annular ligament. A doctor can put your child's elbow back in place. Indications for open reduction include failed closed reduction. Falling onto the outstretched hand in a child aged 12–14 years is a common cause of elbow dislocation. (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.
